A. Infrastructure Overview

Currently, the university operates two sewage treatment plants, each with a capacity of 250 KLD—one dedicated to the Men’s Hostel and the other serving the institute campus. This infrastructure is critical for managing sewage, which typically contains a mix of organic, inorganic, and suspended solids. The treatment process is structured to remove these pollutants, allowing for effective reuse of the treated water.

Figure VI (3.1) – 1: 250 KLD and 100 KLD – STP – Geo-tagged photographs

B.Treatment Process

The treatment system comprises several stages, beginning with preliminary treatment to eliminate floating debris and grit. Bar screens filter out plastics and other floating materials, while grit chambers remove sand and silt. The primary sedimentation tank further aids in the removal of suspended solids. Following this, the secondary treatment process employs a biological treatment system to remove organic content from the wastewater.

Eco-bio blocks are incorporated to enhance the efficiency of biological treatment. These blocks facilitate the attachment of beneficial bacteria, improving the removal of organic matter and enabling the system to handle fluctuations in organic loading. The treatment process operates on the principle of an attached growth aerobic system, followed by sand and carbon filters that ensure any residual organics are adequately adsorbed before the treated water is stored in a collection tank.

Figure VI (3.1) – 2: Geo-tagged photographs showing two STPs of capacity 250 KLD and 100 KLD

C. Maintenance and Monitoring

Regular maintenance of the sewage treatment plants is a priority, with periodic checks on all pumps and valves to ensure optimal functioning. The treated water is primarily utilized for landscaping and toilet flushing, significantly reducing the university’s dependence on fresh water from wells for gardening purposes.

To ensure the effectiveness of the treatment systems, the physical, chemical, and biological characteristics of the treated water are routinely tested. Key parameters such as pH, solids, Chemical Oxygen Demand (COD), biochemical oxygen demand (BOD), nitrates, and chlorides are monitored to maintain water quality suitable for reuse.

1.OVERALL LAYOUT
  • The map depicts the campus layout, highlighting key buildings and areas. Various color-coded lines represent different water types and their management systems.
2. COLOR-CODED SYSTEMS
  • Raw Water Lines (Green): These lines indicate the pathways through which untreated or source water is supplied to the campus. This water is typically drawn from local sources before any treatment process.
  • STP Treated Water Lines (Yellow): The yellow lines represent water undergoing treatment through the Sewage Treatment Plant (STP). This recycled water is suitable for non-potable uses, such as irrigation and cooling processes, reflecting the institution’s sustainability efforts.
  • Sewage Water Lines (Blue): The blue lines illustrate the sewage discharge routes, showing how wastewater is collected and directed to the treatment plant for processing. This ensures effective sanitation and environmental management.
3. INFRASTRUCTURE ELEMENTS
  • The diagram highlights important infrastructure components, such as the Sewage Treatment Plant (STP), water tanks, and other critical facilities. These components are strategically located to optimize water flow and management across the campus.
4. OVERALL FUNCTIONALITY
  • The design emphasizes an integrated approach to water management, showcasing how raw water is sourced, treated, and utilized effectively while also addressing sewage disposal. This organized system reflects the institute’s commitment to sustainability and efficient resource use.

The map serves as a valuable tool for understanding the water management framework at B.S. Abdur Rahman Crescent Institute of Science and Technology. By clearly outlining the raw water, treated water, and sewage systems, it provides insight into the institution’s initiatives for maintaining water quality and promoting environmental sustainability on campus.

5. PREVENTIVE MEASURES

  • Our past experience has shown that remedial actions to clean up polluted sites and water bodies are more expensive than applying measures to prevent pollution. Although a wastewater treatment system has been installed, water pollution remains a problem. Our approach is to prevent the production of wastes from various sources. The following preventive measures have been applied on campus.
    • To prevent Kitchen wastewater FOG (Fats, Oils, and Grease) entering the water system

      • Kitchen wastewater, especially from Men’s Hostel kitchen, contains high levels of FOG that can clog sewer systems and inhibit biological activity in treatment plants.
      • Issues caused by improper discharge of FOG:
        • FOG forms a layer on the water surface, reducing light penetration and oxygen transfer, disrupting aquatic ecosystems.
        • FOG solidifies and accumulates in sewer pipes, causing blockages and sanitary sewer overflows.
        • FOG interferes with wastewater treatment, especially in activated sludge processes.
      • Action: A 25 kLD kitchen wastewater FOG treatment plant has been installed to remove pollutants like cooking oils, fats, and food scraps before discharge to the STP. This plant uses a multi-stage process (grease trap plus chemical and filtration steps) to break down and remove contaminants from kitchen wastewater.

Figure VI (3.2) – 2: 25 kLD FOG treatment plan

    •  To prevent sewage water entering the water system
      • A 10 kLD decentralized Sewage Treatment Plant (STP) has been installed for Crescent Incubation Center (CIIC Block) to treat wastewater generated from CIIC Block so it can be reused for non-potable purposes like gardening.
      • This STP provides a self-contained system for the CIIC block where connecting to a main sewer line is not feasible due to distance and terrain.
      • This approach conserves fresh water and prevents environmental pollution from untreated sewage in septic systems.
      • A decentralized FRP-based STP has been installed to address frequent filling of the existing septic tank, preventing sewage percolation into the ground.

B. LAYOUT OF PIPELINES FOR WATER AND WASTEWATER (FIGURE VI – 2)

  1. PLUMBING AND WATER COLLECTION SYSTEMS
    • The institute has established a meticulously planned plumbing facility for the collection and treatment of water. This includes the transportation of water from wells to treatment units, ensuring that pipes are laid at suitable gradients to facilitate safe water transport.
    • Regular inspections are conducted to check for leaks in the water pipelines, and immediate replacements are made in case of breakages due to accidents. This proactive maintenance helps prevent polluted water from entering the water system.
  2. SEPARATE SEWER SYSTEMS
    • Wastewater is collected through separate sewer pipelines, which are equipped with sufficient manholes for easy inspection. This segregation ensures that wastewater does not mix with potable water sources, thereby reducing the risk of contamination.
  3. IDENTIFICATION AND MARKING OF PIPELINES
    • The institute employs a colour-coded system for easy identification of water and sewer lines:
      • Green: Raw water from wells
      • Blue: Treated water from the Sewage Treatment Plant (STP) used for toilet flushing
    • This clear marking helps prevent accidental cross-connections that could lead to pollution.

C. SOLID WASTE MANAGEMENT PRACTICES (FIGURE VI – 3)
 
  1. PREVENTIVE MEASURES AGAINST POLLUTION
    • The institute has implemented robust solid waste management practices to prevent water pollution caused by improper waste disposal. Key measures include:
      • Segregation of Garbage: Garbage is segregated at entry points, particularly from high-traffic areas like hostels and canteens, to minimize contamination risks.
      • Minimization of Waste: Efforts are made to reduce the amount of waste, particularly plastics, that could clog pipelines and affect water quality.
      • Regular Clearing of Dumping Yards: Frequent disposal of accumulated waste from dumping yards prevents overflow and potential leaching into the water system.
  2. SEWER MANAGEMENT
    • The sewer connections to the old biogas plant have been redirected to the STP, ensuring that there is no mixing of sewer and rainwater, which could lead to contamination.
  3. BOUNDARY MANAGEMENT
    • Measures have been taken to close any holes along the boundary of the institute that could contribute to water seepage from neighbouring areas, further protecting the water system from external pollution sources.
  4. EMERGENCY PREPAREDNESS
    • The institute has additional raw water storage tanks that can be utilized during emergencies, ensuring a reliable supply of clean water and reducing the risk of contamination during unforeseen incidents.

    • TNPCB drinking water limits are not explicitly cited here, but high TDS (1128 mg/L) may exceed typical drinking water recommendations (IS 10500 provides guidance; often aims for <= 1000 mg/L). The BOD/COD values appear reasonable.
  • STP Treated Water: pH 7.63–7.71; TDS 1028–1128 mg/L; TSS BD L; BOD 3.0–3.5 mg/L; COD 17–19 mg/L; Oil & Grease BD L.
    • Non-compliance noted for some samples (the August 16, 2025 report indicates “Not Comply with drinking water specification as per IS:10500:2012” for some parameters). In the “Treated Outlet as per TNPCB” table, pH within range; TDS and other parameters may require monitoring.

E. Campus Canteen / Well Water samples

  • Turbidity in canteen/well water samples generally within acceptable limits (BDL to 1.2 NTU).
  • TDS ranges 38–898 mg/L depending on the source/outlet; some high values observed (e.g., 898 mg/L).
  • Chloride: 13–241 mg/L.
  • Sulphate: 4.5–153 mg/L.
  • Free Residual Chlorine: BD L to Nil (acceptable in distribution systems where chlorine is not required for non-potable uses; for drinking water, residual chlorine is typically desired).
  • Total Iron: 0.1–1.89 mg/L (some samples exceed 1.0 mg/L; IS 10500 allows up to 0.3 mg/L for iron? Actually IS 10500 does not specify a strict mg/L limit for iron; many guidelines cite 0.3 mg/L as a limit for iron in drinking water; however the IS 10500 standard for iron is 0.3 mg/L? The data here uses “1.0” as a test method standard; please verify local limit if needed.)
  • Calcium/Magnesium: within typical ranges in most entries, some values show magnesium up to 150 mg/L.

F. PM: STP Treated Water

  • pH around 7.63–7.71; TDS around 1028–1128 mg/L; BOD 3.0–3.5 mg/L; COD 17–19 mg/L; Oil & Grease BD L; Silica ~12–15.9 mg/L; Free Chlorine BD L or Nil.
  1. Observations and potential issues
  • TDS variability is significant across samples, with several readings well above 600 mg/L (some up to ~1128 mg/L). IS 10500 allows general use drinking water with TDS values typically acceptable up to around 1000 mg/L, but the precise limit depends on use and local norms. Consider post-treatment polishing or source evaluation if drinking water usage is intended for those higher-TDS samples.
  • Free residual chlorine is often BD L or very low. If disinfection residual is required for safety, ensure that chlorination is maintained at recommended levels (commonly 0.2–0.5 mg/L) in distribution points.
  • For some samples, Calcium Hardness and Magnesium Hardness values are relatively high (e.g., Calcium hardness 60–110 mg/L in some lines; Magnesium hardness up to 150 mg/L). While not always disqualifying, elevated hardness may affect taste/softness and scaling. Consider water softening if softness is required for specific processes or consumer acceptance.
  • Iron levels in some samples are BD L to 1.89 mg/L; if IS 10500 is applied strictly, iron limit is around 0.3 mg/L (check latest local limit). If used for drinking water, consider iron removal (filtration/oxidation) where needed.
  1. Recommendations
  • For drinking water outlets showing higher TDS (e.g., > 1000 mg/L), assess source water quality and consider post-treatment steps such as reverse osmosis polishing, ion exchange, or blending with lower-TDS sources to meet recommended drinking water standards.
  • Ensure residual chlorine distribution targets are met for safety, particularly at service taps. Regular monitoring and adjustment of disinfection dosing.
  • Implement routine microbiological checks (as already performed) with a frequency aligned to supply reliability and occupancy; maintain zero total coliforms and E. coli per IS 10500.
  • Review hardness and mineral balance for processes or consumer preference; if taste/scale is an issue, consider softening or remineralization steps as appropriate.
  • Maintain documentation of sampling points and ensure samples are taken consistently at representative points (e.g., post-RO output, distribution taps, well water upstream of treatment, etc.)

C. ENVIRONMENT, GREEN, AND WATER AUDIT PROCESS: A COMPREHENSIVE OVERVIEW 

B.S. Abdur Rahman Crescent Institute of Science and Technology has developed a multifaceted approach to water management, focusing on diverse sources, efficient storage, and effective distribution systems. The institution utilizes a range of water sources, including reverse osmosis (RO) water for drinking purposes, bore water sourced from depths of up to 300 feet at prominent locations such as the Science Block, and multiple open wells strategically placed near hostels and the main canteen. Additionally, the college incorporates lorry water delivered  and an extensive rainwater harvesting system (RWHS) deployed across various building blocks to capture runoff and enhance groundwater levels.

The college employs a detailed analysis of its water utilities to optimise water usage and storage, as outlined in a comprehensive report. For instance, the Main Building includes an underground sump with 80 kilolitres (KLD) capacity, supported by robust motor systems that enable efficient water delivery to multiple sub-units, including the MBA and Canteen blocks. In contrast, the Men’s Hostel features an impressive 1,100 KLD capacity, ensuring adequate supply for residents. Regular maintenance is integral to this system, with the management team ensuring that overhead tanks and storage facilities are cleaned every six months, thus guaranteeing the quality and safety of the water supplied throughout the campus.

The institution places considerable emphasis on sustainability, particularly through its rainwater harvesting initiatives. Rainwater is collected from building rooftops and routed via an effective piping system to dedicated pits that promote groundwater recharge. Plans are underway to expand the number of rainwater harvesting pits and conduct GIS studies to monitor improvements in the groundwater table over time. Such measures highlight the proactive role that B.S. Abdur Rahman Crescent Institute plays in enhancing water conservation and management practices while also addressing community needs through increased water availability.

Off-Campus Water Conservation Support

A. VETIVER PLANTING TO REDUCE WATER POLLUTION: LOCAL COMMUNITY ENGAGEMENT AND ENVIRONMENTAL BENEFIT (03RD AUGUST, 2023)

 

Community-driven action by National Service Scheme (NSS) volunteers from B.S. Abdur Rahman Crescent Institute of Science & Technology, in collaboration with local authorities, targeted sewage-induced water pollution in the 27-foot-deep Urapakkam Kolatchiammal temple pond. The intervention focused on planting Vetiver grass along pond banks and upstream catchment areas to stabilize soil, reduce erosion, filter runoff, and enhance infiltration, thereby limiting pollutant transport to the pond. NSS volunteers from B.S. Abdur Rahman Crescent Institute of Science & Technology, alongside participants from SRM University, SRM Valliammai Engineering College, and Aadhi Engineering College, worked with local authorities to implement the plan. Vetiver’s deep, dense, fibrous root system is central to the approach, as it improves soil stability and infiltration, reduces surface runoff, and exhibits pollutant-retention properties. Expected outcomes include reduced sediment and nutrient loads entering the pond, improved groundwater recharge, and long-term soil rehabilitation around the watershed.

COMMUNITY AND GOVERNANCE FOCUS

The Urapakkam Kolatchiammal Temple pond faces long-standing sewage discharge from nearby residences, with unauthorized connections channeling wastewater into stormwater drains that should carry only rainwater. This situation contaminates the pond, accelerates sedimentation, risks eutrophication, and degrades water quality, potentially affecting local biodiversity and the pond’s cultural and community uses. The pollution also poses health risks to nearby residents and undermines the pond’s aesthetic and communal value. Addressing these issues requires a dual approach: managing soil erosion and runoff at the watershed level while simultaneously tackling sewage leakage through governance and infrastructure improvements.

EMPHASIS ON EDUCATION AND STEWARDSHIP

The primary objective is to reduce pollutant loads entering the pond by enhancing soil stability and filtering runoff at the source and along runoff pathways. A secondary aim is to improve soil health and infiltration around the pond to promote groundwater recharge and resilience against erosion. The intervention also seeks to foster collaborative learning and stewardship by involving NSS volunteers from multiple institutes and linking community action with local authorities, thereby building a model for cross-institutional watershed management and pollution prevention.

INTERVENTION DETAILS

Vetiver grass (Chrysopogon zizanioides) was introduced along the pond’s banks and in key erosion-prone zones within the upstream catchment. NSS volunteers from B.S. Abdur Rahman Crescent Institute of Science & Technology and partner institutions, under guidance from local authorities, participated in planting Vetiver. Vetiver was chosen for its deep, dense, and fibrous root system that stabilizes banks, reduces runoff velocity, and improves soil porosity and infiltration in compacted soils. Additionally, Vetiver can act as a biofilter, supporting microbial communities in the rhizosphere that aid in pollutant degradation and sequestration, including uptake of certain nutrients and heavy metals. Planting sites focused on the pond’s banks, upstream catchment areas, and zones most susceptible to runoff entry points.

MECHANISMS BY WHICH VETIVER REDUCES WATER POLLUTION

Vetiver reduces water pollution through several interrelated mechanisms. Its extensive root network anchors soil, significantly reducing bank instability and sediment entrainment during rainfall. Dense vegetative cover slows runoff, promotes infiltration, and lowers both the volume and velocity of runoff that would otherwise transport sediments and attached pollutants to the pond. As a biofilter, Vetiver’s root zone traps particulates and supports uptake of nutrients such as nitrogen and phosphorus, thereby reducing nutrient leakage to the water body. Improved soil structure from root penetration enhances infiltration rates, further diminishing surface runoff. Infiltration improvements also aid groundwater recharge, contributing to watershed resilience. Vetiver’s low-maintenance, drought-tolerant characteristics make it a robust, scalable solution for interfaces between rural and urban environments, supporting long-term sustainability.

EXPECTED ENVIRONMENTAL AND COMMUNITY BENEFITS

The initiative is anticipated to yield several benefits: improved pond water quality through reduced turbidity and nutrient loads; decreased sedimentation, which enhances the pond’s storage capacity and ecological health; strengthened ecosystem resilience with better habitat conditions around the pond; and empowered communities through NSS-led engagement that raises awareness about pollution sources and promotes responsible waste disposal. The approach also holds promise for informing local watershed management plans and anti-pollution strategies, particularly when integrated with proactive sewage management and enforcement of wastewater discharges.

E. VETIVER PLANTING TO REDUCE WATER POLLUTION: LOCAL COMMUNITY ENGAGEMENT AND ENVIRONMENTAL BENEFIT (03RD AUGUST, 2023)

Community-driven action by National Service Scheme (NSS) volunteers from B.S. Abdur Rahman Crescent Institute of Science & Technology, in collaboration with local authorities, targeted sewage-induced water pollution in the 27-foot-deep Urapakkam Kolatchiammal temple pond. The intervention focused on planting Vetiver grass along pond banks and upstream catchment areas to stabilize soil, reduce erosion, filter runoff, and enhance infiltration, thereby limiting pollutant transport to the pond. NSS volunteers from B.S. Abdur Rahman Crescent Institute of Science & Technology, alongside participants from SRM University, SRM Valliammai Engineering College, and Aadhi Engineering College, worked with local authorities to implement the plan. Vetiver’s deep, dense, fibrous root system is central to the approach, as it improves soil stability and infiltration, reduces surface runoff, and exhibits pollutant-retention properties. Expected outcomes include reduced sediment and nutrient loads entering the pond, improved groundwater recharge, and long-term soil rehabilitation around the watershed.

COMMUNITY AND GOVERNANCE FOCUS

The Urapakkam Kolatchiammal Temple pond faces long-standing sewage discharge from nearby residences, with unauthorized connections channeling wastewater into stormwater drains that should carry only rainwater. This situation contaminates the pond, accelerates sedimentation, risks eutrophication, and degrades water quality, potentially affecting local biodiversity and the pond’s cultural and community uses. The pollution also poses health risks to nearby residents and undermines the pond’s aesthetic and communal value. Addressing these issues requires a dual approach: managing soil erosion and runoff at the watershed level while simultaneously tackling sewage leakage through governance and infrastructure improvements.

EMPHASIS ON EDUCATION AND STEWARDSHIP

The primary objective is to reduce pollutant loads entering the pond by enhancing soil stability and filtering runoff at the source and along runoff pathways. A secondary aim is to improve soil health and infiltration around the pond to promote groundwater recharge and resilience against erosion. The intervention also seeks to foster collaborative learning and stewardship by involving NSS volunteers from multiple institutes and linking community action with local authorities, thereby building a model for cross-institutional watershed management and pollution prevention.

INTERVENTION DETAILS

Vetiver grass (Chrysopogon zizanioides) was introduced along the pond’s banks and in key erosion-prone zones within the upstream catchment. NSS volunteers from B.S. Abdur Rahman Crescent Institute of Science & Technology and partner institutions, under guidance from local authorities, participated in planting Vetiver. Vetiver was chosen for its deep, dense, and fibrous root system that stabilizes banks, reduces runoff velocity, and improves soil porosity and infiltration in compacted soils. Additionally, Vetiver can act as a biofilter, supporting microbial communities in the rhizosphere that aid in pollutant degradation and sequestration, including uptake of certain nutrients and heavy metals. Planting sites focused on the pond’s banks, upstream catchment areas, and zones most susceptible to runoff entry points.

MECHANISMS BY WHICH VETIVER REDUCES WATER POLLUTION

Vetiver reduces water pollution through several interrelated mechanisms. Its extensive root network anchors soil, significantly reducing bank instability and sediment entrainment during rainfall. Dense vegetative cover slows runoff, promotes infiltration, and lowers both the volume and velocity of runoff that would otherwise transport sediments and attached pollutants to the pond. As a biofilter, Vetiver’s root zone traps particulates and supports uptake of nutrients such as nitrogen and phosphorus, thereby reducing nutrient leakage to the water body. Improved soil structure from root penetration enhances infiltration rates, further diminishing surface runoff. Infiltration improvements also aid groundwater recharge, contributing to watershed resilience. Vetiver’s low-maintenance, drought-tolerant characteristics make it a robust, scalable solution for interfaces between rural and urban environments, supporting long-term sustainability.

EXPECTED ENVIRONMENTAL AND COMMUNITY BENEFITS

The initiative is anticipated to yield several benefits: improved pond water quality through reduced turbidity and nutrient loads; decreased sedimentation, which enhances the pond’s storage capacity and ecological health; strengthened ecosystem resilience with better habitat conditions around the pond; and empowered communities through NSS-led engagement that raises awareness about pollution sources and promotes responsible waste disposal. The approach also holds promise for informing local watershed management plans and anti-pollution strategies, particularly when integrated with proactive sewage management and enforcement of wastewater discharges.

Brief details about the programme:

Guest Lecture on “Water for Peace – World Water Day 2024”,was organized by the Institution of Engineers (India), Kancheepuram Local Centre in association with the Department of Civil Engineering, School of Infrastructure, B.S.Abdur Rahman Crescent Institute of Science & Technology on 21stMarch 2024 as part of World Water Day Celebrations. Dr.Vasanthi Padmanabhan, Professor & Student Advisor IE(I) School of Infrastructure, B.S.Abdur Rahman Crescent Institute of Science & Technology welcomed the chief guest Dr.Sekhar Raghavan (Rain Man), the honorary secretary of IE(I) – KLC Dr.S.Karthikeyan, and the audience. She appraised the importance of conserving and effectively storing the rainwater and available water for the future use. Dr.S.Karthikeyan, honorary secretary IE(I) felicitated the gathering and briefed the essential role of water in our human life and its importance. He stated that the Institution of Engineers (India) is the National organization of engineering professionals in India. It is the largest multi-disciplinary engineering professional society. He insisted everyone to become member of IEI and encouraged the students to apply for the project proposal for which the fundings are given in order to motivate the students.

About the Lecture

      Dr.Sekhar Raghavan is the Director of Rain centre at Adyar, Chennai which was been inaugurated by the Former Chief Minister Late. Dr.J.Jayalalitha. Dr.Sekhar Raghavana is also known as Rain man. The speaker started the lecture explaining the need, relevance and importance of rainwater harvesting. During his lecture he explained to students about his initiating the rain centre which was a part of his Akash Ganga Trust that spreads awareness about rainwater conservation in a country that thirsts for water yet allows the precious fluid to go waste. Hence a universal access to water still remains an issue in India and in particular in Chennai. He also shared his experience in bridging the gaps between society and rainwater harvesting in his life long journey to keep the water-tables high and the groundwater sweet (as opposed to salty groundwater due to over-use and seawater ingress). In this case moving forward to the future generation and needs. It’s that time of year when we should start worrying about our rain water harvesting systems and get them ready for the coming rains. The speaker shared about the most common problems that can be expected in RWH structures for which he has given few tips to follow. The issues are deposit of silt picked up by rainwater from dirty rooftops and driveways. Take preventive measures like pruning tree branches, empty and clean the filters, wash, dry and fill them. Regularly check the roof top pipes for leaks and replace where necessary. Finally, the speaker concluded by saying save rainwater as it is free. Around 70 students from IV and VI semester B.Tech, Civil Engineering participated in the event and got benefited. This lecture was useful and compliments the UG courses viz. CEDX 53 – Stormwater and Flood management, CEDX 51 –Hydrology and CED 2205 –Water Resources Engineering.

B. CAMPUS GUIDELINES AND OPERATIONAL PROTOCOLS

 

Enhance water-use efficiency comprehensively across various sectors and guarantee the sustainable extraction and provision of freshwater. B.S. Abdur Rahman Crescent Institute of Science and Technology has released guidelines and operational protocols aimed at minimizing water usage.

WATER AND WASTE MANAGEMENT

SAVE WATER

 There is no life without water. Water is not only important for human beings but for the entire ecosystem. Hence prioritizing water management helps us to eliminate water waste and keep our water infrastructure operating in peak condition. Therefore, we kindly request our staff and students to close the water taps immediate after usage.

WASTE MANAGEMENT

Maintaining a clean environment is indeed a great place to live. If we keep our premises neat & clean in-turn our mind will be fresh and campus ambiance will be good, therefore we request our staff and students of our campus to drop the waste item in appropriate dustbins placed in the campus.

SIGNAGE BOARD(S)

Water is becoming a costly commodity and 80 % of the water requirements of this campus are met by the out sourced contract. As a result, we are promoting the conscious usage of water by all the stakeholders of the campus viz., students, scholars, faculty members, supporting staff and their families.

Promoting Conscious Water Usage in the Wider Community
A.LAKE CLEAN-UP WITH SEED BALL PLANTATION IN ASSOCIATION WITH ENVIRONMENTALIST FOUNDATION OF INDIA (EFI) (04th OCTOBER, 2023)

B S Abdur Rahman Crescent Institute of Science & Technology, National Service Scheme organized the LAKE CLEAN-UP WITH SEED BALL PLANTATION in collaboration with the Environmentalist Foundation of India (EFI), brought volunteers together on 04.10.2023 at 10:00 am to revive a local water body in Kolapakkam village near Vandalur. This initiative underscores the dual aim of cleaning polluted lakes and restoring ecological balance through community-driven conservation. EFI’s science-based approach, paired with NSS’s youth leadership, highlights how practical, on-the-ground actions—such as removing litter and monitoring water quality—can catalyse broader environmental stewardship and neighborhood resilience against ongoing threats to freshwater ecosystems.

A key component of the effort was the deployment of seed balls, a simple yet effective method for reintroducing native vegetation to degraded landscapes. Comprising seeds, soil, clay, and organic materials, these seed balls can be scattered over hard-to-reach areas, facilitating natural germination and growth. As the seeds establish, they are expected to enhance soil health, reduce erosion, and promote biodiversity, ultimately supporting the lake’s ecological recovery. The event was coordinated by NSS Programme Officers Dr. C. Srinivasan, Dr. Noushad.C, and Dr. R. Anitha, with Dr. D. Ayub Khan Dawood serving as NSS Coordinator, reflecting a collaborative effort between faculty, students, and EFI to advance sustainable water management and habitat restoration in the region.

Lakes and ponds often bear the brunt of modern day human negligence. Most of India’s freshwater bodies are polluted/contaminated due to human activity. E.F.I focuses on scientific revival of these freshwater bodies through a community based collaborative conservation effort.

Overview

B.S. Abdur Rahman Crescent Institute of Science & Technology, in collaboration with the National Service Scheme (NSS), organized a community-centered environmental initiative titled “Lake Clean-Up with Seed Ball Plantation.” The event aimed to restore a locally polluted lake and initiate ecological restoration through seed-ball planting. Volunteers from NSS, including students and faculty, came together to demonstrate practical environmental stewardship and community resilience in the face of ongoing threats to freshwater ecosystems.

Partnership and Purpose

  • Partners: Crescent Institute and the Environmentalist Foundation of India (EFI).
  • Focus: Combine academic resources with community action to address lake degradation.
  • Activities: Litter removal, debris collection, and periodic water-quality monitoring, with seed-ball planting to promote habitat restoration.
  • Impact: Demonstrates how organized cleaning efforts can catalyze broader environmental stewardship and healthier lake ecosystems.

Why Lake Cleaning Matters

Lake pollution arises from human activities such as improper waste disposal, industrial effluents, agricultural runoff, and urban runoff. Cleaning and restoration yield multiple benefits:

  • Public health: Reduces waterborne diseases and exposure to hazardous substances.
  • Ecosystem restoration: Supports habitat recovery, biodiversity, and ecosystem services like flood control, groundwater recharge, and climate regulation.
  • Economic and social benefits: Boosts tourism, fishing, and community well-being; lowers potable-water treatment costs.
  • Resilience and sustainability: Regular cleanups, combined with prevention and waste management, strengthen resilience to climate change and urbanization.
  • Educational impact: Engages communities, raises environmental awareness, and empowers youth in conservation.

Seed Ball Plantation as a Core Intervention

A central component of the event was seed-ball deployment—a simple, scalable method for reintroducing native vegetation to degraded shoreline and lake-adjacent habitats. Seed balls consist of seeds, soil, clay, and organic binders, designed for easy dispersal in areas difficult to access with traditional planting. After dispersion, balls break down and germinate in suitable microhabitats, promoting natural regeneration. Expected benefits include improved soil structure, increased moisture retention, reduced shoreline erosion, enhanced biodiversity, and a gradual return of native flora to support local fauna and habitat resilience. This approach aligns with EFI’s community-driven restoration philosophy and complements ongoing conservation efforts in the region.

Role of NSS and EFI

  • Coordination: NSS Programme Officers Dr. C. Srinivasan, Dr. Noushad C., and Dr. R. Anitha; NSS Coordinator Dr. D. Ayub Khan Dawood led the event.
  • Collaboration: Faculty mentors, student volunteers, and EFI representatives worked together to ensure organized deployment, safe field activities, and integration of scientific guidance with hands-on action.
  • Impact: EFI provided the scientific framework for restoration, while NSS mobilized youth participation, fostering leadership, civic engagement, and environmental literacy.

Field Activities and Observations

  • Community Participation: A large turnout of students, faculty, and community members demonstrated solidarity and enthusiasm for environmental restoration.
  • Lake Clean-Up: Volunteers removed waste and debris from the lake perimeter and nearby pathways, yielding immediate improvements in cleanliness and sanitation.
  • Seed Ball Deployment: Seed balls were prepared and strategically dispersed across degraded shoreline zones to maximize germination potential and future vegetative cover.
  • Site Assessment: Visual observations indicated recovery potential, with seed-ball planting intended to complement existing restoration measures and encourage ongoing monitoring.

Impact and Future Prospects

The Lake Clean-Up with Seed Ball Plantation serves as a practical model of university–NGO collaboration to address local ecological challenges. Key outcomes include:

  • Immediate improvements in site cleanliness.
  • Long-term ecological benefits from native vegetation restoration and improved habitat structure.

B. DRIVEN BEACH AND COASTAL CLEAN-UPS

1: Water-Smart Beach Clean-Ups: Integrating Conservation into Community Action

Promoting conscious water usage across the wider community hinges on turning beach and coastal clean-up efforts into opportunities for sustained water stewardship. By foregrounding water conservation within every cleanup, communities can align environmental restoration with daily habits that protect aquatic health. Building on established NSS-led beach clean-ups and partnerships with NGOs, organize regular, well-publicized events that tackle plastic pollution—the most visible and direct threat to both water quality and marine life. When these events are designed to educate as they clean, participants leave with a clearer understanding of how reduced plastic waste translates into safer, healthier waterways for recreation, fishing, and everyday use.

2: From Cleanup to Change: Data-Driven Guidance for Everyday Water Stewardship

A data-informed approach strengthens the impact of these initiatives. Systematically tracking debris types and volumes during each cleanup enables communities to identify pollution sources and track trends over time. This data becomes a powerful tool for advocacy, informing targeted improvements in waste collection schedules, shoreline management, and public awareness campaigns. By translating findings into straightforward, actionable recommendations for residents—such as minimizing single-use plastics, ensuring proper disposal, and adopting water-conserving behaviors at home and during beach visits—the effort moves from episodic events to lasting behavioral change.

3: Broad Stakeholder Engagement: Expanding Reach and Resources

Engagement with a broad network of stakeholders is essential for scalability and resilience. Involve local fishing communities, schools, coastal residents, and environmental organizations to extend reach beyond campus boundaries. Leverage partnerships with NGOs and national campaigns (like Swachh Bharat and related initiatives) to amplify messaging and resources. Utilizing diverse channels—social media, short videos, and local media—helps share success stories, present debris data transparently, and offer practical tips for reducing plastic use and conserving water in daily life. Recognizing sustained volunteers with certificates and public acknowledgments can incentivize ongoing participation and nurture a culture of collective responsibility around water stewardship.

4: Building a Data-Driven Framework: Communicating Debris Insights to Residents

A data-driven, community-facing framework should underpin ongoing efforts. Collect and analyze debris data not only to inform local policy discussions with authorities about waste management scheduling and shoreline care but also to communicate findings in accessible formats that resonate with residents. Translate complex data into simple, actionable steps that individuals can implement at home and during beach visits. Regular, collaborative actions paired with transparent reporting create a long-term ethos of conscious water usage, turning coastal clean-ups into catalysts for healthier waterways and more resilient aquatic ecosystems.

5: Sustaining Momentum: Institutionalizing Water-Conscious Practices

To sustain momentum, embed these practices within local institutions and plans. Develop a schedule that ensures consistency in cleanup events and data collection, accompanied by regular briefings that connect the dots between plastic pollution, water health, and community well-being. Encourage schools and community organizations to adopt similar water-conscious practices, extending the reach and reinforcing the message across generations. In doing so, communities not only improve shoreline conditions but also cultivate a proactive culture that prioritizes clean water, protected ecosystems, and a shared sense of stewardship for coastal environments.
