The Mamallan Reservoir Project

The Mamallan Reservoir was proposed by the Tamil Nadu Water Resources Department and formally launched by the previous DMK government led by M.K. Stalin in January 2026.

Planned in the Kovalam sub-basin near Nemmeli in Chengalpattu district, the reservoir would extend across parts of Tiruporur and Thirukazhukundram taluks, between East Coast Road and Old Mahabalipuram Road.

1. Estimated project cost: approximately ₹342.60 crore
2. Project area: roughly 5,100 acres
3. Proposed daily supply: up to 170 MLD, or 17 crore litres

It was planned to serve nearly 13 lakh residents across Chennai’s rapidly expanding southern suburbs, spanning from Sholinganallur to Thiruporur.  It also aims to capture surplus monsoon runoff, strengthen water security, and reduce seawater intrusion.

The reservoir was initially assessed at around ₹471 crore in the project’s environmental report, but the cost announced when construction was launched was ₹342.60 crore.

To now more about it : Read https://community.verified.realestate/article/a-%e2%82%b9471-crore-coastal-reservoir-near-kovalam-is-set-to-transform-chennais-southern-water-security/

The Tamil Nadu Water Resources Department divided the work into phases/packages and invited contractors through competitive tendering for this project.

For Phase 1, Package 1, covering the reservoir’s eastern and southern sides:

• Tender value was approximately ₹164.61 crore.
• The tender was published in November 2025.
• P&C Projects Pvt. Ltd. was subsequently awarded a contract reported at about ₹166.9 crore.
• The contractor was reportedly given 24 months to complete this package.

However, as the project has moved from proposal to execution, it has also drawn growing scrutiny from environmental groups, local residents and youth organisations. While the government presents the reservoir as a critical infrastructure project to address Chennai’s long-term drinking water needs, concerns have emerged over the ecological nature of the proposed site.

What is officially described as a development zone is, according to critics, part of a sensitive coastal landscape that plays a key role in the region’s natural drainage and biodiversity systems.

Protesters Say the Site Is a Living Wetland

The protesters argue that the project site is not vacant or unused land, but a functioning tidal marsh and coastal wetland ecosystem.

They fear that converting the brackish marsh into a freshwater reservoir would disturb the natural mixing of freshwater and seawater, affecting fish, prawns, crabs, birds and other species dependent on the wetland.

A fisherman from Kovalam said wetlands protect coastal communities and cities and should not be destroyed in the name of climate resilience.

Fishing Livelihoods Could Be Affected

The marshlands serve as fishing and breeding grounds for communities living around Kovalam and adjoining coastal villages.

Protesters warned that changes in water flow and salinity could reduce fish and prawn populations and threaten the livelihoods of fishing families. They also argued that Irulars, Dalits and other marginalised communities could bear the environmental and economic costs while the reservoir’s benefits are supplied to urban areas elsewhere.

Concerns Over Buckingham Canal and Flooding

One of the major allegations is that reservoir bunds and structures may obstruct the Buckingham Canal and natural coastal drainage routes.

Opponents fear that blocking or restricting these channels could increase waterlogging and flood risks during intense monsoon rainfall. They also warn that permanently converting a tidal marsh into an artificial freshwater storage area could cause irreversible ecological damage.

Protesters Demand an Independent Study

The youth organisations are not simply opposing additional drinking-water supply for Chennai. They want the government to prove that the project will not damage the wetland, increase flooding or destroy local livelihoods.

They have demanded an independent study covering:

• tidal and floodwater movement;
• impact on Buckingham Canal;
• fish-breeding and fishing areas;
• changes in salinity and groundwater;
• effects on birds and wetland biodiversity; and
• alternative locations or water-supply solutions.

The Mamallan Reservoir has now become an important environmental test for the present Tamil Nadu government. The central question is whether Chennai’s need for drinking water can be addressed without destroying a natural wetland that already provides flood protection, biodiversity and livelihoods to coastal communities.

Chennai is stepping into a major infrastructure upgrade with its Ring Main System (RMS) project. But instead of rushing into excavation, the Chennai Metropolitan Water Supply and Sewerage Board is taking a smarter route first.

Using Ground Penetrating Radar (GPR), officials will map everything beneath the city, including:

• Metro rail structures 🚇
• Stormwater drains 🌧️
• Electricity cables ⚡
• Telecom lines 📡
• Existing water and sewer pipelines 🚰

👉 Why this matters:
Unplanned digging can damage critical utilities, leading to flooding, power failures, or water supply disruption. This survey reduces those risks before construction begins.

🔁What Is the Ring Main System?

The Ring Main System is a loop-based water pipeline network designed to improve how water moves across Chennai.

Instead of water flowing in just one direction, this system allows it to circulate through multiple routes, ensuring:

• Equal distribution across all areas 💧
• Backup supply during failures 🔄
• Stable water pressure ⚙️
• Better handling of future demand 🏙️

The RMS is planned as a major Chennai-wide water grid project to improve uniform supply. It will interlink drinking water sources such as lakes and desalination plants through a ring pipeline.

🚰Understanding Feeder Mains – The Starting Point of Supply

A key component of this system is feeder mains.

👉 Feeder mains are large pipelines that carry treated water from treatment plants or reservoirs into the main city network.

Simple breakdown:

• Feeder mains = highways 🛣️
• Distribution pipes = streets 🏘️
• Your tap = destination 🚿

Without feeder mains, water cannot effectively enter and circulate within the network.

📏Project Size and Pipeline Details

This is one of Chennai’s largest water infrastructure projects. The project cost mentioned in the latest report is around ₹3,100 crore, with completion targeted before February 2030 and 10 years of operation and maintenance by the selected bidder.

Here’s the scale:

• 98 km Ring Main pipelines 🔁
• 115 km Transmission mains 🚰
• 16 km Feeder mains 🛣️

Reuse of existing infrastructure:

• 75% of feeder mains
• 7% of ring mains
• 44% of transmission mains

👉 This reduces cost and speeds up implementation.

🧩Three Implementation Packages – How the Project Is Being Built

Instead of executing the entire project as one contract, CMWSSB has divided it into three packages for faster and efficient execution.

Package 1 – Core Pipeline Network

• Construction of major Ring Main pipelines (98 km)
• Installation of key Transmission mains (115 km)
• Integration with existing pipelines

👉 This is the backbone of the entire system.

Package 2 – Feeder & Distribution Strengthening

• Development of 16 km feeder mains
• Strengthening existing pipelines
• Connecting water sources to the network

👉 This ensures water enters and flows efficiently into the system.

Package 3 – Integration, Monitoring & O&M

• System integration into a loop network
• Smart monitoring (like SCADA systems)
• Testing and commissioning
• 10-year operation and maintenance

👉 This makes the system reliable, flexible, and future-ready.

💰Who Is Funding This Project?

The project is supported by the Asian Development Bank.(ADB)

• ADB provides financial and technical support
• Government agencies like Chennai Metropolitan Water Supply and Sewerage Board (CMWSSB) execute the project
• Focus is on long-term infrastructure and sustainability

⚠️High-Risk Areas Identified

Certain zones need careful execution due to complex underground conditions:

• Velachery
• Madipakkam
• Sholinganallur
• Saidapet

These areas have:

• Dense utility networks
• High waterlogging risk
• Sensitive drainage systems

🏡What This Means for Chennai Residents

Once completed, the project can:

• Improve water availability 🚿
• Reduce sudden supply failures ⚠️
• Ensure balanced distribution across the city
• Support Chennai’s future growth 🏙️

However, during construction, residents may face:

• Road cuts 🚧
• Traffic diversions 🚦
• Temporary disruptions

🎯The Real Takeaway

This isn’t just about laying pipes.

Chennai is building a smart, loop-based water grid that can adapt, recover, and supply efficiently — even under pressure.

And the decision to start with underground mapping shows a clear shift:

👉 Plan first. Build right. Avoid chaos later.

Why Proper Maintenance Matters

Proper maintenance of vacant lands plays a vital role in:

• Urban Cleanliness: Keeping land free of waste and overgrowth enhances the city’s cleanliness.
• Public Health: Preventing mosquito and rodent breeding grounds ensures healthier communities.
• Safety: A well-maintained land is less prone to unauthorized use, illegal dumping, and encroachments.

Key Guidelines for Vacant Landowners

Here’s what landowners need to do to comply with the GCC guidelines:

1. Cleaning of Vacant Land
   • Regularly inspect the land for overgrown vegetation, waste accumulation, and stagnant water.
   • Remove weeds, bushes, and tall grasses to eliminate breeding grounds for pests.
   • Dispose of removed vegetation and waste in compliance with solid waste management rules.
2. Waste Management
   • Prevent the accumulation of solid waste and construction debris.
   • If any waste is found, remove it promptly, segregating recyclable and non-recyclable waste according to the Solid Waste Management Rules, 2016.
   • Do not burn waste, as it harms the environment and public health.
3. Drainage Maintenance & Water Stagnation
   • Regularly check for stagnant water and address water accumulation promptly to prevent mosquito breeding.
   • Ensure that drains and water channels are functioning properly and not blocked.
4. Fencing & Security
   • Install sturdy fences to prevent unauthorized access, illegal dumping, and encroachments.
   • Regularly inspect the fence for any damage and carry out timely repairs to maintain security.
5. Cooperation with GCC
   • Share your contact details and postal address with GCC’s Revenue, Health, and Zonal Offices for better coordination.
   • Cooperate with officials during inspections and promptly respond to any notices or requests from the GCC.

Compliance and Penalties

Landowners must comply with these guidelines to ensure the welfare of the community and prevent environmental degradation. Non-compliance may result in legal actions under the following provisions:

1. Warning Notice Procedure
   • If guidelines are violated, a Warning Notice will be issued, giving landowners 7 days to rectify the issues. Follow-up inspections will verify compliance.
2. Legal Provisions for Violations
   • TNULB Rules, 2023: Notices may be issued for mosquito/rodent control and waste removal. Failure to comply may lead to recovery of costs from the landowner.
   • TNULB Act, 1998: Penalties may be imposed for violations. A fine up to ₹25,000 may be levied, and continuing violations could result in an additional fine of ₹500 per day.
3. Waste Removal Charges
   • If waste is not cleared by the landowner and poses a public health risk, the Corporation will clear the waste and add the cost to the property tax under “Solid Waste Removal Charges.” The charges will be based on the amount of waste:
     • Up to 5 MT: ₹5,800
     • Up to 10 MT: ₹11,600

Conclusion

The Greater Chennai Corporation’s guidelines for vacant landowners aim to foster a cleaner, healthier, and safer urban environment. By ensuring proper maintenance of vacant lands, landowners can contribute to the city’s overall well-being, preventing public health risks and maintaining the aesthetic quality of the urban landscape.

The Issue with C&D Waste in Public Spaces

Currently, many residents and shop owners use construction debris, including broken bricks and mortar, to create temporary ramps connecting roads to their homes or businesses. While this may seem like a simple solution for accessibility, it has led to several environmental issues:

1. Dust Accumulation: The exposed construction materials contribute to increased dust in the area, which can be harmful to both human health and the environment.
2. Obstruction to Stormwater Flow: The accumulation of dust and debris in silt catch pits and stormwater chambers obstructs the smooth flow of rainwater, which can cause flooding and damage to public infrastructure.

Prohibited Practices and New Alternatives

To address these concerns, the GCC has outlined specific guidelines:

1. Ban on C&D Waste: The use of C&D waste and broken bricks for forming ramps leading from road margins and footpath edges to houses or shops will no longer be allowed.
2. Alternative Materials: Residents and business owners are encouraged to use alternative, non-polluting materials, such as wood or steel, to construct temporary ramps. These materials are more environmentally friendly and pose no risk to the stormwater infrastructure.
3. Safety and Maintenance: The newly proposed materials must be securely fixed in place to avoid any disruption to pedestrian movement. Additionally, the structures should be easily maintainable and not obstruct the cleaning or maintenance of stormwater systems.
4. Compliance Deadline: The GCC has set a deadline for compliance by June 30, 2025. After this date, enforcement actions will be taken under the C&D Waste Management Rules 2025 to ensure adherence to the new guidelines.

A Step Towards Sustainable Urban Development

This initiative is part of Greater Chennai Corporation’s broader efforts to enhance the city’s sustainability and reduce its environmental footprint. By eliminating the use of harmful construction waste in public spaces and promoting cleaner alternatives, GCC aims to create a safer, cleaner, and more efficient urban environment for its residents.

Conclusion

These new guidelines by the Greater Chennai Corporation are a crucial step in managing urban waste and improving infrastructure. Residents and business owners must act now to comply with these regulations and contribute to making Chennai a greener, more sustainable city.

A Local Area Plan is a strategic framework for guiding the planned and sustainable development of a specific area within a local authority. It outlines strategies for land use, infrastructure development, and overall growth.

The main idea is to create plans for Anna Salai and OMR, and the areas around them, so that there are a mix of homes, shops, and offices all in the same place. This means making busy, easy-to-get-to spots near where buses and trains are, with spaces enough to walk and cycle. This will hopefully make things healthier and better for the environment.

Specific Zones Under the LAP Initiative

The CMDA’s plan outlines the specific geographical areas that will be covered by the LAPs. For Anna Salai, the plan will address the 12.5-kilometer stretch extending from Omandurar Government Estate Junction to Kathipara Junction, with an influence zone of 500 meters on either side. Similarly, OMR will see a LAP developed for the 10-kilometer section between SRP Tools Junction and Shollinganallur, also encompassing a 500-meter radius on both sides.

Transit-Oriented Development as the Core Strategy

This project is a key element of the CMDA’s broader Transit Oriented Development (TOD) strategy. TOD aims to stimulate growth and development along Chennai’s major transportation routes, including roads, suburban trains, and the metro system. A significant aspect of the proposed TOD is an increase in the Floor Space Index (FSI) along these corridors. This will permit the construction of taller buildings, thereby increasing residential capacity and encouraging greater reliance on public transportation. For property owners and developers in these areas, understanding the implications of FSI is crucial, and services like Building Plan Approval offered by Verified.RealEstate can provide valuable assistance.

Why These Roads Are Important

The CMDA has highlighted the strategic importance of Anna Salai and OMR in Chennai’s socio-economic fabric. Anna Salai is a major commercial hub, encompassing key areas like Guindy, Saidapet, and Teynampet, and benefits from extensive bus and metro rail connectivity, including 10 metro stations. OMR, on the other hand, is the heart of Chennai’s IT and ITeS sector, featuring well-established residential and commercial areas such as Perungudi and Sholinganallur. While currently served by the MRTS for a portion, OMR is also slated for significant metro rail expansion with a 20-kilometer line and 19 stations planned from Nehru Nagar to Siruseri Sipcot. For those looking to invest in these dynamic areas, exploring property options through platforms like Verified.RealEstate’s Buy service can be a valuable step.

Community Input and Governmental Support

As part of the LAP preparation process, the CMDA will conduct household surveys in the affected localities to gather insights into the needs and aspirations of the residents. This participatory approach underscores the commitment to creating plans that are responsive to the community. Furthermore, the state government has already designated MRTS and suburban rail corridors as TOD zones, offering a 50% reduction in premium FSI charges. This policy support, building on a previous increase in base FSI in 2019, signals a clear direction towards higher-density development along transit lines. Future policy announcements are expected to extend TOD designation and potentially increase FSI along major roads and metro lines, making it essential for property stakeholders to stay informed about [Government Policies and Regulations].

CMDA’s Objectives for Anna Salai and OMR

The CMDA’s primary objective is to create more liveable spaces along Anna Salai and OMR by promoting integrated, mixed-use developments that are well-served by public transportation.

Action Plan Highlights

The core of the initiative is the implementation of the Transit Oriented Development (TOD) scheme along major roads. The LAPs will cover a 500-meter zone on both sides of the designated stretches of Anna Salai and OMR. Increasing the Floor Space Index (FSI) in these areas will facilitate the construction of taller buildings, accommodating more residents and encouraging the use of public transport.
