Mylapore Chitrakulam - Infiltration Tunnel Drain

The sacred temple pond remained dry most of the year due to blocked drains and poor infiltration. Rainwater could not recharge the groundwater effectively. Infiltration tunnels and Eco Bloc tanks were installed with minimal surface disruption to improve percolation. The project has become a model for temple tank rejuvenation across Tamil Nadu.

Coastal Road Besant Nagar - Infiltration Tank

The Besant Nagar coastal stretch faces persistent challenges with saltwater intrusion, driven by its closeness to the shoreline and high groundwater extraction. Traditional recharge pits could not protect the aquifer, allowing the saline wedge to move inland. To counter this, a high-capacity recharge system using Eco Bloc tanks and multiple rainwater harvesting structures was created to push stormwater deep into the freshwater zone and support the adjoining stormwater drain. The intervention strengthened freshwater retention and helped stabilise groundwater conditions across the coastal belt.

Semmozhi Poonga, Coimbatore

The Semmozhi Poonga stretch in Coimbatore experienced frequent urban flooding during intense rainfall due to high surface runoff and a lack of effective infiltration spaces. The situation was further compounded by a consistently low groundwater table, which limited natural recharge and increased dependence on conventional drainage systems. This highlighted the need for a decentralized, infiltration-based solution integrated along the road network to manage runoff sustainably while improving groundwater levels.

Stormwater Management Using Eco-Bloc Tanks in Greater Chennai Corporation Grounds

Few key community sports hub in Chennai, suffered persistent waterlogging during Chennai’s monsoon cycles. Poor drainage combined with a rising water table left the space unusable for days, disrupting regular play and community activities.

Integrated Sponge Park Design for Sustainable Stormwater Management

As part of Chennai’s Sustainable Flood Management Plan, the Mathur Sponge Park project introduces a large-scale, nature-based stormwater management system integrated seamlessly within an active public playground. The project combines underground rainwater detention, infiltration tunnels, and surface-level recreational infrastructure to transform the site into a high-performance urban sponge.

Mullai Nagar Eco Bloc Sponge Park – Tambaram, Chennai

The Mullai Nagar Eco Bloc Sponge Park is a pioneering urban stormwater management project developed for the Tambaram City Municipal Corporation under the CSR initiative of Karur Vysya Bank. Designed and executed by Stone Hands Projects & Consultancy Pvt. Ltd., the project demonstrates how innovative underground stormwater infrastructure can coexist with vibrant public spaces. By integrating Eco Bloc stormwater storage, infiltration tunnels, rainwater harvesting structures, and landscaped recreational facilities, the Sponge Park effectively addresses urban flooding while enhancing groundwater recharge and creating a sustainable community space.
