Water scarcity is a critical challenge in Tamil Nadu, intensified by rapid urbanization and rising residential demand. Sustainable water management and innovative technologies are not just goals but necessities. At Conserve Consultants, we emphasize the Net Zero Water approach ensuring that water consumption is balanced with natural replenishment, which empowers residential developments to become water-resilient and environmentally responsible.
Understanding Net Zero Water and Its Importance
Net Zero Water means achieving balance between water consumed and water replenished onsite through strategies like rainwater harvesting, wastewater recycling, and reduction of water demand via efficiency measures. This principle ensures minimal strain on municipal water sources and mitigates water scarcity risks.
Water Demand & Stress in Tamil Nadu
Domestic water consumption in key urban centers like Chennai accounts for about 20-25% of local demand, projected to rise sharply by 2050. Existing water supplies and infrastructure are under pressure due to climate change and population growth, necessitating immediate action towards water-smart designs.
Conserve Consultants’ Approach to Sustainable Water Management
Our multifaceted strategy includes:
- Adoption of efficient fittings and fixtures
- Rainwater harvesting systems
- Advanced Sewage Treatment Plants (STP) for water reuse
- Smart meters and leak detection technology
- Landscape design with native plants to minimize irrigation needs
Project Showcase: Radiance Regalia, Coimbatore
Radiance Regalia stands as a benchmark IGBC Net Zero Water design project. Key highlights include:
- Built-up area: 32,843 sqm housing 125 residential units
- Implementation of STP with 120 KLD capacity for water reuse in flushing and gardening
- Rainwater recharge contributing over 16,600 KL annually
- Achieved Water Performance Ratio of 0.56 and Water Back to Source ratio of 1.02, confirming net zero water balance
This exemplifies how combining technological integration with sustainable design can achieve water neutrality without compromising quality of life or project economics.
Project Showcase: Navins Anthiea Poetry, Bangalore
Navins Anthiea Poetry is another exemplary project certified under IGBC Green Homes, demonstrating significant strides towards net-zero water management:
- Usage of rainwater harvesting and wastewater treatment for non-potable applications
- Water meters installed for effective consumption monitoring
- Landscape using native flora and efficient irrigation
These measures collectively support water conservation and reduce freshwater withdrawals in an urban high-rise setting.
Financial and Environmental Benefits
Green building projects with Net Zero Water certification yield tangible advantages:
- Reduction in water bills due to lesser municipal water use
- Mitigation of risk linked to water scarcity and regulation changes
- Enhanced market value and reputation among eco-conscious buyers
Contribution to local ecosystem conservation and climate resilience
