Urban Water Management Challenges and Solutions
Current Water Supply Situation
The city relies heavily on the Cauvery river, which provides 80% of its piped water supply. This water is pumped over 100 kilometres against a steep elevation, making it one of the most energy-intensive urban water systems globally.
Future Water Demand and Crisis
- By 2030, water demand is expected to double the current available supply.
- The need to transition from supply-side augmentation to efficiency-led water management is critical.
- Urban centres like Bengaluru highlight the severity of the water crisis.
- Studies show over 85% of Bengaluru's lakes are eutrophic, impairing biodiversity and groundwater recharge.
Challenges in Urban Water Governance
- Increasing dependence on unsustainable water sources.
- Structural vulnerabilities in urban water governance across India.
Efficient Water Management Strategies
- Adjustment in plumbing systems and consumption habits can save significant water volumes.
- Examples include reducing water usage in flush tanks and converting grey water to purified drinking water like the ITC Hotels' Zero Mile Water initiative.
- Implementing smart plumbing systems with sensors and aerators can enhance water conservation.
Industry Insights
The plumbing industry in India is valued at ₹5 lakh crore annually, with a growth rate of 20% CAGR.
Water sustainability is now a critical issue for India's ecological and developmental future.
Upcoming Initiatives
The Indian Plumbing Association will host PlumbexIndia 2026 from April 16 to 18 to focus on water sustainability and urban water challenges.
