S Viswanath, Water & Urban Planning Expert, Director, Biome Environmental Solutions delivered WaterTalk 7 on The practice of Integrated Urban Water Management in Bengaluru on December 18, 2020.
“The Global Water Partnership defines Integrated Urban Water Management or IUWM as a mechanism that provides a framework for planning, designing and managing urban water systems. It is a flexible process that responds to change and enables stakeholders to predict the impacts of interventions,”he said.
IUWM is all about environmental, economic, social, technical and political aspects of water management. It brings together all forms of water in a city, including solid waste and enables better management of water quantity and quality. Thus, IUWM calls for the aligning and development of basin management and includes economic, social and environmental parameters. However, no Indian city has completely followed IUWM in its letter and spirit.
Sharing various examples, he said that urban water management requires not a ‘water supply’ institution but a ‘systems design thinking’ institution. He said that to manage urban water the lessons learned from Bangalore are to be water conscious, use water-efficient fixture – aerators, taps, showers, flushes, washing machines, dishwashers, use Xeriscape and watering during evenings for gardening as it is the most water-consuming activity, use eco-friendly soaps and detergents, eat locally grown food, be more energy-efficient because it saves water and last but not least meters and pricing conserves water the best.
