National Learning cum Exposure Visit Showcasing Best Practices of Used Water Management and Lakes Rejuvenation


Water Management (UWM) popularly known as wastewater management, is currently a national challenge if lenses of sustainability are put on. It becomes further diverse and complicated in urban spaces. Waterbodies – rivers, lakes, tanks, ponds etc. have always been an inalienable part of many of our cities. A critical component of the human ecosystem, they have not only been a source of drinking water, but have also acted as sponges to recharge groundwater, supported biodiversity, provided livelihoods and performed the role of carbon sinks. Increasing, uncontrolled and unplanned urbanization is driving many of these urban waterbodies towards extinction. Most waterbody rejuvenation programmes focus only on beautification – without exploring long-term solutions for revival and long-term effort to ensure sustainability.

However, in the recent times a shift is observed in understanding of decision makers and technical societies towards nature based and decentralized solutions for wastewater management and lake rejuvenation. Some states have adopted these measures in early phases and currently pioneering in the field. Bengaluru city in Karnataka is one such example where UWM and lake rejuvenation has been understood holistically and dynamically. Further, the city administration and civil societies are creating an enabling environment in saving, reusing and treating every drop of water whether it is wastewater or natural water.

In the above context Centre for Science and Environment, is organizing a National Learning cum Exposure Visit to Bengaluru for the officials of relevant departments from various state governments. The exposure visit is being organized in association with CDD India and Biome Environmental Solutions Pvt Ltd. The participants will be exposed to practices of Decentralized Wastewater Treatment Systems applied in Bengaluru at various scales. Participants will also visit to local lakes at Jakkur and Devanahalli in Bengaluru to understand lake though nature based processes.
