The decentralised wastewater treatment systems (DEWATS) approach is considered a cost-effective method of wastewater treatment in rural and semi-urban India. DEWATS in India face challenges over a time, as they are unable to meet the effluent standards. The lack of community participation and the delay in adoption of technology-specific regulations for maintenance are some of the challenges. According to the authors Dr. Somnath Pal and Ms. Charu Bhanot, Research Associates, TERI, the decentralised wastewater treatment and reuse system may acquire popularity with the right mix of higher water charges, tougher enforcement, and incentives for early adopters.

There is a need for India to undertake planned efforts to address climate change mitigation and adaptation. Improving water-use efficiency, strengthening early water-warning systems with precision for flood forecast, adopting climate-proofing of cities and resilience measures, increasing groundwater storage, well-managed effluents and other wastewater should be initiated as major steps. Groundwater has to be used in a sustainable way, writes Dr Syamal Kumar Sarkar, Distinguished Fellow & Senior Director, Water Resources Division, TERI.

Despite significant achievements, more needs to be done for the complete eradication of fecal pollution. The ongoing SBM programme can be strengthened further if the effect on groundwater quality and human health conditions are quantified and used for policy decisions. Climate-resilient sanitation technologies need to be developed so that septic tanks and sewerage systems are not affected by frequent floods, which helps in protecting the groundwater aquifers, writes Mr Syamal Kumar Sarkar, Distinguished Fellow & Senior Director, Water Resources Division, TERI.
