Bengal Mandates Wastewater Reuse in Housing
31 Jul
Summary
- Housing units must reuse treated wastewater for non-potable uses.
- 20% industrial water to come from wastewater by 2030.
- Policy promotes reuse in multi-storied buildings and public spaces.
The West Bengal state government has introduced the 'West Bengal State Policy on Safe Reuse of Treated Wastewater'. This policy directs residential housing units to maximize the reuse of treated wastewater for non-potable applications. It also sets a significant target for industrial water usage.
By 2030, the state aims to source at least 20% of the total statewide water requirement for industrial purposes from municipal wastewater. The policy encourages the adoption of treated wastewater reuse in various settings, including multi-storied buildings, gated communities, public structures, and commercial establishments.
Further, the policy emphasizes the creation of a comprehensive database and a GIS-based management information system. This system will facilitate regular assessments of water demand, wastewater generation, and reuse across different sectors, including mapping treatment plant needs and locations.
Technical surveys are advised for urban local bodies to understand current water resources and infrastructure. These bodies must develop urban water and wastewater management plans and establish treatment facilities. The state government will also coordinate with thermal power plants within a 50 km radius for wastewater offtake.
