Strategic in-stream systems (STRAINS) are a decentralized approach to waste-water treatment to address the huge gap in waste-water treatment in Bengaluru. These are small-scale, low-tech, in-stream decontamination strategies to be deployed and monitored over the course of 1 year. The aim is to prevent the contamination and eutrophication of urban lakes. The design and building of the prototype at Saul kere lake Sarjapur is completed. Now it is time to check on its effect and teach residents how to monitor the system. The data will be available to the public through the citizen dashboard, developed by ATREE.
