This document summarizes a research paper on treating greywater using low-cost technologies for Kushvarta Kund water in Trimbakeshwar village, India. It discusses several low-cost treatment methods including stabilization tanks, root zone treatment, filtration, and biological treatments like membrane bioreactors and rotating biological contactors. A case study is proposed to implement and validate a stabilization tank system to treat greywater from the village and replenish the water levels at Kushvarta Kund, a historic stone-lined water tank visited by many pilgrims. Design plans and diagrams for the proposed stabilization tank treatment system are presented.
