In India, only 58% of households have access to piped water in the dwelling and the government predicts that annual average water availability per capita will decline 13% between 2011 and 2025. The ongoing water crisis, compounded by rapid population growth and competing water uses, would benefit from water efficiency.

CLASP and local partner Environmental Design Solutions investigated the viability of water efficiency policies in conserving water and mitigating associated carbon emissions from water heating. A draft national policy under development with the Bureau of Indian Standards could avoid 71 MT of CO₂ emissions and reduce water consumption by 7 trillion liters annually.
