FAQ
What is a water audit in Kaushal Bodh Chapter 5?
A systematic accounting of how much water enters a home, school or community, how it is used, where it is wasted, and how consumption can be reduced or recycled.
How does a reed-bed system clean grey water?
Grey water settles in a sedimentation tank and then passes through the root zone of water-loving plants like Canna indica and Colocasia, which absorb organic pollutants.
