Telangana lies in the area which is prone to droughts, but v were very lucky to hav above normal monsoon last 5 yrs. But what lies ahead for upcomng yrs is unknown.
I vl talk abt terrace rainwater harvesting as this is something we hav installed in my apartment 3 yrs ago.
CONTD..

Using the example of last 3 days, we got 13cm rain. 13cm × 3500sqft of terrace area = 42 thousand ltrs of fresh water which is huge.
We divert this water to underground sump and remaining excess into bore.

Considering avg 70cm rainfall for Hyderabad, for 14 families in my aptmt, this is enough additional water for 54 days. But for individual houses with small terrace, it can go to 8 months of excess water, which is surprisingly high.

I urge each one of you to think about this. It is not an expensive installation as well, and you can do your part to save water and protect environment.
