| 2) | Annual and Daily Rainfall for a Block / Taluk / District is the average for the region |
| 3) | Rainfall grater then 2mm per day is considered for calculations |
| 4) | Actual rainwater collection is assumed at 75% of potential by considering runoff co-efficient, first flush, filter efficiency etc. |
| 5) | Pipe sizes for rainwater collection from the roof are considered as per Indian building code |
| 6) | RWH tank suggested is around 1/10th the volume of annual rainwater potential from the given roof |
| 7) | Ground water recharge well / pit volume considered is 1/3rd of RWH tank size suggested |
| 8) | Tank / sump dimensions suggested are inner sizes and are excluding the wall / roof / floor thickness |
| 9) | Roof water filters to be installed (size / numbers) according to the design details of particular brand / model of filters |
| 10) | It is advisable to test periodically the quality of rainwater collected before using / recharging to the ground |
