Points to be taken into consideration for implementation of the RWH structures:

  1. Valid where ground water level is more than 5 meter below ground level.
  2. Only the run-off water from the Parks and Garden area has to be diverted to recharge structure through channels.
  3. Before the onset of the monsoon, all the catchment area considered for recharge is to be cleaned.
  4. The recharge structures are to be in operation during the monsoon season only so as to avoid any contamination.
  5. The suitable type of first flushing device to be installed and initial 10 to 15 minutes of runoff should be diverted.
  6. The water collected from roof top only, should be stored in storage tank for direct use.
  7. The rain water collected from roof top should pass through suitable type of filter and only then it should be stored in storage tank / used for recharging ground water aquifers.
  8. Based on site condition length and breadth of the recharge structure may be altered keepings its volumetric capacity of the same.
  9. RCC slab thickness and reinforcement shall be dependent on structural loads. Access manhole frame and covers to be provided.
  10. Filter media of 1.0 meter thick will be in three layers comprising of 0.3 meter thick layer of boulders (5-20cm) at the bottom, 0.3 meter thick layer of gravels (5-10mm) in the middle and 0.3 meter thick layer of coarse sand (1.5-2.0mm) at the top so that the silt content that will come with runoff will be deposited on the top and can easily be removed.
  11. Recharge chambers shall be checked and cleaned at 7 days interval or more frequently during rainy season.

 

The harvested rain water may contain some toxic substances which may affect our health. The water collected from roof top after filtration can be used directly for lawn watering, washing etc. But if this water has to be used directly for drinking purpose, then quality of water must be ascertained before use.
