The following steps should be adopted to ensure quality of harvested rain water:
|
Keep all catchments neat and clean
|
|
|
Don’t allow contaminated water to flow into system
|
|
|
Put iron/nylon mesh/fine cloth on inlet and outlet pipes and chambers to prevent solid debris from getting into the system
|
|
|
Clean open drains regularly by removing deposits of sand and gravel
|
|
|
Make available a layer of soil beneath the recharge structure to ensure natural filtration
|
|
|
Drain and clean storage tanks thoroughly before every monsoon
|
|
|
Change the filter media every year
|
|
|
Remove algae from the roof tiles and asbestos sheets before the monsoon
|
|

Do not let water stagnate in the collection chamber since this will slow down the recharge of water
|
|
|
Repair cracks in ferrocement tanks
