Maintenance- 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
