The Double Filtration Rainwater Harvesting System uses two filtration stages to remove larger debris as well as finer suspended particles before water enters a storage tank or recharge structure.
This setup is ideal for locations where rooftop and surface runoff may carry leaves, dust, sand, silt, and organic matter during heavy rainfall.
By improving water quality before recharge or storage, the system helps protect tanks, recharge wells, borewell recharge lines, and connected plumbing from clogging.
Rainwater from roof or surface drains is collected and directed toward the filtration chamber.
Leaves, twigs, and larger particles are separated in the first filtration stage.
Fine dust, sand, and silt are removed through the second filtration layer.
Filtered water flows safely toward storage tanks, recharge wells, or recharge pits.
Double filtration uses two stages to remove both large debris and finer particles from rainwater before storage or recharge.
It is useful for apartments, commercial buildings, schools, factories, and large rooftops with higher runoff volume.
Yes, filtered water can be routed to storage tanks as well as recharge pits or recharge wells.
Yes, cleaner water reduces clogging and helps reduce maintenance of tanks, recharge structures, and pipe networks.
Yes, double filtration can often be added to existing rainwater harvesting layouts after a site check.
