System design

Catchment, filtration, and recharge

Rooftop catchment piping feeds sediment filtration chambers before water reaches sub-surface recharge pits. Each layout is planned around the site, the roof area, and the groundwater recharge requirement.

Civil digging, pit construction, and piping are carried out together so the system drains correctly and stays accessible for maintenance.

Water control

Integrated water control works

Catchment balancing

Flow is balanced between catchment, storage, and recharge so the system performs predictably through the monsoon.

Filtration maintenance

Sediment chambers and filters are set up for straightforward cleaning and periodic servicing.

Drainage and overflow controls

Overflow drains and recharge wells are sized and placed to meet municipal groundwater recharge and conservation guidelines.
