Stormwater & Sub-Surface Recharge Pit Systems
Engineered for maximum aquifer replenishment, filtration efficiency, fast water percolation, and structural durability.
Precast RCC Ring Recharge Pits
Heavy-duty perforated RCC ring structures for deep soil percolation and high-volume runoff injection.
Modular Polypropylene Eco-Crates
High void space modular matrix systems offering ultra-fast water absorption and heavy traffic load handling.
Integrated Silt & Debris Desilting Chambers
Advanced pre-filtration chambers to remove suspended silt, leaves, and sand before entering the recharge pit.
Dual Recharge Borehole Shafts
Deep aquifer recharge shafts integrated with percolation pits to bypass hard clay and impervious rock strata.
Geotextile Media Encased Recharge Pit
Non-woven geotextile membrane lining surrounding aggregate beds to eliminate soil ingress and long-term clogging.
CGWA Compliant Groundwater Recharge
Turnkey rainwater harvesting recharge systems designed in strict accordance with CGWA norms and statutory standards.
Recharge Pit Sizing & Siting Matrix
Select the optimum recharge pit dimensions based on catchment area, soil infiltration rate, and peak monsoon runoff intensity.
