What We Do

Rainwater Harvesting Solutions

End-to-end RWH systems for buildings, campuses, and industrial sites.

Rooftop Collection Systems

Design and installation of rooftop catchment systems with gutters, downpipes, first-flush diverters, and conveyance channels — maximising rooftop runoff capture.

Rooftop CatchmentFirst-Flush DiverterConveyance Design

Surface Runoff Capture

Surface drainage design and permeable pavement systems to capture and direct site runoff to storage or recharge structures — maximising catchment area beyond rooftops.

Filtration Systems

Multi-stage filtration — coarse screens, sand filters, and activated carbon units — ensuring harvested water meets quality standards for the intended end use.
