A rainwater recycling system captures runoff, removes debris, stores the treated flow and supplies it for approved non-potable uses. These interconnecting PP modules form the underground storage section, allowing the tank volume and shape to suit the catchment, demand and available site footprint.

From Collection to Reuse
The storage modules are one part of the complete recycling process. Roof or surface runoff first passes through suitable pretreatment and filtration before entering the sealed tank. A pump and dedicated non-potable distribution line can then supply irrigation, toilet flushing, site cleaning or other uses permitted by local regulations. Overflow control protects the system during larger storms.
Design Priorities
For reuse projects, capacity should be based on catchment yield, daily demand, seasonal rainfall and the acceptable backup-water frequency. Water quality treatment depends on the source and intended use. The civil and structural design must also address excavation conditions, burial depth, surface loading, backfill, inspection access and maintenance.

Installation Overview
Prepare the base, assemble the interconnecting modules and wrap the structure with a sealed geomembrane. Fit the specified inlet, outlet, overflow, ventilation and inspection points before backfilling. Pretreatment should be accessible for routine cleaning, and pumps and controls should be selected for the required flow and delivery pressure.
