This plastic rainwater collection tank system combines modular polypropylene storage units with the civil and hydraulic components needed to collect roof or surface runoff for later non-potable use. It is intended for projects that want to reduce mains-water demand while managing stormwater below ground.

From Collection to Reuse
A complete reuse system normally includes catchment surfaces, conveyance, first-flush or pretreatment equipment, the underground modular tank, pump controls and a separate non-potable distribution line. The modules provide the storage volume; filtration and system controls must be selected around local water quality, end use and maintenance requirements.
Where the System Is Used
Stored rainwater can support landscape irrigation, cleaning, toilet flushing or other approved non-potable uses. The modular footprint suits buildings and landscaped sites where available underground space is irregular. It may also be designed for combined detention and reuse when an engineered outlet and operating volume are included.
Installation Principle
Prepare the excavation and structural base to the engineer’s design, assemble the interconnecting modules, then wrap the tank for its intended function. A permeable geotextile configuration supports infiltration; a sealed geomembrane configuration supports storage and reuse. Inlets, outlets, pretreatment, inspection access, ventilation, backfill and cover depth must be specified for the site.
