Rainwater harvesting has become an increasingly valuable strategy for reducing reliance on municipal water supplies, lowering utility costs, and supporting environmentally responsible water management. ModuTank’s rainwater harvesting tanks offer dependable above-ground storage engineered for both commercial and industrial applications. Built from modular, hot-dipped galvanized steel panels and paired with high-performance membrane liners — including NSF-61 potable water grade polyethylene, polypropylene, and XR-5/XR-3 geomembranes — our systems provide secure, long-life containment for collected rainwater. Their modular construction allows for rapid installation without excavation, making them ideal for both new projects and retrofits where traditional cisterns or underground tanks are impractical.
Rainwater Harvesting Tanks
Rainwater can serve many non-potable uses, from irrigation and wash-down operations to cooling tower makeup water and industrial process support. ModuTank systems can be configured in square, rectangular, or custom footprints to maximize available site space, even in densely built environments. Tanks can be equipped with custom inlet/outlet penetrations to connect seamlessly with gutter systems, filtration units, pumps, and reuse equipment provided by other manufacturers. This adaptability makes ModuTank an excellent option for warehouses, office campuses, schools, agricultural sites, manufacturing facilities, and commercial buildings seeking to capture and store rainwater reliably and efficiently.
As water demands evolve, ModuTank’s modular design allows tanks to be expanded, resized, or relocated without major construction — a key advantage over fixed concrete or welded systems. Capacities range from a few thousand gallons to several million, enabling organizations to implement rainwater harvesting at virtually any scale. Our membrane-lined tanks protect potable water quality and ensure leak-free containment, while the durability of galvanized steel panels ensures decades of performance in harsh climates. By integrating ModuTank’s rainwater harvesting solutions, businesses and facilities can significantly reduce their water footprint, improve resilience during drought conditions, and support long-term sustainability initiatives.
ModuTank’s rainwater harvesting tanks combine reliable engineering, fast installation, and exceptional flexibility to deliver a practical, cost-effective solution for capturing and reusing rainwater. Whether the goal is conservation, cost reduction, or environmental stewardship, our systems provide the dependable storage foundation needed for successful rainwater management.
