The Underground Modular Rainwater Storage System from WaterCache offers a versatile and scalable solution for on-site rainwater retention and reuse. Custom-assembled underground cisterns can be adapted to challenging site conditions and expanded to achieve large storage capacities. Available in multiple shapes and sizes, these tanks are engineered for durability and load-bearing installations beneath driveways, parking areas, or landscaped surfaces. Modular design allows flexible layout configurations and reduces shipping costs by optimizing space. While the system is not intended for internal cleaning, its design prioritizes high-quality inlet filtration to maintain water quality over time. In addition to water reuse applications, the system can serve as a stormwater detention solution when paired with a pervious liner at its base. This makes it a practical choice for green building initiatives, stormwater mitigation projects, and sustainable site planning in both residential and commercial developments.
