RETENTION TANKS

Precast Retention Tanks are a key part of stormwater management systems in modern infrastructure. They are used to temporarily store excess rainwater or runoff, helping to prevent flooding, reduce strain on municipal sewer systems, and support environmental compliance. These tanks are made from high-strength precast concrete, which provides excellent durability, load-bearing performance, and a long service life.
Retention Tanks are typically installed underground and connected to a stormwater collection system. When it rains, water flows into the tank, where it is held temporarily and then slowly released into the drainage network, groundwater, or treatment system. This controlled discharge helps reduce peak flow rates, limits erosion, and prevents pollution from entering natural waterways.
These tanks are available in a range of sizes and configurations, depending on the volume of water to be managed and the site constraints. Small systems for residential or light commercial use may hold a few thousand gallons, while larger systems for industrial or municipal projects can exceed 100,000 gallons. Tanks can be round, rectangular, or modular in shape, and are often designed to be connected in series to expand capacity.
Similarly, "Rain Gardens" perform the same function.
