Underground Water Detention

Engineered for Critical Infrastructure

Underground water detention systems are vital for controlling stormwater, mitigating flood risks, and maintaining environmental stability. At CAS, we design our equipment to meet the rigorous demands of such projects. Our machines are built with robust direct hydraulic drive floors, patented worm gear systems, and high-quality components that ensure every operation is carried out with utmost precision and durability—even in the most challenging, confined underground environments.

The FatBoy Advantage: Bulk Movement Meets Fine Control

For underground water detention projects, rapid yet precise material placement is essential. The FatBoy, a true dual-purpose work truck, offers the best of both worlds. Its zero-degree feed floor combined with a 32″ exposed feed area and innovative hydraulic controls delivers consistent, high-volume material offloading with pinpoint accuracy. This design not only facilitates bulk material movement but also allows for refined control when delicate placement is required to build or repair detention systems, ensuring optimal water retention and flow management.

The AT7 Edge: Navigating Confined Spaces with Unrivaled Agility

When working within the restricted dimensions typical of underground water detention sites, the CAS AT7 proves indispensable. With its compact 12-foot footprint and powerful 225hp Tier 4 CAT engine, the AT7 is engineered to maneuver through tight spaces effortlessly. Its fully remote-controlled operation, along with versatile steering options—including crab and four-way modes—ensures precise material placement at distances up to 150 feet. This level of control is critical for achieving the exact material distribution needed to secure the structural integrity of detention systems while avoiding overfilling or structural stress.
