A catch basin is a surface inlet — a grated box set flush with the grade — that collects standing water or runoff and routes it through underground pipe to a discharge point. They're particularly effective in low spots where water consistently pools and where a french drain alone won't work because there's no subsurface flow to intercept.

Altus sits in Jackson County in Southwest Oklahoma, near Altus Air Force Base, on flat, semi-arid terrain with soil that mixes red clay and sandier ground typical of the region's cotton and wheat farming history. Southwest Oklahoma's climate runs drier than the central and eastern parts of the state, with lower average annual rainfall but real exposure to intense, fast-moving storm systems that can drop heavy totals in a short period — conditions the area's flat, open grading wasn't built to handle regularly. Much of Altus's housing stock dates to the mid-1900s growth tied to the air base, with drainage infrastructure sized for the region's more typical dry conditions rather than its occasional severe-weather extremes, which is why an unusually heavy storm can leave standing water in Altus yards that stay bone-dry most of the year.

When a Catch Basin Is the Right Solution

Catch basins work best when water is collecting at the surface in a defined low point — such as the end of a driveway, a depression in the yard, or at the base of a slope. Unlike a french drain, which intercepts subsurface water as it moves through the soil, a catch basin captures water after it has already concentrated at the surface. They're often used in combination with french drains and underground pipe to create a complete drainage system.

Installation and Maintenance

The basin is set at grade level with adequate elevation to ensure water flows into it naturally, connected to underground PVC pipe, and routed to an appropriate outlet. Catch basins require periodic cleaning — leaves, silt, and debris collect in the basin over time and can reduce flow. You'll be shown how to maintain the basin after installation to keep it performing correctly.
