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.

Tulsa sits along the Arkansas River on rolling terrain that's hillier than most of the state, with soil that shifts from river-bottom clay near downtown to shaley, rockier ground on the surrounding hills. That hillside grading means water moves fast off upper lots and concentrates in low points — the older neighborhoods of Brookside, Maple Ridge, and Swan Lake, built from the 1920s through the 1950s, were laid out before modern storm-sewer capacity was standard, and their combination of mature tree cover and aging drainage infrastructure means heavy rain backs up quickly. Tulsa's proximity to the river also means a higher water table in low-lying areas near the floodplain. Green Country's humid subtropical climate brings frequent heavy thunderstorm cells off the Gulf, and the hill-to-hollow terrain around Tulsa concentrates that runoff into specific yards and basements rather than spreading it evenly the way flatter Oklahoma City does.

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.
