What Is a Catch Basin and Do You Need One?
A catch basin — also called a yard drain or surface drain — is a below-grade collection box with a grated surface opening that captures pooling water at the lowest points of your yard, driveway, or hardscape. The collected water is then routed through underground piping to a designated discharge point away from your property.
Catch basins are the right solution when water pools at a specific low point after rain — a corner of the yard that never dries out, a driveway that floods toward the garage, a patio that collects water against the house. Unlike French drains which address subsurface water, catch basins specifically target surface water accumulation.
Signs You Need a Catch Basin
- A specific area of your yard pools after every storm and takes days to drain
- Water collects on your driveway and flows toward the garage or foundation
- A patio or pool deck retains standing water after rain
- Lawn erosion channels have formed in the same low spot repeatedly
- Mosquitoes breeding in a chronic standing water area in the yard
- Water accumulates at a fence line from neighboring property runoff
How Catch Basin Installation Works
Our vetted contractors follow a precise installation process designed for Lowcountry soil and drainage conditions:
- Site assessment — identifying the exact low point, measuring flow volume, and locating a viable outlet
- Basin excavation — digging to the appropriate depth for the basin box and outlet pipe slope
- Basin and grate installation — heavy-duty polymer or cast iron basins with traffic-rated grates where needed
- Underground piping — smooth-wall PVC pipe run from the basin to the outlet at proper slope
- Outlet termination — daylight outlet, connection to storm drain, or dry creek bed depending on site conditions
- Backfill and restoration — tamped backfill and lawn restoration around the installation
