Catch Basins & Channel Drains in Bethesda, MD

Catch Basins & Channel Drains for Bethesda Homes and Estates

Some water problems are on the surface, and they need a surface solution. A catch basin is a box set at a low point with a grate on top that collects water and sends it through solid pipe to a safe outlet. A channel drain, sometimes called a trench drain, is a long, narrow grated channel set across a driveway, patio edge or garage entry to intercept sheet flow before it reaches the house.

The key is setting the inlet at the true low point and giving it somewhere to go. Pros grade the surrounding surface so water reaches the grate, bed the basin on compacted stone, connect solid pipe with steady fall and end it at a daylight outlet, dry well or rain garden on your own property. Sumps in the basin trap leaves and grit so the pipe stays clear. Grates can be plain plastic, cast iron or decorative brass to match fine stonework.

In Bethesda, channel drains are common at the bottom of sloped driveways on lots off River Road and Bradley Boulevard, and at the edge of bluestone patios where the surface pitches toward the house. Catch basins solve low lawn pockets in older neighborhoods. Local providers integrate grates neatly into stone, brick or pavers.
