Catch Basin: A catch basin is a drain with 4 walls and a solid floor. The purpose is for sand, dirt and other sediments to sink to the bottom. Any oil, gasoline, or other hazardous liquids will stay at the top of the tank, and using a T pipe only clean water will flow through a pipe leading to a drywell and drain into the earth.

Drywells: A dry well is another form of drain and unlike the catch basin it has 4 walks and an open floor. It is laid on a bed of compacted crushed gravel so water can go into the earth. Most drywells residential driveway drains are between 300-1000 gallons of capacity. In heavy rains, the flow of water into a drain may be faster than the rate at which the ground can absorb. Which is why we do drainage calculation of your driveway and possibly any roof water to be sure the open space inside the drain can handle heavy rainfall without overflowing.

Trench Drain /Line Drain / Poly Drain: In its simplest form, a trench drain provides an elongated surface for water to drain from a specific area, such as a driveway, beneath an un-guttered roof edge, sidewalk, or similar area where water tends to collect. It’s essentially a gutter that is set into the ground.
