Comments:
Stormwater runoff from 17,000 square feet of the Barrington Square Apartment's rooftop is directed to a series of soakage trenches. Soakage trenches are shallow trenches lined with filter fabric and backfilled with stone, sand, or grass. They are appropriate in areas where native soils infiltrate well. Water enters the trench through a perforated pipe that allows water to slowly be absorbed by the underlying soil.

A circular driveway and a few parking spaces drain through curb cuts to this soakage trench. Soakage trenches can accept runoff from a variety of impervious surfaces and buildings.

Comments:
Dry wells are precast structures that collect stormwater runoff and infiltrate it into the ground. Drywells can be made from concrete, plastic, or other materials and come in a variety of widths and depths. Once these concrete drywells are place in a hole in the ground, they will be surrounded with open-graded aggregated. As water flows into the drywell, small holes in the side allow the water to infiltrate into the surrounding soil.
