Trap hydrocarbons and remove total suspended solids to improve stormwater quality

The ADS HDPE Water Quality Unit is your solution for trapping hydrocarbons and total suspended solids (TSS) from stormwater. Two weir plates act as trapping devices as the storm water flows through surface drainage structures and into the water quality unit. This structure also incorporates the use of a bypass system, which prevents re–suspension of captured solids by diverting water flows greater than 'first flush'.

ADS HDPE Water Quality Units are durable, lightweight structures specifically designed for fast installation and easy maintenance. Made from high–density polyethylene N–12® drainage pipe, these units are resistant to abrasives and chemicals typically found in storm water and surrounding soils. And when site conditions require higher levels of treatment, the ADS Water Quality Unit becomes an integral part of a multi–tiered approach known as the treatment train.

ADS HDPE Water Quality Units come in 16 standard models offering 36"-60" (900-1500 mm) diameters and 20' (6m) or 40' (12m) configurations, with longer lengths available upon request.
