System Overview
Configurations and Technical Data

The STORMTREAT SYSTEM's design accomodates varying site configurations and allows installation in many areas where standard techniques, such as detention ponds simply will not fit.

The STORMTREAT SYSTEM is constructed of recycled polyethylene.

Sizing

The STORMTREAT SYSTEM is sized based upon the water quality design storm, the area of impervious surface, the amount of water processed during the storm and the available volume of preliminary detention. Generally 1-2 units per acre of impervious surface are required to meet standards. To calculate the number of units and detention volume best suited for your application, download the StormTreat Sizing Calculator (STSSizingCalculator.xls) file below.

The STORMTREAT SYSTEM

The STORMTREAT SYSTEM incorporates effective pre-treatment by directing stormwater through STORMTREAT'S unique, multi-stage, total suspended solids (TSS) removal system prior to infiltration. This includes: 1) a series of sedimentation chambers fitted with "skimmers" which significantly enhance the settling efficiency of particultates by continually drawing from just below the surface of the water and "decanting" it to the next chamber, 2) a gravel filter which serves as a substrate for 3) a constructed wetland. Larger-diameter particulates are trapped inside the sedimentation chambers and smaller (silt and clay-sized) particles are filtered in the gravel wetland substrate. The smaller particles are predominantly organic in composition and therefore can be decomposed in the wetland soils by bacteria which reside within the wetland plant root zone.

Treated stormwater can then be infiltrated into the 3/4-inch stone used for backfill in the excavation around and under the STORMTREAT tanks. This stone is highly permeable and serves to transmit the treated water downward until it encounters the parent soils. During peak flow periods, the infiltration rate may exceed the permeability of the parent soils and the stone backfill area serves as a temporary storage reservoir. As this area fills with water, a substantially larger leaching surface is encountered by the treated stormwater.  ----
