CONTECH Solutions for Subsurface Infiltration

Many urban developments have limited space for bioretention facilities, even when soils have high infiltration rates. For sites with limited area at the surface, and for sites with less than ideal soils, subsurface infiltration is the best option.  By utilizing sub-surface infiltration, space is preserved for development and runoff is reduced or eliminated, and groundwater recharge can occur. Best practice designs for subsurface infiltration include pretreatment to reduce cost and frequency of maintenance while ensuring and increasing the infiltration life of the facility.

Perforated Pipe Perforated pipe provides a large storage capacity in a small foot print and allows for exfiltration into surrounding soil.	ChamberMaxx Chambers provide storage capacity in shallow footprint, and the open-bottom plastic retention system allows exfiltration into surrounding soil	DryWell StormFilter Provide treatment and infiltration in one structure with a very small footprint. Easily adapts to multiple drainages for a modular design.
