UrbanGreen Rainwater Harvesting Flexible Runoff Reduction Solution The UrbanGreen Rainwater Harvesting System is a single source solution that contains all of the components needed for stormwater re-use: a pretreatment device, a DuroMaxx Steel Reinforced Polyethylene (SRPE) cistern, and mechanical Rainwater Harvesting pump and filter system. The UrbanGreen Rainwater Harvesting system will help achieve stormwater management goals by reducing stormwater runoff while providing residual cost savings through the reduction of potable water use. A "Green Infrastructure" solution Stormwater runoff...

Corrugated Metal Pipe (CMP) Stormwater Detention and Infiltration Contech’s CMP stormwater detention and infiltration systems store stormwater exceeding a site’s allowable discharge rate and release it slowly over time. Systems can be sized and shaped to meet site-specific needs, and are available fully or partially perforated. CMP detention and infiltration systems have a minimum of 75-year service Subsurface Infiltration life for most soil/water conditions and has a proven service life that exceed 100 years with proper specification that meets all AASHTO and ASTM pipe specifications....

ChamberMaxx® Infiltration System is installed at an Indiana Hospital ChamberMaxxx® Stormwater Chamber System The ChamberMaxx corrugated, open-bottom plastic infiltration chamber system allows you to meet stormwater runoff reduction requirements and maximize available land space by providing economic infiltration below grade. ChamberMaxx maximizes storage volume in a small footprint, and Subsurface Infiltration its low profile shape is ideal for sites with shallow footprints. Underneath parking lots for subsurface infiltration Below bioretention for enhanced infiltration on sites with...

A 60” diameter DuroMaxx® Detention System installed in Washington DuroMaxx® Detention and Infiltration Subsurface Infiltration DuroMaxx steel reinforced polyethylene (SRPE) pipe combines steel and polyethylene (PE) to make an exceptionally strong and durable pipe. DuroMaxx is unique as it has fewer joints to assemble on site, can be made watertight, and can be used in applications with corrosive soils. Available up to 120” diameter – utilizing larger diameters whenever possible reduces storage cost per gallon Joint tightness available for all applications - 30 psi welded coupler (WC), 15...
