Reclaim Valuable Land and Water Resources


PIPE-R™ Reservoir System is a subsurface retention/detention system that takes the place of conventional above ground systems. PIPE-R™ is constructed of 4-inch corrugated HDPE pipes. The pipes are banded together to form cubes (modules) that are placed adjacent to one another to provide storage volume and structural integrity. The system offers designers a solution for challenging project conditions such as limited available space, budget constraints, and seasonal high groundwater table. ECS engineers will provide an initial system layout in AutoCAD to meet the site-specific requirements provided by a design engineer.
