Case Study Details

The Durham Wastewater Treatment Plant (WWTP) in Strafford County, New Hampshire underwent a critical drainage system upgrade to improve stormwater management and long-term stability behind reinforced concrete retaining walls. The project addressed rising concerns about hydrostatic pressure buildup and erosion at this vital public utility facility. To address these challenges, Environmental Partners Group, LLC and the Durham Public Works Department specified a maintainable drainage system that would function long-term with minimal disruption.

Products Used

• 16 units of JET Filter – JF4SS: 4″ Diameter Open End Maintainable Weep Hole Filter, featuring ASTM 316/316L Stainless Steel Housing and Mirafi® Filter-Weave FW 300 Geotextile Filter Media.

Solutions

Retaining walls at wastewater facilities face relentless exposure to: high water volumes from rain and runoff, backpressure from soil and saturated earth, structural degradation without water release systems. Without proper drainage: infrastructure lifespan shortens, repair costs escalate, water buildup leads to unsafe site conditions. JET Filter’s maintainable weep holes offer a cost-effective, durable, drainage upgrade for retaining structures engineered to withstand high-moisture, debris-laden environments like treatment plants and stormwater channels.
