The purpose of installing weep holes in a stormwater trapezoidal concrete lined channel is to relieve the hydrostatic water pressure that may settle or rest behind the wall panel.
The One-way backflow preventer is an ideal solution for this type of application to manage erosion control and drainage concerns. The JET Filter comes equipped with the highly rated TenCate Mirafi FW 300 series. This proven application provides long-term flow rates in dynamic and high gradient conditions. To ensure proper drainage relief, one of the key components to our JET Filter System is a removable inner filter cartridge that can be replaced or cleaned when needed. This simple step can be accomplished from the front side of the trapezoidal concrete lined panel structure without excavating soil material behind the wall to replace the erosion control fabric. No excavation Required!
The JET Filter backflow preventer check valve assembly extends the life of the stormwater channel by relieving water pressure. Allowing proper drainage will save time plus money on avoidable extensive repairs or replacement. The life expectancy of a spillway basin flood control channel can be increased simply by adding sufficient drainage. Dry soil may provide little stress on the concrete panels, however heavy soil without proper drainage may cause the concrete panels to buckle or separate the seams causing erosion concerns. This could mean extensive and expensive repairs will be required for the districts budget forecast.
Installing JET Filter One-way backflow preventer check valve units will prevent any additional water behind the spillway/basin structure and won’t allow any floating debris through the weep hole. To keep flood control channels from failing due to clogged weep holes and pressure fractures caused by hydrostatic water pressure, it is important to install a simple maintainable/cleanable weep hole system to release this pressure.
