Relief valves
Norman Noe offers fire hydrant brass relief valves that are used to help relieve and adjust mains pressure when a water tank is off line for maintenance or during an emergency. The 2 ½" ASE valves are preset at 65 psi but can be adjusted from 0 to 120 psi. They are equipped with a pressure gauge and a fire hose adapter on the discharge end to help direct the discharge water.

Stormwater filtration
BaySaver Technologies has launched its new BayFilter stormwater filtration system. The multi-layered underground sand filtration system removes very fine sediment and nutrient pollutants from stormwater runoff at a flow rate of 30 gpm per cartridge. As stormwater makes its way through 43 square feet of surface area per cartridge, the filter removes more than 80% TSS (d50=23.2 microns) and greater than 50% of total phosphorous including dissolved phosphorus. It also boasts a 50% reduction of turbidity. The filter’s hydrodynamic backwash, self-cleansing component dislodges pollutants and restores the porosity of the media after every storm, contributing to efficient operation, extended maintenance intervals, and a long product lifespan.
