Valve for CSO applications

Red Valve’s Weirflex creates an adjustable weir for stormwater control in combined sewer systems. It is a variation on the company’s pinch valve principal: Instead of closing on centerline, the Weirflex closes from the bottom only to create a weir that can be used to retain stormwater in the sewer line. This allows the treatment plant operator to maximize existing stormwater storage within the lines while preventing the treatment plant from being over burdened by a stormwater surge. The Weirflex can be controlled remotely by an electric actuator or by a handwheel and bevel gear. Its open-frame construction provides a visual reference to valve position and weir height. It is available in sizes to 90’’.

Gutter guards

The Environmental Protection Agency has declared storm runoff the biggest threat to our water supply. Every year, millions of tons of pollutants — including trash and floatables — enter our rivers and lakes through unfiltered storm sewer systems. But storm sewer filtering is necessary, inexpensive and immediately available. Simple plastic guards from Heka Engineering can catch all large trash and water filters can sift out most of the sediment and much of the fluids.

Water quality vault

CrystalStream Technologies’ water quality vault works according to the fundamental principle that things less dense than water float and things more dense than water sink. Incoming stormwater flows through a fine mesh in the trash basket, capturing floating debris and vegetative matter. Water proceeds around baffles, slowing and spreading the flow and ensuring that oil gathers at the top. As the water level rises, the oil flows over the edge of the reservoir and the water flows under it to the outflow pipe. As the water rises out of the unit in the back chamber, it passes through a 3/4 inch coconut fiber filter designed to remove smaller floating or suspended materials. Other elements, such as absorbents, flocculants, or charcoal canisters, can be added to target specific pollutants.
