Using reclaimed water for non-potable purposes as a means of conserving potable water supplies is the most prevalent method of water reuse in the United States today. One of the significant challenges for water reclamation facilities is to keep up with the demands for safe, compliant chlorine (Cl2) treatment. One utility that is effectively meeting this challenge is Southern California’s Otay Water District.
Greenhouse Water Management Practices: Greenhouse Practices Increase Need for Water Treatment Equipment
Water recycling has become a popular trend in the agricultural industry—one that creates an opportunity for water treatment suppliers to assist growers with the specification, installation and maintenance of water treatment.
Off the coast of Washington, 32 families on Guemes Island were faced with an aging well that was drawing salt water into its system. Because groundwater is scarce on the island, residents had to rely on what little rain water soaks into the ground.
The process of reusing wastewater for sprinkling at the Sugar Hill Golf Course in Gwinnett County, Georgia, was time consuming, costly and problematic. An in-line ultraviolet disinfection unit installed at the treatment plant solved the problem.
Aquifer storage and recovery is becoming an important water supply management tool for maintaining or enhancing the water-bearing capacity of an aquifer.
Artificial Recharge Enhances Aquifer Capacity
Wastewater is being reclaimed for non-potable uses. The use of this water is alleviating water shormance of the valve.
In addition, buried manually-actuated valves are easier to design and install if the operating valve shaft is horizontal and the gearbox input shaft is oriented toward the ground surface.
One concern with orienting the valve shaft axis horizontally is hydrostatic torque. Hydrostatic torque is a sizable operating torque component on large valves.
