[Case Study] MOUNTAIN REGIONAL WATER DISTRICT Deploys Next Generation On-Site Hypochlorite and Tank Mixing Technology to Meet Expanding Water Management Needs

The Mountain Regional Water District is a Special Service District of the county that was established by the Summit County Commission in 2000 to regionalize water service by consolidating several public and private water companies. Since its creation, numerous small water companies and developers have joined this regional public water company, helping to resolve water shortage and quality problems in Utah’s Snyderville Basin. Located in the heart of western Summit County, and in the second driest state in the nation, the District covers an area of 39.3 square miles surrounding the resort town of Park City, with a vast vertical extent ranging from 6,100 feet of elevation to nearly 9,500 feet, providing water to approximately 3,000 residential customers, over 300 commercial, industrial and institutional customers and more than 400 irrigation customer ERC’s, including 2 golf courses, and more than 30 recreation connections. The District remains not only committed to ensuring the quality of the water within their service area, but also takes conservation of its water resources seriously and continually makes efforts to improve the water treatment process and protect the environment.

This focus on technology, the environment, and sustainability was instrumental in the District’s award of an interest-free loan from the EPA and the state of Utah reserved for water entities that are actively developing “Green” water projects; meaning they can demonstrate a measurable reduction in energy, power, and other resources that can adversely impact the environment. Mountain Regional Water Special Service District turned to ProcessSolutions, Inc. (PSI), a UGSI Solutions company, in 2012 for cutting-edge process solutions to meet these objectives. The awarded funding was partially used to upgrade the chlorine generator (on-site liquid hypochlorite) at the District’s 4.5 million gallon per day membrane filtration Signal HillWater Treatment Plant (WTP) (also known as the Lost Creek Canyon WTP), significantly improving safety and operational efficiency. PSI’s Microclor®On- Site Hypochlorite Generation (OSHG) MC-100, which uses salt to make chlorine disinfectant with the addition of electrical power, was selected over all other options, including a direct replacement of the legacy OSHG system. The simple design and enhanced safety features of the Microclor®OSHG system’s modular design was attractive to the District. Their older, less efficient OSHG system had reached the end of its useful life and needed replacement. Ancillary components such as the brine and hypochlorite tanks as well as metering pump, however, were in a condition that did not require replacement.
