The district is constructing an 11.5-mile, 36-inch diameter ductile iron water transmission line, known as the Sand Hollow Regional Pipeline, to provide culinary water to the southern areas of Washington and St. George. The approximately $16 million project, which started construction in 2019, will increase system efficiency and security and decrease treatment and pumping costs. Providing an independent loop to the system will also help protect water delivery in the event of an emergency or system maintenance or malfunction.
Water will come from the wells near Sand Hollow Reservoir, travel through Warner Valley and connect to the existing St. George and Washington municipal water systems. The pipeline is scheduled for completion in 2019.
As part of the pipeline project, the district will be constructing an off-highway vehicle (OHV) staging area at the north end of Warner Valley near the Southern Parkway underpass. The staging area will include parking, restrooms, campfire rings and an interpretive kiosk. Once constructed, the Bureau of Land Management will maintain the restrooms and facility. The staging area will be constructed in the late summer of 2019.
In addition to the pipeline, a five-million gallon concrete water storage tank will be constructed in Washington to allow for fluctuations in pumping capacity and area demands. The water tank will be added to the system in 2020.
