United Water Idaho plans to complete four major projects, totaling $4.6 million, to improve water service and fire-protection in north and east Boise’s hilly areas.
The company is installing 24-inch main line along Hill Road. Owyhee Construction last year finished the first phase, from Harrison Boulevard to 26th Street, will continue to 36th, United Water Idaho spokesman Mark Snider said. The project is designed to improve fire-protection capacity, water pressure and water quality for customers north of Hill Road and in the 36th Street area, he said. It will cost about $1.96 million to complete.
Plans to rebuild and expand a booster station on Good Street, east of 15th Street and north of Camel’s Back Park is in design phase. The $800,000 project is designed to improve water pressure and fire-protection flow in the Boise Foothills area, Snider said. No service disruption is expected because the existing station will be kept in operation until the new station is completed, he said.
The Boulder Reservoir, in service more than 40 years on the Warm Springs Mesa in east Boise, will be replaced. United Water will install a smaller tank at East Boulder Creek Drive and South Trent Point Way in the northeast section of the mesa.
“There should not be any interruption of service,” Snider said. “But if everybody decides to run sprinklers at the same time on a summer day, there could be pressure issues.”
McAlvain Construction will install auxiliary power generators to the Warm Springs and Toluka booster stations as part of the $800,000 Boulder Reservoir project to start this month.
“In the event of a power outage, we’re still able to pump water up the hill to fill the reservoir,” Snider said.
A million dollars has been budgeted to replace water mains – nearly 30,000-lineal-feet – in north Boise. United Water is replacing galvanized iron, 2-inch diameter and smaller mains with polyvinyl pipe with twice the diameter. A large portion of the main was installed after World War II. Owyhee Construction plans to start the project in the spring.
“In a lot of cases, the 2-inch mains are undersized and have water-quality issues,” Snider said.
Much of this work in the past two years was centered on the Boise Central Bench.
