Coyote Springs is a master-planned golf community in golf-happy southern Nevada. The development's 43,000 acres include a Jack Nicklaus course and thousands of housing units just 50 miles northwest of Las Vegas. Coyote Springs is the largest single private land holding in the region. When it's built out, the development could be home to as many as 200,000 people.
Water is also in demand but, in the dry Desert Southwest, more difficult to find than developable space. To provide water enough for hundreds of thousands in the parched desert, Pardee Homes of Nevada – the primary home builder for Coyote Springs – needed a water campus.
Pardee Homes turned to HDR Design-Build, which completed the facility plan and was assigned duties for a water treatment facility and two wastewater treatment facilities. The project for the 20,000 housing units on 6,200 acres is the first teaming of Pardee Homes and HDR.
The first wastewater treatment facility, with a capacity of 0.10 million-gallons-per-day (mgd), was designed for temporary use. The second is a permanent facility with an initial capacity of 2.1 mgd. This facility has coarse screens, influent pumping, grit removal, fine screens, screenings and grit washing, flow equalization, nitrification and denitrification, activated sludge, membrane bioreactors, disinfection with sodium hypochlorite and sludge dewatering with belt filter presses.
One hundred percent of the effluent is proposed to be reused on up to 15 golf courses and open space. This water campus is among first pieces in a development that could have 19 phases and 30 mgd of water and wastewater treatment capacity.
