Dry Creek Ranch is a planned community located northeast of Eagle, Idaho, between Broken Horn Road and Idaho State Highway 55. The community will encompass 1,414 acres and will include 4,300 single-family residences, parks, schools, and commercial and mixed-use areas when completed. Full site development will be in multiple phases, with the first phase encompassing approximately 268 acres and 557 residences. WATER Engineering was tasked with the design of water and wastewater facilities, and piping networks to serve the first phase of development and to accommodate future development of the full site. Designs were completed in collaboration with Instrumental Engineering who focused on structural and geotechnical aspects.

WATER Engineering’s designs addressed water distribution facilities to satisfy residential, commercial and fire suppression demands, including the design of water storage reservoirs and pump stations. Wastewater components of the project included the design of a collection system, treatment facility and final disposal of treated wastewater. An irrigation distribution system will supply parks and institutional areas utilizing treated wastewater effluent. WATER Engineering designed piping networks and facilities for the first phase with sufficient capacity to accommodate full site development.
