Creative Solution for Henderson’s Water Delivery

The city of Henderson, Nevada, requested that the Southern Nevada Water Authority provide an additional 6 mgd capacity at the North Rate of Flow Control Station (ROFCS) to serve a growing area of the city. The station controls and meters the rate that water is delivered from the transmission system. The North ROFCS is located in an established residential neighborhood with limited room for growth. Expansion would require replacement of the existing turnout pipeline or installation of a parallel pipeline in a narrow right-of-way shared with other utilities.

Stanley Consultants was retained by the Southern Nevada Water Authority to determine the best way to provide the additional capacity. Nine alternatives were developed and evaluated that addressed issues such as neighborhood impacts, utility conflict and relocations; utility services disruption, constructability, construction schedule, and cost. The alternative selected was a creative recommendation that avoided all of the expected impacts associated with an expansion by constructing a new 15 mgd facility (Magic ROFCS). This would add capacity and reliability, without the other negative impacts and at an estimated 25 percent lower construction cost, by connecting to nearby system transmission pipelines at a more accessible and less sensitive location. The second phase of the contract involved predesign and design of the new Magic ROFCS.
