Nearly two decades have passed since the concept of a satellite water reclamation facility was proposed for the west side of the Las Vegas Valley (Valley). Developments in the Valley have undergone generations of change in this short time, and efforts to adapt the original designs suggested for the satellite plant have raised many challenges. While some design choices allow for enough flexibility to respond to changing conditions as the facilities mature, others may limit future options and contribute to costly limitations. Generally, it is accepted that reclaimed water systems have not provided a revenue stream that is capable of supporting the entire cost of the system. However, uncounted benefits or perhaps non-participating benefited stakeholders are often the reason the balance sheet does not operate in the black. This paper discusses the challenges associated with designing a system using monthly average demand data to operate a system dealing with minute by minute control needs, determining the efficiency and reduced maintenance effort with different delivery control valves, and dealing with reduced supply values and wet weather operation limitations. Includes figures.
