Southwest Water Reclamation Facility


In 1999, the City recognized the need for a satellite facility to support the community’s increasing wastewater treatment and reclaimed water distribution demands in southwest Henderson. Currently, wastewater in the City is conveyed to the Water Reclamation Facility (WRF) at Pabco and Galleria for treatment. Then, the highly treated wastewater that is re-used to irrigate golf courses is pumped back across town. The addition of the Southwest Water Reclamation Facility (SWRF), located at Eastern and St. Rose, enables the City to treat wastewater in southwest Henderson and provide high quality re-use water to local customers without having to convey all the wastewater across town. 

Project Facts

Construction on the 20 acre site started in March 2008 and is currently over the 98% completion mark. Clean Water Testing, where the plant is put through its paces using potable water, is expected to commence this summer, with Dirty Water Testing to follow. We expect to be in full operations mode later this year. 

The project budget started at $92,900,000 and has experienced only a 1.62% increase due to change orders. The very low change order increase places the construction cost at $94,404,892.

The plant has a capacity of treating up to 8 million gallons per day (mgd) and will initially operate at about 4 mgd. 

Existing staff was augmented by four wastewater operators, an electrician, and a control systems technician in order to run the plant. 

The plant employs leading edge technology, including membrane bioreactors (MBR) and ultra-violet (UV) disinfection process to treat wastewater to some of the highest levels in the country.  MBR has an extremely small footprint and enables the City to minimize the quantity of chemicals used and stored on site. 

The plant is staffed for a single shift of the day and operators rely on Supervisory Control and Data Acquisition (SCADA) systems to control and monitor the processes. If any equipment or processes fall outside their expected parameters, SCADA notifies the operator on-call.

Berms surrounding the plant are 35 feet tall. The purpose of the berms is to help minimize the impact of the SWRF facilities on the neighboring communities. In keeping with the City’s efforts to encourage conservation, the berms are landscaped with xeriscape and native desert species. A neighborhood advisory committee was heavily involved in the design of the site. 

Almost everything is either underground or within an enclosed facility. This is to minimize any odors and noise. The plant also uses biofilters and granular activated carbon canisters to absorb any odors. While the canisters do need to be replaced over time, this technology doesn’t require the use of chemicals.

We are pleased to announce that start-up testing has begun, and the plant is expected to be treating all flows by the Spring.  At that time, the Department of Utility Services will be offering tours if you would like to learn more about the facility firsthand.
