Water Reclamation

Reclaimed water is wastewater that has been cleaned and highly treated to a level that is safe for use in irrigation, industrial coolant, dust control or in water features. While not intended for drinking water, the water is proven safe for plants, and even human contact in irrigated areas like parks, playing fields, construction sites and golf courses. By using this water for irrigation, we can preserve and enhance our precious drinking water supply and our environment.

The City uses reclaimed water primarily as irrigation for golf courses, a cemetery, and Boulder Highway medians. Reclaimed water also supplies the nine ponds that support the Henderson Bird Viewing Preserve. The City annually reuses approximately 30% of our reclaimed water for these purposes.

Reclaimed water that is not used for the above purposes is returned to the Colorado River system and earns return flow credits. That means for every gallon of reclaimed water we return to the system, we are able to take an equal amount of drinking water back out for use by the Henderson community. Reclaimed water is an essential component to ensuring our community's future water resources.


Kurt R. Segler Water Reclamation Facility (WRF)

The Kurt R. Segler Water Reclamation Facility is the City's primary wastewater treatment plant. Originally constructed in 1994 and upgraded in 2008, the treatment capacity is 32 million gallons of wastewater per day.

The WRF activated sludge process provides biological treatment to remove organics, solids, ammonia, and phosphorus to very low levels. Tertiary treatment to remove remaining phosphorus with chemicals is available, followed by sand filtration. The primary disinfection for the WRF effluent is ultraviolet (UV) light with the capability for chlorination/dechlorination, which can be used to back up the UV system.

 

Peak Performance Platinum Award 2022 

The Kurt R. Segler Water Reclamation Facility (WRF) has earned NACWA’s (National Association of Clean Water Agencies)

Peak Performance Awards

 Peak Performance Platinum award for 18 consecutive years. The 2022 Peak Performance Awards reflect permit compliance for calendar year 2021.
 
Platinum Awards recognize 100% compliance with Clean Water Act (CWA) National Pollutant Discharge Elimination System (NPDES) permits over a consecutive five-year period. Facilities that maintain 100% compliance beyond the initial award are honored with Multi-Platinum Award status.


Southwest Water Reclamation Facility (SWRF)

The Southwest Water Reclamation Facility (SWRF) is the City's first satellite wastewater treatment facility, beginning operations in 2012. Located near Eastern and St. Rose, it enables the City to support the community’s increasing wastewater treatment and reclaimed water distribution demands. The SWRF has the capacity to treat up to 8 million gallons per day (mgd) with a current flow rate just over 4 mgd.

The SWRF treatment stages consist of a headworks to remove organics and solids, followed by an activated sludge process. A state-of-the-art membrane bioreactor provides separation and disinfection, producing a highly treated effluent. Finally, treated water is chlorinated and distributed to reclaimed customers in the southwest part of the City.
