WRCRWA Construction Update: Digester Coating, April 2017 


Development to the expansion of the Western Riverside County Regional Wastewater Authority (WRCRWA) is moving forward as crews are nearing completion of phase 1, which included priority components such as odor control elements. As part of the expansion process, certain facilities at the treatment plant must undergo a coating process. The coating is necessary to protect concrete and facilities that come into contact with wastewater and chemicals used in the treatment process.

Starting on Thursday, April 13 – 19, from 2:00pm to 10:30pm coating work for Digester No. 1 will take place. As a courtesy to the nearby community, crews will work diligently to ensure that noise and light disturbances are kept to a minimum.

All previously implemented noise-reducing measures will be in place. This includes no sandblasting during nighttime hours, no back-up sirens and quiet air compressors. Temporary generators will also be strategically placed to minimize the potential for residual noise. Also, materials will be staged inside the digester prior to nighttime work. Lighting will be directed away from the surrounding neighborhoods. All of these precautions are made necessary in order to reduce disturbances to the neighboring communities.

Once completed, the upgraded plant will provide the community with permanent odor control improvements. Currently, the overall completion is at about 90 percent. We are currently projecting overall completion in September 2017.

We encourage you to report concerns about noise and odors issues immediately. Callers will be asked a series of questions to aid in establishing the location of the disturbance. Our team will seek a solution and immediately address the concern, whenever possible.

Every call received, relating to odor complaints, is required to be forwarded to the Air Quality Management District and WRCWRA complies with this mandate.

To report, please contact us immediately at:

  • Daytime – Monday through Friday, 7 a.m. to 4 p.m. 789.5189
  • Outside working hours and weekends (24/7) 789.5109
