WWTP Construction Update

Whats Happening at the WWTP

We would like a moment to let you know what’s been happening at the Wastewater Treatment Plant (WWTP). We are currently in the construction phase of our Ultraviolet (UV) Disinfection Upgrade Project.  When completed, tentatively scheduled for Fall 2023, our facility will utilize UV disinfection instead of the existing sodium hypochlorite disinfection (chlorine) system.  Additionally, modifications and supplementary equipment added through this project will increase control, ultimately improving overall operation processes at the WWTP.

Why are we making this update?  Our current disinfection system uses chlorine to treat wastewater which creates byproducts that have negative impacts on our environment, and we are always looking at eco-friendly alternative methods to put into place. The advanced disinfection technology that we are implementing uses electricity to achieve disinfection rather than harmful chemicals. Thanks to the installation of an eighteen-panel solar array at our facility, we are able to generate a significant portion of the electricity needed to operate the plant, including the energy to run the new disinfection system. As we move forward, we will continue to explore and expand our green energy opportunities and advancements in wastewater treatment technology to further reduce greenhouse gas emissions and our facility’s overall carbon footprint. 

To complete the project, the WWTP facility will switch sewage processing tanks and associated vessels twice throughout the timeline. When these transitions occur the tanks and vessels that are taken offline need to be cleaned and repaired, sometimes resulting in unpleasant odors. Weather conditions including warmer temperatures and still conditions can exacerbate the odor.  In addition to the warmer weather, dry conditions also contribute to odors during these transitions.  Unfortunately, these are the exact times that we want to open our windows and allow fresh air into our homes.  Controlling odors is one of the most important and challenging aspects of wastewater treatment.  Determining the cause can be time-consuming, complicated, and ever-changing with issues not typically being solved overnight.  Please know that WWTP staff and construction crews are taking the appropriate steps to keep odors at a minimum so that we can all enjoy being outside this time of year while we complete essential work that will improve the function of the plant for the community now and into the future.  

If you have any questions or comments about the project, please feel free to contact us. We sincerely apologize for any inconveniences the odors have caused during this project.  We appreciate your patience and look forward to rain in the forecast!
