Project Letter mailed to customers

This work to improve your water system is possible because of our Water Infrastructure and Conservation Adjustment (WICA) program.  WICA funds enable us to accelerate the replacement of aging water system infrastructure and sustain valuable water resources. These projects ensure you and future generations of customers will continue to experience high-quality, reliable water service.

During the project, we will also be replacing our portion of the water service line that runs from our water main toward the curb line.  It may be necessary to briefly interrupt your water service during that time.  We will notify you at least 24 hours in advance of planned interruptions to plan accordingly.  Most interruptions are brief, lasting less than a few hours. It is not necessary that anyone be present at the time of the replacement.

Please use caution in the construction work zone.  Our work will involve trenches that may be up to 6 feet deep.  Our contractor will take all required safety measures to ensure the work area is safe, including appropriate signs, barricades and traffic control.  At times traffic lanes may be restricted.  Restoration work, such as repaving of driveway aprons and restoration of grass along the curb line, will take place when the project is fully completed.  Due to seasonal constraints around paving and planting, the restoration work may take place several weeks after we have moved through your area.

Our team has adopted precautions to work safely during the pandemic.  If you see those on the job, we ask you to maintain a minimum distance of six feet.  This helps us protect the people who help ensure that clean, safe water reaches your tap 24 hours a day, 365 days a year. Additional information can be found at Specifics, including scheduled service interruptions, will be communicated by phone, text and e-mail messages.  You will only receive these notifications if we have your contact information.  Please visit to provide your contact information for future notifications.
