The Utilities Department will conduct its annual sanitary sewer mainline cleaning starting June 30th. Crews will clean approximately 20 miles of sewer lines. Jetter trucks use a high-pressure hose to remove debris and buildup from the pipes. During this work, residents may experience noise, air bubbles in lower-level toilets, or occasional toilet splashing. To minimize any inconvenience, please keep the lids of lower-level toilets closed during this time.
