21 Water Tower Maintenance and Inspection. Shown below is a routine list of items to be completed at each water tower. • Daily inspection of telemetry readings (tower levels). Intrusion alarms on tower entry doors are also monitored. • Grounds maintenance, mowing, trimming, tree trimming and snow plowing. • Repairs and painting are needed to the wood fence at the North Tower. This will be coordinated with the Cell Provider per the lease agreement. • Current guidelines recommend a full inspection (float down inspection) of the tower structure, coatings, and OSHA safety requirements every 5 years. This includes draining the tower to roughly 50% and completing a thorough inspection of the wet area. The remainder of the tower, referred to as the dry area is also inspected. Both our towers are with steel, corrosion is a large concern. Correcting the coating/ paint early prevents costly future repairs. o The North Tower repainting project, final warranty repairs were completed in 2021. The next float down inspection is expected in 2026. o The evaluation completed by BSI for the South Water Tower was review and recommendations were presented to Council for spot paint repairs and security additions. PW staff will coordinate as needed with a contractor on this project. Water Distribution Repairs and Restoration to be complete at the following locations- • Harriet Ave (approx. 50’ west of east Benton Way access) – restoration of a 10’ x 10’ asphalt patch. • 4421 Arden View Ct – Small asphalt patch and soft scape restoration. • 1134 Hunters Ct - Restoration will include a 10’x20’ asphalt patch. • Harriet Ave (approx. 200’ west of the east Benton Way access) – This restoration will be larger due to the severity of the water leak. We will replace asphalt from the curb to centerline by 20’ long. Gate Valve Exercising to be completed on valves that were installed in 2003 and newer. The process of gate valve exercising is important for the overall functionality of our water distribution system. PW staff ensures that the valve box is clean of debris, accessible to operate and the valve fully opens and closes without leaking. Operating the valve also removes deposits that build up along the gate guides. Exercising valves is a proactive method to ensure the valves will function properly when needed during emergency watermain repairs. • Update current gate valve history map, last update was done in 2013. Emergency Water Distribution System Repairs are not something we schedule, but it’s important to note in the annual work plan. In 2022 PW staff responded to 9 emergency repairs and 3 repairs that were able to be scheduled shortly after identifying the problem. Excavations uses staff time both before and after the actual repair. Many factors are taken into consideration such as- assessing public safety, property loss, staffing, equipment needs, time of day, weather conditions, property owner needs, and public notification.
