Summary
After a presentation by public works and Jacobs Engineering, the council unanimously adopted the 2025 Water Master Plan, which projects demand through 2040 and recommends staged investments in supply, storage and treatment capacity.
Lake Havasu City Council unanimously adopted Resolution 26-3899 on Feb. 24, approving the 2025 Water Master Plan, an update to the city's 2019 plan that sets a planning horizon to 2040 and recommends a 10-year capital-improvement roadmap.
Public Works Deputy Director Tim Kellett introduced the plan and said the update aligns with recent wastewater planning work and looks at system performance, supply resiliency and forecasted growth through 2040. "This is an update to the 2019 water master plan, but, really, it's actually a fresh look at a water master plan," Kellett said.
Mark Elliott, principal engineer with Jacobs Engineering, reviewed system assets (more than 500 miles of pipeline, multiple pressure systems, booster stations and large supply wells) and said the water treatment plant is over 20 years old and will need upgrades in the coming decade. Elliott also presented supply flexibility options and a draft 10-year CIP. "The good news is you have another 5 to 10 years that you can just continue to monitor your treatment plant capacity," Elliott said, adding that supply-investment timing creates the peaks seen in the CIP timeline.
Councilmembers asked detailed questions about population assumptions, peak seasonal population and the modeling approach. Kellett said wastewater flow data were used to help estimate population dynamics and per-capita consumption, and the consultants modeled a range of growth and usage scenarios.
Vice Mayor David Diaz moved to adopt the resolution approving the water master plan; Councilmember Nancy Campbell seconded the motion and the council voted 6-0 to adopt the plan. Council directed staff to incorporate the plan's recommendations into annual CIP prioritization and to continue monitoring supply metrics tied to demand and regional allocation discussions.
The plan presents a phased investment recommendation for supply reliability, storage projects, pipeline renewal and treatment-plant improvements; the council will consider project-specific funding and timing during future budget cycles.
