Water Authority - Regular Meeting · 2026-07-22 · agenda_item

The Lake County Water Authority is reviewing plans for regional water supply and water quality improvements. This review involves assessing projected population growth and its impact on water demand across different planning regions, including north and south Lake County. The process includes identifying potential water resource constraints and soliciting projects to meet future needs. These projects could involve alternative water sources, aquifer recharge, wellfield management, and water conservation efforts. The scope of work will likely involve studies, planning, and the implementation of various water management and infrastructure projects. Contractors, suppliers, and service providers in areas such as engineering, environmental consulting, construction, and water resource management are encouraged to engage early to understand the evolving needs and potential opportunities before formal bidding processes begin.
