“City records indicate that both Lift Station #1 and #2 force mains were installed in 1975. Assuming a useful life of
75 ye ars for ductile iron pipe, both force mains will be due for replacement by 2050. However, coatings and
structural components will require routine maintenance to reach this estimated useful life. The assumed useful
life is an estimate used for planning purposes and may vary based on a variety of factors, therefore, the force
mains should be assessed in the next five years to confirm the need for, and timing of, maintenance, rehabilitation,
or replacement. This project will perform a comprehensive structural and condition evaluation of the Lift Station
#1 and #2 pipe bridges, abutments, and force mains. The evaluation will also include corrosion testing and non-
destructive wall thickness testing of force main coatings. This is anticipated for FY 2022-23.”

“With the recent upgrade to tertiary treatment at the wastewater treatment plant, the City is investigating
opportunities to increase inflow into the wastewater treatment plant (WWTP), in turn, increasing recycled water
production. The potential uses of the high-quality recycled water include groundwater recharge and irrigation for
facilities such as parks, vineyards, and golf courses. The City is envisioning diverted stormwater as a potentially
viable source for increasing WWTP inflow. This project entails the preparation of a Stormwater Diversion
Conceptual Design Report, building off the findings and preliminary siting identified in this Wastewater Collection
System Master Plan. The Stormwater Diversion Conceptual Design Report will include further investigation into
diversion infrastructure and siting, preparation of an alternative’s analysis, identification and evaluation of legal
and permitting constraints, and preparation of preliminary drawings and cost estimate for the recommended
alternative. The opinion of cost includes an allowance for preparation of an Initial Study for CEQA compliance but
may not include full scope for undefined supporting studies (biological, cultural, etc.). Follow on CEQA work, such
as a Mitigated Negative Declaration or Environmental Impact Report, are not included in this budget. The report
is anticipated for FY 2023-24.”

“Much of the infrastructure at Lift Station #2 was identified during the lift station inspection visit to be nearing the
end of its useful life. Among the deficiencies are significant corrosion of the discharge piping,
manifold, valves, and bypass piping; cracking of the wet well liner; lack of structural support in the wet well hatch;
corrosion of the site fencing; and distressed onsite pavement. This recommended CIP project is to replace Lift
Station #2, including, but not limited to, replacement of the valve vault, pumps, piping and valves, pump controls,
and level sensing systems, along with site improvements including pavement repairs and replacement of the
perimeter fencing. The wet well will be evaluated to determine if it should be rehabilitated or replaced. This is
anticipated for FY 2025-26.”
