7328 Influent Pump Electrical Improvements
Several major improvements completed in the Headworks area, which included replacing the
influent pumps' VFDs and upgrading the PLCs, adding Influent Pump No. 6 for reliability and
redundancy during peak wet weather events, evaluating implementation of "Smart Utility" and use
of "Big Data" as part of this project, and adding submersible sump pump and wet well isolation
gates for flooding protection. During construction, modifications to the wet weather bypass
structure were added to the project. The bypass structure now has improved capabilities during
peak or intense wet weather events.
100008 Laboratory Roof & Seismic Upgrades
The Laboratory roof and seismic improvements were made to meet the Damage Control
Performance Level set by Central San. Modifications and the new roof consisted of new lateral
bracing, new columns at existing brace locations and other modifications as needed, replacement
of the existing roof membrane with a roof system that is more suited for the building, relocating an
existing air-cooled unit in the office area, and replacement of the Laboratory flooring.
100009 Hearth Replacement
This project rebuilt brick and masonry in an existing multiple hearth furnace (MHF) in the Solids
Conditioning Building. Work included confined space entry, demolishing and rebuilding a hearth
within MHF No. 1, and other identified repairs.

8436 Pump Station Upgrades, Phase 1
This project included major renovation at the Orinda Crossroads, Flushkleen, and Moraga
Pumping Stations (PSs). Major elements completed were: adding grinder(s) at the Moraga
Pumping Station; constructing a surge tank and canopy at Orinda Crossroads PS; replacing wet
weather diesel engine driven pumps with electric motors at Moraga PS and Orinda Crossroads
PS; adding new backup generators and automatic transfer switch improvements at all three sites;
reconditioning or replacing pumps, valves, and gates; repairing/recoating piping and concrete;
replacing major electrical/controls, including Arc Flash Study recommendations; replacing worn
control panels and seismically bracing control panels and electrical cabinets; improving safety
devices such as replacement of gas detection systems and eye wash stations; coordinating with
the City of Orinda, Town of Moraga, and others; and updating PG&E services and service panels
for the increased electrical demand needed to safely operate the facilities.
8449 Collection System Modeling Support
The major elements included in the project: coordinating and updating the InfoWorks® model with
the Geographic Information System, considering expansion of the trunk sewer model into high
priority development areas where anticipated sewer capacity evaluations will be required,
identifying critical areas with model -predicted surcharge conditions, and installing remote level
monitors and/or flow monitoring equipment and rain gauges.

8253 COVID-19 Response
This project paid for office and outdoor improvements related to the Covid-19 pandemic from
2019-2022. Work included employee signage, modular furniture modifications, replacing furniture
in breakrooms and other locations, building outdoor facilities for staff, and other improvements
needed to comply with Covid guidelines during the pandemic.
