REGIONAL WASTEWATER CONTROL FACILITY (RWCF)
STOCKTON, CA
In September of 2019, WML work began on the Stockton RWCF
Modifications Project. This $215M Progressive Design-Build
project is a joint-venture with our design partner, AECOM. The
major components include construction of new influent pumping,
screening, and grit removal systems, new secondary biological
treatment systems, new tertiary filtration and disinfection systems,
new solids handling facilities to replace an existing oxidation pond and
overland flow treatment system, and new laboratory, Administration,
Operations and Maintenance Buildings. Major process equipment will
include large vertical turbine solids handling pumps, perforated fine
screens, conical tray grit removal systems, primary and secondary
clarifier mechanisms, aeration blowers and diffusers, submersible
mixers, tertiary disc filters, UV disinfection system, sludge centrifuge,
associated electrical, control, and SCADA upgrades. The project is
about 75% complete, and we’ve placed over 35,000 CY of concrete,
installed about three miles of pipe, and performed 180,000 CY of
earthwork. Currently, the project has achieved a significant milestone
with the Start-up and commissioning of the Secondary Treatment
processes, including the New Aeration Basins, four (4 each) 165’
Diameter Secondary Clarifiers, and a RAS Pump Station. Structural
work for the new Influent Pump Station and Grit Facility is approximately
90% complete, and Construction of the new Final Effluent Pump
Station is underway. The new personnel buildings are nearing
completion, and we are targeting the end of the year for occupancy by
City staff. This project has been a massive undertaking by all parties
involved and an example of what is achievable when everyone has
a commitment and dedication to teamwork and a common goal.

HIGHLANDS ARD (4/5) SEWER RELIEF PROJECT
North Highlands, CA. The Highlands Sewer Relief Project is
a multi-phase project upgrading sewer facilities in the North
Highlands area. W. M. Lyles Co. (WML) has the contract for
Phase II of the project which includes construction of a new
pump station, decommissioning of two existing pump stations,
and site improvements.
After an initial delay to the start of the project, work began on
the new S016 pump station in August 2022. This is a challenging
project with deep excavations for two new manholes, clay pipe,
and a 12-foot diameter by 38-foot deep wet well on a very small
site sandwiched between two houses on a residential street.
WML will also construct an Electrical building, a cast-in-place
10
8
valve vault, and install pipe and valves that will connect to the
new force main installed during Phase I of the project. Once the
new pump station is commissioned both the S016 and S015
pump station, which are located a few miles down the road, can
be decommissioned.
Our crew, led by Brodey Thorn and Reid Snyder, have met this
challenging project head-on and have completed the installation
of both manholes and are currently setting up to install a bypass
to facilitate connection of the new 30” gravity pipe to the existing
sewer system. We will then move on to the large excavation for
the wet well. This project has a completion date of October 2023.
