CONSIDER APPROVAL OF THE MARCH 27, 2023, ENGINEERING AND OPERATIONS
COMMITTEE MEETING MINUTES
Directors Goodrich and Morales recommended that the minutes be approved as submitted.
PLANT 108 RESERVOIR REHABILITATION PROJECT UPDATE
Mr. Carlson provided an overview and update of the Plant 108 Reservoir Rehabilitation Project.
The scope of the rehabilitation included replacement of rafters, coating the interior of the
tank, and modifications to comply with current OSHA standards.
Information only.
GROUNDWATER LEVELS
Mr. Drury provided a presentation regarding groundwater levels and discussed how this
year’s rainfall has affected the levels. He explained the process of how 15 active and 13
inactive wells are measured and stated that the well measurements are tracked monthly
and charted for District reference. Groundwater levels take years to increase, but the recent
rainy weather is a step in the right direction for improving groundwater levels.

SUMMER READINESS
Mr. Milroy presented the District’s Summer Readiness plan. He explained that when the
Sterling Natural Resource Center goes on-line, the District will not operate four wells. The
Production department has been actively pursuing the best options to ensure water reliability.
He highlighted an increased production at treatment plant 134; the addition of a pressure-
reducing valve at Plant 129 to drop water from the Foothill Zone to the Upper Zone; bringing
Plant 120 back into service; researching interconnections with the City of San Bernardino;
running the wells during Southern California Edison’s (SCE) peak hours. He explained that
running the wells during SCE’s peak hours is more expensive but may be necessary to ensure
water reliability during the hot summer months. Mr. Milroy stated that the summer demands
are not expected to result in any emergency actions.
Information only.
UPDATES
Mr. Noelte stated that the recycled water pipeline construction is approaching Weaver Basins.
He also reported that Engineering is working on a predesign report for reservoirs at a District-
owned property near the north end of Church Street.
Mr. Milroy reported that the Operations department has been working on start up for the
generator at Plant 101. He also stated that new membranes for one train will be installed at
Plant 134 provided they are approved in the next budget year.

Agenda Item #2
Informational Item
Regular Meeting
TO: Committee Members
FROM: Water Reclamation Manager
SUBJECT: Sterling Natural Resource Center Biosolids Residual Management
RECOMMENDATION
This agenda item is for informational purposes only, no action is required.
BACKGROUND / ANALYSIS
Treatment processes at Sterling Natural Resource Center (SNRC) will result in a residual
solid material referred to as biosolids that require management in accordance with
State and Federal regulations. In 2022, the Board approved an agreement with Rialto
Bioenergy Facility, LLC for the hauling and advanced treatment of biosolids generated
at SNRC. Staff is evaluating lower-cost alternatives for biosolids management that are
based on conventional treatment processes.
Regulatory requirements for the processing, disposal, and reuse of biosolids are
extensive. These regulations may be revised in the future to potentially address
polyfluoralkyl substances (PFAS) and other emerging constituents of concern that
naturally concentrate in biosolids.
A slide presentation has been developed to provide perspective on solids encountered
in wastewater treatment, the purpose of biosolids treatment processes, regulatory
requirements, available options for management, and the District’s planned approach
for biosolids management at SNRC.
AGENCY GOALS AND OBJECTIVES
I - Implement Effective Solutions Through Visionary Leadership
A. Identify Opportunities to Optimize Natural Resources
IV - Promote Planning, Maintenance and Preservation of District Resources
A. Develop Projects and Programs to Ensure Safe and Reliable Services

•Digestion
•Biological Stabilization
•Reduce pathogens found in wastewater and concentrated in wastewater solids
•Produce Methane/Energy Generation
•Decaying organic material results in methane rich gas for combustion
•Volume Reduction
•Volatile Solids Destruction results in less volume of solids for hauling
•Odor Reduction
•Digested sludge releases less odors than raw sludge
•Dewatering
•Volume and Weight Reduction
•Separating water from solids reduces weight and volume of solids for hauling
