APPROVE THE JULY 26, 2021, ENGINEERING AND OPERATIONS COMMITTEE MEETING
MINUTES
The minutes for July 26, 2021, were approved by unanimous roll call vote as submitted.
Managing Long-term Water Production
Mr. Milroy presented the District’s plan to secure long-term water production operations.
He explained that our partnerships with other local water agencies have been helpful in
this process. Following the completion of Sterling Natural Resources Center (SNRC) the
District will be recharging water in the Weaver basin. The State Water Resources Control
Board (SWRCB) provided the District with groundwater recharge requirements following
SNRC’s start-up. Due to their location, wells 143, 146 and 147 will need to be placed out of
service to comply with SWRCB. These wells provide 12 percent of the distribution to the
District’s customers, which will need to be replaced from other sources. Plants 120, 125
and plant 134 are good options for increased production to replace the 12 percent of water
that will be needed for distribution. The District secured Geoscience to assist with finding
the best options available and to provide insight for new water sources.

Minutes 5/24/2021 bvm
Mr. Milroy explained that staff has been working with consultants to evaluate and
implement rehabilitation and modifications to the distribution system and believe they have
a good plan in place.
Engineering Update for September 2021
Mr. Noelte reported on the progress at the Sterling Natural Resource Center. He displayed
exhibits that show the construction activities in the various locations throughout the site
and discussed how the site is progressing. Mr. Noelte explained the uses for the biogas
conditioning vessels, the bridge crane frame for the membrane facility, the biosolids
building, the ponds, and shared information about the areas outside the administration
buildings.
Mr. Noelte provided an update regarding the plant 134 Granular Activated Carbon (GAC)
project. The old Robert’s filter room will be cleared out to make room for the GAC vessels
as those filters were replaced by the membrane filters when the plant was upgraded. An
exhibit was presented that showed the configuration of the six GAC vessels.
Mr. Noelte provided an update on the construction progress of the battery installation at
the Headquarters and Plant 140. The system for Plant 134 is in the final stages of design.
The batteries can be charged when the kilowatt hours are cheaper, and that stored energy
can then help power the facility when the cost of kilowatt hours is higher. Also, the stored
energy can be used for backup power at these locations, reducing the need to run the diesel
generators.

TO: Committee Members
FROM: Operations Manager
SUBJECT: Operations Updates
RECOMMENDATION
This agenda item is for informational purposes only, no action required.
BACKGROUND / ANALYSIS
Updates are provided below for items that Operations staff are working on or have
completed.
North Fork Weir repairs:
During the 2021 North Fork annual meeting, staff committed to repairing or removing
old weirs from the North Fork ditch. Since East Valley Water District (EVWD) owns
99.87% of the shares, staff identified the weirs that are no longer needed.
Weir 2 was located north of District Headquarters in the orange groves where
the Mediterra Housing Project is in development. The developer completely
removed the weir at the beginning of the project.
Weir 3 is located west of weir 2 on the northwest portion of the Mediterra
project. This weir is scheduled to be removed and will require a few days of
construction. The 36-inch North Fork pipe requires excavation and then the weir
will then be cut out and new pipe will be installed. Staff will coordinate with a
contractor to complete this task towards the end of this year or beginning of
2022.
Weir 10, located on the Red Hill trail just south of Baseline and west of Alta Vista
and weir 18, located on the southeast corner of Baseline and Weaver are no
longer needed to make water deliveries. Staff determined these weirs are good
locations along the ditch to be used as an access point for inspections, so
upgrades were made rather than removal. Weir 10 was completed by staff and
weir 18 was completed by a contractor.
North Fork pipe repair at Santa Ana River:
The old 42-inch riveted steel North Fork pipe that crosses over the Santa Ana River
recently started leaking on top of the pipe. Because the pipe is suspended over the
Santa Ana River, cutting a portion of the pipe out was not our first option. Field crews
were able to fabricate and weld a steel plate on top of the main which completed the
repair.

Discussion Item
Plant 24 booster plant update:
Plant 24 booster station is an older plant in good running condition. However, due to
the age of the plant, cosmetic work was needed to be consistent with other EVWD
facilities. Production staff worked on this project a little each day, grinding and
removing old paint and painting again.
Photos of the various items described above are included in the attached presentation
listed under Exhibit 1.
AGENCY GOALS AND OBJECTIVES
