MEETING MINUTES
Director Coats motioned, Director Goodrich second that the minutes for July 25, 2022, be
approved as submitted.
ACCESORY DWELLING UNITS
Mr. Noelte provided information regarding Senate Bills SB9 and SB10 that deal with Accessory
Dwelling Units (ADU’s). He said that the intention of the two senate bills is to provide
additional housing units within California by overriding zoning codes and limiting a governing
agency’s ability to charge fees and conduct plan reviews. Since this legislation took place, the
District has experienced a large increase of water and sewer inquiries related to the ADUs.
Mr. Noelte explained that the dwellings are typically between 500 and 1200 square feet and
can be separate structures or part of an existing structure. It appears that most of these units
are being established by rental property owners, as opposed to owners that live on the
property. The dwellings are typically established using existing water and sewer
infrastructure, so no capacity fees are collected. At times a larger water meter may be
requested to meet specific project requirements, which results in capacity fees according to
meter size. The District is monitoring the ADU activity and will keep the Board of Directors
updated as more information becomes available on the potential impact of ADU’s on the
delivery of water and sewer service.

OPERATIONS UPDATES
Sewer Manhole Repairs on Bradford Avenue and Orchid Drive
Mr. Milroy provided information regarding sewer manhole repairs that took place on Bradford
Avenue and Orchid Drive. The work took approximately six hours to perform, and normal flow
was restored to the area the same day. This project was a direct result of the proactive
inspection program that allows the District to prevent catastrophic failure.
North Fork Update
Mr. Milroy presented a North Fork activity update. He stated that recent thunderstorms caused
the water from the Santa Ana River to become muddy and unusable as a source to run
through Plant 134 for treatment. Mr. Milroy stated that while the treatment plants are not
designed to treat large amounts of dirt and debris that the water could be used for
groundwater recharge. He said that the water typically clears up within a few days and can
then be run through Plant 134.
North Fork Water Deliveries
Mr. Milroy provided an update regarding the water delivery for North Fork Water Company
customers. He said that staff has installed pressurized water service lines and meters that
have replaced the weirs previously used for delivery.
Short-Term Trade Agreement with San Bernardino Valley Municipal Water District
Mr. Milroy discussed the short-term water agreement that was established with San
Bernardino Valley Municipal Water District (Valley District). He stated that Valley District
requested an arrangement due to low allocations of State Water. This agreement included
the District having water available to Valley District for distribution to its regional partners and
forgoing groundwater recharge. The District will send Santa Ana River water towards
Redlands and Bear Valley during the low availability of State water. The District will receive a
gallon-for gallon credit for future State water at a value of $125.80 per acre-foot.

SUBJECT: Advanced Metering Infrastructure Update
RECOMMENDATION
This agenda item is for informational purposes only, no action required.
BACKGROUND / ANALYSIS
The District began the Advanced Metering Infrastructure (AMI) program in 2017 to
improve customer service, conservation and billing accuracy. The District has completed
the AMI program in five (5) phases. The program included replacing existing domestic
water meters. Fire Service meters are still read in-person on a monthly basis.
A contractor completed the replacement of small meters, those below 2 inches in 2021.
The changeout of large diameter meters was accomplished by District staff
intermittently throughout all phases of the program. The District completed the transfer
to smart billing of AMI meter reads as each phase of the program was completed. Over
the past year, the District and customers have realized many benefits of the AMI
program including:
•Help reduce water waste
•Utilize newer technology for reading water usage
•Identification of leaks sooner, which reduces system water loss Improved
customer service and increased customer participation
•Extended life/use of meter
•Improved customer service and increased customer participation
•Help reduce greenhouse gas emissions through decreased vehicle miles and fuel
consumption
The attached presentation will provide an overview of the project, benefits realized,
and general information on the operation of the program.
AGENCY GOALS AND OBJECTIVES
III - Deliver Public Service With Purpose While Embracing Continuous Growth
B. Strive to Provide World Class Customer Relations
IV - Promote Planning, Maintenance and Preservation of District Resources

STAFF IMPACT -FIELD
•Approximately 21,500 meters in system are AMI
•3% -7% require staff to read in the field each month due to incomplete
data transfer from meter to network (3% was pre-project estimate)
•Previously, 3 FTE’s were needed to walk the 94-meter routes
•Reduced labor requirements allowed 2 FTE’s to be re-classified to other
field positions
•Reduced exposure to field hazards like snakes, spiders, bees, syringes,
car traffic, and heat
6
STAFF IMPACT –CUSTOMER SERVICE
•Additional data provides improved transparency which leads to greater
customer trust
•If read data is missed, the Meter Tech can visit the meter and download
the previous 90 days of data
•Leak Protocol is improved with some ability to provide alerts, as well as
provide more data to mitigate conflict
•Bill preparation is less complicated
•Most reads are less complicated to obtain (No longer need to send rep
out for every inquiry)
7
CUSTOMER IMPACT
•Customers have access to an AMI “Smart Meter Portal”; approximately
30% of users are utilizing this tool
•Option to activate “Leak Monitoring” function within portal
•Option to pay their bills online via portal
•Ability to access monthly, weekly, and daily usage data
•More confidence in the services provided due to more than 30 times more
data available; previously, only 12 data points, one for each monthly read
was available

Regular Meeting
TO: Committee Members
FROM: Director of Engineering and Operations
SUBJECT: Plant 108 Reservoir Rehabilitation Project Change Order No. 3
RECOMMENDATION
That the Engineering and Operations Committee recommend to the Board of Directors
to authorize the General Manager/CEO to approve the Change Order No. 3 to Crosno
Construction Inc. up to $370,000 for additional services needed for extensive structural
repairs to Plant 108 Reservoir.
BACKGROUND / ANALYSIS
A Task Order was authorized to Crosno Construction, Inc. (Contractor) in December
2020 to clean, recoat and repair the coating system for the Plant 108 Reservoir
(Project). In April 2021, the Contractor was authorized Change Order No. 1 to perform
additional sand blasting to better assess the condition of structural elements. The
Project was subsequently deferred due to the required repairs being more extensive
than originally anticipated. The Contractor agreed to defer the task order until a future
date with Change Order No. 2.
The Project was re-budgeted for fiscal year 2022-2023 for $1,200,000. The tank was
taken out of service and the Contractor re-initiated the Project on October 26, 2022.
Additional repair work is required to replace 26 deflected full-length rafters, 26 jack
rafters, and 52 lateral braces. The damage to the rafters is thought to have been
caused by movement from an earthquate. The cost of this additional work to extend the
useful life of the tank will be approximately $370,000.
The tank was taken off-line during the winter months when water demand is lower. The
structural repairs will be performed through mid-January, followed by sand blasting to
remove the old interior coating system through February. Re-coating activities will take
place in March and April, and the tank will be put back into service near the end of
April. Once rehabilitated, the tank will provide reliable water storage until the next
rehabilitation cycle in 15 to 20 years.
