PRESENT: Directors: Goodrich, Coats ABSENT: None STAFF: Michael Moore, General Manager/CEO; Jeff Noelte, Director of Engineering and Operations: Patrick Milroy, Operations Manager; Rocky Welborn, Water Reclamation Manager; Jason Wolf, Senior Engineer; Brenda Van Meter, Administrative Assistant GUEST(s): None PUBLIC COMMENTS There being no written or verbal comments, the public participation section was closed. APPROVE THE JULY 25, 2022, ENGINEERING AND OPERATIONS COMMITTEE 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. P a g e | 2 Minutes 9/26/2022 bvm 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. ADJOURN The meeting adjourned at 3:22 p.m. Phillip R. Goodrich Ronald L. Coats Governing Board Member Governing Board Member Agenda Item #2 November 28, 20221 Meeting Date: November 28, 2022 Agenda Item #2 Informational Item 5 9 0 Regular Meeting TO: Committee Members FROM: Director of Engineering and Operations 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.

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.
