PRESENT: Directors: Goodrich, Morales ABSENT: Patrick Milroy, Operations Manager STAFF: Michael Moore, General Manage/CEO; Jeff Noelte, Director of Engineering and Operations: Rocky Welborn, Water Reclamation Manager; John Drury, Water Production Supervisor; Brenda Van Meter, Senior Administrative Assistant GUEST(s): Wayne Brown; Jason Wolf; Brandon Lopez PUBLIC COMMENTS There being no written or verbal comments, the public participation section was closed. CONSIDER APPROVAL OF THE JULY 25, 2023, ENGINEERING AND OPERATIONS COMMITTEE MEETING MINUTES Directors Goodrich and Morales recommended that the minutes be approved as submitted. PLANT 134 UPDATE Mr. Drury provided an update regarding Plant 134 upgrades and improvements. He presented information that detailed how the plant treats water and noted that we are in the fifth year of the District’s membrane replacement plan. Mr. Drury talked about the addition of Granular Activated Carbon (GAC) to the plant and provided a chart that showed the improvement in water quality since GAC was added. He reviewed the upgrade to the Eaton strainers and noted that the new screens are larger, allowing the plant to achieve better water filtration. The membrane treatment in coordination with the GAC treatment has improved the water quality. Mr. Drury discussed Plant 134’s capabilities to produce water and said that the plant currently produces about 20% of the water distributed to the District. He stated that the plant has the potential to produce up to 50% of the water for the District. The Production staff tested Plant 134’s production capabilities during the summer and were able to produce 6.5 Million Gallons of water per day. Plant 134 has the potential to make up to 8 Million Gallons of water per day. Mr. Drury presented photos showing the muddy water being released from the Seven Oaks Dam that resulted from hurricane Hillary. He said that this water was not usable due to the amount of mud and debris present in the water. P a g e | 2 Minutes 09/25/2023 bvm 9 1 2 Plant 134 typically runs 24/7 and requires consistent power. Tesla batteries were recently installed to ensure consistent power to the plant. Information only. Engineering Activities Mr. Noelte presented an Engineering update that included the installation of the Tesla batteries at Plant 134. He stated that the batteries have been placed in the retaining wall structure and the conduit from the battery area to the Southern California Edison meter has been installed. Engineering is currently working with the City of Highland on final coordination of the upcoming recycled water pipe construction at the City Creek bridge crossing. Mr. Noelte stated that the work for this project will require around the clock work for approximately four weeks. He reported that during pipe installation, the pipe is split into smaller pipes that are then threaded through the bridge and connect on the opposite side. Work on this project is expected to begin Monday, October 2, 2023. Information only. Operations Update Mr. Welborn provided an Operations update. He reviewed the Conservation District’s activity related to groundwater recharge and its project to construct improvements to the Mill Creek spreading basins. Conservation District staff have been asked to provide an overview and update to the Engineering & Operations Committee at its November meeting. ADJOURN The meeting adjourned at 2:39 p.m. Phillip R. Goodrich James Morales Governing Board Member Governing Board Member Partnering with Nature to Store Our Water Mission As one of California’s first sustainable groundwater replenishment agencies, the District proactively recharges and improves groundwater for the benefit of water users, local businesses, and native flora and fauna in a financially responsible way. The District leverages our unparalleled expertise as stewards of the water and land, responsibly innovating in water and habitat conservation, harmonizing and enhancing working landscapes, and enriching open space as a community asset.

We are stewards of the San Bernardino Valley water basin and the native species of the wash above it. We protect the land that cradles our region’s water by being proudly scrappy and fearlessly creative. We take a fiscally prudent, pragmatic approach towards fulfilling our mission to that the water supply and the environment it depends upon will be forever protected and available for the community’s use.
