project, contaminant source investigation, compounds of emerging concerns, and
regulatory compliance tracking.
ITEM RECEIVED AS AN:
Information Item.
DEPARTMENT HEAD REPORTS:
None.
CLOSED SESSION:
None.
OTHER BUSINESS AND COMMUNICATIONS OR SUPPLEMENTAL AGENDA ITEMS, IF
ANY:
Director Tom Lindsey referenced Item Nos. 4 and 5, and asked General Manager Thompson
how staff determines which spare parts to keep on hand. Mr. Thompson advised that staff
takes into consideration the criticality of the piece of equipment, the lead time to obtain the
item, how long of an outage the system can handle, and the commonality of the part.
Vice Chair Ooten asked Mr. Thompson if the influent flow trend was decreasing. Mr.
Thompson advised that it has fluctuated, but he believes it has leveled out and that
conservation equals population growth. He also advised that we are seeing an increase in
solids, which will continue to grow.
Chair Burns inquired about the Deep-Well Injection and Super Critical Water Oxidization
(SCWO) equipment needs and implementation timeframe. Mr. Thompson advised that
Deep-Well Injection could change Plant No. 1 solids treatment centrifuge use, which is high
cost, high turnover, and hard on equipment. This will cause the need to adjust centrifuge
usage. Truck loading would decrease, reducing the need for spare parts. Mr. Thompson
provided an implementation timeline of 4 to 6 years minimum and advised that we are
scheduled to receive SCWO equipment this month.
BOARD OF DIRECTORS INITIATED ITEMS FOR A FUTURE MEETING:
None.
ADJOURNMENT:
Chair Burns declared the meeting adjourned at 5:58 p.m. to the next Regular Operations
Committee meeting to be held on Wednesday, October 1, 2025 at 5:00 p.m.
