No public comments.
4. Items for Committee Recommendation to Board
a. Review draft Position Paper authorizing the General Manager to:
1. Execute a purchase agreement in an amount not to exceed $5.5
million with Trojan Technologies Group ULC for ultraviolet (UV)
disinfection equipment and special services for the UV Disinfection
Replacement, District Project 100012 and
2. Amend an existing professional engineering services agreement with
Carollo Engineers, Inc. in an amount not to exceed $4.4 million
increasing the cost ceiling to $5.3 million for final design services
Mr. Lopez provided a detailed overview of the presentation included in the
agenda materials.
Chair Pilecki asked what the capacity limitations were of the primary,
secondary and pond systems during events. Mr. Lopez responded saying
that the primary capacity is between 160-170 million gallons per day
(MGD), and the secondary capacity max is around 100 (pushed at times
to 110 MGD) due to UV capacity, and the pond had about 10 MGD
capacity remaining. Engineering believes that another day or two of
receiving flow at that magnitude would have overwhelmed the holding
ponds and other facilities. Operations prefers to run UV disinfection closer
to 90 MGD since the process is very stable at that flow. Anything above
that can stress the process. Further discussion continued.
Chair Pilecki asked if there was a limitation on the permit for average day
or peak day flow. Mr. Lopez responded saying that staff would look into
the permit limitations, however the flows received during the events
shouldn't impact the permitted avg limits.
Mr. Lopez mentioned that the new UV system would be 50 percent more
energy efficient at normal flows, and that maintenance costs, parts and
equipment, as well as staff time would also decrease.
Member McGill asked if there was a price guarantee, such as for bulbs.
Mr. Lopez responded that all the guaranteed costs will be included in
future maintenance contracts.
Member McGill commented that a contingency of five percent seemed low
and asked if the District has a clause in the agreement for escalation.

Mr. Lopez explained the five percent contingency is only for equipment
and design. The construction contingency will most likely be higher.
When taking this item to the full Board, Chair Pilecki requested staff
include the original projected cost of$68 million in the presentation table,
so the other Board Members are aware of the size of the project.
COMMITTEE ACTION: Recommended Board approval.
5. Other Items
a. Receive update on Fiscal Year 2022-23 Mid-Year Capital
Improvement Budget
Mr. Lopez presented the Mid-Year Capital Improvement Budget update for
