2. Call Meeting to Order
Chair Nejedly called the meeting to order at 2:00 p.m.
3. Public Comments - No public comments.
4. Agenda Items
a. Receive update and status of preliminary findings regarding the Steam
and Aeration Systems Renovations, District Project 7349
Mr. Petit provided a brief overview of the project and the multiple tasks
that encompass the project scope. As shown on slide 4, the Condition
Assessment task is furthest along since great strides were made when
inspections occurred as portions of the plant were taken out of service.
Mr. Goel continued with the presentation. He explained that comprehensive
assessments were studied to determine the estimated remaining useful life
of the assets and a color-coded system was created (slide 7).
From an aging asset perspective, the assessments showed that most of
the steam system equipment is in the green category (remaining useful life
of 20-plus years). The electrical assets had different findings, mainly due
to age. As shown on slide 13, some of the transformers are coded orange
(or nearing replacement within 5-10 years). These transformers were
installed in the 1970s and, with the diligence of the Maintenance group,
the transformers have remained operational and useful life remains after
many years of service. It was added that the MCCs (motor control centers)
are challenging to take offline and further evaluation will need to continue.
Member Pilecki praised the condition assessment work, stating it is
information he wants to know and see in order to make decisions. He
added that this information provides him with the understanding of what
needs to be done and when.
Chair Nejedly commented that these assessments are time-consuming
and costly, and that onsite staff is already aware of the condition of
equipment. He opined that a lot of time and money is spent talking about
these matters rather than fixing the problems. Critical components should
be monitored and fixed as required, preferably long before they fail;
information that staff working on the equipment should already know. He
stated he does not want to see the District doing study after study with
multiple consultants when staff is well versed on these matters.
COMMITTEE ACTION: Received the information and provided input
to staff.

b. Receive report on Fiscal Year 2019-20 Closeout of Capital Improvement
Projects
Mr. Lopez reviewed the materials included with the agenda packet. In a
recap of the total expenditures of these closed projects, he noted that this
year he added a new underrun/overrun column as compared to the budget.
Overall, for sixteen capital projects closed this fiscal year, the aggregate
underrun was more than $824,000. He continued with an overview of the
slides of individual projects that were over$1 million.
Member Pilecki asked whether the replacement of the Solids Conditioning
Building roof was coordinated with the upcoming Solids Handling Facility
Improvements project (Solids Handling). Mr. Lopez replied that some of
the walls will be modified during the Solids Handling construction that may
impact the roof; however, the new membrane type roof can be easily
repaired. He added that although the new roof may be touched in some
areas during the Solids Handling project, the roof replacement could not
wait any longer, especially since some leaks were directly over electrical
equipment.
Mr. Lopez and Mr. Mestetsky replied to an inquiry from Member Pilecki
about the work associated to replacing a collapsed slip-liner(a method
used to continuously line an existing pipe) inside a 30-inch pipeline (slide
15). It was explained that pressured groundwater attributed to the failure of
the collapsed liner, some of which folded, that had been installed
approximately in the 1980s and was part of a pipeline acquired from
another agency. The liner was too thin (early technology) and the pipe,
which runs down a hill, was corroded. Mr. Lopez said that part of this
replacement also included filling in the angular spaces within the pipe to
resolve any future problems on this gravity line.
Each project was reviewed; however, the following were of specific note:
1. As part of the Plant Energy Optimization project (slide 4), Mr. Lopez
advised that the District has benefited from a payback of just under
three years.
2. The Piping Renovations series of projects approximately began in the
year 2000; staff just completed Phase 9. These project phases have
been a great learning tool for the engineers as they are designing
these projects in-house rather than being consultant driven, except for
any specialty work that may be part of a phase.
3. As it pertains to the Collection System easement and aerial crossing
work, the pictures show a small glimpse of the challenging work that
can be associated with pipes located within backyards, on hillsides,

etc., as well as the necessary coordination with residents, which has
been even more challenging during the pandemic.
The Committee commended the work on the projects. Chair Nejedly
added that the District receives very few complaints, which shows the
good work that goes into completing these sewer renovations projects.
COMMITTEE ACTION: Received the report.
5. Announcements - None.
6. Suggestions for Future Agenda Items
a. Receive list of upcoming agenda items and provide suggestions for any
other future agenda items
Earlier this year, the Board unanimously voted to delay the establishment
of a pilot Septic-to-Sewer Financing Program due to uncertainties of the
pandemic and the timing to launch a pilot program. As some time has
elapsed, the Committee requested that the topic once again be presented
to the full Board for consideration.
COMMITTEE ACTION: Received the list and provided input to staff.
