Capital Improvement Program Review (1998-99)
Dear Rob
I have completed my review of the District s 1998-99 Capital Improvement Program (CIP) that
you sent me on Jude 17 1998 1 have enclosed my independent review report as you requested.
As usual, I found the CIP report to be very complete, containing adequate information for me to
make my review The use of letters, vicinity maps, and recap sheets was beneficial, It made my
review easier
Overall, I found the CIP report to be very concise, well defined, and complete. I applaud you
and the District for continuing the funding for future sewer replacement and funding for
earthquake and major emergency sewer repairs. The District s management and financial ability
to provide these services without increasing fees should be promoted to the end users, the
residents, and businesses of Costa Mesa. Projects No 161 and No. 163 will not only provide a
safer working environment but should help the efficiency of handling a major power failure. I'm
sure the field crews will appreciate the District s expenditure for these two projects.
I look forward to seeing your research results on sewer age and the use of enzymes for odor and
grease control. I would hope that you and the District would consider publishing the results of
your investigations; this could go a long way in showing the end user that the District is a
forward thinking agency
I appreciate the opportunity to continue to work with you and serve the District. Best wishes to
you, the Directors, and the District staff

Capital Improvement Program
Fiscal Year 1998-99
♦ Project 1112100-149 / Sinking Fund for Future Sewer Replacement
This is the fourth year (project was initiated in the 1995-96 fiscal year) that funds have been set aside
for future replacement or reconstruction of sewer lines as they reach life expectancy Setting aside
funds for future use will benefit from the compounding of interest over time. The report indicates
that funds can be set aside without affecting existing sewer user rates; this continues to be a point
worth promoting. To date, $700,000 has been deposited into this fund.
The report indicates that the District Engineer is conducting research of Eastern and Midwest
municipalities where various existing sewer systems are older than 100 years. Information from this
research should be of great value to the District in planning its future. This reviewer would be
interested in the results of the research.
• Project 1112100-156 /Earthquake/Major Emergency Sewer Reconstruction Fund
This year s allocation continues the funding established in 1997 The District s goal is to set aside
$1,000,000 in the event of an earthquake or other major emergency The reviewer concurs with the
reasoning behind establishing this fund. As stated in last years review tither sources of
funding/reimbursement may be available (i.e. State, FEMA, etc.)• however these sources will
probably not be timely nor is there a guarantee that full reimbursement will be available. It appears
that the District continues to have the financial resources available which will allow continuation of
this fund without affecting other District operations nor cause an increase in fees. This fund (as does
Project No. 149) will continue to benefit from compounding interest over time.
With this years allocation of$150 000 the total deposit into the Fund equals $600,000
It appears that with good management and sound financial controls, the District continues to be able
to provide service and protection to the District s constituents without increasing fees. Again, a
point worth promoting.
• Project 1112100-159 / Televising Sewer Lines
This year s project is part of an ongoing program to insure that the District s facilities are
functioning properly In reviewing the cost data provided, the per linear foot cost for televising has
increased at a minimal rate. The engineering fees are higher than normal projects but since this
requires proper selection of locations to be televised, monitoring the District s cleaning schedule,
coupled with reviewing the tapes and report preparation, they are acceptable.
0C-C62100-08/gw/CMSDRPT DOC t 130VLE
The reviewer recognizes that the District Engineer prepares a report which defines the results of this
project; however it might be beneficial for future years to provide a very brief summary of the value
of this type of work. A brief indication of percentage of pipeline unchanged versus continued
deterioration, versus actual repairs would provide support for funding continuation.
• Project 1112100-160 / Fairview Park Sewer Line
This project will provide a gravity sewer through a portion of Fairview Regional Park and will
initially provide rest room service for the Orange County Model Engineers (OCME), with future
service for other rest room facilities. This will also allow the OCME to expand its facilities and to
add a snack bar The District Engineer s letter of May 15 1998 to the City Manager was provided as
supporting information. It is understood that this is a capital improvement project (as compared to a
capital replacement project) and that the City and OCME will contribute to the construction fund. It
is also understood that this project will only proceed subject to a final agreement between the City
and the District.
The design and inspection costs appear to be high (30 percent of estimated construction costs) unless
these costs also include surveying and geotechnical services.
e Project 1112100-161 / Construct Water Service to Pumping Stations
Throughout the years, the District has conducted various safety type projects, i.e. converting climb-
in wet well-dry pump stations to submersible where checking could be done from above ground.
Also, staff has gone through training and are certified by OSHA for entering into the remaining wet
well-dry well stations. This project will add a potable water supply to each of the 11 largest pump
stations, thus allowing for immediate wash down in the event of chemical and/or hazardous material
contact. Considering the number of locations and two different Water Districts to deal with, the
proposed budget appears reasonable.
s Project 1112100-162 / Enzymes for Grease /Odor Control (Pilot Program)
This pilot project will initiate the use of enzymes to control odor and grease. The present use of
hydrogen peroxide for odor and a de-greaser sometimes counteract each other when used together
The District is presently spending $60 000 per year for odor and grease control and this may not be
the best usetf the District s funds. The reviewer understands that CSDOC and the Rossmoor/Los
Alamitos Area Sewer District may also be experimenting with the use of enzymes and is
investigating its use. The District may want to contact these other agencies to share and compare
notes. The budget appears reasonable.
• Project 1112100-163 / Upgrade Emergency Response Equipment
The reviewer is very familiar with the effects of a power outage or electrical failure on a sewer pump
station. The reviewer is also familiar with the use of by-pass pumps in the event of a power failure
or break in the main line. This project will purchase generators and will modify the electrical system
at 11 of the most critical pump stations. This will allow for the generators to be connected directly
0C-C62-100-08/gw/CMSDRPT DOC 2 BOYLE
to the affected pump station electrical panel, will keep the station operational, and should eliminate
the need of always relying on by-pass pumps.
The budget of$140,000 appears reasonable since it also includes a new advanced design root cutter
♦ Project 1112100-164/ Miscellaneous Sewer Work/ Manhole Adjustment
This provides the funding for a continuing program to reimburse others for work that they either do
or have done on District facilities. The program has been expanded to include small sewer line
repairs that need to be handled immediately
Other agencies perform construction activities which affect District facilities, i.e. raise or lower
manholes to grade. Since the District is responsible.for its own facilities, providing funds to
reimburse other agencies is appropriate. The reviewer understands the benefit of expanding the
program to provide funding for small sewer lines and manhole repairs/adjustments, when the need is
found rather than waiting to include them in a larger project.
Based on the data contained in the engineers report, the funding amount appears reasonable.
