CMSD SANITARY SEWER OVERFLOW (SSO) STATISTICS, RISKS AND
MAINTENANCE UPDATE
Mr. Fauth presented the overall Sanitary Sewer Overflow (SSO) statistics for 2007 which
remain unchanged since June 15, 2007 — grease caused five SSOs, tree roots caused
one SSO and Other issues such as debris blockage and a pump station bubbler failure
caused two SSOs. Of note, zero SSOs have occurred in areas National Plant Services,
Inc., (NPSI) have cleaned District main lines. Mr Fauth and Mr Hamers identified recent
telemetry issues including the recent loss of a Verizon Cell Tower. This loss limited
telemetry to allowing stations to call into the SCADA alarm but did not allow CMSD
interrogation of 13 individual pump station Remote Terminal Unit (RTU) sites. TRC
validated the status such that there was not a loss in reporting to the SCADA alarm.
Director Ooten suggested considering alternative options as backup for the telemetry.
Paul Guzman suggested researching the feasibility of using land - lines. Mr Hamers
suggested Staff research the possibility of TRC incorporating a signal indicating a

"COMMUNICATION ERROR" to first responders, if possible, especially for catastrophic
failures.
Mr Fauth discussed the process for reporting "NO SSOs" and validating the Sewer
System Management Plan (SSMP) in the California Integrated Water Quality System
(CIWQS).
Staff continues to evaluate options to address the highest risk pump station (PS)
concerns such as to back -up or potentially replace PS bubbler systems. Mr Fauth
presented the "Prioritized Pump Station Retention Times" chart identifying the criticality
and hours of wastewater retention by PS. Canyon PS is the most critical with a one hour
retention time and 21 st St PS is the least critical with a 10 hour retention time. Mr Fauth
and Mr Dulake explained the "CMSD Pump Station Risk Analysis" chart identifying the
potential factors from low to high risk and from low to high frequency of occurrence. The
factors are categorized and will be placed objectively on the chart. Mr Dulake presented
the CMSD Pump Station Maintenance Chart. Director Ooten suggested employing a
thermography (Infrared Thermal Imaging) technique to detect heat in control panels. Mr
Guzman recommended identifying PSs with and without surge protection. Additional
detailed Risk Analysis for preventing PS SSOs will be presented at the August 13, 2007
Sewer System Subcommittee meeting.
POTENTIAL TRANSFER OF SEWER LINES FROM OCSD TO CMSD
Mr Hamers discussed the potential transfer of two OCSD lines to the CMSD, a 15" line in
Bear Street and an 18" line in Avenue of the Arts, with OCSD representatives. This
would effectively transfer these lines from a regional large diameter pipe agency to a
local agency. A regional agency generally owns and maintains sewer lines with large
diameters (greater than 30 inches). Local agencies generally transport sewage to these
trunk lines. Discussion centered on historical transfers and the rationale for the transfers.
Following CCTV and any required line repairs, the transfer would result in additional
revenue for CMSD at little cost for CMSD to maintain the lines. These locations have
Food Service Establishments (FSEs) and require Fats Oils and Grease (FOG)
management within the CMSD. Director Ooten recommended notifying the site owners
of the transfer while the transfer documentation is in development. Mr Hamers will
present the topic to the Board at the August 9, 2007 CMSD Regular Board Meeting.
CMSD PROJECT #101 - WESTSIDE PUMP STATION ABANDONMENT
The two options OCSD costed are as follows:
1. Option 1: $9.0 M for a gravity flow system.
2. Option 2: $6.6 M to rebuild the City of Newport Beach Pump Station and the
force main.

Mr Hamers is preparing the projected CMSD costs.
SEWER LATERAL ISSUES
Mr Hamers reviewed the purpose of the draft "Sewer Lateral and Clean Out Financial
Assistance Program" and accompanying Application to assist residents requiring lateral
repairs and clean out installations. The, draft states "CMSD will contribute 50% of the
residents' costs up to a maximum of $1,800 ". The purpose is to encourage residents to
maintain (clean and CCTV) their laterals on a regular basis to achieve zero SSOs. Mr
Hamers explained the draft "Sewer Lateral "Surge "" flyer to be distributed to facilities with
a history of experiencing or potentially experiencing a surge during CMSD main line
cleaning.
Staff included the Lateral Assistance program in the 5 -Year Capital Improvement
Program for FY 2007 -08 Through FY 2011 -12 at a level $100,000 per FY. Director
Monahan recommended press releases for all high visibility District projects such as the
Lateral Assistance Program, District website launch, and other Special Programs.
CMSD EMERGENCY RESPONSE - DISTRICT YARD UPDATE
Staff continues to coordinate with Mr Don Gregg to acquire the site at 174 West Wilson
Street. Mr Fauth presented the draft architect site plans from Mr Bob Thornton of RTA,
the site architect. The site is envisioned as having a.5,460 SF building on an 18,200 SF
lot. The minimum District Yard requirements to respond to SSO emergencies remain as
follows:
a. Location: Centralized District location for equalized response;
b. Lot Size: 9,000 to 12,000 sq ft for outside storage and parking;
c. Building Size: 2,500 to 5,000 sq ft for office, hoist repairs and storage;
Siting issues include the availability of property, the property zoning (MG needed), the
City of Costa Mesa requirement for a conditional use permit (CUP requires 10 -12 weeks
to obtain approval) and the four zoning overlays in place. The overlays are:
1. South of Bristol Entertainment, Culture and Arts Urban Plan (SoBECA);
2. Mesa West Bluffs Urban Plan;
3. 19 West Urban Plan; and
4. Mesa West Residential Ownership Urban Plan.
Mr Fauth presented the "Annualized CMSD Crew vs Contractor Costs" chart noting the
annual cost savings of an in -house crew would be $216,947 over one year and
$2,169,470 over a 10 -year period, excluding inflation.
