SS1301
SUMMARY OF REQUEST:
That the City Council adopt Resolution 6840 approving the 2018 Sewer Master
Plan Update, 2018 Sewer System Management Plan, 2018 Sanitary Sewer
Emergency Overflow Response Plan, and 2016 Sewer System Management

BACKGROUND AND ANALYSIS:
At the November 9, 2015 City Council Meeting, the City Council approved an
agreement to update the Sewer System Master Plan, Sewer System
Management Plan, Sanitary Sewer Emergency Overflow Response Plan, and
Sewer System Management Plan — Program Audit.
The City's sewer service area encompasses 1,705 acres including the Seal
Beach Naval Weapons Station. The City's sewer service area does not include
College Park West, Leisure World, Centex Homes, Montecito Homes, Shops at
Rossmoor, Old Bolsa Chica Road, or Surfside, as these areas are maintained
internally or by outside sewer districts. The City's existing sewer collection
system is comprised of approximately 181,000 feet of pipe ranging in size from 6
inches to 24 inches in diameter. The City maintains 780 manholes, 5,000 service
connection, and six sewer pump stations and their associated force mains.
The overall goal of implementing a Sewer System Master Plan is to evaluate the
existing condition of the sewer system, ensure adequate capacity exists to
effectively collect and transport sewage generated in the City, and identify and
plan for needed capital improvements to the system. The plan also helps to
ensure that the City remains compliant with new and constantly changing State
regulations related to sewer system management.
Agenda Item M
The City's existing Sewer System Master Plan and Sewer System Management
Plan were last updated in 2005. At that time, the plans identified approximately
$15 million in needed capital improvements to the system. The improvements
include pipe upsizing to increase collection capacity, improvements and repairs
to existing pipelines, and pump station improvement projects. Since 2005, the
City has spent over $16.7 million on sewer capital improvement projects.
The 2018 Sewer System Master Plan updated the entire system and identified
capital improvements for the next 15 years, as well as updated regulatory
documents as required by the State. The 2018 Sewer System Master Plan
scope of work included:
-Establishing performance standards for the existing wastewater collection
system using information from closed circuit television (CCTV) inspections
performed in 2013 and flow data collected from all six pump stations during FY
2014 -15.
-Developing a hydraulic model that is capable of simulating the operating
characteristics of the wastewater collection system under various conditions,
including future system scenarios.
-Performing capacity analysis of the wastewater collection system based on the
results of the hydraulic model to identify capacity deficiencies.
-Updating the capacity analysis and condition assessment of the wastewater
collection system to develop a list of prioritized capital improvements. Over $16.2
million dollars was identified in need of rehab, replacement, or further evaluation.
-Updating the City's Sanitary Sewer Overflow Emergency Response Plan to
ensure compliance with existing State regulations.
*Conducting a Sewer System Management Plan audit as required by State
regulations.
-Updating the City's Sewer System Management Plan to ensure compliance with
State regulations.
The 2018 Sewer System Master Plan, 2018 Sewer System Management Plan,
2018 Sanitary Sewer Emergency Overflow Response Plan, and 2016 Sewer
System Management Plan — Program Audit are now complete to the satisfaction
of the Public Works Director and are available in the City Engineer's and the City
Clerk's office for review.
