INTRODUCTION
The purpose of this memo is to summarize the status of the Sanitary Sewer Asset
Management Plan (SSAMP) program to be presented by staff during the special work
session with City Council on March 4, 2024. During the work session staff will present
on the program and provide City Council with an update on the status of the program,
review the results from the preliminary analysis performed to date, and to discuss the
anticipated next steps for the program.
BACKGROUND
Management of the City's sanitary sewer collection system requires an understanding of
how its aging infrastructure is performing in older areas of the City and how potential,
rapid expansion related to growth from the completion of the Southwest Arterial and
newly annexed areas might impact the sanitary sewer collection system. To maximize
the return on investment as to how all sewer utility dollars are spent in combination with
constrained capital and operating budgets, an asset management plan that identifies
and helps prioritize the sanitary sewer improvements necessary in the short-, mid-, and
long-term to ensure the system continues to meet the needs of the community and to
provide planning level budgets for all recommendations. The consultant will assist City
staff in establishing a strategic and proactive plan for the management of the sanitary
sewer system that shall:
• Develop repeatable and dynamic processes that enable staff to quickly evaluate
asset data to assess condition, level of service, and criticality.
• Rank sanitary sewer capital improvement projects based on risk analysis and
system performance.
• Identify sanitary sewer utility staffing and resource needs.
• Optimize existing operations and maintenance procedures.
During the May 1, 2023, City Council meeting, the Council authorized the City Manager
to negotiate a contract with HDR Engineering for the City's SSAMP. On June 13, 2023,
the City Manager authorized the negotiated Master Services Agreement with HDR
Engineering as well as the initial Task Order #1, which pertains primarily to the
collection and analysis of the available sanitary sewer system data and engagement
with City staff through workshops to identify current staff procedures, needs, and goals.
On September 9, 2023, the City Manager authorized the next Task Order #2, which
pertains primarily to the development of a system wide hydraulic model to analyze the
existing sanitary sewer system capacity as well as to begin coordination with the
Planning Services Department on the City's goals for future growth planning.
For each of the initiated task orders, HDR Engineering has provided City staff with
thorough updates detailing the results of each analysis performed to date. HDR
Engineering is also developing a proposed "Road Map" for the Sanitary Sewer Asset
Management Plan which propose a schedule future initiatives and task orders based on
the identified system needs and priorities.
