Over the last five years, the Public Works Department has worked to assess and rehabilitate the water and sewer infrastructure throughout the City. While much work has been completed, such as the purchase of new variable frequency drives and new submersible pumps for the sewage stations, the overall system is in dire need of a complete renewal and replacement program. While staff continues to work on strategic initiatives to improve the state of the water and sewer system, much of the work completed to date has been addressing emergency projects.
In order to commence a long term capital program that would address the City’s aging water and sewer infrastructure, the Department of Public Works procured the professional services of various water and wastewater consultants in 2017. Immediately after negotiating the contract, the Department developed an engineer’s report of the water and wastewater system, a necessary document to secure new utility bonds. Those were subsequently successfully secured. The Department also commenced an effort to visually assess all above ground assets to determine their critical needs. This effort culminated with the 2018 Renewal and Rehabilitation (R&R) Report, which again documented the overall state of disrepair of the water and wastewater system.
While the R&R Report was underway, the Department began digitizing over 10 years of as-built data in order to map the city’s water and sewer system – a requirement to develop a hydraulic model and a master plan. This effort took a year to complete, as many records had not been properly kept and most records had never been digitized. Once the systems had been mapped on GIS, the hydraulic models could be developed and calibrated. Leveraging the hydraulic models and the R&R Report, the 2019 Water and Sewer Master Plans were developed to address the systems’ needs through a 25 year planning horizon. Along with the master plans, a 5 Year Critical Needs Capital Plan was developed.
At the October 23, 2019 Sustainability and Resiliency Committee (SRC) meeting, staff provided the members of the Committee a progress update on the Water and Sewer Master Plan. The Administration stated it has reviewed the plan and was ready for the Finance and Economic Resiliency Committee (FERC) (formerly the Finance and Citywide Projects Committee) for review and to further discuss a financing plan. The SRC Committee made a motion to refer the Water and Sewer System Master Plan to the FERC to identify funding sources.
At the January 27 Resilience Retreat, the Department presented the 5 Year Critical Needs Capital Plan, to the City Commission. Following the retreat, at the February 28, 2020 meeting of the Finance and Economic Resiliency Committee (FERC), staff presented the 5 Year Critical Needs Capital Plan and the committee made a motion to proceed to the full Commission to seek acceptance of the plan for the City’s water and wastewater system, and approval of the $24 Million available from bond proceeds subject to a future appropriation. Additionally, the FERC recommended commencing a rate study of the water and wastewater utility to determine financial capacity for the water and wastewater work associated with the Jacobs Engineering neighborhood prioritization and the remaining $61 Million of critical needs.
At its March 18, 2020 meeting, the City Commission made a motion to accept the recommendation of the Finance and Economic Resiliency Committee, to accept the five-year critical needs capital plan for the City's water and wastewater system, to approve the use of the $24 Million available from bond proceeds, and to commence a rate study of the water and wastewater utility to determine financial capacity for the water and wastewater work associated with the Jacobs Engineering neighborhood prioritization and the remaining $61 Million of critical needs.
The Public Works Department is working with multiple design consultants and contractors on the implementation of high priority critical needs projects. In addition, some of the projects are being designed by Public Works.
