SUPPLEMENTAL MATERIAL MARCH 19, 2024 1 of 2 Responses to City Council Agenda Items – March 19, 2024 Agenda Item #10 Water System Activities Update 1. Q. Does the booster equipment that the City rented last year for the Zone 7 turnout, along with interim water system adjustments already made, mean that the city is in much better shape to meet this year’s summer peak demand than last year? A. The City will be in better shape this coming summer with improvements that are currently under construction and anticipated to be in service before peak summer demands, in addition to the continued rental of the booster pump at Turnout #4. The improvements include upgrades at Turnout #1 and 1,600 liner feet of new 18" pipeline on Bernal Avenue which is currently under construction. The City is also building off the lessons learned last summer on how to reduce the water needs during peak demands by partnering with large water users to reduce use. 2. Q. Further, the pending $14M in [water system] improvements that are planned (1) Would obviate the need to continue renting the booster equipment, A. That is correct. The loan covers a new pump station at Turnout #4 that will replace the rental pump. (2) Enable the city to meet higher peaking demand further in the future, and A. That is correct. The new pump station at Turnout #4 and pipelines were designed to meet current and the systems future demands based on hydraulic modeling results. (3) Make progress on being able to operate the system as optimally and economically as practicable (assuming that additional future improvements are made). A. That is correct. The pipelines were upsized where appropriate to take additional capacity for lines that are at the end of their service life and will soon have to be decommissioned, providing the most economical solution. In addition, the improvements were identified as needed to re-balance and optimally run the system, and are needed for all of the Water Supply Alternatives options. 3. Are we as a city “not hopefully staving off the peaking problems this summer as fast as we can?” (Quote in the Pleasanton Weekly) A. That is correct. The City entered into expedited design contracts in August 2023 and within six months had started construction on the most critical section. An item is being presented to the City Council this meeting to award the remaining pipelines. Construction will begin as soon as materials can be procured by the contractor. The City also worked on procuring critical valves that have long lead times to speed up start of construction. The prefabricated pump station would not have been in service this summer due to a 9-month fabrication time frame and the City is using the additional time to value engineer the project to reduce costs.
