Full report
Issaquah, Washington has proposed a $9.34 million, two-year water capital programme that would begin planning and conceptual design for a future water treatment plant while funding major booster-station, distribution and metering works.
The programme, presented as part of the city's proposed 2027-28 biennial budget at a 5 October public hearing, contains $5.33 million of water capital expenditure in 2027 and $4.01 million in 2028. It covers 12 projects. The council took no budget-adoption action at the meeting.
The largest single 2027 allocation is $2.39 million for the Central Park Booster Station retrofit. The budget also proposes $900,000 per year for the Water Main Replacement Program, $582,000 in 2027 and $1.60 million in 2028 for the Water Treatment Plant project, and $396,841 in 2027 for the Talus 1 and 2 booster-station retrofit.
The city's Public Works budget narrative says the Utilities Engineering Division will update the Water System Plan under Department of Health rules to reflect growth projections, new development, revised service plans and capital improvements. It also says the city will initiate planning and conceptual design for the future water treatment plant after a site determination expected in late 2026.
Further planned water works include $535,500 in 2028 for the SE Newport Way pressure-reducing-valve master meter; $518,000 in 2028 for the Terra II Booster Station retrofit; $200,000 in 2028 for Summit Reservoirs retrofit; and $263,500 in 2027 for Gilman Well House and Equipment Replacement. The 2027 programme also includes $250,000 for a Montreux chlorine analyser and $300,000 for a water-system seismic-resiliency study.
Metering is another defined component. The capital plan assigns $40,000 in 2027 and $220,000 in 2028 to wireless meter-reading implementation, while separately providing $200,000 in each year to replace meter transmitter units. Public Works said it would partner with IT, utility billing and utilities engineering to develop and begin implementing advanced metering infrastructure.
Operational priorities include completing the upgrade of water-facility SCADA communications to cellular protocol and associated security upgrades; increasing pressure-reducing-valve inspections and control-valve maintenance; revising the coliform monitoring and sampling plan; inspecting and retrofitting air-vacuum release valves in the floodplain; and completing an EPA-required lead service-line inventory update.
The proposed Water Fund shows revenues of $19.14 million in 2027 and $19.70 million in 2028, with expenditures of $20.28 million and $18.94 million respectively.
