The agency that sells treated water to Pleasanton and the rest of the Tri-Valley is poised to adopt four years of rate increases at once.
The Zone 7 Water Agency board meets Wednesday, Oct. 21, at 7 p.m. at its administration building, 100 N. Canyons Parkway in Livermore, and is asked to adopt wholesale treated water rates for 2027 through 2030. The schedule raises rates 4.5% a year.
The board heard the rate study in August and agreed to the 4.5% figure in September, directing staff to bring back a resolution this month.
What changes
Zone 7 charges its customers in two parts: a yearly fixed charge, split among them based on a two-year rolling average of how much water each used, and a price per 100 cubic feet of water delivered. The volume price would go from $2.47 now to $2.59 on Jan. 1, then $2.70 in 2028, $2.82 in 2029 and $2.95 in 2030.
Total fixed charges would rise from about $33.3 million this year to $34.8 million in 2027 and $39.7 million by 2030.
Among the four retail water providers that buy from Zone 7, the City of Pleasanton carries the largest share. Its 2027 fixed charge would be about $13.13 million, up from about $12.61 million in 2026. The Dublin San Ramon Services District would pay about $9.89 million, the City of Livermore about $5.89 million and California Water Service about $5.62 million.
Smaller direct customers include Lawrence Livermore Laboratory, at about $175,000, and the Veterans Hospital, at about $51,000.
The agency's consultant, Water Resources Economics, estimated what the wholesale charges amount to for 15 hundred cubic feet of water a month: $69.80 now, rising to $73.07 next year and $83.30 by 2030. The agenda materials do not say how the increase would show up on Pleasanton residents' bills.
