Zone 7 water rates likely to increase
Water rates will likely rise as a result of challenges currently facing the Tri-Valley’s Zone 7 water supplier. Reduced sales during the drought, forever-chemical treatments, and state infrastructure contributions all loomed over the agency’s four-year rate study that discussed annual rate increases between 2.0 and 9.5 percent, with the board favoring the higher end, at its Sept. 21 board of directors meeting. … As the Tri-Valley’s water wholesaler, Zone 7 provides water to local retailers — Pleasanton, Livermore, the California Water Service, and the Dublin San Ramon Services District — for final treatment and delivery.
