Pleasanton is set to see a 5.5% rise in the annual rates for wholesale water services from the Zone 7 Water Agency for each of the next four years after its Board of Directors voted 5-2 to approve the price increase last week. Intended to help fund water treatment efforts and regional supply projects as well as maintain Zone 7 operations and reserves, the first new rate will go into effect in February and each subsequent rate increase will occur on Jan. 1 of each year.
