Customers of the Santa Fe Irrigation District (SFID) are looking at double-digit increases in their water bills next year, based on a proposed spending plan that will be considered for adoption by the district’s board of directors in June. The rate hike, which is planned for Jan. 1, 2018, will total between 11 and 13 percent, said Jeanne Deaver, the district’s administrative service manager. This includes a 9 percent rate hike imposed by the district, plus a “pass-through” of between 2 and 4 percent based on expected rate increases by the district’s wholesale water supplier, the San Diego County Water Authority.
