The update of the Rainbow Water District capacity charges included allowing for smaller meters. The Rainbow board voted 4-0, with Hayden Hamilton absent, July 27, to approve the revisions in the district’s capacity fee ordinance which also changes the wastewater capacity fee variable for single-family homes from number of bedrooms to square footage of the house. Capacity fees are one-time charges to developers who purchase system capacity for water and sewer services. “It’s primarily a buy-in charge,” Rainbow general manager Tom Kennedy said.
