The increases, approved Thursday, will raise United Water’s annual revenue by $2.6 million. They are mostly related to water system improvements and higher operating costs, particularly treatment costs, the company said.
Average monthly rates for residential customers using 5,000 gallons monthly, including taxes and surcharges, will rise $2.52, or about 8 cents a day, according to company spokesman Bob Manbeck.
United Water initially requested a rate increase yielding $4.94 million in additional revenue. The company said it has invested more than $23 million in system improvements since rates last rose in 2006.
United Water Pennsylvania Inc. serves about 56,000 customers in Columbia, Cumberland, Dauphin, Luzerne, Perry, Schuylkill, Wyoming and York counties.
