The borough of Summit Hill was left without water today when an electrical problem in the pumping system malfunctioned. Authority members, the work force, and electricians were at the site of the Bloomingdale (White Bear) system all day in an attempt to rectify the situation. The problem apparently occurred when a motor burned out at the pumping station. The result was that the town's 500,000 gallon holding tank, located at the southwestern portion of town, went dry.
