Sugar Run Dam Rehabilitation

Originally constructed in 1907, Sugar Run Dam is a 900-foot long, 60-foot high, earth embankment dam impounding approximately 140 million gallons of water for the Highridge Water Authority for it’s customers in Westmoreland and Indiana Counties. After being damaged by flooding, the PA DEP ordered that the dam be drained due to stability concerns. Gibson-Thomas oversaw the design and construction of the rehabilitation of the structure, including new chimney and blanket drains, buttress fill, auxiliary spillway, and intake tower. This $3.5 million project was funded through a combination of PennVest loans and H2O grants to return this important water resource to service.
