Welcome to the Greater Greensburg Sewage Authority web site
The Greater Greensburg Sewage Authority (GGSA) owns and operates the Greater Greensburg Wastewater Treatment Plant (WWTP) and much of its sewage collection system.

The solids handling system consists of gravity thickening for primary sludge, mechanical concentrators for waste activated sludge, two-stage anaerobic digestion, and mechanical dewatering. The WWTP discharges into Jacks Run under NPDES Permit No. PA0027456.

The Greater Greensburg WWTP serves approximately 9,800 customers from the City of Greensburg, Borough of Southwest Greensburg, Borough of South Greensburg, and portions of Hempfield Township.

Effective Janaury 1, 2016 the user rates for GGSA customers were increased to $6.50 per 1000 gallons of metered water.  This increase was necessary due to needed repairs and improvements to the wastewater treatment plant and the sewer system.  Despite this increase, GGSA customers will continue to pay some of the lowest rates in the area.
