LAJA Wastewater Facilities Operation

ARRO has been operating the wastewater treatment plant for the Lewisberry Area Joint Authority since January 2001.

The 100,000 gallon per day activated sludge plant consists of a main influent submersible pump station, flow equalization, extended aeration, final clarification, and effluent disinfection utilizing ultraviolet light technology.

ARRO's efforts have included laboratory testing revisions and testing of alternate chemicals, flow distribution system changes, treatment process and air distribution, modifications, and sludge dewatering for more cost-effective treatment.

"The Authority has been more than satisfied with the quality of work, and the cooperation of the operators. There have been several improvements made at the plant, primarily based on recommendations from ARRO."

William Thompson, Secretary/Treasurer
