Mount Joy Borough received sewer in 1956-1957.  The first proposed site of the wastewater treatment plant was what is now the home of the Mount Joy VFW on Longenecker Road, but plans were approved in January 1956 to build the first wastewater treatment plant behind the Amos Nolt farm at the end of South Jacob Street.  The first start-up of the plant was in 1957.

In 1979-1980, the plant received an 8.5-million-dollar expansion totally changing the treatment process with activated sludge, extended aeration and polishing filters, bringing the hydraulic capacity to 1.53 million gallons a day.

In 2003-2004, a 6-million-dollar expansion took place bringing the organic capacity of the plant equal to the hydraulic capacity.  This upgrade also expanded the solids handling process to achieve a PA D.E.P Class “A” beneficial reuse product as final disposal.

In September 2010, the Authority completed its 3.5-million-dollar BNR (Biological Nutrient Removal) upgrade to comply with the new, more stringent Chesapeake Bay requirements. This upgrade focused on total nitrogen and phosphorous removal through the treatment plant by adding fine bubble diffusers to the aeration tanks, addition of 3 deep bed denitrification filters and the use of UV (ultraviolet) disinfection.

The Authority also had the opportunity to have a 385 KW solar panel system installed within the facility through grant funding and private investors.  This was a great addition to the facility, which had no financial impact to the Authority or customers.  Customers may also view the deck monitoring of the solar system by clicking the following link.
