Treatment Plant
Sewer UtilityWastewater from Charlottetown is collected by the City’s sanitary sewage system and transported to the Treatment Plant on Riverside Drive.  A number of homes in the East Royalty area have its wastewater transported to a lagoon for treatment.  The Treatment Plant is an activated sludge secondary facility that reduces BOD and suspended solids.  It also uses ultraviolet disinfection that negates the need for chlorine gas and aeration to facilitate a reduction in ammonia.  These factors improve the quality of effluents in the Hillsborough River and the Charlottetown Harbour, thus fostering recreational and fish/shellfish industry confidence in the quality of the City’s water environs. 

Biosolid treatment outcomes equivalent to “Class A” as defined by the EPA Part 503 Rule. Upon testing, the biosolids have been shown to meet the criteria needed for an “Exceptional Quality” biosolid that has no restrictions on end use.

Sewer Installations
If you are planning to install a sewer service to your property, an Application for Service is required and installation shall be in accordance with the requirements set by the Utility. When installing a cleanout, it should be in an area to be easily accessible should problems occur. In the case of a building so located that any plumbing fixture in the building is below street level or so as to be affected by a back flow on the sewerage line, such premises shall be provided with a suitable check valve.

Infiltration and Inflow (I/I) occurs when storm water or groundwater enters the municipal wastewater system. This water enters the sanitary sewer system through cracked pipes, leaking manholes as well as downspouts and sump pumps from homes that are connected directly to the sanitary sewer system. Downspouts and sump pumps are considered illegal connections and are not permitted.

The storm water that enters the sanitary system adds to the daily volume of wastewater that must be collected, pumped and treated the by the Treatment Plant. When too much water enters the system, problems may occur.
