Sewage

Residential communities will be serviced by communal on-site sewage disposal systems which are not serviced with municipal wastewater and water distribution systems. Provincial regulations allow for communal on-site sewage disposal systems, subject to approval of a management plan. It must contain measures to ensure land owners are responsible for the maintenance of these systems.

and other contaminants to enter groundwater and surface water which may pose health risks and cause environmental degradation. Contamination has resulted in closures to swimming and has increased

the eutrophication process of lakes and estuaries. People must protect

the environment by undertaking an on-site sewage disposal system inspection program and to require homeowners to install devices which can extend the life of, or improve the performance of on-site systems.

The risk of inadequate performance of on-site sewage disposal systems in areas which are serviced with a central water supply is of grave concern to the society. There is a higher degree of risk of on-site sewage disposal system failure in areas serviced with central water because the unlimited source of water can cause hydraulic overloading.

Regular maintenance would reduce the risk of failure. This might be achieved by adopting a by-law that requires regular system maintenance of private on-site sewage disposal systems or by establishing Wastewater Management Districts in which funds are collected from owners within the district for system maintenance. Financing for system maintenance might also be included in the cost of providing central water.
