While Schomberg, King City and soon to be Nobleton properties are serviced by municipal sanitary sewers; the remainder of properties within the Township relies on private sewage systems (septic systems) for their sanitary servicing needs.

Sewage System Permits are required to ensure properly functioning sewage treatment systems are installed and meet with the minimum requirements of the Ontario Building Code. This will ensure that drinking water sources, surface water and the environment are not polluted.

January 1st, 1999 the responsibility for sewage (septic) systems plans review and inspections was transferred from the Region of York Health Department to the Township of King Building Division. Sewage system applications are available from the Building Division.

This change benefits residents as it allows for "one stop shopping". If you are building new, renovating, planning an addition, installing a lawn irrigation system or installing a swimming pool you will need approval for with respect for the sewage system (capacity and location). You will apply for this approval with the Building Permit Application at the Building Division.

Septic Maintenance:

  • Pumping your tank on a regular basis is the most important step you can take to ensure the health of your family and surrounding properties.

  • A family of four with a 1000 gallon tank (4500 Litre) would normally pump every two years. While your tank is being pumped, be sure to have your contractor check that the inflow and outlet pipes are free of blockages, and all required baffles are in place.  Newer septic tanks will have an outlet side effluent filter installed with an access riser.  This filter should be monitored and cleaned as required to maintain proper flow-through.

  • Keep a detailed record of repairs, pump-outs, inspections, permits issued, and other maintenance activities.

  • If you have only a sewage system holding tank (with no leaching bed) you will obviously need to pump-out more often, as frequently as every week or two, depending on usage and size of tank.

Never put the following into a sewage system:

  • Excessive fats, oils and grease,

  • Gasoline, oil or antifreeze,

  • Varnishes, paints and solvents,

  • Caustic drain and toilet bowl cleaners,

  • Photographic solutions, excessive bleach, pesticides and nail polish remover,

  • Tampons, sanitary napkins, diapers, facial tissues and condoms,

  • Plastics of any kind,

  • Coffee grounds, egg shells and other kitchen waste,

  • Cigarette filters.

Indictions of potential sewage system problems:

  • Toilets or drains which are backed up or run more slowly than usual, 

  • Foul odours in the house or drinking water,

  • Sogginess in the ground around the septic tank or leaching bed area,

  • Surface ponding of sewage effluent around the sewage system,

  • Activated alarm signals on secondary/tertiary treatment units or pump chambers,

  • Pumps which run constantly or not at all,

  • Unusually green or thick grass growing in or around the leaching bed area,

  • Significant algae growth in or around nearby water bodies,

  • High levels of bacteria or other contaminants in well water.

Maintenance Tips:

  • Conserve water. 

  • Space large water using activities such as multiple loads of laundry.

  • Avoid septic stimulators and additives.

  • Give your septic system a healthy diet.

  • Take precautions to protect your system -- don’t drive or park vehicles on top of the leaching bed.

  • Do not Plant trees or shrubs too close to your leaching bed or tank(s). Roots can cause damage and clog your leaching bed (especially willows, silver maples and poplars).

  • Do not change your property's drainage pattern. 

  • Do not bury your leaching bed under landscaping materials (such as plastic) or pavement; water must evaporate from the leaching bed for it to work efficiently.

  • Do not bury your septic tank under a driveway or landscaping features. The tank must remain accessible for inspections and pumping.
