What is the regulation respecting waste water disposal systems for isolated dwellings?

Please consult the regulation, in english regulation at this addresse : http://legisquebec.gouv.qc.ca/en/ShowDoc/cr/Q-2,%20r.%2022

(in french)
Le Règlement sur l'évacuation et le traitement des eaux usées des résidences isolées vise l'évacuation et le traitement des eaux usées des résidences de 6 chambres à coucher ou moins – et des bâtiments qui produisent un débit total quotidien d’eaux usées d'origine domestique d'au plus 3 240 litres. Ces résidences et autres bâtiments ne doivent pas être raccordés à des réseaux d'égout municipaux ni à des ouvrages d’assainissement collectifs. Le Règlement a pour objectif d’interdire le rejet dans l'environnement d’eaux de cabinets d'aisances, d’eaux usées ou d’eaux ménagères à moins que ces eaux n’aient reçu un traitement approprié. Ces eaux non traitées constituent un contaminant au sens de la Loi sur la qualité de l'environnement.

What is the frequance to pump a septic tank?

In the province of Quebec, septic tanks are required to be pumped every two years for full time residences and every four years for seasonal residences.

How can I ease emptying my tank

In general , it is up to the owner to make accessible the lid of the septic tank to allow the draining. To ease this task, you can add extension to the lid of your pit and / or replace your concrete cover with a plastique lid .Vous should also plan the landscaping of your yard accordingly.

How can I ensure that my system remains in good condition

  • Do not backfill more than 36 in. (90 cm) on top of a septic tank.
  • Clean the prefilter once or twice a year.
  • Installing a carbon filter on the house vent may eliminate odors around the house.
  • Do not construct parking areas, decks or skating rinks over the disposal bed and the tank.
  • Reduce water use, and consequently the volume of wastewater, by installing water saving fixtures in plumbing fixtures.
  • Spread out the use of washing machines and dishwashers over several days.

Warning signs of a defective septic system

  • Toilets or other plumbing fixtures back up or take longer than usual to drain.
  • Bad odors noticeable in the house or in the drinking water.
  • Soggy ground around the septic tank or disposal bed.
  • Wastewater or effluent patches around the septic tank.
  • Particularly green or thick grass over the surface of the disposal bed.
  • Significant growth of algae in surrounding lakes or watercourses.
  • High levels of nitrate-nitrogen, bacteria or other contaminants in the well water.

What not to put down the drain?

Because septic systems rely on bacteria to break down the waste material, it is important that you don’t poison these micro-organisms. Even small amounts of paints, solvents, thinners, nail polish remover and other common household compounds flushed or poured down the drain can kill the bacteria that break down the organic matter in the wastewater. Household disinfectants such as laundry bleach or toilet bowl cleaner can be used in moderation without affecting the operation of the septic system; however, overuse of disinfectants can kill the bacteria in a septic tank. Some manufacturers promote the use of septic tank “cleaners”, “starters” or “enhancers” to aid in the digestion of the waste. These products are typically of little value and are not recommended.

You should avoid putting anything into the septic system that doesn’t break down naturally or anything that takes a long time to break down. Materials such as oils, grease, and fat, disposable diapers, tampons and their holders, condoms, paper towels, facial tissues, cat box litter, plastics, cigarette filters, coffee grounds, egg shells, and other kitchen wastes, should never be put into the septic system. You should also avoid the use of in-sink garbage disposal units (“garburators”) unless the septic tank and leaching bed are designed to accommodate the increase water and organic load created from these devices
