Source Water Protection

Care and Maintenance

Find information on steps you can take to reduce threats to your source water.

Do you have a private on-site septic system?

Septic systems are considered potential threats to our drinking water sources because of the possibility of leaching of contaminants like chemicals and bacteria into ground or surface water.

Care and Maintenance Tips:

  • Be mindful of what you put into your septic system. Use septic friendly cleaning products and do not pour grease, food, paint, pesticides or toxic chemicals down your drain.
  • Know where your tank and leaching bed are located and avoid parking vehicles on or driving over your tank and leaching bed, and do not construct driveways, buildings, or pools on or near any part of the septic system. Keep trees and shrubs away from the leaching bed.
  • Have your septic tank pumped out at the appropriate frequency (generally every 3 to 5 years). Keep a record of your pump-out so you will know when to have it done again.
  • Know the signs of a failing septic system. Carry out routine surface checks of your septic system to ensure that there are no soggy areas or ‘break-outs’ of sewage on the surface of the ground.
  • Efficient water use can improve the operation of your septic system. If you have a lot of household laundry, try to spread your water usage throughout the week rather than doing multiple loads of laundry in one day.

Septic Systems Inspections

All septic systems in vulnerable areas where they are or would be significant drinking water threats are required to be inspected on a five year cycle in accordance with the Ontario Building Code and the applicable Source Protection Plan.

These mandatory inspections are carried out by the Town of Caledon.

Do you use heating oil or store fuel on your property?

The handling and storage of fuel is considered a potential threat to our drinking water sources. Fuel storage tanks may leak and spills can occur that contaminate our groundwater and surface water.

Care and Maintenance Tips:

  • Check regularly for corrosion of the storage tank
  • Ensure proper and regular maintenance of the storage tank
  • Remove unused storage tanks and fill/vent pipes
  • Consider replacing your fuel tank with a double walled or double bottomed tank and installing a drip tray alarm (on indoor tanks) if you heat your home. This will help to protect your property and drinking water sources.
  • Have the tank inspected every year by TSSA (Technical Standards and Safety Authority). For more information please visit the TSSA website
  • Ensure fuel storage tanks are located at a distance, in compliance with TSSA standards, from a drilled or a dug well, river or stream.
  • Report and address spills immediately. For more information please visit the Region of Peel’s Environmental Control

Do you have a private production well?

If you have a private well, it is your responsibility to protect and maintain the well. Unmaintained, old or unused wells on your property can become a direct pathway for pollution to contaminate groundwater.

Care and Maintenance Tips:

  • Have your active well inspected regularly by a licensed well contractor
  • Make sure your well has a proper cap to guard against potential surface contamination or vermin
  • Have your water tested regularly to detect any water quality concerns so they can be addressed
  • Have your unused well properly decommissioned by a licensed well contractor

Did you know?

If you have an old, unused private residential well you may be eligible to take advantage of a fully funded opportunity to have your well decommissioned through the Region of Peel’s Private Well Abandonment Program.

As a residential well owner it is your responsibility to keep your water source safe and secure. For more information please visit the Ministry of the Environment, Conservation and Parks website.

Do you use road salt or store large piles of snow on your property?

The application, handling and storage of road salt are considered drinking water threats. The main reason road salt is considered a threat is due to the potential for chemical runoff which can make their way into drinking water sources (both ground and surface water). The most commonly used products for de-icing on roads are sodium chloride and calcium chloride.

The storage of snow is also considered a drinking water threat under certain circumstances such as snow that is pushed into large piles on a property (stored in parking lots); or snow transported to a central site from other locations (snow disposal sites). This threat is closely linked to road salt, because snow is able to pick up the salt that has been applied to roadways.  Snow removed from roads and parking lots can be contaminated with salt, oil, grease and heavy metals from vehicles, litter and airborne pollutants.

Care and Maintenance Tips:

  • Choose a ‘green’ de-icing product or use sand or kitty litter on slippery areas
  • Apply de-icing products in the amounts and as directed on the manufacturer’s label
  • Do not apply salt when the temperature falls below -10 degrees Celsius (14 degrees Fahrenheit) as no melting will occur
  • Ensure contractors are using best management practices for snow removal and de-icing
  • Ensure snow is piled away from storm sewers, septic beds and wells
