Most properties are equipped with a main shut off valve that is usually located close to the water meter and used to shut off water supply during emergency or plumbing repair work. In the event the valve needs it be fixed or replaced, an appointment can be booked to have the service turned off or on at the curb. Please call Markham's Contact Centre at 905-477-5530 or email email@example.com. A fee is charged to the property owner to recover the cost of service. Please see Waterworks User Fees
If low water pressure is affecting all water fixtures in a building and you have a water softener, set it to bypass and then check your water pressure again. If your water pressure resumes while your water softener is set to by pass please contact your water softener provider. If this does not resolve the problem, please call the Contact Centre at 905-477-5530 or e-mail firstname.lastname@example.org. A Waterworks staff member may be dispatched to look into this issue.
If your water pressure is low at a single fixture, remove the faucet aerator (located at the tip of the faucet) and rinse the screen. If this does not resolve the problem, contact a plumber.
When a fire hydrant is opened, there is a large volume of water used which can stir up iron in the watermain. This causes water to be brown in colour. Cloudiness is caused when air becomes trapped in the water. This can happen when it travels through pressurized water pipelines, and the air remains trapped until it is released from your faucet. In either condition, the water is still safe to drink.
Water is tested at source treatment facilities on a regular basis. Markham Waterworks also collects and tests water samples in accordance with the Safe Drinking Water Act. Markham Annual Water Quality Report.
If the pipe to your meter is wet all along its length, this is condensation from warm, moist air coming in contact with the colder pipe and not a leak. If the tap next to the meter is leaking, this is the property owner’s responsibility to repair. Waterworks staff can shut water off while the tap is being repaired. Please call the Contact Centre at 905-477-5530 or email email@example.com. A fee is charged to the property owner to recover the cost of service.
This is your water shut-off valve (also called a curb box or curb stop valve). A curb box is a round metal plate approximately 10 cm in diameter that is located in the front lawn, driveway or sidewalk of a property and is owned by the City of Markham. Please keep this valve accessible at all times. If you are resurfacing/excavating/landscaping your driveway, or front lawn, please contact Waterworks staff to inspect the curb box prior to any work. This will ensure it remains operational.
Water hardness refers to the level of certain minerals in a water supply, typically calcium and magnesium carbonate. It has no adverse health effects. Markham’s water is considered hard at approximately 123 milligrams per litre, or 8.6 Grains per Gallon.
Sewage smell is generally caused by gas from decaying organic matter. Sewer pipes are designed to trap or direct and prevent odour from entering a building. Sewer odours may be an indication of a failing or blocked plumbing fixture. Internal plumbing is the responsibility of the property owner. Markham provides inspection services to determine if there are blockages on the City side of the service. To schedule an inspection call the Contact Centre at 905-477-5530 or email firstname.lastname@example.org.
Call the Contact Centre at 905-477-5530. Please be aware that sewer blockages that are within the property line are the responsibility of the property owner. City staff is only authorized to inspect and fix blockages on City property.
A backflow preventer is intended to prevent water from a private pressurized system flowing back to the municipal water supply system. It is installed on your water pipe. The City has a Backflow Prevention Program, which focuses on business and multi-residential properties since they have a higher probability of contaminating the municipal water supply system.
A backwater valve installation at a residential property usually occurs after the property has been built and occupied. Although it requires a Plumbing Permit to install, some may have been installed without a Permit. Therefore, the City does not have complete records in place.
However, you can do a quick check by yourself. If a backwater valve has been installed at your property, you will likely see a rectangle plastic lid on your basement floor. The backwater valve will be located underneath the lid. Regular maintance of the backwater valve is required to ensure it does not get clogged.
The installation work may include breaking up the concrete floor in your basement, cutting off your existing sewer pipe and putting in the device, reinstating the excavated area, etc. The actual cost will vary case by case. The total cost will include labor, materials, permit and taxes, etc.
Yes. Either you or your contractor must obtain a building permit for a backwater valve installation.
It is important to have our City’s building inspector to check the installation completed by your contractor. A malfunctioning or an incorrectly installed backwater valve may clog your sewage going out and result in backup of sewage into your home.
The City does not have any rebate program in place for installing a backwater valve in your home. It is the home owners’ choice to undertake such installation and the home owners’ responsibility for related costs.
1. The City does not have any combined sewer system in place (i.e. sanitary system with storm sewer system in one pipe), which is the main reason your basement may flood.
2. The City has a storm water “Downspout Disconnection Program” in place, it is mandatory for property owners to disconnect their downspouts from our sanitary sewer system. That program is intended to reduce the risk of your basement flooding and releasing roof rainwater into our local waterways.
3. The City has a Flood Control Programin place. It is a long term, City-wide initiative to improve storm drainage capacity and limit surface and basement flooding risks in urban areas.
4. The City is also raising public awareness for the proper disposal of fat, oil and grease. Sewer blockage caused by fat, oil and grease is another factor that can cause sanitary sewer backups in homes.
Look for the WaterSense label when purchasing water fixtures. WaterSense guarantees products are at least 20 percent more water efficient than average products in that category. ENERGY STAR® labels guarantee water efficiency for dishwashers and clothes washers, ensuring products have been tested and meet efficiency standards.
Markham Waterworks offers many useful tips for being water efficient, with links and videos to help you save money and use water wisely. These include the selection of water efficient fixtures and appliances, how to find and repair leaks, and how to create a water efficient landscape for your home.
Planting native species and reducing paved areas helps retain rainwater on your property, therefore requiring less water. There are many resources to help you design and transition your landscape to be more water efficient – Toronto and Region Conservation and York Region have publications on this topic.
All wastewater and storm water is eventually returned to Lake Ontario, our source of drinking water. So it is very important that hazardous materials are never poured down the toilet, sink, floor drain or storm drain. Take these materials to the Hazardous Waste Depots for safe disposal.
Markham started the Water on Wheels (WOW) program in 2011. We bring our portable water trailer to community events and festivals throughout the summer and early fall.
