Water Services

Potable water is supplied to residents within Morinville through a regional transmission line from EPCOR. EPCOR is responsible for the treatment of the water before transmission and they provide daily source water quality results. Our Certified Water and Wastewater Operators monitor water quality following Alberta Environment guidelines and legislation. 

Orthophosphate in water

Our region’s drinking water comes from EPCOR’s treatment plants. Starting in late March 2023, EPCOR will add orthophosphate to its water treatment process to protect customers from lead in drinking water and water pipe corrosion. While there isn’t lead in the water when it leaves the treatment plant, lead can get into the drinking water through lead pipes and other household plumbing fixtures.

Orthophosphate FAQs

What is orthophosphate?
Orthophosphate is tasteless, odourless and safe. Phosphate is naturally found in foods like bread, cheese, fruits and nuts. It’s also a common additive in beverages. Orthophosphate creates a protective barrier on plumbing surfaces to reduce the release of lead in drinking water from all sources, including lead service lines and plumbing. It is the industry standard for treating lead corrosion in municipalities all over the world and in Canada, and has been endorsed by Alberta Health Services and Alberta Environment and Parks.

Is orthophosphate safe?
Orthophosphate has been approved for use by Alberta Health. The addition of orthophosphate is regarded as the industry standard for proactively dealing with lead and is used by municipalities throughout North America, including Toronto, Winnipeg and Halifax.

Why are you adding orthophosphate to the water treatment process?
In 2019, Health Canada recognized the serious health impacts of lead by lowering the maximum allowable concentration in drinking water. When water leaves the water treatment plants, it is free from lead. However, EPCOR is adding orthophosphate to protect customers from lead that comes from other sources like lead water service lines and interior plumbing, such as valves and faucets. The lead inhibitor (orthophosphate) forms a protective coating inside water lines and on fixtures which helps prevent lead from releasing into the water that flows through the pipes.

What are the health effects related to orthophosphate?
Adding a lead inhibitor (orthophosphate) has no negative effects on health. It is naturally present in food and is a common additive to beverages. 

Why do we need to add a lead inhibitor in Morinville if very few homes have lead service lines?
Lead service lines are not the only source of lead, in-house plumbing fixtures can also be a source of lead in drinking water. Adding a lead inhibitor to the water is part of EPCOR’s comprehensive approach to minimizing the risk of lead in drinking water for Morinville and other surrounding regional customers. It also ensures drinking water meets the Health Canada guidelines for lead in drinking water.

How do people know if they have a lead service line or lead plumbing?
If your home was built before 1960, it is more likely it may have lead service lines. Homeowners can also visit epcor.com/lead to see the three-step process for finding out what material your pipes are made of.

Will businesses that use water for manufacturing purposes be affected by the addition of orthophosphate?
It is possible some high volume commercial users will need to make a change to their water processes. EPCOR has communicated with commercial customers in advance of adding orthophosphate in order to give each customer ample time to review their process with a consultant or consult their industry association. If you have not been contacted by EPCOR but still have questions, please visit epcor.com/ortho.

Preventing frozen water meters and water lines

Throughout our cold months residents may experience frozen water pipes, water meters, and service lines throughout the winter. You are responsible for protecting the water pipes, water meter, and service lines on your property from freezing.


Follow these helpful tips to prevent water outages caused by frozen water pipes, water meters, and service lines:

  1. Ensure your water meter and hot water tank are free of any clutter that could prevent warm air from other areas of the house from reaching them.
  2. Open interior doors and cabinet doors to allow heat from the house to warm unprotected pipes and water meters in cold basements and similar areas.
  3. Regularly run water through your pipes through regular daily use.
  4. Check for cold drafts in areas where supply lines are located such as basements, crawl spaces, attics, garages, and under kitchen and bathroom cabinets.
  5. Insulate hot and cold-water pipes located in cold areas.
  6. If you will be away for an extended time keep your heat on.

Shutting off water to your property

You may need to turn the water off to your house for repairs, renovations, or in the case of flooding. Each property with Town water service has a CC Valve located at the property line. The CC Valve is connected to the main water line near the street and can be shut off by our team. Please contact our Infrastructure Services office at 780-939-2590 to inquire.

Water conservation - Water restrictions and bans

Water conservation is important to everyone. Conserving water benefits our natural ecosystems, reduces energy use and can even save you money. Making simple changes around your home can significantly lower your water usage.

The sewer system collects wastewater from your home or business and transports it to the Alberta Capital Region Wastewater Commission for treatment. 

As the homeowner, you are responsible for pipes within your house and property, as well as blockages caused by anything flushed down the drain or by roots from trees within your property.

We are responsible for the pipe from your service connection (also called a water valve) on your lawn or driveway to the sewer main. Our Operators provide 24-hour response to sewer back up complaints, as well as investigation of sewer odour smell complaints and manhole concerns during business hours.

If you believe you are experiencing a sewer backup, we advise you not to flush the toilet, use any appliance that uses water to operate, or turn on any taps. Instead, contact our Team:

Monday – Friday (8:30 am – 4:00 pm): 780-939-2590

After hours – 780-965-0994

Preventing sewer issues / back ups

The town recommends the installation and maintenance of a backwater valve, which is a device that helps prevent sewage from an obstructed sewer line from flowing back through the pipes and flooding your basement. A private plumber may be hired to install a backwater valve if your home does not already have one.



  • Do not pour fat, oils, or grease down the drain. Collect and dispose of them in your organics (green) cart.
  • Do not flush wipes and other hygiene products. Even products labelled as flushable can clog pipes.
  • Take unused medications to the pharmacy for disposal rather than flushing them down the toilet. Pharmaceuticals are not treated and end up in our water environment.
  • Properly dispose of household hazardous waste. Materials such as paint, glycol and motor oils are accepted at the Household Hazardous Roundup.

Sani Dump - 9908 104 Street

The sani dump is open 24-hours a day year round, although water is only available during spring and summer months. The water is not potable and is for rinsing only.


Water has been turned off for the 2023 season.

Sanitary sewer flushing

We flush sanitary sewers annually from April to October.

The work will not affect homeowners or cause any disruption to service, although there is a possibility that small spills, noise, and odours may appear in some homes. Odours will dissipate soon after the line is flushed. Open windows to minimize the smell. Keeping toilet lids closed regularly is helpful. 

The sewer cleaning process uses a high-pressure water jet to scrub the pipe. When the water jet passes through the sewer main, the water pressure draws air through the pipes. This air movement can push out or pull in the water and air held inside your toilets, showers, sinks and floor drains. Flushing the lines removes sand, gravel, and grease from the sewer mains. This preventative maintenance operation helps to prevent sewer blockages, odour generation and premature wear of infrastructure.
