Sump Pump Inspection Program

The Township of Selwyn's Sump Pump Inspection Program provides homeowners in the Village of Lakefield with the opportunity to schedule an inspection with a specialist to verify that the residential sump pump is appropriately connected to a drainage system and not to the sanitary sewage system.

The inspector will work with homeowners to ensure proper sump pump installation and provide recommended solutions for suitable connections, if required.

In addition to the inspection, there will be an opportunity to review best practices in water and wastewater with the inspector including:

  • A property walk around to ensure proper extension of downspouts away from the home's foundation
  • Discussing best practices for water conservation and the Township regulations on lawn watering 
  • Reviewing the clean-out location of the sanitary service within the home
  • Exploring the location of incoming water services and related turn off valves

To schedule an inspection, contact Alex Ernst, Project Coordinator - Water & Sewer at 705-292-9507 ext. 225 or email Please specify your full name, address and preferred inspection time.

Frequently Asked Questions (FAQs)
 What is a Residential Sump Pump?

A sump pump is a small pump installed in the lowest part of a basement or crawlspace. Usually, sump pumps are installed in specially constructed sump pits. Ground water flows into the sump pit through drains or by natural water migration through the soil. The sump pump's job is to pump the water out of the pit and away from the building so that the basement or crawlspace stays dry and to prevent it from flooding.

 What Happens During an Inspection?

An inspection for a typical home will usually be completed in less than one hour. The inspector will walk around the exterior of the house looking at the discharge points for downspouts and area drains, such as yard, patio, window well, driveway or stairwell drains. He will also look in basement areas or crawl spaces to identify the sump pump and its point of discharge. 

 How do I Prepare for an Inspection?
The only preparation needed for the inspection is to make sure that the sump pump is accessible for the inspector, please clear a path if needed.
 What is the Inspector Looking For?
The inspector is looking for improper connections to the sanitary sewer system. An improper connection is defined as a connection that allows for clear water to be discharged directly into the separate sanitary sewer system. Clear water should either be going to the storm sewer or be allowed to soak into the ground without entering the sanitary sewer.
 What Happens After the Inspection?
Depending on the result of the inspection, nothing may need to be done. If the inspector determines that there are improper connections and drainage, he will work with the home owner to provide a list of solutions. A second inspection may be booked if necessary. 
 How do I Book an Inspection?

What Not to Flush! 
Wastewater treatment equipment is designed for toilet paper and human waste. Items like fats, oils, greases, feminine hygiene products, and wipes of any kind should never be flushed down the toilet or poured down a drain. Flushing these items causes equipment to fail, poses a health and safety risk to staff – and can even put your home at risk of sewage back-ups.
Protect Your Pipes
  • Use toilet tissue mist that adds moisture to toilet paper and can be used instead of personal wipes. Wipes clog pipes, and should never be flushed, even if the packaging says you can.
  • Use a washable microfibre e-cloth, which can be used instead of disposable cleaning wipes.
  • Use reusable baby wipes that can be washed and dried.
  • Use menstrual cups or washable cloth menstrual pads, which are environmentally-friendly alternatives to feminine hygiene products. Never flush any feminine hygiene product or its packaging.
  • Keep cooking fats, oils and greases (FOG) out of the drain. Food scraps, butter, cooking oil, soups and sauces are all types of FOG. When poured down the drain, they solidify and build-up inside plumbing pipes and can create a sewer back-up in your home.
  • Use a hair trap for your shower and bathroom sink that can capture hair that otherwise clogs your plumbing and gets caught in lift-station pumps.
  • Other top clog offenders that should never be flushed include paper towels, rags, dental floss and hypodermic needles.
