Every listing begins as a public Google business record filed under septic system service.
Open businesses with at least one review and a record updated in the past year stay. Duplicates are merged.
Each company's own site is read for pumping, installation, inspections and the rest. The work it names is marked.
If the site says nothing about a service, the listing shows "not enough info", never a guess.
Google files plumbers, excavators and landscapers under septic system service too. We kept the ones whose own websites describe septic work and left out the ones that do not, so a plumbing franchise with one septic line on its menu does not crowd out the local pumper.
Membership in the Ontario Onsite Wastewater Association is checked against the association's own member directory and shown only when the company is listed there. Licences, BCIN registrations and insurance are shown as each company states them. We do not verify them, so ask.
Owners can claim a listing to correct details or add photos. A person checks every claim. Published by Trevor Tynes.
For a typical three or four bedroom house, plan on about $15,000 to $30,000 for a conventional in-ground system, $20,000 to $40,000 for a fully raised one, and $25,000 to $50,000 for an advanced treatment system, plus a permit of roughly $500 to $1,000. Those ranges come from the Ontario Rural Wastewater Centre, last updated in March 2023, so treat them as a floor. If that number is a lot to take in, you're not alone, and it isn't random: your soil, your house and your access decide most of it.
Tight clay, fast gravel, a high water table or bedrock near the surface all push the design toward a bigger or raised bed, because Part 8 of the Building Code needs 900 mm between the bottom of the bed and the groundwater. More bedrooms and bathrooms mean more bed. Then come the trucking distance for sand and stone, whether the system needs a pump, and how easily a machine can reach the site. On a wet or stony lot, an advanced treatment unit can cost less than building up a conventional bed.
Every new, replacement or repaired system needs a permit and inspections from your local authority: your municipality, health unit or conservation authority. If you're not sure which, call the office where you pay your property taxes. Designers and installers must be registered with the province, and their registration starts with a Building Code Identification Number, or BCIN. Ask every company for it.
The tiles on each listing show the work a company describes on its own website: pumping, new installation, bed repair, inspections, design and permits, advanced treatment, maintenance programs and emergency service. "Not enough info" means the site didn't say either way, often because there's no website. That's not a no, it's a question for the phone. The OOWA mark means the company appears in the Ontario Onsite Wastewater Association's member directory. Ratings come from Google, and a 4.9 from 200 reviews tells you more than a 5.0 from three.
A well-maintained conventional system lasts 20 to 25 years. The province's SepticSmart guide says to have the tank inspected every three to five years, pump it when a third of it is sludge and scum, and clean the effluent filter every year. A pump-out averages about $300. Treatment units also carry a yearly maintenance contract.
Who does the design, and what's your BCIN? Who applies for the permit? Is the tank, the bed, the fill and the trucking in the price? Does it cover removing the old system and putting the yard back? Get two or three quotes for the same scope, or describe your job once in a quote request and we'll pass it to companies that work your area. The full guide to septic installation costs in Ontario has the repair prices, the 2026 rule changes and more.
Ontario's SepticSmart guide says a licensed hauler or septic professional should open and inspect the tank every three to five years, and pump it when about a third of its depth is sludge and scum. The effluent filter, if the tank has one, should be checked and cleaned every year.
Yes. Installing, repairing, upgrading or replacing a septic system needs a permit and an inspection from your local regulatory authority under the Ontario Building Code. That may be your municipality, your health unit or your conservation authority, depending on where the property is.
A BCIN is a Building Code Identification Number. Septic installers and system designers in Ontario must be qualified and registered by the Ministry of Municipal Affairs and Housing, and the BCIN is part of that registration. Ask the company for it before work starts.
It means the company appears in the member directory of the Ontario Onsite Wastewater Association, the industry group for septic designers, installers and service companies. We check it against the association's own directory. Membership is not a licence.
Advanced treatment units need a maintenance contract with an authorized representative of the unit's manufacturer, and the contract sets the inspection schedule. Look for companies marked for advanced or tertiary treatment, then ask which brands they service.
Every listing starts from a public Google business record. We keep companies that are open and reviewed, read each one's website for the septic work it does, and leave out trades that list septic without doing it. A basic listing is free. Paid placements are always marked as featured.
