S-103.1 Why MKC
Why choose MKC for wastewater management
Wastewater problems usually surface as a backup, a fine or a failed inspection. Toronto’s Sewers By-law, for example, requires food service establishments to install and maintain grease interceptors, and premises where vehicles are repaired or serviced to have oil interceptors. MKC’s engineers design to the by-law and the Building Code, the installation is part of the same contract, and we help you set up the maintenance schedule the by-law expects.
Design, build and compliance
Engineering, excavation and installation sit in one contract, and you receive the drawings, test reports and maintenance schedule that an inspector or the City may ask to see.

S-103.3 Budget & schedule
What affects
the price
Every estimate is built from your measurements and choices. These are the things that move the number most.
An indoor interceptor or backflow device can often be installed in a day or two, while sewer connections and on-site sewage systems take longer. Permits, what the excavation uncovers and the weather decide the rest.
Every project is different, so your estimate comes with its own written schedule, and we aim to beat the usual industry timeline on every job.
- 01Device type and size
Interceptor and backflow device sizes follow flow rates, fixtures and the property’s hazard level.
- 02Location and access
Indoor installs under slabs need cutting and restoration, and outdoor ones need excavation.
- 03Excavation depth
Deep sewer connections and poor soil need shoring and more restoration.
- 04Permits and testing
Most installations need a building permit, and backflow devices need a test report.
- 05Restoration
Repaving, concrete and landscaping after excavation add to the final cost.

S-103.4 Questions
Questions about wastewater management
Don’t see your question? Call (647) 637-6052 or ask in your estimate request.
How often does a grease interceptor need servicing in Toronto?
A grease trap must be emptied completely, cleaned and inspected every four weeks, or sooner if fats, oils, grease and solids reach 25 per cent of its liquid volume or its rated capacity. The City may allow up to eight weeks if your records show low build-up. Not having a working interceptor can lead to fines of up to $100,000. We install and size interceptors to keep servicing manageable.
Does our building need a backflow preventer, and how often is it tested?
In Toronto, industrial, commercial, institutional and larger residential properties must have a backflow prevention device on their water supply. Devices are tested when installed, within 72 hours of any repair or service, and at least once a year, by a certified Cross Connection Control Specialist. Peel Region also requires yearly testing. We install devices under permit and coordinate the tests.
What affects the cost of installing an interceptor?
Size and location. A small under-sink unit is a short plumbing job, while a large in-ground interceptor means cutting a slab or excavating outside, then restoring concrete or paving. Depth of the sewer connection, soil conditions and the permit add to it. Our engineers size the unit to your fixtures and flows, so you are not paying for more interceptor than you need.
Can a restaurant stay open while an interceptor is installed?
Often, yes. Small under-sink or in-floor units can be installed overnight or on a closed day. A larger in-ground interceptor means cutting the floor or excavating outside, which takes longer and may need a short closure of the kitchen. We plan the cut-in and plumbing tie-in so the kitchen is down for the shortest time the work allows.
When does a site need an engineered drainage or sewage design?
Usually when you add a connection, change flows, or build something the Building Code’s standard details do not cover, such as an on-site sewage system, storm drainage for a parking area or a large interceptor. Municipal rules also keep storm and sanitary flows apart, and in Toronto storm drainage may not be directed to a sanitary sewer. Our engineers prepare the design and permit drawings.
