Hooking Up

There are two ways your property can be connected to the sanitary sewer system. They are:

Option 1 

Open trench construction - This is the most common method.  A trench is dug from your house to the sewer connection point at your property line into which a sewer pipe is laid.

Option 2 

Directional boring - This alternative method can be used if trenching is not practical.  A machine drills a horizontal underground hole and pulls a sewer pipe through the hole.  If connecting at the existing septic system/drain, the boring may continue under the building to the septic connection.  It's likely a hole will need to be dug in the basement and/or outside the foundation wall to connect the bored pipe to the building drain.

Getting the Work Done

Below is a step-by-step guide to hooking up to the King City sanitary sewer system: 

Step 1:  A connection location form is sent to property owners to indicate the preferred location for the lateral pipe from the sanitary sewer to their property line. This step has already been completed in all Contract Areas. The Township has records of where the service pipe is located on your property and will provide that to your contractor.

Step 2:  A connection notice from the Township is sent to property owners, indicating when the sewer service is available. Property owners for all Contract Areas have already received this.

Step 3:  Contact a drain contractor. The contractor can help you decide which method of construction (open trench or directional boring) is best for your property and will obtain the necessary specifications from the Township. It's recommended that homeowners not do the installation work on their own, as it is best to have a licensed contractor do it.

Step 4:  Obtain the necessary building permits (combined Plumbing/Drain Permit and Septic Tank Decommissioning Permit). To download the permits click here or pick them up at the Township Offices and they will be processed together. In this way the total cost for the package of permits is reduced to $281.25. There is no cost for the Permit to Connect.  

Step 5:  Your contractor will decommission the septic tank. It is mandatory that tanks be properly decommissioned and not used for any other purpose. 

The tank must be pumped dry by a licensed sewage hauler and a copy of the receipt must be provided to the Township's building inspector when he comes to inspect the decommissioning. The tank must be filled with native soil or sand. The drain pipe that formerly ran through the exterior foundation wall to your septic system must be cut off flush with the wall, plugged and parged, and waterproofed on the outside of the wall. 

Helpful Tips

#1 Obtain quotes from a few different contractors for the work to be done, to ensure you are not paying too much.

#2 Ask the contractor what is included in the quotation. For example, does it include the restoration of landscaping, driveways, decommissioning of existing septic tank, etc.? 

#3  Ask contractors for references and then check them to make sure previous clients have been satisfied.

#4  It's important that your contractor verifies the elevation of the sanitary lateral pipe at the property line before starting work.  This will ensure that the connection will work all the way back to the house.

#5  Be sure to keep copies of the receipts for the work done to connect to the sanitary sewer and decommission your septic tank. 

Downspout Reminder

When your property is being connected to the sanitary sewer system, it's a good time to check how other water-bearing systems are draining, and where.

Township staff members inspecting properties have discovered downspouts that connect to foundation drains, or directly to the sanitary sewer, or sump pumps that drain to the sanitary sewer instead of to exterior ground drainage.   

These types of connections are not permitted and must be removed. Rainwater and groundwater should not be added to sewage since it greatly increases the cost to treat sewage at the plant.  

The Township will enforce the removal of any such connection.
