ABCs of Sewer Connection

To assist King City’s property owners navigate the process of connecting their homes/businesses to the sanitary sewer, we’ve compiled the ABCs of sewer connection, which will answer some of your questions or, at the very least, point you in the right direction.
The King City sanitary servicing project is being phased in over a number of contracts through 2008. For information on the timing for your property, please contact the Township of King Operations Department at 905-833-5321.
General Information

What should I consider when determining the location of the sewer connection at the property line?
1. The shortest distance from where the building drain exits the building
2. Proximity to the municipal water service and other buried services (if applicable)
3. Account for existing landscaping features i.e. mature trees, etc
4. If possible, avoid crossing driveways

What are my connection options?
1. Open trench construction preferred (ball test of the installed building sewer)
2. Directional boring (ball test, video inspection of the installed building sewer and in some cases, a water flow test)
3. Grinder pump and forcemain (select properties only). Grinder pumps are used only when the property being serviced is lower than the sewer connection at the property line

If I choose to bring the pipe around the back of my home to connect where the septic system currently exists, what will the contractor need to do? What should I ask?
1. Contractor will excavate a trench from the back of the building to the connection point at the property line, the depth of which depends upon the sewer connection depth and the slope of the building sewer
2. The building drain and sewer (100 mm diameter pipe) will have a minimum and maximum slope of two per cent and four per cent respectively.
3. Cleanouts (100 mm diameter pipe) brought to grade, will be required every 15 metres of building sewer. A cleanout is an access point for snaking, should the building sewer require cleaning.
4. Cleanout at municipal connection (and all outside cleanouts) brought to grade
5. Ask for a price for all work – including the cost of decommissioning the septic tank

If I choose directional boring, what will the contractor need to do and what should I ask?
1. The contractor will bore a small diameter tunnel from the property line to the building. If connecting at the existing septic/drains, the boring will continue under the building to the connection at the back
2. If connecting in the basement, the boring will continue from the property line to the closest interior point to access the building drain. Likely, a hole will have to be dug in the basement and/or outside the foundation wall to connect the bored pipe to the building drain
3. The building drain and sewer (125 mm diameter pipe) will have a minimum slope of one per cent
4. Ask for a price for all work – including the cost of decommissioning the septic tank

Septic Tank Decommissioning:
1. Arrange for a licensed sewage hauler to pump the tank dry and retain a copy of the receipt for services received
2. The building drain is disconnected from the dwelling and sealed at the tank
3. Holes are punched into the bottom of the concrete/plastic tank to ensure drainage and the top crushed into the tank, which is then filled with an acceptable granular material such as sand or native soil. Soil should be compacted to prevent settlement
4. Steel tanks are to be crushed

Any tanks and/or leaching bed components excavated and removed must be disposed of appropriately.

What kind of contractor is needed?
1. Plumbing in the basement, if not completed by the homeowner, will require a licensed plumber and drain work will require the sills of a master drain layer
2. Contact the Township’s Building Department for an abridged list of contractors, or to receive a comprehensive copy of The Regional Municipality of York’s Drain Contractor Registry Program List for approved drain contractors and master drain layers
3. If the property owner decides to install his/her own drains, staff must be notified at time of application

What are the safety considerations?
All installations shall be carried out in a professional manner
2. All work will be subject to the “Occupational Health and Safety Act and Regulations for Construction Projects.” If unsafe working conditions are found at the time of inspection, the work will be stopped and the inspection will not be completed. The Ontario Ministry of Labour will be contacted and advised of the unsafe working conditions

What permits are required?
1. Permit to Connect – there is no fee for the Permit to Connect
2. Plumbing/Drain Permit – must be obtained from the Building Department following issuance of the “Permit to Connect.” There will be a $100 fee for the Plumbing/Drain Permit. Inspections must be called for as per the instructions that will be provided with the permit
3. Septic Tank Decommissioning Permit - $100
4. The Regional Municipality of York Occupancy Permit – For those properties on Regional roads – Keele Street and King Road, a Regional Road Occupancy Permit is required. There is no fee for this permit. For information about this permit, please call 905-895-2744 ext 5207 or 5242.

How do I obtain a permit?
1. Construction Permits - apply for construction permits at the Township of King Building Department
2. The Regional Municipality of York Occupancy Permit - call 905-895-2744 ext 5207 or 5242

No plumbing or drain shall be put into use until it has been inspected and found to conform to Ontario Building Code, Part 7, Plumbing. For further information, contact the Township’s Building Department at 905 833-4013.
What information is needed for a construction permit?
1. Property description, property owner, contractor information, drain layout sketch

Contractor Specifications:
What building material is acceptable?
1. The sewer pope must have a minimum nominal diameter of 4” (100 mm). Underground sewer pipes are usually PVC or ABS. All PVC lengths of pipes and fittings must be stamped with CAN/CSA-B182.1, Plastic Drain and Sewer Pipe and Fitting. All ABS lengths of pipes and fittings must be stamped with CAN/CSA-B181.1 “Plastic Drain and Sewer Pipe and Fitting”
2. The markings indicate the pipe material meets the minimum standards of the Ontario Building Code. Solvents or glue used for joints in the pipe are specific to the material used. PVC solvent must meet CAN/CSA-B181.2 and ABS requires solvent standard CAN/CSA-B181.1. Check with the supplier before purchasing
3. The type of pipe used in directional boring applications will generally be high density polyethylene pipe (HDPE). Directional boring contractors must supply proposed pipe specification to the Township’s Building Department prior to installation and comply with the requirements as set out above

What are the typical installation techniques for the building drains?
1. Base support: Underground pipe must be supported on a base that is firm and continuous under the entire length of the pipe. All building sewer pipe must be supported to prevent sagging. A compacted depth of 6” (150mm) is generally sufficient bedding thickness. Crushed ¾” (19mm) clear stone provides good support that does not require compaction and provides protection for the pipe prior to backfill.
2. Slope: The pipe slope should be at least two per cent slope (1/4” per foot or 1:50 and directed away from the building and toward the municipal sewers
3. Cleanouts: Every sanitary building drain must have a cleanout that is located as close as possible to the place where the drain leaves the building or can be located outside the building to facilitate access.
