Why choose Delta Group for Water service connections to city mains
The anatomy of Water service connections to city mains
- At its simplest, Water service connections to city mains link the municipal distribution main (usually located beneath the roadway) to a private or public service line that feeds a building or campus. Key components include:
- Corporation stop – valve tapped into the pressurised main
- Service saddle – reinforces and seals the main at the tap point
- Copper or HDPE service lateral – conveys water to the property line
- Curb stop & box – isolation valve at the right-of-way for maintenance
- Meter pit or chamber – houses flow metering and back-flow prevention
- Building control valve – final shut-off before entering the structure
Professionally engineered Water service connections to city mains must balance flow demand, pressure zoning, pipe diameter, corrosion resistance, and cross-connection protection.
Regulatory landscape and permitting in Ontario
Every municipality enforces bylaws and design standards that govern Water service connections to city mains. Key considerations include:
| Regulatory item | Typical requirement | Delta Group advantage |
|---|
| Municipal consent | Detailed drawings, traffic-control plan | In-house permit specialists |
| Ontario Building Code | Back-flow prevention & metering specs | Certified cross-connection surveyors |
| Drinking Water Quality Management Standard (DWQMS) | Material approvals & disinfecting procedures | AWWA-compliant chlorination & flushing |
| TSSA & ESA | Separation from gas and electric plant | Utility-locate coordination teams |
| Environmental Regulations | Contaminated-soils management | Licensed hauling & disposal chain-of-custody |
Navigating these layers is integral to timely Water service connections to city mains.
Step-by-step connection process
- Desk-top utility locates: review as-built drawings and GIS.
- Field locates & daylighting: vacuum-excavate to expose existing mains.
- Traffic & pedestrian control: implement MOT-compliant set-up.
- Main tapping: install corporation stop or tapping sleeve under pressure.
- Service lateral installation: trench or trenchless pull of copper/HDPE.
- Curb stop placement: align with property line, set rod & cap.
- Pressure test and disinfection: AWWA C651 chlorination, sampling.
- Meter & back-flow assembly: coordinated with plumbing contractor.
- Surface restoration: reinstate asphalt, concrete, landscaping.
- Record drawings & turnover package: GIS-ready data for municipal asset management.
Our crews perform hundreds of Water service connections to city mains each year following this rigorous sequence.

Case study: fast-track connection in Mississauga
Project: 25-storey mixed-use tower needing dual 150 mm domestic and 200 mm fire service Water service connections to city mains on Hurontario St.
- Schedule: four-day traffic-permit window
- Constraints: 1.2 m depth hydro duct bank above the 300 mm watermain
- Solution: overnight hydro-vac daylighting, custom vertical spool fittings, and prefabricated back-flow vault craned into place.
Outcome: Zero service interruptions, full commissioning in 72 hours—earning commendation from the City of Mississauga’s Water Division.
Frequently asked questions
Q1. How long does a standard 25 mm residential connection take?
Usually one working day, including reinstatement, assuming locates and permits are in hand
Q2. What size of Water service connections to city mains require fire-flushing?
Municipalities typically mandate flushing for services ≥100 mm; Delta Group provides tanker support.
Q3. Can you upsize an existing service without road cuts?
Yes—using pipe-bursting or slip-lining we can install new HDPE inside abandoned laterals, avoiding full-width asphalt removal.
Q4. Do you handle contaminated soil?
Absolutely. Our environmental team tests, profiles, and disposes material per MECP regulations.
