Stamford Interceptor Phase II Trunk Sewer
2022 Trenchless Technology Project of the Year
The primary scope of work on this project was to reline 1,560 meters of existing 1050mm diameter sanitary sewer located within an Ontario Power Generation canal along the high traffic Millennium Pedestrian Trail in the City of Niagara Falls. The work involved rehabilitation of 14 sewer segments and manholes. Four sewage pumping stations and local connections discharge in to the Stamford sewer. CCTV was used to identify corrosion in these sections. LiquiForce was responsible for developing and operating a bypass pumping system for these connections. All water used in the cure process was treated to reduce the styrene concentration prior to discharge.
Calgary Sanitary Sewer Lateral
The City of Calgary put together a lateral program to take advantage of the benefits of trenchless technology, including reduced social and environmental costs, reduced inconvenience to residents and local businesses, and a lower cost than traditional dig and replace methods. After working with engineers,
This project included approximately 512 laterals.
Cleanouts or other private property access was strictly prohibited. PFM (Prep From the Main) technology was built to avoid the use of cleanouts.
Hespeler Trunk Sanitary Sewer
The Hespeler Trunk Sanitary Sewer was constructed in the 1970s and feeds
the Hespeler Wastewater Treatment Plant. The sewer lays entirely within Grand River
Conservation Authority lands and includes an underwater crossing of the Speed
River. This project included 5,000 ft of 24-27 inch diameter vitrified clay
sewer main, 11 CIPP inversions ranging in
length from 141-686 ft, and 16 manholes
varying in depths up to 15 ft. The project included the installation of a bailey bridge for bypass purposes. All construction was
completed within 65 working
days.
South Service Road (Eastern Interceptor)
This deep sewer (30 feet), rehabilitation consisted of 435m of circular
60” 66” Trunk Sewer on the Eastern Interceptor. This line was suffering from invert damage of the entire length. In one location, localized repairs needed to be
performed to stabilize a hole in the invert that was previously identified (3 ft wide x 4
ft long x 4 5 ft deep).
The chosen repair method for this pipe was CIPP. Due to the liner weights and
thickness, this installation required two OTH CIPP inversions.
LiquiForce set up approx. 10,500 ft of 18” HDPE pipe to maintain the flows within the Eastern Interceptor.
