DAIN CITY FORCEMAIN

DAIN CITY FORCEMAIN EMERGENCY REPLACEMENT WITHIN CITY OF WELLAND (NIAGARA REGION)

This project involved the replacement of the existing 3.1km AC forcemain from Dain City Pump Station to Gordon Street. KTH was retained by the Niagara Region, under emergency status due to breaks and blockages, to carry out the design and oversee the temporary and permanent replacement of the forcemain. KTH expedited full survey and design approximately 4km in length for the permanent forcemain construction. Tasks included dealing with all relevant agencies and gathering all required approvals and permits (SLSMC, City of Welland, MTO, Gio Railway, MECP, NPCA. The design included a bridge crossing over the tunnel cut involving the forcemain being hung off the bridge itself by hangers and utilizing an insulated forcemain pipe. The design also included a combination of by-pass, isolation, and air valve chamber design. Trenchless installation techniques such as laser guided boring for railway crossings, jack and bore installation for the MTO intersection crossing, as well as horizontal directional drilling installation were utilized on the project.

  • Phase 4B – New 300mm dia. FM – Canal Street Bridge To East End of 65 Canal Bank Easement – Completion July 2024 – $1,495,000.00
  • Phase 5 – New 675mm Gravity Sewer – Humberstone Right-of-Way Easterly to Southworth Ave. and Northerly to Gordon Street – Completion – March 2023 – $ 3,720,704.19

COLLIER ROAD – TRUNK WATERMAIN REPLACEMENT WITHIN THE CITY OF THOROLD (NIAGARA REGION)

This 450mm to 600mm diameter watermain is located on Collier Road between St. Davidโ€™s Road and Beaverdams Road, continues easterly along Beaverdams Road for approximately 550m where it turns south and crosses under the Welland Canal.

The Niagara Region indentified the need to replace the remainder of this deteriorating watermain. In 2011, Kerry T. Howe Engineering Ltd. (KTH) was retained by the Region of Niagara to design and oversee the replacement of this watermain.

KTH was required to design the new watermain that spanned from the intersection of Collier Road and Richmond Street, to Beaverdams Road, and eventually terminates near the City of Thorold Public works yard over 2 km away. KTH was responsible to deliver an engineered design, construction estimate, tender package and oversee the tendering process and administer the construction of this watermain. Given the location of the watermain, it was necessary to closely coordinate with the Ministry of Transportation as the new watermain would be passing directly under the Hwy 58 / Collier Road overpass. The design of the new watermain also had to account for the various pressure zones within the water distribution system. If this watermain was isolated from the Thorold South Water Tower, a surge in pressure would occur within the system that could potentially break watermains throughout Thorold. A final unique design criteria that was required was the use of steel water valve chambers. In an effort to increase life span and reduce maintenance costs within their subterranean water chambers, the Regional of Niagara wanted to explore the option of using steel valve chambers instead of the more common concrete chambers. This is a very new technology and would be one of the first projects in Ontario of its kind. It was also the first time that a chamber of this design would be used within a roadway.

Kerry T. Howe Engineering Ltd. completed the design in 2012 and the project was awarded to Provincial Construction (Niagara Falls) Ltd. Construction commenced in November 2012. The project was broken into 2 separate phases as the MTO had intended to do some bridge rehabilitation on the Hwy 58 overpass which would conflict with the watermain installation. By phasing the construction, the watermain could be installed beneath the overpass in time for the MTO work, after which the remainder of the watermain could be installed. The construction was completed in August of 2014 at a cost of $2.79 Million. Three steel valve chambers were installed and will serve as a pilot project for the Regional Municipality of Niagara to assess their performance and viability in future watermain projects.
