ENG-TECH provided complete engineering services for this project, which included holding public meetings with the LSB, assisting with grant application, obtaining all necessary permits, survey, design, contract specifications and tender documents, tender and awarded to Moncrief Construction Ltd and resident engineering during construction. The new and expanded community water distribution system replaced the cast iron Canadian National Railway (CNR) pipeline which was installed at the turn of the century.
ENG-TECH’s designed incorporated a 3,400 lineal meter HPDE DR17 mainline ranging in diameters of 400 mm to 150 mm. A 200 mm steel casing pipe was bored under the CNR railway for insertion of the mainline. The mainline was also directional drilled beneath the Black River. Four mainline shutoff valves, fire hydrants, miscellaneous valving such as Air Release and Blow off valves were installed on the mainline. Lateral lines serviced 48 residential and commercial services requiring curb stops and direct connection to the property owner. This water distribution system was installed by a combination of directional drilling and trenching due to the shallow depth of bedrock in some areas. In areas where pipeline cover was minimal due to bedrock, insulated HPDE was installed. Temporary water supply hook ups were provided to property owners during the construction phase of this project. The distribution system will be pressure tested and commissioned this fall.
ENG-TECH conducted inspections, contract administration and project management services throughout the project on behalf of the landowner to ensure that the contractor built the project according to the specifications. At the completion of the project, ENG-TECH prepared as-built drawings.
To date, landowners are pleased with the project due to minimal disruption of service and minimal impact to property. The project is coming in on budget and on schedule.
