Trenchless Sewer Rehabilitation

case study: the Romeo Arch Storm Sewer

The City of Stratford’s Infrastructure & Development Services Department is responsible for the operation, maintenance, and overall rehabilitation planning of municipal infrastructure assets, including storm and wastewater collection systems. In June 2019, The City retained (A.E) to provide detailed design and contract administration services for the rehabilitation of the Romeo Arch Storm Sewer.

The Romeo Arch Storm Sewer was constructed in the early 1900s and services approximately 1,450 residential, commercial, and industrial upstream addresses. A.E’s scope included the portion of sewer that flows beneath the Avon Theatre between Downie St. and Waterloo St.

The assignment included the following activities:

  • Follow-up confined-space-entry investigation and 3D scanning of the sewer
  • Identification and development of rehabilitation options for a 109 m long, predominantly arch-shaped sewer comprising numerous cross-sectional changes with varying dimensions and construction materials
  • Preparation of detailed cost estimates, design reports, construction drawings, and contract specifications for the rehabilitation works
  • Providing tendering, contract administration, and site inspection services
