Sewer connection overview

Connections to the municipal sanitary or storm sewer system in Oshawa typically require coordination with Development Engineering and Building Services.

  • Contact Development Engineering for sewer lateral alignment, connection point and inspection booking [3].

  • Arrange inspections after work is complete and keep records of approvals and as-built drawings for final acceptance.
Always confirm the current fee schedule and required documents with the city before starting work.
