The City of Belleville is constructing a new Avonlough Sewage Pumping Station (SPS) and Conveyance System to provide municipal wastewater servicing for the development of the Loyalist West Belleville Secondary Plan major growth area.

Phase 1 of the Avonlough SPS includes the pumping station, conveyance sewers and pressure sewers interconnections and associated road reconstruction and linear infrastructure replacement. Phase 1 has been divided into two contracts for tendering and construction. Contract 1 is for the Avonlough Pumping Station and two forcemains to connect to the gravity sewer on Bridge Street West at Palmer Road. Contract 2 is for the conveyance piping along all of Bridge Street West to the existing pipe crossing of the Moira River. This advanced temporary connection on the west side of the Moira River will utilize available capacity in the Moira Pressure Sewer, allowing the City to postpone two (2) subsequent phases.


Future Construction Phasing
  1. Phase 2 will extend the Avonlough Pressure Sewer (APS) across the Moira River to the interim connection point with the existing MPS on the east side of the Moira River.
  2. Phase 3 will entail the permanent connection with the extension of the APS to the Belleville Wastewater Treatment Plant (WWTP).

Once commissioned, the Avonlough SPS will unlock development within the Loyalist West Secondary Plan Area. In total the Avonlough SPS will have capacity of 490 L/s, which will support the development of approximately 9000 units.


Planned Improvements:
  • Development of a new sewage pumping station and conveyance sewers
  • Replacement of watermain and storm sewers
  • Decommissioning and diversion of flow from the existing Avonlough SPS
  • Intersection improvement and widening at Bridge Street West and Sidney Street
  • Reconstructing Sidney Street / Catharine Street, Bridge Street West / Yeomans Street / Wellington Street intersection, Bridge Street West /Dunnet Boulevard intersections


This new, expanded infrastructure will establish sufficient capacity to provide for growth of our community.

    Notice | New utility poles will be installed along Bridge Street West between Dunnett Boulevard and Ritchie Avenue beginning next week. There will be temporary sidewalk/pathway closures while the work is completed. One sidewalk/pathway will remain open at all times. This work is expected to take approximately 4 weeks.


    This is preparatory work for the widening of Bridge Street West from Dunnett Boulevard to Ritchie Avenue, which is part of the Avonlough Sewage Pumping Station project.

    Please note that some of the new poles will be installed in the middle of the existing asphalt path on the north side of Bridge Street West. These poles will remain like this over the winter and an accessible path will be added around them.
