Winnipeg’s Sewage Treatment Program Upgrades - Funding

Millions of litres of sewage travel through a vast network of sewer pipes to the City’s three plants to be treated before being released to the Assiniboine and Red Rivers, which merge and flow into Lake Winnipeg.

We operate the three sewage treatment plants under Environment Act Licences issued by Manitoba Conservation and Water Stewardship. The licence requirements are becoming more stringent with the Province’s Lake Winnipeg Action Plan, designed to help protect Lake Winnipeg.

As a result of the new regulations, we must invest close to $1.2 billion to upgrade our sewage treatment plants, including Biosolids treatment.

Our first priority in complying with our Environment Act licence requirements is to reduce nutrients (phosphorus and nitrogen). Even though only a small proportion of the nutrients in Lake Winnipeg come from our wastewater, the new standards require that we reduce them even more.

The biological nutrient removal upgrades will reduce our total annual contributions to Lake Winnipeg.

Biosolids Management Program

Project description: Develop and implement a plan to manage biosolids in an environmentally sound, sustainable manner, while meeting Provincial regulations
Status:
  • A 30-year Biosolids Master Plan was approved by the Province March 10, 2016
  • Pilot Biosolids Composting Program initiated May 2015

City funding: $38.95 million

Funding

  • The total estimated cost for the upgrades excluding Biosolids Master Plan: $1,216.19 million.
  • Other levels of government are contributing up to 23.7% of the upgrade costs:
    • $42 million from the Federal government,
    • $40 million from the Provincial government, indicating an additional $195 million contribution, $11 million of the $206 million in a 2007 throne speech, has been allocated in the Green Infrastructure Agreement.
  • Remaining 76.3% of the capital costs are currently proposed to be funded by City of Winnipeg water and sewer rate payers.

* Costs for the completed projects are based on actual expenses. Costs for projects underway are based on the best information at this time and the 2017 approved capital budget.
