sewage treatment


Call to action:

We need your help. Tell Manitoba’s minister of Environment and Climate Change to accelerate phosphorus compliance at Winnipeg’s north end sewage treatment plant.

Winnipeg’s North End Water Pollution Control Centre (NEWPCC) is the city’s largest sewage treatment plant and the single-largest point source of phosphorus to Lake Winnipeg

Manitoba’s government first set the conditions of NEWPCC’s operating licence in 2005 – among them, a requirement that the total phosphorus concentration in the plant’s wastewater effluent not exceed 1 mg/L. To date, NEWPCC remains non-compliant with this limit – and two provincial deadlines to achieve compliance have been missed.

Proven, cost-effective and efficient solutions to meet phosphorus limits for sewage effluent have already been implemented in jurisdictions across North America.

Together with our members, we continue to advocate for accelerated phosphorus compliance at Winnipeg’s north end sewage treatment plant as a priority infrastructure upgrade.

Second missed NEWPCC compliance deadline: Dec. 31, 2019

Our collective advocacy is having an impact.

A chemical phosphorus-reduction system based on a design first proposed by LWF and our partners in 2019 is now up and running at NEWPCC. This system uses a chemical called ferric chloride to bind to phosphorus and settle out of the liquid waste.

Early monitoring data suggest the chemical system is already outperforming projected expectations. This is a significant milestone and the single most important step the city has taken to protect Lake Winnipeg: a success made possible thanks to the tireless advocacy efforts of concerned citizens who joined us in speaking up for a practical, proven, cost-effective approach to sewage treatment.

The resulting solid waste generated by chemical phosphorus reduction requires increased biosolids digester capacity for effective treatment. A new biosolids facility at NEWPCC is the City of Winnipeg’s No. 1 infrastructure priority.

We are now urging the Manitoba’s government to use its authority as environmental regulator and take action to ensure phosphorus compliance at NEWPCC will be achieved by the province’s extended deadline of 2030.

Specifically, we are recommending that Manitoba’s government:

  • Reinforce phosphorus compliance as the primary provincial requirement for the protection of Lake Winnipeg, as articulated in Manitoba’s Water Protection Act;
  • Amend NEWPCC’s provincial operating licence to require that the provincial phosphorus limit be met through chemical phosphorus reduction as part of the new biosolids facilities project; and
  • Increase funding for biosolids facilities construction, contingent on these additional provincial funds being used to meet and sustain phosphorus compliance upon completion of these new biosolids facilities.

The provincial government has a responsibility to protect Lake Winnipeg.  We are closely monitoring progress towards phosphorus compliance at NEWPCC and will continue to hold Manitoba’s elected leaders accountable to this responsibility.

Thank you for joining us as we speak up for Lake Winnipeg. Together we are making a difference!

Manitoba’s government must take accountability for phosphorus compliance

Instead of deflecting its responsibility for achieving phosphorus compliance at Winnipeg’s largest sewage treatment plant, Manitoba’s government must take action to implement a cost-effective solution.

Advocacy success: chemical phosphorus-reduction system now operational

Thanks to the tireless advocacy of concerned citizens, chemical phosphorus reduction is now happening at Winnipeg’s north end sewage treatment plant – the single most important step the city has taken to protect Lake Winnipeg.

Phosphorus compliance requires political leadership

Manitoba Environment and Climate Change Minister Tracy Schmidt must work with her cabinet colleagues to put in place a fully funded, accelerated, evidence-based plan for phosphorus compliance at Winnipeg’s north end sewage treatment plant.
