Regulation respecting municipal wastewater
The Regulation respecting municipal wastewater treatment works allows municipal wastewater treatment efforts to be carried out in order to restore healthy watercourses for the people of Québec. It paves the way for major work to modernize wastewater treatment plants throughout Québec.
The Regulation is pursuant to the endorsement of the Canada-wide
Strategy for the Management of Municipal Wastewater Effluent by the Canadian
Council of Ministers of the Environment.
- Defines the content of the depollution attestations that municipalities will need to obtain for each of their wastewater treatment works;
- Incorporates the general requirements of the Canada-wide
- Provides an opportunity to sign a bilateral agreement
with the federal government to exempt Québec from enforcing
the federal Wastewater Systems Effluent Regulations that
also stem from the Canada-wide Strategy. This agreement will
be based on Québec’s jurisdiction over municipal affairs and
will put an end to the current duplication by ensuring that
only the Québec regulation is enforced in Québec.
- Made it possible to conclude a bilateral agreement with the federal government to exempt Québec from the application of the federal Wastewater Systems Effluent Regulations that also stem from the Canada-wide Strategy. This agreement ensures that only the Québec regulation applies in Québec.
The Regulation in brief
- Target clientele: Québec municipalities with sewage treatment works, with
the exception of municipalities whose facilities have an average annual flow
of less than 10 m3/day or that are located north of the 54th
parallel degree of north latitude.
- Requirements and mechanisms contained in the regulation: effluent discharge standards and standards regarding untreated wastewater overflows, monitoring of discharges, overflows and diversions, mandatory certification of treatment plant operators and a depollution attestation to be renewed at least every 10 years for each municipal treatment plant.
- Upgrading deadline: municipalities that are currently unable to meet the
regulation’s discharge standards will have until December 31, 2020, 2030 or
2040 to make their sanitation facilities comply with the new discharge
standards, depending on the environmental risk they represent.
- Anticipated benefits: protection of drinking water sources and aquatic
ecosystems, reduction of pollutants and overflow episodes, preservation or
recovery of certain recreational uses (e.g., swimming and fishing).
