Wastewater and Stormwater

The Wastewater and Stormwater Committee is a group of experts on municipal wastewater and stormwater treatment. The group provided coordination for CWWA’s advocacy activities on the Wastewater Systems Effluent Regulation and continues to monitor federal activities related to wastewater and stormwater regulation. The group assists in coordinating the wastewater and stormwater sessions at the National Water and Wastewater Conference.

Recent Advocacy

Building Code
CWWA has been advocating for changes to the Ontario Building Code, in hopes that these changes will eventually be reflected in the National Building Code. Requested changes include:

  • recommending that every pipe in a drainage system, including an external leader or fixture outlet pipebe capable of withstanding without leakage a water test, air test and final test.
  • sanitary laterals should be inspected via CCTV before occupancy 
  • more presciptive requirements for backfill material to ensure lateral pipes are properly supported
  • more prescripitve requirements for private side bedding
  • every sanitary drainage system connected to a public sanitary sewer, a public combined sewer or a private sewage disposal system shall be impregnated green. This change would greatly reduce the risk of cross connection.
  • requiring gasketed joints (meeting specified standards) on plastic pipes, fittings and solvent cement 
  • storm drainage systems should be white, reducing the risk of cross connection
  • require a visual inspection of private side laterals
  • stronger inspection and testing for leakage

National Pollutant Release Inventory
CWWA sits on the NPRI Work Group on Substances and frequently comments on proposed changes to the program when it impacts the sector. 

Wastewater Systems Effluent Regulations
CWWA was very active during the development of the Regulation and continues to provide comments and advocacy for members during the implementation period.

Flushable Products

All of us in the wastewater sector understand the harmful impact that so-called flushable products have on our municipal wastewater systems. From additional maintenance, to equipment damage, to clogs and system failures to contamination of sludge, this issue is costing Canadian municipalities over $250 million each year. The inappropriate labeling of products and counter-education of our customer’s needs to be addressed. Currently, there are no standards, regulations or official definitions for the use of the term ‘flushable’. A solution is needed that supports jobs and free trade, but not at the expense of our wastewater systems. MESUG and CWWA have combined forces to address this situation for Canadian utilities, but we need your support.

The Biosolids Committee is a national advocate for the beneficial use of biosolids in Canada. The Committee is exploring means of functioning as an independent consortium within CWWA. Until a decision about the future of a national consortium are finalized the Committee is dormant.

CWWA is a non-profit national body representing the common interests of Canada’s public sector municipal water and wastewater services and their private sector suppliers and partners.
