WCOWMA was incorporated in 2008 with the mission to protect the health and safety of all Western Canadians by improving the training, certification and practices within the private sewage industry.


With the increase in population density, changing government regulations and new technology, the installers of onsite sewage disposal systems have increasingly felt a need to address industry concerns. These concerns include training, representation to government at all levels, and the preservation of the environment.

The Association, under the direction of its provincial chapters offers a program of training which is recognized across Canada as meeting or exceeding the requirements of the Agreement on Internal Trade and the Trade, Investment and Labour Mobility Agreement.

WCOWMA members focus on strengthening and shaping the onsite wastewater industry through their role as important stewards of the environment and key players in rural land use planning.

Key Activities

  • Influencing federal, provincial and municipal regulations
    • WCOWMA administration represents all members by participating in and sitting on a variety of committees and boards both provincially and nationally.
  • Setting the national standard for onsite training. The WCOWMA training program is recognized throughout Canada as the premier onsite wastewater certification program.
  • Influencing land use planning in Western Canada. The WCOWMA administration consults with various provincial and municipal agencies, providing information on onsite wastewater technologies and resources to help them build effective and sustainable wastewater treatment and disposal policies.
  • Spearheading onsite system research and development. The WCOWMA is currently participating in researching the new design for At-Grades through its Alberta chapter, the AOWMA.
  • Public education and consultation. A key component of having a healthy and effective onsite industry is ensuring that homeowners have access to the information they need to make sound decisions regarding their onsite wastewater systems. The WCOWMA provides that information to the general public, acting as a resource and providing referrals to our member professionals.
  • Holding industry information and networking sessions. Throughout the year, the WCOWMA participates in information sessions throughout Western Canada giving onsite wastewater professionals an opportunity to provide input and discuss concerns about these and other industry issues firsthand and face-to-face. In 2009/10 the WCOWMA will continue these regional and provincial meetings in order to continue to maintain open lines of communication with our membership.
  • Quarterly newsletters are emailed or mailed out, keeping members abreast with advancements in the onsite industry.
  • WCOWMA will launch the first publication of its semi-annual industry magazine in December 2009.

On the business front members can benefit from:
