About COTRA

Technical Resource

COTRA is a not for profit technical think tank for onsite sewerage system issues.

We are independent of any other stakeholder organization, and are apolitical. Our focus is on onsite sewerage systems with ground discharge (dispersal) of effluent, both large and small systems.

We hope to be a useful resource for all stakeholders in the onsite industry-including regulators. We offer our services without prejudice to all organizations involved in the onsite field.

Currently we are focusing on technical discussion relevant to BC, but plan to expand our involvement (and our membership) to address technical issues relevant to onsite wastewater stakeholders across Canada.

COTRA is committed to furthering and fostering the adoption of performance based management of onsite wastewater systems in Canada, including performance based regulation.
