THE ONSITE WASTEWATER REGISTRATION PROGRAM
On May 31, 2005, major changes to onsite sewage systems occurred with the introduction of the Sewerage System Regulation (SSR) by the BC Ministry of Health.
The SSR signaled a change of role for government, in particular for the Health Authorities, with a new professional oversight role being assigned to the Applied Science Technologists and Technicians of British Columbia (ASTTBC).
Under the regulation, an industry practitioner must now be registered with “…a registration certificate issued by the Applied Science Technologists and Technicians of British Columbia that certifies that the holder is competent to construct and maintain a sewerage system that uses a treatment method classified as Type 1 or Type 2.” Certified practitioners are known as Registered Onsite Wastewater Practitioners (ROWP).
To meet the requirements of the SSR, ASTTBC established three categories of registration for a ROWP: Planner, Installer and Maintenance Provider. Depending on the information provided by an applicant, one or more ‘practice restrictions’ could be imposed where insufficient experience and/or training was identified. These may limit the type or style of onsite system a ROWP may work on within a given category. For example, a Planner may be restricted from planning pressure distribution systems if there experience is only with lagoons or gravity dispersal systems.

ASTTBC also registers ROWPs as Private Inspectors, a category not currently required under the SSR. As with the other categories, registration as a Private Inspector helps reassure customers that a practitioner is working to a defined standard of practice as established by ASTTBC. Inspection standards can be found within the Documents section of this website.

ASTTBC also registers Onsite Wastewater Trainees. An applicant may be registered as a Trainee if a portion of the requirements for becoming a ROWP were not met, such as insufficient practical experience.

 
Do I need to become a Registered Onsite Wastewater Practitioner?
If you do the following work within British Columbia, you must become a ROWP or a Professional:
Plan/design onsite wastewater systems including sewage lagoons but excluding industrial work camp systems and holding tanks
Install onsite wastewater systems including sewage lagoons but excluding industrial work camp systems and holding tanks
Maintain onsite wastewater systems including sewage lagoons but excluding industrial work camp systems and holding tanks installed after May 31, 2005. Anyone may maintain an onsite system installed before that date.
An Applied Science Technologist (AScT) or a Certified Technician (CTech) who wishes to offer onsite wastewater services
If you fall within one or more of
these categories, check out the Become a ROWP section of this website
