Registrant Directory

ASTTBC Registered Onsite Wastewater Practitioners (ROWP) perform maintenance, inspection, design, and installation of onsite wastewater systems. BC Ministry of Health’s Sewerage System Regulation (SSR) stipulates that only Authorized Persons (or an owner supervised by an Authorized Person) may construct or maintain onsite sewage treatment and dispersal systems.

The scope of practice for ROWPs is defined by four endorsements: Planner; Installer; Maintenance Provider; and Private Inspector. ROWPs must be registered with one or more endorsements.

• ROWP Planners (PL)
  are responsible for the assessment of site and soil conditions, system design, construction review, and certification of system construction. Individuals that are registered as a Planner are also permitted to perform private inspections without the requirement of the Private Inspector endorsement.
• ROWP Installers (IN)
  are responsible for the physical installation and repair of onsite wastewater systems in accordance with specifications provided by a ROWP Planner or a Professional as defined in the Sewerage System Regulation.
• ROWP Maintenance Providers (MP)
  are responsible for the maintenance of onsite wastewater systems in accordance with the maintenance plan provided by a ROWP Planner or a Professional. Individuals that are registered as a Maintenance Providers are also permitted to perform private inspections without the requirement of the Private Inspector endorsement.
• ROWP Private Inspectors-Residential (PIR) and ROWP Private Inspectors-Commercial (PIC)
  are responsible for the assessment of existing systems – typically to support real estate transactions or building permit applications. ROWP Private Inspectors-Residential (PIR) inspect sewerage systems on residential properties whereas ROWP Private Inspectors-Commercial (PIC) inspect sewerage systems on commercial properties. Individuals that are registered as a Planner or Maintenance Provider are also permitted to perform private inspections without the requirement of the Private Inspector endorsements.
