Standard Of Practice Update

Current Status:

At this time, there are no additional Standard of Practice updates required beyond the 2021 update.

Please stay tuned for future updates should new revisions to the Standard of Practice or additional training requirements be introduced.

Site & Soils Evaluation Field Days

Site and Soils Evaluation Field Days are offered for those interested in learning more about performing detailed site visits and designing systems for difficult situations and soils. These training workshops provide information on assessing soil structure, texture, and consistence, assessing site conditions and constraints, logging information and applying that knowledge to the design of onsite wastewater systems. This provides a valuable opportunity to gain hands-on experience evaluating a site, as well as practicing hand texturing and sampling. These field workshops are a requirement for those completing the Onsite Wastewater Practitioner Training Program and also add value for experienced designers and installers wishing to continue their education.

Dates to be Announced

Mound Installation Field Day

This practical training workshop is a great opportunity to get hands-on experience building a sand treatment mound.

Practitioners who have recently completed the Onsite Wastewater Practitioner Training Program will be able to take their new knowledge and apply it on-site. Experienced designers and installers should also consider this opportunity to continue their education.

Dates to be Announced

Install Training Field Day

Installation Field Days provide new and experienced installers with the opportunity to learn new techniques and installation practices.  Field days may be offered for systems such as subsurface trench systems either gravity or pressure distribution, LFH At-Grades, or even something as simple as an open discharge (surface discharge or jet) depending on the site and soils available and the regulatory framework.

Dates to be Announced

Maintenance Provider Practical One-Day Workshop

This two-day workshop will focus on the assessment, maintenance, and repair of onsite wastewater systems. Prior to the two days of practical training in the field, students will participate in a webinar to review the maintenance requirements in the SPM, along with ASTTBC’s practice guidelines for Maintenance Provider. Following the two days of practical training in the field, students will participate in a webinar to review proper maintenance assessment reports.

Five onsite wastewater systems will be assessed, and recommendations for maintenance and repair provided to the homeowner. These five systems will include both Type 1 and Type 2 gravity, Type 2 pressure and potentially a Type 3 system.

Students will be able to use this training toward needed experience quotas, and/or professional development credits. 

Course Outcomes

  • Review of the maintenance requirements under the Sewerage System Regulation – webinar
  • Review of the maintenance requirements of the Standard Practice Manual – webinar
