Professional Practice Guidelines: Onsite Sewerage Systems

Video Length: 1:28:57

Date Recorded: July 28, 2020

This webinar will review Engineers and Geoscientists BC's Professional Practice Guidelines - Onsite Sewerage Systems. These guidelines help professionals to better manage and design onsite sewage systems under BC's Sewerage System Regulation.

The webinar presenters will review the guidelines cover-to-cover, with interesting anecdotes and tips about the "good, bad and ugly" of engineering design practices. The presentation will focus on how to meet the intent of the professional practice guidelines when practicing in this area.

Presenters will answer questions about Professional Practice for onsite systems including:

  • Purpose of the Practice Guideline
  • Value of the Guidelines for a practicing professional
  • Requirements of the Sewerage System Regulation (a summary only)
  • The Standard Practice Manual
  • Roles that you might take on a project
  • Your responsibilities when supervising other professionals or technicians including Registered Practitioners.
  • Elements of an "adequate"field review
  • The professional’s role in operation and maintenance
  • Are you qualified to design an onsite system?
  • What is a "professional competent in the area of hydrogeology" in Section 3.1 of the Regulation
  • Important sewage source characteristics
  • Elements of a complete site evaluation
  • Documenting the link between the site conditions and the design
  • Documents to file with the health authority
  • Other documents required to meet the Guidelines
  • Special situations to look out for when planning an onsite system
  • Necessary and useful references (regulations, guidelines, manuals)
  • Useful checklists
  • What to consider when departing from the SPM standards
