2.3.1.03 On-Site Sewage Disposal

On-Site Sewage Disposal

The Regional Health Authority must be referred to for recommendations regarding all subdivisions in which the minimum lot size is less than two hectares. When considering subdivision proposals with on-site sewage disposal, such as septic tanks, the Medical Health Officer requires that percolation and ground water table tests be performed. The Medical Health Officer or his/her designate must be invited to these tests.

A review by the local Environmental Health Officer or Public Health Inspector may still be required for lots exceeding two hectares if the Approving Officer deems it necessary.

The Approving Officer may not require on-site sewage disposal systems to be constructed prior to plan approval. However, a Discharge Permit from the Environmental Management Section of the Ministry of Environment is required if either of the following is true:

  • The anticipated sewage discharge exceeds 25,000 litres per day
  • The intended land use is not “domestic”
