Septic System

The Municipality issues permits and inspects all sewage systems with a daily design flow of less than 10,000 litres per day.

When is a Septic Permit Required?

A septic permit is required for new construction; replacement of existing system, tank replacement and when lines are added or lengthened.

It is a requirement that on-site sewage systems be designed and installed by licensed professionals qualified by the Ministry of Municipal Housing & Affairs. You may however, install and repair your own septic system, although you will still require a permit and inspections from the Building Department. 

For further information, or to obtain a copy of the Septic Permit Application Worksheet, please contact Water Wastewater Services.
