A plumbing permit is required for the installation or replacement of a septic tank that connects to a municipal low-pressure main (municipal STEP sewer system). 

All septic and holding tanks are required to comply with the size requirements as outlined in the Alberta Private Sewage Systems Standards of Practice (ABSOP) 2015 edition, section 4.2.

Note: A separate plumbing permit may be required for water/sewer connections.  

Private sewage disposal

On many rural properties and some industrial sites, private on-site sewage disposal systems are used to collect, treat or partially treat and/or dispose of wastewater. It is important to have a properly designed system based on the land use needs and site conditions in order to ensure efficiency and functionality.  

Private sewage system requirements should be assessed alongside any on-site development including, but not limited to, the construction of a new building, the expansion or alteration of a building, the changing or intensification of the use of the site (i.e. growing a family, adding a home-based business, etc.) or any other change to the site that could impact water usage and wastewater disposal.  

Applying for permits in-person

Please submit the following:

• A completed Septic Tank Plumbing Permit application (Connection to municipal low-pressure main)

  • proposed location of the system components

  • locations and dimensions of wet lands, water courses, ponds, streams and dugouts 
  • existing buildings and structures on the property

What you need to know

There are numerous variables that need to be considered in the design of a Septic Tank Plumbing permit including, but not limited to, size of property, building size and use.

The Safety Codes Council has produced a number of documents that provide information and recommendations regarding various types of projects including private sewage system development. These are available here.

Strathcona County Safety Codes Officers are available for technical inquiries and can be reached at 780-464-8080. They can provide information regarding tank sizing and separation distances and assist with obtaining additional relevant information to support the preparation of a system design. However, Safety Codes Officers do not design PSD systems.  

Once installed, private sewage systems require regular and ongoing maintenance. Be sure to follow all operations and maintenance processes for your system.
