Private sewage works (PSWs) is a term used to describe a septic system installed on a single property designed to collect all of the sewage and wastewater generated on that property. PSWs are typically installed where a property cannot be connected to a municipal sewage collection system. PSWs are an effective and economical long-term solution for sewage disposal when installed and operated properly.
A permit is required for the installation of PSWs. Detailed information on PSWs can be found in the Saskatchewan Onsite Wastewater Disposal Guide that can be accessed online, free of charge.
All PSWs in Saskatchewan are subject to the requirements of The Private Sewage Works Regulations and when installed in shoreland development areas The Shoreland Pollution Control Regulations, 1976.
Properties that require PSWs and are located within 152 meters (500 feet) of the high water mark must have a CSA approved sewage holding tank with a minimum capacity of 4,546 liters (1,000 gallons). Sewage holding tanks minimize the risk of sewage contaminating surface water in the event of flooding or seasonal high-water events. Properties in a shoreland development area that are further back than 152 meters (500 feet) from the high water mark have other options for PSWs.
New regulations are being proposed that will combine both The Private Sewage Works Regulations and The Shoreland Pollution Control Regulations, 1976 to create a clear regulatory framework for PSWs in Saskatchewan while modernizing requirements, particularly those for shoreland areas.
As with the above regulations, the Saskatchewan Onsite Wastewater Disposal Guide is currently being revised with a new version expected in the summer of 2018. Property owners that are looking to install a new system, or make changes to their existing systems, should review this guide and contact their local Saskatchewan Health Authority public health inspector for more information.
