Free Small Systems Training from the Government of Canada
‘This site contains water quality training materials that provides basic information that can help a person learn how to operate and maintain a micro-system (water systems serving up to and including 25 people). The training has been developed by Canadian federal departments as part of a multi-barrier approach to providing safe drinking water in areas of federal jurisdiction, including on federal lands, in federal facilities and/or in First Nations communities. This includes Federal government employees working in Canada, as well as Canadian Coast Guard, Canadian Forces personnel, and Canadian diplomatic mission staff working abroad.
The training is provided in two parts: the main training is in a video or e-Learning format with the second part being an accompanying document that can be printed for more in-depth training.’
