In accordance with the requirements of the Safe Drinking Water Act and Ontario Regulation 170/03, it is the responsibility of the operating authority of the drinking water system to prepare an annual report. The City, as the operating authority, prepares the annual reports. Copies of all reports are available to the public and may be picked up at the Orillia City Centre, 50 Andrew St. S., Suite 300. You can also download an annual report from the listed documents below.
Any inquiries regarding water test results should be directed to the Water Filtration Plant, 705-325-6800.
Lead Water Services
Before 1953, lead was commonly used in pipes. Houses built after 1952 typically used copper and, more recently, plastic for water service pipes. The Ontario Drinking Water Standard for lead is 10 micrograms per litre. This means that water with a lead concentration below this standard does not represent a health hazard. The water flowing through Orillia's distribution system has a very low level of lead - less than two micrograms per litre, on average. Houses that do not have lead service piping receive water that contains this low level of lead. However, if water travels through a lead pipe between the water main and the house, it can pick up trace amounts of lead from the interior surface of that pipe, increasing the levels of lead.
Municipal residential drinking water systems are required to have a specified number of home and business owners in higher-risk areas volunteer to have their tap water tested for excess levels of lead twice a year - in winter and in summer. Drinking water system owners collect samples from indoor taps and from the distribution pipes that deliver drinking water to properties, to be analyzed.
Large municipal residential systems that report lead results above a certain level (threshold) over several sampling rounds must prepare and submit a corrosion control plan, showing how they will reduce the concentration of lead in their drinking water.
System owners and operators must provide the people who live in these homes or work in these businesses with a report of the test results. If these tests show that a drinking water sample from plumbing exceeds the standard for lead, municipal and non-municipal owners and operators must report the results to the local Medical Officer of Health and work with the local health unit to tell the people who live or work in these buildings what they can do to reduce their exposure to lead in drinking water.
The City has completed the sampling requirements and is currently doing reduced sampling on an annual basis due to the low threshold limit results received from the testing provided.
