Policy Text:
In addition to their role under the Building Code Act, the municipality is strongly encouraged to require additional measures to ensure that new earth energy systems within Wellhead Protection Areas do not endanger the raw water supply of a municipal drinking water system. The municipality should:
In Wellhead Protection Area ""A, ; prohibit the installation of all types of earth energy systems.
In Wellhead Protection Area ""B, ; require a qualified hydrogeologist to oversee* the design and installation of new earth energy projects (with the exception of horizontal, closed loop systems) to ensure that the construction of the system meets the requirements of the Ontario Building Code and will not result in contamination of groundwater. For a residential system, the hydrogeologist should assess the potential of encountering problems (such as multiple aquifers, cross-connection of aquifers of differing water quality, high yield formations, gas, salty water) and make recommendations to mitigate them including alterations to the design of the system.
Keep records of the location, size and other pertinent details of new earth energy systems within Wellhead Protection Areas.
Action to implement this policy should be initiated within one year from the date the Source Protection Plan takes effect.
* The Canadian Standards Association standard already requires that a commercial / institutional system be designed and inspected by a professional engineer and requires that a hydrogeologist undertake a site survey
