Section 29 Disposition versions

2022-03-01

29. A ground-source geothermal system that does not withdraw water must be constructed in accordance with the following conditions:

(1)  the system must not be located in a littoral zone or in a high-velocity flood zone;

(2)  the components situated below the soil’s surface must be made of materials that are new at the time the facility is installed;

(3)  the system cannot use ethylene glycol, potassium acetate and methanol for its operation;

(4)  the work to construct the system must be carried out in such a way that no water is contaminated and no environmental degradation occurs;

(5)  when the system is installed at a depth of over 5 m in the ground, the soil must be graded above the underground components and over a distance of 1 m around the system in a way that prevents water pooling and water runoff towards the components;

(6)  if the system is installed in a low-velocity flood zone must be designed to resist a 100-year flood and the work must be carried out below the soil’s surface;

(7)  the watertightness of the components must be assessed before the system is operated.

29. A ground-source geothermal system that does not withdraw water must be constructed in accordance with the following conditions:

(1)  the system must not be located in a littoral zone or in a floodplain having a flood recurrence interval of 20 years, or in the identified floodplain of a lake or watercourse unless the 20-year and 100-year flood recurrence intervals have been distinguished;

(2)  the components situated below the soil’s surface must be made of materials that are new at the time the facility is installed;

(3)  the system cannot use ethylene glycol, potassium acetate and methanol for its operation;

(4)  the work to construct the system must be carried out in such a way that no water is contaminated and no environmental degradation occurs;

(5)  when the system is installed at a depth of over 5 m in the ground, the soil must be graded above the underground components and over a distance of 1 m around the system in a way that prevents water pooling and water runoff towards the components;

(6)  if the system is installed in a floodplain with a flood recurrence interval of 100 years must be designed to resist a 100-year flood and the work must be carried out below the soil’s surface;

(7)  the watertightness of the components must be assessed before the system is operated.
