Once the tubing is placed into the excavation, the area is backfilled, initially with a material that will not puncture the cs. Example of a groundwater open loop circuit using a supply well and a discharge ccsa Source: If used in closed loop systems, lower density polyethylene tubing also has an increased risk of degradation and cracking. Legislation and regulations change from time to time so it is essential that the most current versions be used.
Circumstances where a person could take more than 50, litres of water or cause interference with any private or public interest in the water include: In some cases, a larger excavation is created to place coiled tubing into the ground.
In a vertical Csq system, the tubing is installed into vertical, including directional or angled, holes and backfilled with a bentonite, cement or sand product. If a designer chooses not to follow the prescriptive requirements of the Building Code Regulationthen the designer must propose an alternative design which meets the objectives and functional statements as stated in the Supplementary Standard SA-1 of the Building Code Regulation When proposing an alternate design for an earth energy system, Supplementary Standard SA-1 requires a designer to meet objectives OH1.
Figure 6 shows an excavator creating a trench. The bottom of the sleeve contains perforations to allow the submersible pump to extract groundwater from the formation through the waterline, towards the heat pump. If you have an interest to serve on this Committee, please contact Muktha Tumkur for additional information. This requirement to obtain a sewage works environmental compliance approval also applies to an individual household open loop earth energy system or ATES earth energy system.
Earth energy systems are a heating and cooling system for buildings or structures that use a fluid to exchange heat with the ground or water. The retained professional engineer or professional geoscientist should conduct a geological study of the area before decommissioning commences. Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards.
Subscription pricing is determined by: Capitalized initials used in the text and symbols of this technical bulletin are defined as follows:. You can download and open this file to your own computer but DRM prevents opening this file on another computer, including a networked server. It is also intended that the new standard will be used as a basis for the promotion of international standards.
The vertical loops are connected at the central point and form part of a continuous loop which extends from the ground into the home and back. The two standards do not provide information on the type of grouting mixtures to use nor discuss when sca types of bentonite or cement are to be placed into the hole. To find out what legislative and regulatory requirements may apply, prior to doing work in or on the bed of a water body or near or adjacent to a shoreline or shorelands area, check with the local Ministry 4c48 Natural Resources District Office, or local conservation authority.
The retained professional engineer or professional geoscientist should design the decommissioning of an earth energy system, which may include the drilling out of the tubing and then filling of these holes, based on the information obtained from the study and the minimum standards and requirements found in:.
The three forms are as follows. For example, if a Source Protection Committee has reason to believe that a restriction on an earth energy system is needed to protect source water, then the committee can suggest that a local municipality pass a by-law or planning approval to restrict the location of an earth energy system. Fsa all of these systems, the vertical holes are preferential flow pathways along which fluid and gas may migrate and pose an environmental risk.
The work for the development of this standard will commence late summer and is expected to be completed the spring of After heat transfer fluid tubing is installed in a hole for a closed loop, direct exchange or BTES system, a material is usually placed in the hole to fill the remaining void space.
Because of the environmental concern over methanol, the Ground Source Heat Pumps Regulation bans the use of methanol as a heat transfer fluid in new closed looped earth energy systems and those that were constructed, altered, extended or replaced after June 1, In some surface water closed loop systems, the tubing is installed in a coiled fashion into the water body at a minimum of two metres below the surface.
The outside loop of a closed earth energy system consists of a continuous sealed underground or submerged loop of tubes through which a heat transfer fluid passes and returns to the heat pump unit. Fas amended. This water is circulated through a heat pump before being discharged back into an aquifer or other water body. If a well, hole or trench intersects groundwater and more than 50, litres of water in a day is being removed out of the hole during the construction process, then the person constructing the well, hole or trench must have a valid Permit To Take Water.
This includes most horizontal closed loop ground source heat pump; an open loop ground source heat pump or a submerged surface water closed loop ground source heat pump; the portion of the ground source heat pump heating and cooling system that is found in a building or a structure such as a pool; and a closed loop ground source heat pump that uses methanol as a heat transfer fluid and was installed before January 1, An example of not meeting the purpose of the Act could be the taking interferes with another person’s well.
As the voice of the U. Before installing an earth energy system in a river or stream valley, a watercourse, a wetland, Great Lakes or a lake shoreline or in hazardous lands within conservation authority jurisdiction, you should check with the local conservation authority to determine if a permit is required under section 28 of the Conservation Authorities Act. Does not apply for individual household Applies and Must be Obtained Before Installation for all other cases.
There are three basic types of outside loops for earth energy systems. There are also two types of thermal energy storage systems to exhaust heat to the ground or groundwater for heat storage and extraction.

Mineralized water, gas and oil can migrate along open holes associated with an earth energy system and impair other fresh groundwater zones. A permit to take water is not required for a taking from a domestic open loop ground source unless the taking does not meet the purpose of the Ontario Water Resources Act.
Spacers are used between the U-loop tubing. The cas waterline is up flow gradient from the discharge waterline. The following definitions and clarifications of technical c48 in the text of the technical bulletin are provided in this section, and are for the purpose of and use with this document.
In some circumstances, oil and gas have migrated into the overlying overburden. You may delete a document from your Alert Profile at any time.
CAN/CSA C448 Series-13
As indicated in Section 2. The void space around the green tubing in the hole has been filled to almost the ground surface with a bentonite manufactured swelling clay product. The discussion in this section applies to all vertical fsa, including open loop, closed loop, direct exchange, and angled or inclined holes.
Oil and gas deposits also reside within these rocks. Proceed to Checkout Continue Shopping.
Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material. The groundwater level in the discharge well is located about the middle of the full depth of the supply well and the level is represented by x448 ellipse within the supply well.
