This section has no associated Explanatory Memorandum

13.  In Schedule 3, in Part 3, after paragraph 3 insert—

“Open-loop ground source heating and cooling systems

4.—(1) For the purpose of paragraph 5(a)(i) of Schedule 2, the description is the discharge of water to groundwater from a heating or cooling system to which sub-paragraph (3) applies with altered temperature.

(2) For the purpose of paragraph 5(a)(ii) of that Schedule, the conditions in relation to a groundwater activity of that description are—

(a)that nothing should be added to water discharged from the system;

(b)that the temperature of water discharged from the system—

(i)subject to sub-paragraph (ii), must not exceed 25o C, and

(ii)must not vary by more than 10o C compared to that in the aquifer from which it was abstracted;

(c)that the system must not be on a known contaminated site or have had a previous contaminative use;

(d)that water from the system must not be discharged less than 50 metres from a watercourse or groundwater-fed wetland;

(e)that water from the system must not be discharged within—

(i)50 metres of a point at which water is abstracted from underground strata, or

(ii)a zone defined by a 50-day travel time for groundwater to reach a groundwater abstraction point that is used to supply water for domestic or food production purposes;

(f)that the discharge of water from the system must be to the same aquifer as that from which it was abstracted;

(g)that water within the system must not be used for any other purpose.

(3) This sub-paragraph applies to a system—

(a)that involves—

(i)the abstraction of groundwater to obtain heating or (as the case may be) cooling, and

(ii)the subsequent discharge of that water; and

(b)that is—

(i)a cooled aquifer system with a volume of less than 1500 cubic metres per day;

(ii)a balanced system with a volume of less than 430 cubic metres per day; or

(iii)a heated aquifer system with a volume of less than 215 cubic metres per day.

(4) In this paragraph—

“balanced system” means a system used for both heating and cooling and where in a 5-year period the ratio of the discharge water temperature to the abstracted water temperature is within the range 0.8 to 1.2;

“cooled aquifer system” means a system used for both heating and cooling and where in a 5-year period the ratio of the discharge water temperature to the abstracted water temperature is less than 0.8;

“groundwater-fed wetland” means a terrestrial ecosystem directly depending on a body of groundwater (within the meaning of the Water Framework Directive) and includes—

(a)

a European site (which has the meaning given in regulation 8 of the Conservation of Habitats and Species Regulations 2010(1));

(b)

a site of special scientific interest (which has the meaning given in section 52(1) of the Wildlife and Countryside Act 1981(2));

“heated aquifer system” means a system used for both heating and cooling and where in a 5-year period the ratio of the discharge water temperature to the abstracted water temperature exceeds 1.2.”.
