[103I.631] INSTALLATION OF A SUBMERGED CLOSED-LOOP HEAT
EXCHANGER.
new text end
new text begin Subdivision 1. new text end
new text begin Installation. new text end
new text begin
Notwithstanding any other provision of law, the
commissioner must allow the installation of a submerged closed-loop heat exchanger in a
water supply well. A project may consist of more than one water supply well on a particular
site.

new text begin Subd. 2. new text end
new text begin Setbacks. new text end
new text begin
Water supply wells used only for the nonpotable purpose of providing
heating and cooling using a submerged closed-loop heat exchanger are exempt from isolation
distance requirements greater than ten feet.
new text end
new text begin Subd. 3. new text end
new text begin Construction. new text end
new text begin
The screened interval of a water supply well constructed to
contain a submerged closed-loop heat exchanger completed within a single aquifer may be
designed and constructed using any combination of screen, casing, leader, riser, sump, or
other piping combinations if the screen configuration does not interconnect aquifers.
