§ 15-1521. Supply of water to other public water supply systems.

On any application for a new or increased withdrawal of water for a
public water supply system, the department may require or authorize the
applicant to make provisions for the supply and to supply water to any
area of the state which as determined by the department in its decision
on that application properly should be supplied with water from the
source or sources of water supply sought by the applicant. The owner or
operator of any existing or proposed public water supply system within
such area may apply to the department for a permit to take water from
that source of water supply or from any part of the public water supply
system of the applicant supplied in whole or in part from that source.
If the department so requires, or if it grants a permit, it shall be the
duty of the applicant so to supply water, subject to such requirements
as the department may impose. The price to be paid for the amount of
water so to be taken may be agreed upon between the applicant and the
taker of the water, or if they cannot agree, fair and reasonable amounts
and rates shall be, after due hearings thereon, fixed by the public
service commission. Any such agreement or determination of the public
service commission may from time to time be modified by further
agreement between the parties affected thereby or by the further order
of the commission.
