Wyoming Statutes Title 16. City, County, State and Local Powers § 16-1-108. Obligations and responsibilities of participating agencies

(a) No participating agency nor any legal entity created pursuant to this act shall construct, operate or maintain any facility or improvement other than for service to and use by the participating agencies and their resident customers, except for undertakings pursuant to W.S. 16-1-104(c)(xii).

(b) No agreement pursuant to this act shall relieve any participating agency of any obligation or responsibility imposed upon it by law except to the extent of actual and timely performance thereof by a joint powers board or other legal or administrative entity created by an agreement hereunder, the performance may be offered in satisfaction of the obligation or responsibility.

(c) After April 1, 1998, any legal entity created pursuant to this act or any of its participating agencies, which owns, constructs, operates or maintains a municipal or rural domestic water supply system funded in whole or in part by state grants or loans, shall not assess public entities or individual water users in the cooperating agencies' service area water rate charges which exceed the actual costs of providing and delivering water to the point of connection to the public entities' or individual water users' water system. The governing body of the entity may establish one (1) or more service areas in each of which an average water rate may be used for all customers. A one time connection fee or system investment fee reasonably calculated to permit recovery of a proportionate share of the system infrastructure cost necessary to treat and convey the water may also be charged. A one-time fee may also be charged to recover reasonable expenses incurred by the public entity in determining the actual costs of treating and delivering water to the point of connection. Charges for special services such as customer's line maintenance shall be in addition to the water rate. As used in this subsection, “actual costs of providing and delivering water” shall include a proportionate share of the following costs related to the water system:

(d) If requested by the party seeking water service who resides outside the public entity's service area and upon approval of the public entity, subsection (c) of this section shall not apply if the ratio of the established rate charged to customers outside the area to the rate within the public entities service area is less than one and one-quarter (1.25) to one (1).
