Green River, Wyoming

Green River was incorporated in 1868..

The first waterworks were built in 1868 by the Union Pacific Railway Company to supply their locomotives.  The Union Pacific incorporated the Green Mountain Water Works Company in Iowa around 1887 and they built a larger system that served the cities of Green River and Rock Springs. .

The water system was sold in 1960 by the Southern Wyoming Utilities Company, a subsidiary of the Union Pacific Rail Road, to the Pacific Power and Light Company (PP&L).

PP&L sold the water system in 1988 to cities of Green River, Rock Springs, and other entities that formed the Joint Powers Water Board.

Water is supplied by the Joint Powers Water Board and distributed by the City of Green River.

Package worked out after nearly 3 years of negotiations between cities, board.
Following nearly three years of negotiations between a joint powers water board and two city governments, the purchase of a water system to serve Rock Springs, Green River and several nearby communities may be completed in February. A $22 million purchase-and-improvement package for the takeover of the $15.5 million Pacific Power and Light Corp. system, one of the few privately-owned water systems in the state, was worked out in April among the two city governments and the Joint Powers Board. The package includes $15.5 million to pay PP&L and another $6.5 million for improvements to the systems. To finance the deal the board will use $11 million appropriated by the Legislature in 1986 and $11 million in locally-issued revenue bonds. Joint Powers chairman Paul Anselmi said that the 90-day purchase contract calls for closing the deal the first week in February. But the sale is subject to final approval by the PPL board and the sale of $11 million in revenue bonds by bond underwriters Kirkchner Moore and Co. A 90-day purchase agreement was signed Nov. 3, and final purchase is scheduled for the first week in February. Public works departments of the two cities are busy working out details for the takeover. The major sticking point during negotiations was whether the Joint Powers Board would handle both treatment and distribution of water, or whether the two municipalities would handle distribution.
