The Town of Sinclair is an incorporated municipality with a population of 500. The town and the Sinclair Refinery share a common water system. The water treatment and distribution system for the Town of Sinclair is operated by the Sinclair Refinery. The town has identified several deficiencies in their supply and distribution system. The existing 75,000 gallon tank was constructed in 1924 and is badly corroded. In 1993, the town requested funding for a water supply master plan to assess present/future needs and to evaluate the entire water system that was constructed seven decades ago.

The Level I master plan was completed by the WWDC in 1996. This study indicated that the treatment plant, tank and transmission and distribution lines need to be upgraded. The town and refinery have an agreement for the operation and maintenance of the water system. The town owns the water right. For the use of 90% of the water, the refinery pays up to $15,000 for operation and maintenance of the water system per year. The water system consists of a pretreatment unit which is located at the river. The water is run through a final treatment plant that purifies the water. Most of the refinery's 90% does not need to be potable. Therefore, they are not interested in the final treatment of the water. In addition to technical issues, the study will focus on resolving the fair share project cost for the refinery and the sponsor. The project was delayed and placed on a Level II - Hold status pending resolution of institutional issues between the Town of Sinclair, the Sinclair Refinery, and the City of Rawlins that has never been fully resolved.

The town of Sinclair requested a 1999 Level II water supply master plan study to provide additional information to the Level I study done in 1996 for their use in prioritizing their system's rehabilitation.

No legislative action required.
