| LEVEL: | New Application |
| SPONSOR: | Riverton Valley Irrigation District |
| LOCATION: | Fremont County |
| PROGRAM: | Rehabilitation |
PROJECT INFORMATION:
Flow measurements on the Riverton Valley Canal were conducted as part of the Wind River Basin
study. The Riverton Valley open laterals experience high exfiltration as well as high maintenance
costs. In 1994, the Commission recommended the project be advanced in the Rehabilitation
Program to Level III status with an appropriation of $350,000. This project addressed twelve
laterals under the main canal system. These open canals were replaced by buried pipelines, which
greatly reduced maintenance costs and water losses. The district prioritized system repairs and
work was completed in four phases from 1995 through the spring of 1999. The project
appropriation served as a grant for project materials, with payments only being made for materials
invoiced to the district. The district was responsible for all costs related to project design, permit
procurement, land procurement, construction engineering and construction of the project.
The Riverton Valley Irrigation District would like to rehabilitate the remainder of their laterals in a
similar manner. The district has realized a 25% increase in efficiency since making these improvements.
Continued rehabilitation of the system would further increase efficiencies, assist in
maintenance, and ultimately improve the ability to deliver water to the users. Due to the time frame
since the Level III project was initiated, a detailed cost analysis of piping the remainder of the
laterals is warranted.
RECOMMENDED LEGISLATIVE ACTION:
The WWDC recommends that the project be included in the Rehabilitation Program at a Level II
status with an appropriation of $40,000.
