PROJECT INFORMATION:
The city water supply system consists of two Madison Formation wells
located about 20 miles northeast of Worland and north of the Nowood
River. In December 1996 the pipeline ruptured in the Sand Creek area.
The break was repaired but broke again in the same reach. The system
was repaired with a short term emergency fix. This fix was funded
partially with a Level III construction authorization by the 1997
Legislature.
The 1997 Legislature also authorized a Level II analysis of the pipeline
and the rehabilitation needs. This work was conducted and it revealed
that the pipe material is in extremely good condition, however, the
soils the pipeline is laid through do not have the strength to
adequately support the pipeline if saturated. Areas of the pipeline are
more at risk than others. The study also identified the need for
electronic monitoring of the pipeline and also the need for an automated
shutoff system at the well heads.
RECOMMENDED LEGISLATIVE ACTION:
The WWDC recommends the project be advanced to Level III construction
status with an appropriation of $300,000. The WWDC further recommends
that the project financing include a 50% grant ($150,000) and a 50% loan
($150,000) at 7.25% interest and a term of 20 years.
