During the 1996-1997 Level III Rehabilitation Program it was discovered that the severity of the
corrosion 36 inch diameter transmission pipeline was not as extensive as was anticipated, therefore,
this pipeline will not need to be replaced. However, the corrosion of the 24 inch transmission
pipeline was discovered to be worse than what was documented in the 1995 Level II study. This
pipeline will now need to be replaced. This project is currently under design with the start of
construction anticipated in the spring of 1999 and completion for the fall of 2000.
The second component of this project is to rehabilitate the Laramie River Pioneer Canal Diversion
structure to accommodate winter flows. Recent growth and population projects require the city to
operate its water treatment plant on a year round basis. Presently winter flows to the treatment
plant are measured by installing a temporary flume which is plagued by icing conditions. This
project will provide a permanent solution for diverting and measuring the flows which will improve
the winter time operation. This part of the project is complete.
The pipeline replacement started in the summer of 1999 and is scheduled for completion in the
summer of 2000. A second element of the pipeline project will be constructed in the winter of
2000-2001 due to the need for the line to be shut down at that time. Upon completion of this
element, the project will be complete.
