 61. PROJECT:Lander Water Supply Rehabilitation
SPONSOR:City of Lander
LOCATION:Fremont County
Purpose Chapter Session Account Appropriation Due Date
Level I 8 1995 I $100,000 1996
Level II 46 1997 I $175,000 1998
Level II 81 1999 I $100,000 2000
Level III 16 1999 II $400,000 2003
Level III 96 2000 II $1,696,000 2004

The city of Lander Level III initial application submission was a request for $1,180,000 to replace the existing 20-inch asbestos cement treated water transmission pipeline from the water treatment plant to the Ellis tank, a distance of approximately 12,295 feet. Reconstruction of the Sinks Canyon Highway by the Wyoming Department of Transportation (WYDOT) in 2002 and 2003 in conjunction with the required increase in the treatment capacity of the water treatment plant dictates that the transmission pipeline be replaced.

Water Development Account II funding was approved for the city of Lander water system during the 1999 and 2000 Legislative Sessions. In 2000, $1,696,000 (50% grant and 50% loan) was authorized for the replacement of the raw water transmission pipeline from the intake to the water treatment plant. The raw water transmission pipeline, which is 9,320 feet long, will also be affected by the WYDOT Sinks Canyon Road reconstruction.

The most recent engineering estimate (by Aspen Engineering 10/10/00) for replacement of both pipelines has a total cost of $2,665,500, which can be broken down as $1,240,500 for the raw water pipeline and $1,425,000 for the treated water pipeline. This means the Water Development Account funds authorized for the raw water pipeline are $455,500 above the current estimate. Should the authorizing legislation be changed to allow funding of the raw and treated water pipelines the WWDC funds would be short $969,500 to allow for the replacement of both pipelines. Due to very tight right-of-way constrictions on the upper end of the raw water transmission line (Highway Sta 81+00 to 96+00), it appears that the only place to locate the pipeline is directly under the roadway. It is therefore very desirable that the replacement of the pipeline in this section be accomplished by the highway reconstruction contractor working for WYDOT. The estimated cost for this portion of the pipeline is $760,400. It is recommended that WYDOT be approached to have the pipeline project incorporated into the roadway reconstruction contract.

Total project costs (replacement of raw and treated water transmission pipelines) are thus approximately $400,000 short of funds; assuming $569,500 is contributed by either WYDOT or the city and the existing Water Development Account funds of $1,696,000 is used for constructing the raw and treated water pipelines.

The WWDC recommends that the previous legislation for the raw water transmission pipeline be amended to allow funding for the raw and treated water pipelines; and that additional funding for the project be incorporated in the Rehabilitation Program at Level III with an appropriation of $400,000.
