 10. PROJECT:Buffalo Valley Water Supply
SPONSOR:Buffalo Valley Estates Homeowners
LOCATION:Teton County
PROGRAM:New Development
Purpose Chapter Session Account Appropriation Due Date
Level II 46 1997 I $90,000 1999

Buffalo Valley Estates was approved in 1976. The developer put in a well, a 6,000 gallon metal storage tank and a 2" galvanized pipeline system. All the lots were sold and the developer left. Presently 19 of the 28 lots have homes on them. The original well could not keep up with the demand and the 2" line started leaking. Therefore, a second well was drilled in 1988, on Forest Service land, and 50% of the 2" galvanized line was replaced with 4" plastic pipe. In 1994, 600 additional feet of 2" line was replaced with 4" line. It is the feeling of the lot owners that a third well needs to be drilled, the original 6,000 gallon storage tank needs to be enlarged and the remainder of the original 2" galvanized pipeline should be replaced. They also seem to have some electrical problems associated with this system.

The WWDC staff prepared a Level I study in 1996 that inventoried the existing system, evaluated water supply needs, and evaluated water supply alternatives for the water users in the Buffalo Valley area. Preliminary plans and cost estimates were developed for the identified alternatives and a preferred alternative was selected. In 1997 a Level II study was performed to drill a test well and test the well performance and prepare conceptual designs and cost estimates. The cost estimates including the Level II test well show the total project cost to be $465,661.

The WWDC recommends the project be advanced to Level III status in the New Development Program, with a 1998 appropriation of $450,000 plus the 1997 cost of the well at $15,661. The financing plan includes a 60% grant for $279,397 and a 40% loan for $186,264 at 7.25% for 30 years.
