 46. PROJECT:Greybull Shell Water Supply/Greybull Groundwater
SPONSOR:Town of Greybull
LOCATION:Big Horn County
PROGRAM:New Development
Purpose Chapter Session Account Appropriation Due Date
Level II 8 1995 I $75,000 1996
Level II 15 1996 I $400,000 1998
Level III 38 1998 I $305,000 2001
Level III 16 1999 I $212,000 2001

The town system consists of an infiltration gallery, two flowing wells, two tanks with 1.3 million gallons of storage, and a number of manual and automatic control valves. The town is under an administrative order from EPA for violations of the Surface Water Treatment Rule associated with the diversion through the infiltration gallery on Shell Creek.

In 1995, the Level II study identified several needed improvements to the Shell Creek transmission pipeline. These improvements were incorporated into a Level III rehabilitation project for the town.

The administrative order has placed Greybull in the position of needing to either build a water treatment plant or find a groundwater source that is not under the influence of surface water. A deep Madison formation well was drilled during 1996, however, the yield was inadequate to replace the infiltration gallery. Analysis and testing of the well has indicated that the well was a good candidate for stimulation or fracturing. This stimulation effort was completed during 1997. The yield of the well was increased from about 60 gpm to about 220 gpm.

The plans and specifications for construction of the water storage tank and the transmission pipeline are complete. The project will be constructed during 2000.

No legislative action is required.
