The town has been experiencing water shortage and low pressure problems
with their supply system, however, their reasons for these deficiencies
was not clear. Their 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 was
experiencing some difficulty supplying water due to the need to throttle
the valves in the Shell Valley to maintain pressure to the rural users.
The town is also under 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 have been
incorporated into a recommendation 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.
RECOMMENDED LEGISLATIVE ACTION:
The WWDC recommends the project be continued in the New Development
Program at Level II status with an appropriation of $400,000 to provide
for drilling a Madison Formation test well.
The WWDC recommends the project components that were identified for
rehabilitation be included in the rehabilitation program at Level III
status with an appropriation of $335,000. The proposed financing plan
would include a 50% grant and a 50% loan at 4% for 20 years.
