must have the following processes (AT A MINIMUM) to be considered for
selection:
1. Membrane pilot unit must include full size pressured ceramic
filtration modules.
a. Pilot skid must include space for a minimum of 1 (one)
module, but alternatives to include multiple modules (2

Recognized as the Jackalope Capital of the world, the City of Douglas,
population 6,400, is a growing Wyoming community located in east
central Wyoming in Converse County along the Interstate 25 corridor
approximately 50 miles East of Casper, WY. Our legacy is rooted in the
RFP: Douglas WTP Pre-Treatment Piloting Unit Page 3 of 9

Oregon Trail pioneers, railroads, and the wild western frontier. That
pioneering spirit essential to survival in the old west still exists today.
Douglas has been called one of the best 100 Small Towns in America and
was recently selected as the best small town in the western United States
to practice medicine. Douglas has a diverse economy and high quality of
life grounded in traditional family values.
With breathtaking views, Douglas sits at 5,000 feet at the foot of the
beautiful Laramie Mountain range, and beside the North Platt River and
is only a short distance from the Medicine Bow National Forest and
Glendo Reservoir. This beautiful location offers many outdoor
recreational opportunities such as hunting, fishing, boating, and hiking.
In addition to being the official home of the Jackalope and a Tree City
USA, Douglas is also the home of the Wyoming State Fairgrounds and
Pioneer Museum, Wyoming Law Enforcement Academy, Douglas
Railroad Interpretive Center, Douglas Community Golf Course and the
Douglas Motorsports Park.
Douglas has a strong economic base primarily influenced by the
availability of rail access, nearby coal resources and related mining
operations, as well as exploration and production activities associated
with oil, gas, and uranium reserves in Converse County.
Section Three
Project Background
The City of Douglas retained HDR Engineering, Inc to analyze issues with
the current water treatment process for the City (slow sand filtration).
The HDR team also completed an alternatives analysis of the Douglas
Water Treatment Plant (WTP) that classified influent water quality and
identified production issues associated with the use of slow sand
filtration. Multiple alternative treatment processes were evaluated with
conventional pre-treatment with low pressure membrane filtration
(MF/UF) being selected as the prefered alternative for pilot testing. Due
to the requirements set forth by the EPA and WYDEQ, piloting of a
treatment unit is required for certification prior to any functional
upgrade. See Exhibit A for Site Layout and Exhibit B for preliminary PFD.
