Donnell & Allred, Inc. has been designing the infrastructure for the Big
Horn Basin since 1932. We are still in business more than 70 years later for
one reason - Service.
Some of the earliest projects completed by Bell & Donnell (our original
name) were the Sunshine and Leavitt Reservoirs. We also were responsible for
many of the irrigation facilities in the Big Horn River valley. We designed
29 new irrigation structures for the Upper and Lower Hanover Canals as well
as structures for Bluff Canal.

Birdseye View of Middle School
|
When CTA Architects and Engineers was hired to design a new Middle School in
Worland, they knew they could rely on Donnell & Allred for local expertise
and efficient services. We worked with CTA throughout the design process, from
providing an existing site survey to designing the site plan to inspecting
building construction. The design team was able to design the project to meet
the expectations of the School Board for well under the budgeted amount. For

This project was a redesign of West Broadway Street in Thermopolis for WYDOT.
There were many challenges that we successfully overcame throughout the design
process. The project included approximately 1 mile of street reconstruction,
redesign of a major highway intersection, 750 ft of retaining wall and a new
storm sewer system. For more details click

Boy's School Water Tower
|
Donnell & Allred took over an unfinished design of a water and sewer line
to the Wyoming Boy's School and completed the design in a timely and
cost-effective manner. The Boy's School needed to upgrade their aging sewer and
water system. We designed water and sewer transmission mains for the five mile
stretch between the Boy's School and Worland's municipal systems. We also
designed a 300,000 gallon elevated Hydropillar water tank. For more details
