Gila River Sand & Gravel Builds The Largest Wash Plant in the Southwest U.S.

Case Study

Gila River Sand & Gravel Builds The Largest Wash Plant in the Southwest U.S.

Location Coolidge, AZ

Industry Aggregates: Sand & Gravel

The Challenge

Gila River Sand & Gravel came to Kimball Equipment and Superior Industries looking to build a high-capacity wash plant, but they didn't have the extra people or time to manage every piece of it themselves.

With that, the project came with some real constraints:

Limited footprint (35 acres) to fit the operation
High water demand
Coordination of multiple systems without delays

Trying to piece that together with multiple vendors would have ultimately slowed down production.

Equipment

Spirit® Sand Plant
Guardian® Screen
Radial Stacking Conveyors
Fine Material Washer

The Solution

Instead of managing multiple suppliers, Gila River Sand & Gravel partnered with Kimball Equipment and Superior to handle the plant as a complete system, from design through start-up.

From the beginning, it was a collaborative process. Gila River had a clear vision, and Superior brought multiple 3D layouts and ideas to the table. The final design came from both.

The finished plant includes:

A 340-foot tunnel feed system with four feeders
Split processing for mortar sand and concrete sand
Blade mills, Guardian® Horizontal Screens, and a Spirit® Sand Plant
A 75-foot thickener with a polymer system for water recovery

Everything ties together, so material moves from feed to stockpile without extra handling or unnecessary choke points.

The Results

Once construction started, the project fell into place without stalling. With clear communication between Gila River, Kimball Equipment, and Superior, everything stayed on track and came together seamlessly.

Today, Gila River Sand & Gravel is running:

The largest wash plant in the Southwest U.S.
A system that recovers up to 98% of its water.
A high-production plant.
A setup that runs efficiently without constant adjustment.

The end result is a beautiful wash plant that does exactly what it was built to do. Produce aggregate, conserve water, and run without wasting time, space, or resources.
