Marathon Oil Company Water Treatment Facility Wins 2012 AAEE Award

Innovative Adam’s Ranch facility surpasses water discharge limits, controls costs, protects environment

April 30, 2012

SHERIDAN, Wyoming—CDM Smith's first-of-its-kind water treatment and reuse system for the Marathon Oil Corporation Adam’s Ranch water treatment facility in Sheridan, Wyoming has received the Excellence in Environmental Engineering Honor Award in Industrial Waste Practice from the American Academy of Environmental Engineers (AAEE). The cutting-edge, environmentally friendly facility uses a patent-pending treatment process that reliably, safely and cost-effectively surpasses all water discharge limits, preserves natural resources and fresh water supplies, and controls treatment costs.

 
The system allows effluent to be reused for irrigation and supports holistic water management in the Powder River Basin—eliminating deep-well injection or direct discharge and extending water resources for local farmers. 

CDM Smith designed, constructed and is now operating the integrated green sand filtration, ion exchange and reverse osmosis process that operates at a very high water recovery rate—more than 99 percent—and dramatically reduces the use of chemicals, such as sulfuric acid. Consistently delivering compliant water, the system allows effluent to be reused for irrigation and supports holistic water management in the Powder River Basin—eliminating deep-well injection or direct discharge and extending water resources for local farmers.

Because the new process requires little chemical addition and produces a small amount of brine, which can be managed onsite, the number of trucks to the rural Wyoming site is cut by 75 percent. This greatly reduces operational costs, traffic volume, and the potential for accidents and hazardous material spills—major benefits for the client, landowner and farming community.

To get the plant online in less than 1 year, CDM Smith used a design-build approach to address complex piping layouts, minimize potential design conflicts and maintain the tight project schedule. The new system also reuses the existing building and much of the existing equipment to significantly reduce the plant’s final cost. Design flexibility allows for future upgrades or the cost-effective relocation or reuse of equipment.

To cap the successful effort, the entire project—totaling 17,000 hours—was completed without a single safety incident, an accomplishment recognized by the National Safety Council with a valued Safety Performance Award. The innovative water treatment solution enables Marathon to continue operating their gas field, keeping facility employees working and contributing to the local economy.

CDM Smith provides lasting and integrated solutions in water, environment, transportation, energy and facilities to public and private clients worldwide.
