Box 14. Case Study: A Solution in Water Sourcing

At its sites in the Fayetteville Shale play in Arkansas, Chesapeake Energy had been purchasing most of its water for drilling and hydraulic fracturing from private sources and trucking it to the well pads. While this process was working for the company, the truck traffic was causing damage to local roads. In 2008, therefore, Chesapeake decided to look into new water supply sources. The company found that by creating what is essentially a holding lake for the overflow from the Little Red River, it could cut down on some of its trucking needs.

Under the system the company developed, water is pumped from the river to the holding lake and transferred into a gravity-fed pipeline that traverses over 40,000 feet, with fourteen hydrants positioned at crossroads where the water can be pumped into trucks. The piping system reduces the air quality impact and safety concerns of trucking, and serves a dual purpose as a source of water for local fire departments. The project was approved to extract a limit of 1,550 acre-feet of water annually. 1

Although water is only diverted from the river during periods of high flow, as mandated by the Arkansas Natural Resources Commission (ANRC), there were local concerns about how this project would affect the Little Red River’s ecosystem. The river is home to a trout population prized by anglers, so Chesapeake turned to the local chapter of Trout Unlimited for input on the project.

As a result of this collaborative effort, various methods were identified to protect the wildlife in the river—for example, the intake pipe is oriented to face upstream and is covered with a metal mesh to prevent harm to the fish. 2 The company has also instituted monitoring of water quality and both game and nongame fish species in the reach of river surrounding the intake. Working with the community, Chesapeake was able to identify and implement measures to protect the river’s wildlife and its recreational and scenic values to the community.
