One of the factors involved in pulling energy from shale through hydraulic fracturing is how much water is needed – typically 2 to 4 million gallons per well. Though that’s not as much water as it sounds (electrical generation for the Susquehanna River Basin requires nearly 150 million gallons per day), it’s a public concern. More on water usage at the FracFocus website.

Water also is an industry concern. It isn’t free, and once the well has been stimulated with fracking, there’s waste water that has to be disposed of or recycled. Enter innovation. A number of companies are tackling the issue.

Schlumberger’s HiWAY flow-channel technology claims to use less water, with greater effectiveness:

“HiWAY technology fundamentally changes the way proppant fractures generate conductivity.... more »

Check out this video by WPX Energy that describes the careful way energy companies are using water from Donegal Lake in south central Pennsylvania for hydraulic fracturing.

Regulatory Manager David Freudenrich notes that water levels in the lake are carefully monitored to make sure the lake has plenty of water for fishing and surface recreation. Below certain levels companies aren’t allowed to draw water for fracking. They also can’t draw lake water at the beginning of trout season, Freudenrich says. Take a look:
