DOWNTOWN SAN DIEGO (KGTV) -- Has the craft beer craze that overtook San Diego been replaced by a new environmentally-conscious wastewater war of the brews?

Ballast Point will unveiled a new Pilsner Monday from 3 p.m. to 5 p.m. at the Westin San Diego. A Pilsner that features none other than "water from the toilet."

Wastewater, yes. But purified.

Last Friday, San Diego mayor Kevin Faulconer entertained a crowd of onlookers as he swigged a mouthful of Stone Brewing's latest pale ale, appropriately called "Full Circle Pale Ale."

With today's tasting of the "Padre Dam Pilsner," we've reached another level of reuse.

The pilsner is made from the recycled and purified water from the Padre Dam Municipal Water District's Advanced Water Purification Demonstration Facility, which is being recognized as the "Recycled Water Agency of the Year" by the WateReuse California Board.

"Using state-of-the-art technology to purify East County's recycled water, the East County Advanced Water Purification Program will create a new, local, reliable and sustainable drinking water supply." said Allen Carlisle, CEO of the water district. "The end product is water so clean that it is near-distilled in quality."

It seems that local craft brewers are taking notice and supporting this local effort.
