Just to scale the challenge for you, in 2012 the installed municipal waste treatment facilities were about $370 billion, and about an $80-billion gap exists to expand those facilities to meet future needs, based on a 2012 estimate. In that regard, the application of science to make sure that whatever form these facilities take is well designed and that they're going to produce the water outcomes we require in the most economically efficient manner does require the application of best practices and science. We've already been able to save municipalities well over $100 million just through collaborating and convening with them to develop standards of treatment that are more effective.
