"We are 100 percent pro-rain barrels. We're absolutely for larger rain cisterns in the right place, certainly in cities where there's excess stormwater that drains directly into the Sound," said Mo McBroom, policy director for the Washington Environmental Council.
"But if we run out of water because people are taking it and irrigating a golf course and we can't have a viable farming community, we're in big trouble."
