TWIN FALLS -- The city of Twin Falls had a dilemma a few years ago.
The Environmental Protection Agency moved to insure the Snake River's cleanliness by increasing restrictions on waste water discharged into the river.
They basically told the city the runoff needed to be cleaned up and it was going to cost $5 million to build a new water treatment facility.
That is when city engineer Mike Trabert pitched a plan that is the first of its kind in the nation: a series of wetlands, ponds, using the natural ecosystem and its complex filtering process to take the irrigation water, clean it up, and return clean water to nature.
