One might argue that two of the more powerful constituencies in the Democratic party are the Environmentalists, and the Unions.  So what happens when the interests of the two collide?  Let's go to Minnesota and find out:

Heathrow Airport, The Rose Bowl and the Taj Mahal.

What do you think all these places have in common?

They, along with many others, have all taken the flush out of urinals.
...
Right now more than 25 countries around the world, including most of the United States, are installing flushless urinals.

And depending on what it's replacing, one waterless urinal can save up to 40,000 gallons of water a year, but the I-TEAM found that you won't see them here in Minnesota.
...
One of the most effective ways to save water is a water free urinal, but Minnesota is the only state that outlaws them.
...
Plumbers have not been supportive of waterless urinals and have fought against them in other states arguing they will impact jobs.
...
However, the I-TEAM investigation finds the state's Plumbing Advisory Council has had proof of the safety of waterless urinals for years -- proof it ignored.

The minutes from a meeting in 2003, it said the Plumbing Advisory Council was asked to establish a test site for waterless urinals. According to the minutes, "There was no second to the motion and the motion was not acted on."

So I guess that means unions win, because Lord knows... without urinals to prop up the languishing plumbing business, many men with their pants falling down would be out of work.
