Bottled Water:

In Alberta, the town of Strathmore has grown so quickly that it is running out of room for its sewage.

SO - it decided to put it into the Bow River, UPSTREAM from the very large Sikiska Nation (and a few other towns, no doubt).

The Siksika people raised a great outcry (who wouldn't), but Strathmore town council "fixed" the problem by trucking in bottled water for the nation.
