"In 1995, the city of Olympia, Washington, took a fateful step toward achieving one of the goals in its growth management plan: In order to increase its density, the city eagerly embraced a new technology for the treatment and disposal of wastewater.
This spring, only a decade after adopting the new technology, the city temporarily banned it. Density had increased, all right, but the innovative sewage treatment system that fostered development had also created some headaches mostly environmental ones. In imposing its three-month moratorium, the city said it needed time to sort things out. The next chapter of the story is about to be written."
