Cities Facing Major Wastewater Challenges

"The sewage treatment systems in many cities are outdated. Many were built more than a century ago. They need costly upgrades to meet federal clean-water standards. But the federal money available for such updates is a fraction of what it was a generation ago.The problem is part of the challenge the nation faces in overhauling highways, bridges, mass transit and other public works systems that are straining from decades of wear and tear and the demands of a rapidly increasing population. The question is how such improvements can be made and who will pay for them."
