The National Association of Clean Water Agencies says it’s worried about how big cities and utility companies will fund lead pipe replacement and other big projects in the future. Right now, the association says, the federal government provides low-interest loans for those types of projects, but, with a lot of cost cutting happening, those programs could be in danger. If they go away, cities and utility companies will have to borrow money at a higher interest rate, which will lead to higher rates for customers.
