Requires water purveyors to notify municipalities they service regarding water supply and water quality issues.

The bill title claims it requires water purveyors to notify municipalities about water supply and quality issues, but the provided bill text does not include this requirement. Instead, the bill amends definitions and sections of New Jersey's water allocation law, focusing on water supply adequacy and budget certification. It specifies that the Department of Environmental Protection can order water purveyors (public water system operators) to develop additional water supplies if current supplies are inadequate, and requires budget certification for such orders. The bill text contains no provisions about notifying municipalities regarding water quality or supply issues.
