WASHINGTON (AP) — The District of Columbia water and sewer authority is asking Congress to serve tap water instead of bottled water at the presidential inauguration.

The authority’s general manager wrote Thursday to New York Sen. Charles Schumer saying tap water is a penny a gallon while bottled water costs 100 times more and is environmentally harmful. Schumer announced this month that New York-based Saratoga Springs Water will supply water for the inauguration.
