OMAHA, Neb. (AP) — Omaha utility officials say increased water usage is putting a strain on the system, and voluntary restrictions could be down the road as the worst drought in 25 years continues.

Mark Doyle of the Metropolitan Utilities District says the city is using about 184 million gallons of water a day. He says the water supply is not in danger, but voluntary water restrictions would ease the stress on the system.

He says there are no plans currently for voluntary restrictions, but his team is analyzing the situation daily.
