(KMOV) -- A water main break behind the Macaroni Grill in St. Peters erupted around 10 a.m. in St. Peters on the 100 block of Costco Way, closing the restaurant.
St. Peters city workers fought the geyser for a half-hour before successful stopping the break.
City officials say no one was injured and no damage was done.
Witnesses say Costco was out of water for some time because of the break and Macaroni Grill remains closed.
St. Peters officials say they are waiting for a private company to assess the valve damage before restoring water back to the restaurant.
