MONROE, La. (AP) — The city of Monroe's $6.8 million automated water meter project is 90 percent complete, but city officials don't have an exact time frame for project completion.

Through September, Monroe's residences and businesses will continue to be upgraded with the new digital water meters.

The News-Star reports Vanguard has replaced more than 20,000 of the 22,575 water meters.

Approximately half of the industrial meters have been installed.

Monroe utility supervisor Zack Simmons said the installation of industrial meters has taken longer because the city was required to replace or repair old valves in the existing valve boxes.
