Fort Madison, IA – Sewer rates could be on the rise in Fort Madison. The city council approved the first reading of an ordinance that would increase sewer rates by about 15 percent. The measure, which would take effect July 1, must still be voted on two more times. City Manager Bill Kelly says the revenue will be used to upgrade the city's westerly pump station. Kelly says that will bring the facility up to code. Keokuk Contractors won the contract with a bid of about $1.3 million. Construction is expected to begin this summer.
