WATERLOO — The city has submitted plans to state environmental officials for a pair of $5 million projects to help prevent ongoing sewer overflows.

Waterloo City Council members unanimously approved “intended use plans” Tuesday for an interceptor sewer along San Marnan Drive and for a new Titus lift station and force main near Midland Street and WCF & N Drive.

The documents to be submitted to the Iowa Department of Natural Resources will clear the way for the city to borrow money from a revolving loan fund set up for statewide sewer and water infrastructure projects.
