/ The Bloomington-Normal Water Reclamation District began treating effluent from the Twin Cities in the early 1900s, but new restrictive standards for phosphorus emissions will require substantial investment to meet a 2035 deadline. The mayor of Normal hopes the massive federal infrastructure bill will include money for water treatment plant upgrades in Bloomington-Normal. Chris Koos says if members of the community have to pay the $160 million bill, user rates and tap-on fees will rise significantly — and that could hinder economic development. "Say it's a manufacturing business like Rivian; if they build a new facility, there's a tap-on fee and it can be pretty expensive. To make it more expensive is not a path we should go down unless we absolutely have to," said Koos.
