(Richmond, IN)--Sewer bills for Richmond residents are going up. The average Richmond customer will see an $11 monthly increase that will be phased in over the next three years after Richmond Common Council gave its approval in a special meeting Monday night. Council voted 6-3 to increase bills to fund court-ordered improvements to the sanitary sewer system. Council President Misty Hollis talked about why the federal government is mandating the improvements. "A lot of people might not know this, but we still have a few places that, when we have a huge rain, our sewer flows into the (Whitewater) river," Hollis said. $33 million in bonds will be issued to fund five projects. $2.5 million in cash that’s on hand at the Sanitary District will be used to pay down the debt.
