(Richmond, IN)--Richmond residents are facing the possibility of a significant increase in their water bills.  Indiana American Water has filed a request through the Indiana Utility Regulatory Commission for an increase that could amount to more than $14 per month for the average residential customer.  Indiana American said that the increase is necessary to cover $875 million in planned infrastructure upgrades.  The increase would come in three phases, beginning with a 12% increase in January of next year.  Public hearings are a requirement of the process of implementing an increase.
