(Richmond, IN)--Richmond Sanitary District rates were discussed when Richmond Common Council met Monday night.  Significant upgrades to the stormwater and sewage systems are needed at the Midwest Industrial Park to allow the industrial park to grow to capacity.  A variety of sources to finance the upgrades are being sought, but that could include a rate increase.  Jerry Purcell, who sits on the city’s finance committee, said that the city sought help from the county, and that request was turned down.  That denial means this..."that means that the full 24% increase in rates would have to come into effect at six percent per year for four years in a row," Purcell said.  Council did not vote on the issue Monday night.  It will address the proposed increase again in a couple of weeks.
