A letter will be mailed to residents of Richmond and Rubio concerning individual sewer systems and the direction that the county is taking to improve conditions. Supervisor Jack Seward states that residents should receive the letter early next week. He also explained that he met with representatives from the Iowa Department of Natural Resources and they have tentatively approved the county’s direction of action in Richmond and Rubio and asked for a report from the county. Also, at the board of supervisors meeting this week, Seward said that a follow up informational letter will be sent to residents next month.
