The manholes circular metal lid usually located in the middle (sometimes to the side) of the street are for access to the sanitary sewer main. Only authorized city personnel can remove the manhole cover and enter the manhole.
Please ensure the manhole covers on your property are clearly visible and easily accessible at all times. Please do not bury them or disguise them. Your assistance in keeping these areas clear will save valuable time when crews are repairing or maintaining the lines.
