This paper presents several case histories which discuss the formation of mild sulfuric acid in the atmosphere over wastewater in reinforced concrete sanitary sewer facilities. The sulfuric acid in turn attacks the concrete and then the reinforcing steel. This paper discusses several repair alternatives. The timely repair of structures is discussed. If the damage is allowed to go too far then repair costs approach replacement costs.
