The city council finds that the discharge of water from roof, surface, groundwater sump pump, footing tile or swimming pool or other natural precipitation into the city sanitary sewage system will, and has on numerous occasions in the past, flood and overload the sanitary sewage system to such an extent as to cause significant and grave damage to the waste treatment plant and sanitary sewer trunk system. Such damage is caused by the backup of sewage into the plant, private properties, and pressure damage to trunk lines. The city council, therefore, finds it essential to the minimization of damage to property and to meet Minnesota pollution control agency and city code requirements that the provisions of this chapter be strictly enforced to avoid emergencies in the future.
