c)the municipal sewage treatment plant must be protected from these substances or other properties that may disturb the processes in the plant or be harmful to the personnel;

d)the quality of the sludge in the sewage treatment plant must not be deteriorated in a way that makes the sludge inappropriate for agricultural use or other purposes in an environmentally sound way; 

e)the sewerage system must not be deteriorated due to the content of substances in the effluent water from industries and other point sources;

 f)limit values for these substances based on the best available technology should be established separately for industry and other relevant sectors discharging indirectly;

 g)industrial connections and other point sources connections must be authorized before the connection is made and supervised by authorities thereafter,
