7.    The advanced secondary quality wastewater treatment system, which is an example of the
      approved systems, may only be used on premises that generate per day:

         a) a maximum hydraulic loading of 90 L per 3 m length of AES piping system.
         b) a maximum organic loading of 240 mg/L BOD5.
         c) a maximum total suspended solids of 300 mg/L.

8.    The system must continue to meet the requirements of an advanced secondary quality
      wastewater treatment system, producing the following effluent quality —

         a) 90% of the samples taken must have a BOD5 less than or equal to 10 g/m³ with no sample
            greater than 20 g/m³.
         b) 90% of the samples taken must have total suspended solids less than or equal to 10 g/m³
            with no sample greater than 20 g/m³.
9.    Each system must be serviced in accordance with the details supplied in the owner’s operation
      and maintenance manual.
