1. Charges in respect of industrial effluent

The charges referred to in Section 7 of the by-law, are calculated as set out hereunder:
(1)The charge is, subject to the succeeding provisions of this Schedule, the amount obtained by applying the formula calculated in terms of item (2) below.
(2)Vw (SVC) + VieT (COD-1000)/1500 + VieT (SF)Where"Vw" is the total volume, expressed in kilolitres, of wastewater discharged from the premises during the period concerned."SVC" is the sewerage volumetric charge in terms of the sanitation tariff."Vie" is the total volume, expressed in kilolitres, of industrial effluent discharged from the premises during the period concerned."T" is the cost, as determined by the council, of treating 1 kilolitre of wastewater."COD" is the chemical oxygen demand of the effluent in milligrams per litre. In the event of the COD being less than 1 000, the COD factor falls away."SF" is the surcharge factor of the effluent calculated according to the formula: SF = (X-L)/Lwhere"X" is the concentration of one or more of the parameters listed in Schedule 2."L" is the limit applicable to that particular parameter.(i)No factor calculated by this formula may have a value less than zero;(ii)In the case of the pH parameter X represents the pH value and, if (X-L) results in a negative value, a positive value of the same magnitude must be substituted.
(3)The COD of industrial effluent is the rolling arithmetic average of four samples taken at any time during a six to twelve month period.
(4)The SF of industrial effluent is the latest value determined.
(5)The SF is cumulative for all parameters which are outside the limits set in Schedule 2.
(6)If, for any reason, the requisite number of samples referred to in the items (3) or (4) above are not taken, or more than four samples are taken, council may determine an equitable COD and/or SF.
(7)The owner/occupier of any premises is entitled to receive, on request, part of any sample taken from the premises before that sample is removed by council.
