3 Industrial Effluent Pollution Effect Pollution Impact on Environment
Conveyance Infrastructure not Coping Fat from abattoir and TSS from rumen content, as well as other suspended solids from more industries on the same line damaging/blocking sewer outfall 3

4 Industrial Effluent Pollution Effect Pollution Impact on Environment
Conveyance Infrastructure not Coping Blocked line overflowing with abattoir effluent (COD > 8 000mg/l) Suspended Solids also damaged the pump station in this case 4

5 Industrial Effluent Pollution Effect COST Impact on Treatment
Assume Plant Copes with Load (Not Overloaded) COST Ti – Monthly charges associated with industry’s effluent C - The C value is a factor in percentage for the full cost of effluent treatment and therefore includes amongst other components, treatment, distribution, admin and resources charges, etc. The percentage adopted is typically 15% of the sanitation budget. Qi - sewage flow (as defined in the Council’s Waste Water by-laws) originating from the relevant premises in kilolitres per day determined for the relevant month Qt -five year average of total sewage inflow (as defined in the Council’s Waste Water By-laws) to the Council’s sewage disposal system in kilolitre per day 5

6 Industrial Effluent Pollution Effect COST Impact on Treatment
Assume Plant Copes with Load (Not Overloaded) COST CODi - average chemical oxygen demand of the sample originating from the relevant premises in milligrams per litre determined for the relevant month CODt - five year annual average chemical oxygen demand of the sewage in the total inflow to the Council’s sewage disposal system in milligrams per litre; Pi - average Ortho-phosphate concentration originating from the relevant premises in milligrams phosphorus per litre determined for the relevant month; Pt - five year annual average Ortho-phosphate concentration of the sewage in the total inflow to the Council’s sewage disposal system in milligrams phosphorus per litre; 6

7 Industrial Effluent Pollution Effect COST Impact on Treatment
Assume Plant Copes with Load (Not Overloaded) COST Ni - average ammonia concentration originating from the relevant premises in milligrams nitrogen per litre determined for the relevant month; Nt - five year annual average ammonia concentration of the sewage in the total inflow to the Council’s sewage disposal system in milligrams nitrogen per litre; SSi- average suspended solids concentration originating from the relevant premises in milligrams per litre determined for the relevant month; SSt - five year annual average suspended solids concentration of the sewage in the total inflow to the Council’s sewage disposal system in milligrams per litre; a, b, d, e and f are portion associated with treatment and conveyance, removal of oxygen demand, removal of phosphates, removal of ammonia and removal of suspended solids respectively. 7
