2 Fresh surface water WWTP Sewerage (ISIC 37) Chemical production (ISIC 20) Enterprise Households Gross emission ISIC 20: Gross emission Households: Net emissions ISIC 20: Net emissions Households: = 90 Removal rate WWTP:1 - 10/(70+30) = 90% Reallocated load ISIC 20:70 * (1 – 0.90) = 7 Reallocated load Househ.:30 * (1 – 0.90) = = 63 Calculation steps CALCULATION EXAMPLE I

3 Gross emission ISIC 20: Gross emission Households: Net emissions ISIC 20: Net emissions Households: = = CALCULATION EXAMPLE I Table A. Gross and net emissions WWTP ISIC 37 ISIC 20 Enterprise Households
