Of the total volume of 169 million m 3 of treated waste water, almost all was discharged into surface water (96%), while about 2% was discharged on the coast and a little over 2% into ground water.
Tudi prečiščena odpadna voda je bila izpuščena v okolje v skoraj enakih deležih: 96 %v površinske vode, približno 2 % na obale, nekaj več kot 2 % pa v podzemne vode.
