Abstract: A procedure for arranging water circulations in an integrated paper mill, the paper making process of which having three partly separate process phases concerning the water circulations (I, II, III). In the first phase, the fiber raw material is pretreated, defibered and cleaned for producing mechanical, chemi-mechanical and recycled pulp, in the second phase the pulp is treated further for improving the quality, and in the third phase it is made into paper or board. The circulation waters of the first process phase are concentrated by circulating the filtrates of the concentration and pressing phases counter-current inside the water circulation (I), and the circulation water thus concentrated is conducted into an effluent evaporation plant to be concentrated and then burnt in a combustion boiler. The water quantity discharged from the water circulation (I) of the first process phase is replaced by conducting such circulation waters of the paper mill into the front dilution of the press.
