The search for predicting the concentration of trihalomethanes in drinking water equations of the surface water intake was carried out. The turbidity, chromaticity, permanganate oxidation of the water source and the dose of chlorine are taken as dependent parameters.The listed parameters are an indirect reflection of the gunim substances presence in the water source. These substances are precursors for the formation of trihalomethanes. In addition, it was found an equation by which it is possible to predict the dose of chlorine depending on the unlisted generalized indicators of water quality. The coefficients of determination of the obtained equations vary between 0.78 - 0.96, and the average relative forecast error is 6.5 - 19.3%.
