A method has been developed to determine the growth of bacteria in drinking water in laboratory scale by measuring the increase of biomass in the vials. Parameters used are turbidity at 12°, forward scattering and total cell numbers, counted under the microscope. The method is described in more detail elsewhere. In addition to the growth rate the yield coefficient is a decisive parameter to give evidence on the efficiency of the water treatment process. The results can be used to decide whether or not disinfection of the drinking water is necessary. Investigations in different water plants treating surface waters are presented and it could be shown that this microbiological method reacts more sensitive than any chemical parameter. An influence of the seasons and of algae on the water quality could be found.
