The article presents the results of experimental studies exploring the possibility of applying the dewatered sludge water treatment as a component of concrete mixtures to address the issue of disposal. The study of the properties of concrete samples made with sediment content from 0 to 33 percents allow to state the fact of the deterioration of strength by increasing the volume of the dried sludge. If the sludge volume in the concrete is 11%, the strength is reduced by 33 ÷ 35 percents; the strength of the concrete is reduced by 57 ÷ 61 percents when the content of sludge in the solution of about 20 percents; the strength of the concrete is reduced by 75 ÷ 77 percents when the content of sludge in the solution of about 30 percents.
