Abstract: This research paper aims at presenting the effect of using tertiary treated wastewater from Nablus Wastewater treatment plant (NWWTP) on some properties of concrete. The research idea have both environmental and economic aspects. The use of tertiary treated wastewater in partial replacement of potable water in concrete mixtures, will save substantial amount of potable water for domestic use. The research variables are water cement ratios (w/c) = 0.5, 0.6 and 0.7, replacement ratios (30%, 60%. and 100%); and curing ages at 7, 14 and 28 days. Different concrete properties were investigated such as compressive strength, natural absorption and workability (Slump). The tests results of concrete cube samples were compared for both types of water, at different replacement ratios and curing ages. The general trend of test results revealed increase in maximum compressive stress of concrete made with w/c=0.5, 0.6, and decrease at w/c=0.7. The recommended replacement ratio of tertiary treated wastewater in concrete mixtures would be 30% to 40%.
