Abstract—This research utilized Life Cycle Analysis (LCA) within SimaPro 9 software to evaluate the potential environmental burdens: global warming, eutrophication, acidification, and ozone layer depletion of three Decentralized Wastewater Treatment Systems (DWWTS) in Jordan over the entire period of its life cycle of construction and operation phases. The obtained laboratory test results showed that Feynan (M1) has the best performance regarding treatment efficiency, where the treated effluent parameters TN, TP, COD, and BOD were the lowest compared to Jerash (M2) and SMART (M3). On the other hand, the overall outcomes show that M3 and M2 are approximately 25% and 50%, respectively, compared to M1 contribution in burdens. Construction of wetlands has the highest contribution to most of the environmental burdens of the three plants. It was found that cement production is the key factor causing environmental burdens resulting from the construction of these plants. Whereas concrete blocks, reinforcing steel, and PVC pipes have less contribution. LCA is approved as a supportive investigation of the environmental burdens of such plants that guide decision-makers in developing new strategies to achieve sustainability.
