The improvement scenarios are: scenario 1,use of engineered wetland instead of the current treatment system, scenario 2, use of the engineered wetland as a secondary treatment after the existing treatment system and scenario 3,replace the existing treatment system with a secondary WWTP. The scope of this study is to environmentally assess the existing primary WWTP, in addition to assess the possibility of using the engineered wetland for improving the primary WWTP. To evaluate the performance of each treatment system, Life Cycle Assessment (LCA) approach was applied. Based on the results, the main improvement achieved in all the scenarios is in the category of eutrophication and acidification, as the three scenarios have higher removal efficiency for the nutrients than the current system. Unlike the total reduction in the environmental impact, scenario 3 gave the highest reduction in the category of eutrophication and acidification (25%) followed by scenario 2 (24%) and the lowest reduction achieved by scenario 1 (13%). The analysis revealed that the use of combined system from natural and traditional systems (scenario 2) is the best scenario. However, scenario3 achieved a very close result.</p></abstract><publication_date><month>04</month><day>30</day><year>2013</year></publication_date><pages><first_page>450</first_page><last_page>459</last_page></pages><publisher_item><identifier id_type="pii">831</identifier></publisher_item><doi_data><doi>10.30955/gnj.000831</doi><timestamp>1713267996</timestamp><resource>https://journal.gnest.org/publication/831</resource></doi_data></journal_article></journal></body></doi_batch> </div>
