Natural water system in Iraq is facing massive destruction and quality degradation mainly due to absence of an effective protection regulations against direct discharge of pollutants, and inefficient wastewater treatment at Iraq’s sewage treatment plants. Alsamawah City is the center of Almuthanna Province in Southern Iraq. The wastewater treatment plant that serves the city is facing major problems related to improper design and/or implementation of structural plan, lack of professional operators, power shortage, and lack of maintenance. An environmental evaluation of the plant was conducted. The plant was not able to reduce the tested contaminants properly, and failed to comply with standards. Effluent average concentration of oil and grease, TSS, CL-, NH3, COD, and H2S was 42.0, 5.4, 3.5, 1.6, 1.2, and 1.2 times higher than the local standards, respectively. It complies only at the events when a contaminant is originally had low concentration in the raw sewage. In most sampling events the results show that wastewater was leaving plant with little to no treatment, turning the plant into the top point source polluter in the province. To quantify and show decision makers the damages occurred due to improper treatment at the plant, life cycle assessment methodology (endpoint approach) was used. Annual damages from Alsamawah WWTP are 7.3 (±0.8) years loss in human life, 2.5×10-2 (±2.9×10-3) species loss in the area, and $1.1×10+7 (±1.2×10+6) more expenses needed for future generations for resources.
