Wastewater is considered one of the biggest environmental problems faced by the prohibitive development of cities in various countries of the world due to the health and economic risks that this entails. To confront these dangers, a great technological development occurred in the field of sewage treatment and treatment techniques and methods have developed based on environmental controls that are related to the nature of Water and the final goal of its treatment, and achieves economic considerations and follow-up environmental impacts with the need to choose the most appropriate methods of management and sustainability. This study sheds light on the use of sustainable technology for wastewater treatment in the southern Libyan cities. In order to highlight the environmental and economic benefits resulting from the application of this technology derived from nature in Libya, where the study relied on the descriptive analytical approach to design a treatment plant that operates with the technology of stabilization ponds consisting of 1 facultative pond followed by 2 maturation ponds with an estimated area of 4 hectares and meet the standard output BOD5 of no more than 25 mg/L, The study concluded that an economic analysis of the construction costs amounted to 110 thousand dinars and important recommendations for the use of this technology .
