Alexandria City is the second capita of Egypt. The problem of interior immigration to Alexandria adds various problems to the available residence area. Slum areas are gradually formed and distributed around the circumference of Alexandria City. The aim of the work is to evaluate the sewer system in these areas, Alexandria Governorate. Slum areas suffer from the absent of sewer pipe system. A survey was conducted for slum areas in three representative areas were selected and applied to three different alternatives aiming at installing new sewer systems using different financial schemes. The selected areas were visited, studied and its sewer systems were evaluated. Three new sewerage projects were designed for each area. The construction costs of each project were calculated. Administrative and financial schemes were settled. Also, three Septic tank is the only means of wastewater disposal in slum area. Miserable sanitary condition was found in the selected slum Wastewater is flooding over the road level due to high population density and due tole areas, septic tanks malfunction. Some slum residences fill the road at the front of their homes with soil. Others construct privet sewer pipelines. These sewer pipelines did not follow any engineering standard. Also, these pipelines are malfunctioned due to pipes flat slope, small diameter, and limited capacity. Most of the manholes are uncovered. Regular maintenance is not made. The government has to provide funds to implement projects of proper sewer systems in slum areas. However, funding these projects is not available. The government should, at least, provide a funding mechanism and administrative schemes as an alternative to implement these projects. People in slum area can afford zero interest governmental loans for ten years, but they cannot afford repaying the revenue of BOT projects.
