Abstract

The sanitation situation in the remote Villages in the Delta Egypt is becoming not only huge Environmental crises but also a crucial health problem. The problem lies in the rising of G.W.T due to the old used systems of disposal (bottomless cesspool "trench"), the waste water is mixing with the G.W.T and causing its rising to the extent that it floods the streets in some cases. One of the solutions that was considered was stabilization ponds, another was Extended Aeration (activated sludge). As new concept the Japanese university introduced Down Hanging sponge as an experienced solution for the task. For many years, decision makers for sanitation in Egypt built their decision upon initial cost only, neglecting the other long term costs like running cost and operation and maintenance and other factors affecting the treatment processes. Then, when fundamentals of Value Engineering science were introduced, thinking began to change. Now after the development of Environmental Engineering science, other factors that may affect the decision-making process, like sustainability, surrounding impact, the assessment, manipulation of environment. Moreover, other social factors were neglected like people habits and what effect that could have on them in daily life. Their ability to manage every system in case of decentralization, the contribution of Different stake holders that effect the management of every system especially in decentralization, those factors could be essential in any study. This study focuses on these new parameters and to translate them into numerical values to help the decision makers to make a better judgment and to reach the most practical decision needed for sanitation and water treatment in small villages in Egypt. The study of Environmental Impact Assessment (EIA) is becoming urgent and more relying on management techniques such as risk analysis, creating weight score matrices for different variables surrounding the Environment of the different treatment plants in each case depending on the location, the cultural habits of inhabitants, Socio economic impact assessment, Sociological impacts, Ethical considerations.
