Abstract
Wastewater treatment and sanitation is a major issue in protected environment and health in many countries in the world especially in the developing arid and semi-arid countries where water sources in all countries are rare and a source of conflict. Sustainable wastewater treatment systems may provide sustainable none conventional water source if operated and managed properly. There are national and local organizations work on monitoring water services regularly, assignee indicators to measure the effectiveness of the service, other organizations follow up the service after implementation "post-implementation monitoring". As there is no clear process for evaluating and selecting the appropriate technology commensurate with the community's capacity and needs. As such, the limited knowledge of decision makers has led to choosing unsustainable solutions as 65% of projects in developing countries fail in their early stages. However, many studies and research indicated that focusing and studying the community increases the community ownership of these projects by including the community capabilities and needs in the stage of choosing the technologies. Thesis aims to develop classification model for wastewater treatment plants to be compatible with community capacity to reduce the failure in sanitation systems. With this model, the decision makers will have the ability to examine and scale the problem according to their requirement.in this research (Bouabid and Louis) methodology will be use based on analysis eight main capacity factors to evaluate and asses the community and wastewater treatment technologies and chose the most appropriate technology that compatible with the community. Most of sanitation technologies failed after a short period because of the bad monitoring after implementation of the project finalized because of not tacking inconsideration the community characteristics, and capacity factor. Several researchers try to find the best fit of choosing a propriety technology but after selecting the technologies, many options appear and with the same level leading to a selection of many none specific technologies, leading to none sustainable treatment system, in this research some parameters will be added to reduce options depends on the needs of the treated water and the its source. The geographical extension and the sparse population of the Palestinian territories lead to an exhausting challenge for governments to establish centralized wastewater treatment plants for its communities; in addition, 65% of Palestinian territories are area C where it forbidden to establish centralized WWTPs. Moreover, the lack of sewage networks and the economic crises lead to consider the WWTPs with low operating and maintenance costs, as well as the least consuming land and energy, are the most appropriate options so that these communities have the ability to manage and operate these stations.
