| Water is a major concern in(Palestine-west bank-rural area) since it's consider one of the poorest region of the Middle East in terms of water sources.Since the water is the life-as known- large sector of population of Palestine depends on agriculture field to survive them families, but, in fact Palestine nowadays(Gaza and West Bank) as occupied land suffering from severe conditions specially the shortage of water resources that affected all the life path, however, the demand on fresh water resources has increased with increasing population, thus we should find alternative resources of water such that wastewater treatment.The Palestinian Average water consumption in the West Bank for domestic, urban, and industrial purposes is approximately 73 liters per person/per day, this is considerably below the World Health Organization minimum recommended per capita standard for small rural households is 100 liters per day. On the other hand, Israeli per capita consumption average is 100-230 liters per person/per day.The wastewater sector in Opt has been neglected under Israeli occupation since 1967. While 31% of the total population are severed by sewage network system, a lack of wastewater treatment plants, of sewerage systems and wastewater collection for recycling, leads to the uncontrolled discharge of wastewater into the environment.Wastewater quantities generated yearly in the WB estimated at approx. 62 MCM annually a daily rate170 Ml/day including municipal, industrial wastewater, in addition to 35 MCM annually 96 Ml/day of untreated wastewater discharged by settlements and industrial zones into the WB environment.In Rural Palestine, the implementation of onsite wastewater treatment plants has focused during the last decade. Wastewater management in Palestinian rural communities is highly neglected, where they still depend on cesspits. In the last fifteen years, house onsite wastewater management systems have been blooming over the West Bank in rural areas. A fairly wide range of technologies suitable for onsite wastewater treatment plants have been developed. This thesis aimed to evaluate the technical issues of different technologies of onsite wastewater treatment plants with aspect to quality of treated waste water and the capability of reuse in agricultural sector.There are 13 existing collective WWTP, and 180 existing onsite WWTP located in the west bank, only 6.3%(2.836 MCM) of the generated wastewater in the West Bank is treated in the centralized and collective wastewater treatment plants, the remaining 93.7% is discharged untreated to environment.Treated wastewater reuse has an important significance to solve the water shortage, based on Fuzzy AHP method the quality of representative treatment plants are evaluated by referring to Chinese water quality evaluation criteria. It can help the Palestinian understand the current situation of sewage treatment and establish nationally appropriate water quality evaluation standard” system”.The results of analysis show that the treated water in level III, even though, it still need to strive to improve the sewage disposal technology, improve the processing of water quality, and expand the scale of sewage treatment, in response to the growing demand for water in Palestinian territories. |
