Untreated sewage disposed in Nablus imposes serious health hazardous on people and environment, it is necessary to treated and reuse it. Sewage water includes many kinds of pathogens that cause diseases and maybe become fatal and cause death. WHO estimate the number of death every year cause by waste water is nearly 1.5 million. Because of the effects of this problem is increased, there is need for intensively offer to suggest solutions to reduce problem by WWTP design and implementation as possible as soon. WWTP is environmental friendly to deal with wastewater, sludge, solid waste. Plant location at the east of Nablus city on wade AL-Sajour , the source of water from Nablus east and eastern villages . Wastewater is water that has come into contact with any of a variety of contaminants and is not fit for human consumption most often; wastewater has its source in domestic settings, commercial operations, industry and agriculture ( Sewage not suitable for human use, it is need for treatment. Treatment is the process of removing contaminants from wastewater and household sewage, both runoff (effluents) and domestic. It includes physical, chemical, and biological processes to remove physical, chemical and biological contaminants. Its objective is to produce an environmentally-safe fluid waste stream (or treated effluent) and a solid waste (or treated sludge) suitable for disposal or reuse (usually as farm fertilizer). Using advanced technology it is now possible to re-use sewage effluent for drinking water, although Singapore is the only country to implement such technology on a production scale in its production of Neater. The treatment of wastewater is relatively modern practice .Although sewers to remove foul-smelling water were common in ancient Rome, it was not until the 19th century that large cities began to understand the necessity of reducing the amount of pollutants in the used water they were discharging to the environment. The objective of municipal water treatment is to provide a potable supply _ one that is chemically and microbiologically safe for human consumption. For domestic uses, treated water must be aesthetically acceptable free from apparent turbidity, color, odor, and objectionable taste. Quality requirements for industrial uses are frequently more stringent than for domestic supplies. Thus, additional treatment may be required by the industry. (HAMMER, 2008) Nablus is a Palestinian city in the northern of west bank with population 126,132 capita.Located in a strategic position between Mount Ebal and Mount Gerizim; it is the capital of the Nablus Governorate and a Palestinian commercial and cultural center. Founded by the Roman Emperor Vespasian in 72 CE as Flavia Neapolis, Nablus has been ruled by many empires over the course of its almost 2,000-year-long history. In the 5th and 6th centuries, conflict between the city's Christian and Samaritan inhabitants climaxed in a series of Samaritan revolts against Byzantine rule, before their violent quelling in 529 CE drastically dwindled that community's numbers in the city. In 636, Neapolis, along with most of Palestine, came under the rule of the Islamic Arab Caliphate of Umar ibn al-Khattab; its name Arabicized to Nablus. In 1099, the Crusaders took control of the city for less than a century, leaving its mixed Muslim, Christian and Samaritan population relatively undisturbed. After Saladin's Ayyubid forces took control of the interior of Palestine in 1187, Islamic rule was reestablished, and continued under the Mamluk and Ottoman empires to follow. Following its incorporation into the Ottoman Empire in 1517, Nablus was designated capital of the Jabal Nablus ("Mount Nablus") district. In 1657, after a series of upheavals, a number of Arab clans from the northern and eastern Levant were dispatched to the city to reassert Ottoman authority, and loyalty from amongst these clans staved off challenges to the empire's authority by rival regional leaders, like Dhaher al-Omar in the 18th century, and Muhammad Aliwho briefly ruled Nablusin the 19th century. When Ottoman rule was firmly reestablished in 1841, Nablus prospered as a center of trade. After the loss of the city to British forces during World War I, Nablus was incorporated into the British Mandate of Palestine in 1922, and later designated to form part of the Arab state of Palestine under the 1947 UN partition plan. The end of the 1948 Arab-Israeli War saw the city instead fall to Jordan, to which it was unilaterally annexed, until its occupation by Israel during the 1967 Six Day War. Today, the population is predominantly Muslim, with small Christian and Samaritan minorities. Since 1995, the city has been governed by the Palestinian National Authority. In the Old City, there are a number of sites of archaeological significance, spanning the 1st to 15th centuries. The city is known for its kanafeh, a popular sweet throughout the Middle East, and soap industry.
