Using Descriptive Statistics Style treated the study, by data entry into SPSS computer program. And the results were as follow:
- The averages of individual’s water consumption in Nablus city show low rates, this thing reflect the quality and concentration of Wastewater. - The Biological Oxygen Demand “BOD" (Pollutant organic) resulting quantities show the highest rates at olive presses. - Economic, social, population, & demographic characteristic somehow affect the quantity of Wastewater.
- There is a clear difference of the Wastewater qualities through the year seasons; organic materials and pollutants are less concentrated at summer, since the average of individual's water consumption is low.
- Small families owning several bathrooms and automatic washers and other sanitary equipment show the highest rates of water consumption.
- Industrial wastewater is considered the most dangerous pollutants of the water sources in the region, and its leakage to groundwater will diminish the reserved quantities of the region.
