Abstract: The most extremely northern part of Nile Delta suffers from the shortage of water for irrigation purposes and reuse the waste water (sewage, industrial and agricultural drainage). The farmers of this region obligate to reuse the waste water in planting especially in summer seasons where rice is planting. The objective of this study is to evaluate the quality and variations of chemical composition (cations, anions and heavy metals along a year; May 2004 to April, 2005) of sewage water from upper drain No. 7, Kafr El-Sheikh city. To achieve this objective 365 sewage water samples were collected daily for a year near Messer in which Kafr El-Sheikh city discharge their municipal sewage water.
Chemical analysis indicated that:
* pH values of studied sewage water were slightly to moderately alkaline and have moderately salinity levels and low sodicity parameter i.e. quality assessment was class C2S1. Sodium cation was the dominant followed by calcium and magnesium. On the other hand, chloride and sulphate were the dominant anions.
* Heavy metals arrangement according to seasonal variation: Cd arranged as follows: spring > summer > autumn > winter while Pb and Fe contents arranged in the order: spring > winter > summer > autumn. The contents of Ni, Cu and Mn arranged in the following order: winter > spring > autumn > summer.
* Heavy metals concentration of the studied elements arranged according to their contents in the following order: Fe > Pb > Ni > Mn > Cu > Cd.
* Concentrations of all studied heavy metals in sewage water were higher than the permissible limits of FAO (1985).
* Consequently, series measures and treatments should be unplemented before reuse of sewage effluent in irrigation purposes
