The laboratorial tests of the samples water before distillation showed that the stream water contained T.P.C/ 1ml =2900 ( Total Content Of Bacteria ) , T.C/100ml >1600 T.C (Total coli form) , F.C /100 ml >1600 (Fecal Coli Formand ) and E. coli /100ml >1600 . The total percentage of salt in water trench before distillation was T.D.S mg/l 1886 \ After water treatment and distillation , the Total Content of Bacteria ( T.P.C) was decreased to T.P.C / 1ml = 210 , (Total coli form) T.C /100 ml = Zero , ( Fecal Coli Formand) F.C/100ml= Zero and E.coli /100ml = Zero . In and, the total percentage of salt after distillation T.D.S was decreased to 105 mg/l . The results of this research show that water distillation using solar distiller is a successful and efficient process led to decreasing T.C.P 93.8% and killing all types of harmful T.C , F.C. and E. coli bacteria. )By analyzing the samples of sterile water using the solar distiller in the laboratories of the Ministry of Health and Environment- Central Environmental Laboratory as shown in Table (6)).

Introduction With the shortage of water in different areas from the world , need of new techniques for treating unhealthy water and making it pure and can be used for drinking and other daily needs there became a An obvious improvement is seen in these techniques especially in terms of water distillation by means of solar energy and increasing the production of pure drinking water from different resources as sea water, water trench drainage systems and other sources [1]. The decrease of pure water and problems of drainage systems have bad effects on human health and are considered among the main risk factors which lead to various health problems. Thus, the solution of such problems lies in water purity, which means reduce the germs or bacteria that cause such problems [2]. One of the methods or techniques used in purification of water is distillation, which is
