Drinking water has received considerable attention recently. However, misuse and mismanagement have resulted in a rapid and widespread decline in source-water quality and supply. Water quality guidelines can be used to identify constituents of concern in water, to determine the levels to which the constituents of water must be treated for drinking purposes. Membrane technology for the water cycle is playing an important role in the provision of safe water supply and treatment. The aim of this paper is to conduct chemical and microbiological analysis of water samples. The need for standards and guidelines in water quality stems from the need to protect human health. The results revealed that there were several areas polluted chemically by some heavy metals (Ni, Cd, Pb, Mn and Fe) and microbiologically by (Entamoeba Histolytica, Amoeba, Egg of Nematodes and Total count of Bacteria). We conclude and recommended that water treatment could see better membranes with both higher permeability and tighter cutoff. Removal of some chemical constituents must be done and sewage system projects are implemented in all towns and villages.
