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 improve the water quality, to be valid for domestic purposes, through minimizing the health risks associated with either direct or indirect use of water. 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 recommend that water must be treated with better membranes, with both higher permeability and tighter cutoff. Removal of chemical constituents must be done, and sewage system projects should be implemented in all towns and villages.
