Abstract : There is no doubt that intermittent water supply in vast areas of Jeddah led the people to construct underground water tanks to meet their needs. Also, the lack of sewerage systems in large areas of the city forced the people to build cesspools near the underground water tanks. These factors made drinking water in underground water tanks subjected to contamination. Within the intermittent water supply, the pipes are empty and dry for long periods. The potential leakage of seawater intrusion into the distribution network and the underground water tanks are very high and pipe system expose to the pressure of contaminated surrounding groundwater. The need to conduct a research to monitor the quality of drinking water in residential buildings in Jeddah is necessary. The first objective of this study is to assess the quality of drinking water in Jeddah residential buildings. One hundred and thirteen water Samples were collected in a five-month period and were analyzed in the laboratory. Thirteen parameters were evaluated and compared to the maximum level of the WHO and Gulf standards for unbotteld drinking water. The results showed a compliance with the drinking water standards regarding the physical and chemical parameters, except five samples which have exceeded the maximum allowable limit for Iron. The bacteriological results showed that up to 60% of the samples were contaminated with total coliform. The second objective is to evaluate the suitability and reliability of the domestic water purification units point-of-use (POU), and to select the suitable water purification unit for the residential water in Jeddah. A controlled experimentation was conducted on the four most used filters, for the following parameters: turbidity, electrical conductivity, pH, Iron, total coliform and percentage of wasted water. The main finding was that large amount of water (up to 66%) was wasted in (reverses osmosis) filter (unite II) and stripping of beneficial elements in the incoming water. Also (unite III) which consists of fiber filters, activated carbon filter and the ultraviolet UV- Sterilizer was found to be suitable for domestic water in Jeddah.
