The increasing demand for clean drinking water due to the growing population has led to the upsurge of private water supply companies. Consumption of pipe borne water and from other untreated sources has resulted to outbreak of numerous reported ailments. This prompted several studies on water quality assessment and availability including this study. This study assessed the quality of water produced by different water supply companies. The physicochemical parameters and coliform were assessed using standard chemical and biological analyses respectively. A total of 30 sachets water were sampled from Zaria, Giwa and Sabon Gari Local Government Areas in Kaduna state. The results of the quality parameters; turbidity, pH, BOD, DO, Electrical conductivity were in a range of 0.61 - 2.06 NTU, 7.10 - 7.40 mg/l, 1.20 - 2.02 mg/l, 2.70 - 3.90 mg/l and 125 – 215 µs/cm respectively. Although, the values varied with respect to each parameter, all were found to be within the safe limits of the Nigeria industrial standard (NIS) 6.5-8.5, 100mg/l, 50 mg/l and 1000µs/cm. However, the values of Pb was found to be 0.19 – 0.23 mg/l in some water samples obtained in Zaria which is slightly above the permissible limit of 0.01mg/l WHO/NIS standard. Similarly, the results revealed the presence of some coliform bacterial in some same samples obtained from Zaria and Sabon Gari. From the results of the study, it showed that the treatment techniques adopted by most water supply companies were not effective and thus require significant improve in order to meet the national drinking water quality benchmark. It is recommended that to ensure clean and safe drinking water, strict adherence to the hygienic standards and safety guidelines set by Nigeria Industrial Standard (NIS) shall be observed. It is also recommended that adequate and enough treatments be done to reduce the coliform count to zero before consumption.
