Treatment and potability are essential properties of water to be considered in the design and construction of a water treatment plant model. The quest for treating raw water is important in areas fac ing acute shortage of potable water. This study examined how raw water can be treated via the use of a treatment plant model. Glass, silicon sealant, diamond glass cutter, Measuring Tape, Abro2000(USA brand) stoppers, glass drilling machine, pipe and hose, aggregates and glass cleaner fluid were used in the construction of the water treatment plant model. The raw water samples were also collected from a moving stream near sewage plant at the Polytechnic Ibadan Oyo state, which was then, treated using the water Treatment plant model. The raw and treated water were characterized by carrying out laboratory analysis on the samples, the analysis were carried out at Kappa Laboratories Bodija Oyo state, Nigeria. The physical (Colour), chemical (COD, Total dissolved solid and Calcium Hardness) and microbiological (Coliform) Properties of the water samples were then tested to determine the potability of the water samples based on the model designed. Raw and treated water samples’ laboratory results were compared with the World Health Organization (WHO) standard to ascertain if the treated water is suitable for both Industrial and Domestic consumption and the results were clearly stated as follows; Untreated/ Treated ; Colour (3.3hazen units)/(0.5hazen units), COD (36.6 mg/L)/(2.8mg/L), Total Dissolved solid (622mg/L)/(165mg/L), Calcium hardness (66mg/L)/ (58), Coliform (2.2x102 CFUc/ml)/(Nil). The water treatment plant model harnessed the potability properties of the raw water thereby producing water suitable for human consumption. The treatment plant should be used in Areas faced with lack of potable water. Keywords: Treatment plant model, Portability, Coliform, World health Organisation, Microbiological Analysis.
