Summary:This research was focused on a comparative study of corrosion rate analysis during the winter and summer seasons of the water distribution network in urban Patna (Bihar), India. For the corrosion rate analysis, three test coupons were inserted into the pipeline of the distribution network during the winter season (November to March) and three test coupons during the summer season (April to August) for 45, 90, and 135 days, respectively. The coupon weight loss method was performed for corrosion rate analysis. During the winter and summer, the corrosion factors pH, temperature, conductivity, total dissolved solids, alkalinity, hardness, calcium hardness, chloride, sulphate, and dissolved oxygen were monitored on a regular basis. It was observed that the corrosion rate was higher during the summer than in the winter season. During the winter, the scaling percentage was higher than during the summer. The decreasing trend of the regression model indicates that water has a scaling behaviour that forms a protective scale.
