Abstract: Polymeric pipes have become the most dominant type of pipes used in water distribution systems (WDS). There were not enough studies conducted on the impact of desalination on the WDS. The effect of polymeric pipes on the quality of desalinated water is rarely explored. This research aimed at studying formation of trihalomethanes (THMs) for desalinated water through polymeric pipes. Three pipe loop systems [polyvinyl chloride (PVC), polyethylene (PE) and polypropylene (PP) pipes] were designed to study the impact of pipe material, organic dose, and concentration of calcium hypochlorite on formation of THMs. Results of the 33 full factorial designed experiments showed a strong correlation between pipe material, organic dose, and calcium hypochlorite and THMs formation. Occurrence of bromine and chloride could shift the distribution of THMs among the three different pipe materials used in the experimental setups. This research highlighted the effect of polymeric pipe material on water quality.
