Effect of Water Storage Tank Material on Quality of Water with Storage Period

Abstract

Quality drinking water is of prime importance for human need. Potable water comes from surface water and groundwater sources and it is acceptable for human consumption. The method of storing water plays a crucial role in maintaining its purity and safety for human consumption. Due to lack of continuous water supply, storage tanks are necessary to store water and storage tank material may affect the quality of potable water. The objective of this study is to investigate the variation in water quality during storage for some particular time period in different types of storage containers. 40 days (six weeks) is considered to determine potable water quality variation during storage in different container materials and materials used for containers are plastic tanks, clay pot and Reinforced Cement Concrete. To find the water quality parameters, samples are to be collected at five days interval. During the period of storage, physical, chemical and biological water quality parameters are to be determined. Parameters obtained from above tests are analyzed to understand the effect of age and container material on the quality of potable water. This analysis is useful to choose the material of storage container to store water for a particular period of time.
