Contribution to the evaluation the effectiveness of different domestic potable water storage systems in ensuring water quality and safety through a questionnaire-based study (case Tamanghasset city- Algeria)

Water is one of the most important conditions for survival and prosperity. With the years, the population growth and the increase in consumption of water sources that suffer from scarcity or rarity of rain, man has become obligated to develop methods store it. Nowadays, drinking water storage takes place in near-house or in-house tanks.

The impact of the domestic storage of drinking water on water quality, factors such as material composition of tanks, storage conditions, and maintenance practices were examined to determine their influence on water quality. Through study the behaviour of the region's residents; findings suggest that certain storage systems exhibit inferior performance in maintaining water quality; when we found many of sources and the health risks caused by non-compliance with health storage conditions. We found that the use of water from the water supply network is limited to daily cleaning operations, and they collected it in water storage containers, due to the varying availability timing of tap water.
