There are severe water rationing practices that have resulted in consumers opting for storage than waiting for the next supply. This storage in turn has its effects on the water distribution system of a community.
Thanks for bringing this up. Besides the quality concerns, storage is seen as a compensatory strategy by households to accommodate with supply deficits. I think it has both, social and economic perspectives.
The economic aspect is the main determinant to adopt this strategy. This means that high consumption is more likely expected from storage tanks' owners.
More importantly, this can mislead policy makers in measuring the social equity of the water system, which harms planners interested in sustainable water systems.
