For how long could i store water without cleaning storage/ network?

water is stored without cleaning storage network as maximum 7 days, after 3 days the water coposition started to change. in the atmosphere a number of gasses and imputies so if we want to store water we break the atmospher contact with water.

First, Ensure the sterility of the storage and cleaning of the net before use. second, if it is a chlorinated water, it might be stored for 1 week. Clean the storage monthly. Always check for smell and taste. Avoid the storage from direct sunlight and heat.

Water should be stored for atleast one month to avoid bacterial growth if the residual chlorine levels in them are low or non-existent.After that one month,the storage tanks should be cleaned thoroughly.
