Rainwater harvesting in Raipur, Chhattisgarh : Precautions to be adopted in the storage and use after 6 months


I am a student of N.I.T. Raipur (architecture branch). For my thesis I am working on rainwater harvesting system for a colony in Raipur. I would like to know whether storage is a good option for later use or recharging. And if water is stored what precautions/methods will have to be adopted to maintain water qualityfor use after 6 months.
