Nice article. Well written. I happened to notice it because I'm also one who advocates strongly to this (local administration encourages this method as there is water scarcity looming large esp during summer months). Hope you will find my article interesting too, if you haven't seen it before. Only last week I modified my filters and bought (see pic) a set consisting of the 'first flush' and the main sand filter, both in 12 gal. cans. I've connected it to our main sump where the water supply is also connected. I turn off the valve during the rainy season so that there is ample space for rainwater. We pump up this water into an overhead tank from where we use for all our needs. For our locality, good drinking water is supplied from the river bed (Cauvery - we are lucky that way) and so we find no need to use this water for drinking though it is potable after proper sterilization which some people do. We collect every day from the tap for drinking purposes presently. Supply is not yet hit by the scarcity.
