Question

How rainwater harvesting can be done at domestic level?

Answer 1

Rainwater tanks in your backyard.

Answer 2

"DomesticRainWaterHarvesting systems vary in complexity, some of the traditional Sri Lankan systems are no more that a pot situated under a piece of cloth or plastic sheet tied at its corners to four poles. The cloth captures the water and diverts it through a hole in its centre into the pot. Some of the sophisticated systems manufactured in Germany incorporate clever computer management systems, submersible pumps, and links into the grey water and mains domestic plumbing systems. Somewhere between these two extremes we find the typical DRWH system used in a developing country scenario. Such a system will usually comprise a collection surface (a clean roof or ground area), a storage tank, and guttering to transport the water from the roof to the storage tank. Other peripheral equipment is sometimes incorporated, for example: first flush systems to divert the dirty water which contains roof debris after prolonged dry periods; filtration equipment and settling chambers to remove debris and contaminants before water enters the storage tank or cistern; handpumps for water extraction; water level indicators, etc. "

I hope this helps you ^^

Answer 3

You could get a water storage tank and make the gutters and pipes on your roof lead into it.

Answer 4

I've got two rain barrels in the garden.  One gets fed by a flap in the drainpipe running down from the guttering on the house, and a second one has a similiar relationship with the guttering on the garden shed.
