Every drop is precious!
Spot your location here to find average rainfall in your area
This is the amount of natural, untreated distilled water that you let go down the drain, every year. In fact, you have been fetching chemically treated municipal water from the taps which most often interferes with good health and body. Not just this, people at many places pay decently to get bottled water for drinking purposes. All this in spite of the fact that we receive almost pure water in decent quantities from the skies.
It is never too late to start!
You have a decent catchment area, water from where can easily be used directly for ablutions, cleaning or watering the garden or fields. If collecting with proper sanitation, and there are not effluents releasing industries within 10 km of radius, this water is good enough to be used for drinking or cooking after boiling.
How to reap?
At places with ongoing water crisis, people never wait for a plumbing project at their home to inaugurate their Rainwater harvesting setup, they just start fetching it right away. Spot a catchment area for instance your roof, and clean it thoroughly before the expected rains. in most houses of old construction a drainpipe from roof drains rainwater to the ground or into the storm drain . Clean the drainpipe by passing a threaded sponge through it. Connect a hose to the outlet of that pipe and let that hose drain water into a barrel.
A barrel is hardly 50 liters, after calculating you rainwater potential above, you must be aware that a barrel is too small to carry the abundance raining from the nature. But as this is a makeshift arrangement we can reap whatever we can through this method.
Please try this easy way of rerouting water back to ground or into a harvesting tank via retrofitted systems as discussed below.
For the houses that have already been constructed, a rainwater harvesting system can easily be retrofitted depending on the requirement. For instance a simple extension to makeshift system above may consists of a down-pipe filter connected to a storage tank. A pump is then installed to supply this stored water for rainwater fed connections like garden tap, washing area, flush etc.
