Hi to All ,
can i chip into this conversation again ?
water storage is a major part of agri / horticulture around the world now a days , no doubt about it
now back to original question, using swimming pools waste water for crop irrigation ?
most people have the idea that pool water is thrown away after a few day in the swiiming pool ,
you are dead wrong ,
the water in the pool goes thru continuous filtration daily, and is reused forever,
so my friends you cant have enough water from pool to irrigate your fields,
and also if the pool is deeper than 5 feet deep it is dangerous to swim (children)
if you guy have the money built your own back yard pool , dont mix agri into leisure,
NOW ON THE WATER TANK FOR AGRI USE:
Based on my experience, in growing fruiting vegetable (tomato, brinjals,chillies,)
a plant wil need about 4 liters (when full grown) of water to have optimal growth daily (open air / drip irrigation method / insoil or poly bag)
if so ,
1 meter square of space will store 1000 liter of water right ?
if so an average small farm should have (say chilli plant ) at least 20.000 plant to make a little profit.
plus minus , your pump must deliver about 100000 liters of water from your source. (bore well ?)
and now to the water tank issue :
assume , during dry season , no rain , you must have the tank to HOLD water for minimum of say 1 month or so ?
and your duged up pond cant hold the water,
so , what you can do is probably,
dig out a pond like sized , 50 feet X 100 feet X 35 feet deep ,
and cover the walls with poly pond liners , which will hold the water and you can fill it from your bore well nearby,
dont use any concrete structure , its just too expensive ,
i have done it this way ,before and its practical ,
this method is very common in australian area.
also my friend ,
i am only sharing my experience , and i am not a consultant or trying to sell anything to you guys,
so , do your mathematics before you take out your money on any projects /
thats all for now folks,
