Demand Solar has improved a scheme of twice filtration so unclean water trapped in the filter can be sent back to the pool dirt free or gathered in an other tank for use again at an later date. When regular backwash happens as much as 1,000 litres can be flushed away into the drainage system.
Throughout the use of this system, water that would in general be deserted to garbage following rain can be stored and later on recycled for topping up the pool or watering the garden.
As the pool water is being cleaned on a daily basis and treated with only depleted levels of chemicals, the returned water will not distress the equilibrium of the pool or the soil.
