well basically. I have a hipped roof on a detached dormer bunglow. I used oil storage tanks. I bought them cheap on line to harvest the water. I am storing with tanks joined together approx 7500 liters each rain cycle. I fitted a sump internally, however designed the inlet of water in a way the water does not become stagnant. I have the tanks hidden in a timber out building. (for a cosmetic finish)
I have 1 outlet from the hipped roof gutters. the rain passes through a diverter into the tanks via that outlet. the sump then passes the water via a filtered system I made (also in the timber out building). then feeds the toilits & garden tap and washing machine directly via pipework at approx 2.5 bar pressure.
If it was a new build I would have buried the tanks and left an inspection lid for maintainance. BUT WORKS PERFECT AND IM HAPPY WITH the COSMETIC FINISH. I have a meter on it and at present I am getting a cubic meter of water free every 3 days. (cubic meter = 1000 liters)
it took myself 2 days to install. that included re plumbing the wc and toilits. It was quite easy. But then again I have done a course on these systems and have an m&e back round. I done this as a project to show protetial clients in the future. However I recon a similar system I would be charging approx 6000 euro. water rates with an approx price of €2.40 per cubic meter and my usage at present. The payback time is in excess of 15 years. The system would also need an annual service.
It really depends on the cost of the water in the future. The eu directive is clear, the cost of supplying and treating water to the domestic market must cover the 1 billion cost. So the €2.40 figure. I am using as a price per cubic meter is probably not realistic. (This is approx cost in Great Britain.) Maybe we will be paying anything in excess of 8 euro per cubic meter in the near future. I think we will.
there is many ways to design these systems. however regardless of the type of system. If the system is not a gravity designed one. The rainwater storage I would prefer buried under ground.
