As much as my past business was focused on solar thermal and thermal stores, I was also very concerned about the water every home owner and those in rented acomodation wasted

So this is the start of a new folder, after our hottest summer to date and with very little rain fall to see us through to the winter

Today I serched for UK made water tanks and liked what DIRECT WATER TANKS was offering

You can find them on www.directwatertanks.co.uk

They sell a 1,000L tank in a suport frame for just over £200 + Vat including delivery within the UK.
Over the next few weeks, I will look to break down how my own system works at my home in Wimborne Dorset, so everybody can follow
To fill this tank with rain water you need a water butt attached to a in line down pipe harvester, to direct rain water into the water butt.
In side the water Butt, you install a submercible pump with a float attached.
As the butt fills up to a level below over flow, the pump switches on and pumps the water into the bigger tank/tanks
From the outflow valve at the bottom, you need to connect a 2 inch pipe from where the tank is located to inside a shed, where you then need a boaster pump to be located.
With the boaster pump supplied with rain water, you then need a pair of filters to filter the water if you use for house use. Like flushing toilets, washing up or as I do have a shower heated by solar, with 2 more storage tanks in my loft with another boaster pump.
If you want to use just to water garden as if was mains pressure, forget the filters.

I will be adding much more information and greater details of my own system, I first installed in 2000, after I purchased this new 3 bed house, useing one of these tanks I imported at the time from Cyprus.
