    CWatters I have one other question about this system (which incidentally I like very much).

    If this system was providing water for the toilets of, say, 10 houses, would you keep the lower half of this tank permanently full of water (with mains water) to meet those demands? How else would the toilets fill up after a prolonged dry spell?

    Also do you need to be cleaning the water in any way before using in toilets?

    I've just picked up on this thread, I've been looking at others concerning RWH and water treatment.

    I would like to add something of my own experience regarding the provision of an overflow from the tank. We have just installed an underground tank and were looking at what to do about any overflow. The tank is close to a new run of sewer pipe but the building regs. chap would not permit us to discharge into the sewer, even with a non-return device. We did not wish to dig a soakaway (part of my argument for a RWH system was that it was cheaper to dig the hole for the tank than construct a soakaway 5m from the building; doing both would have been fatal!). Anyway, the chap in building regs. was happy for the overflow to go into a perforated pipe running along the garden, which was pumped from a second chamber (manhole) next to the tank.

    ...sorry, had to go.

    This does, however, mean that we are running two pumps.

    Could anyone point me in the right direction with regard to using the rainwater for showering. Are there any regs. pertaining to this? Thank you.
