    hi, i am looking for ideas, info & if poss reccomendations on what to buy or make for how to make rain water safe to drink for the family.

    we are looking to maybe buy somewhere with no supply, i know we can collect absolutely loads of rain water, probably more than we will need both for drinking & other stuff which makes me wonder? do we really NEED a mains supply?

    i googled & loads came up about filtering tap water for chlorine etc & a few USA companies & posters waffling on about their systems which often look like or cost like something from NASA.

    some claim just multi filter it, some say UV light zap it, some say do both, some just basic filter & boil.

    some systems are so expensive? would we be better using rain water for not drinking – just showers , washing machine etc & buy bottle water to drink?

    or is it best after it all to just bite the bullet & pay up for mains water?

    anybody done the rainwater way?

    bye

    We sometimes vacation “back to nature” in places with no mains supply and we use water purification tablets and have never had a problem, but that is well water not rainwater. We use the rainwater for some washing purposes but never for drinking or cooking.

    How are you going to collect it and store it and how are you going to stop it getting contaminated during storage? Does the property not even have a well? Most places that have no mains supply have a private supply from a well, or what did the previous occupants do? Well water keeps fresh, rainwater stored for a long time risks stagnation and stagnant water is a serious health hazard.

    If this is for long term permanent residence and you want a normal life then to be honest I wouldn’t even try to live without mains supply.  For a month or so as a break from real life it’s OK but when it’s time to resume real life it’s good to get back to civilisation because there’s enough other things to deal with and think about, that you want to be able to take for granted the basics such as a safe water supply.

    Presumably the property has a proper waste disposal system (septic tank?) because that is not optional.

    Even though an Australian study did not not substantiate additional health risks from drinking rain water, I read that drinking unsanitized rain water seems to be illegal in the EU. The reason for this might be that the EU is actively promoting the development and sale of such devices.

    I believe you still have to have water from wells etc. regularly tested to make sure it is potable.

    ” I read that drinking unsanitized rain water seems to be illegal in the EU”

    You are right Caxton, or at least it is not allowed in France.

    There are all kinds of rules and regulations and obligations attached to collecting rainwater for household use, and (of course) fines if an inspector catches you not complying.

    https://www.service-public.fr/particuliers/vosdroits/F31481

    and

    https://www.service-public.fr/particuliers/vosdroits/F31482

    Basically you can only use rainwater inside the house for flushing the toilet and washing the floor, and if it’s been treated you can use it for doing the laundry. You have to put ‘eau non potable’ stickers on all the taps it comes out of, which have to be lockable, and you have to carry out and keep a record of regular maintenance (6 month and annual checks, cleaning and disinfection). Etc.

    So, looks like it is a no-no.

    Check with the mairie if there are rights of way to a well if nothing within the boundries of the house. As others have said drinking water would have been to hand in the past. Forget rain water unless it is for the garden.

    Not sure if there is a well? Get someone in with a dowsing rod to find an old well or and undergrond stream and dig a well or drill one. Lots of locals can use dowsing rods, including myself.

    I think that you may have a problem with your keyboard, as in english and french a sentence should start with a capital letter.

    I have said before, if somebody makes a textual mistake why do some readers find pleasure in pointing it out? Is it to show that they consider themselves to be more clever than the original poster? This is a forum not an English class. Mistakes bear no relevance if the remaining content is understood. I thought that this would not happen again since the past master of it has gone.

    So sorry caxton but I was just trying to help and like me it could be a keyboard problem. Oh I do not  think that I am clever, I wish that I had been and maybe much better off than I am now !

    I hope that the main part of my answer could be of some help as there are many underground streams.

    no problem with the keyboard Mic… just me using lazy english. no offense taken.

    thanks to all who put forward info, the situation was we considered building a new house & on a limited start-up budget we wanted to avoid paying out to begin with for things like a water connection, we intended leaving the connection to the last min, after raising the cash for it but then wondered if we could get away without it?

    we opted to concentrate on things that would stop us using the building at all like the fosse septique & roof!

    however the info + what popped up on google has decided us that if we go ahead it will be filtered rain water going into the hotwater system, washing machine & loo, with from the mains drinking water in the usual cold tap as per most ‘normal’ houses. this will still save lots of gallons of mains water waste & like the ad says ‘every little helps’, thanks bye

    “if we go ahead it will be filtered rain water going into the hotwater system, washing machine & loo, with from the mains drinking water in the usual cold tap”

    How about showers though? You can’t use rainwater for the shower. Nor for washing your pots. So your hotwater system would be unuseable for most of the things that people use hot water for.

    Flushing the toilet and washing the floor with rainwater is OK. Washing machine is OK if it’s been treated appropriately. Beyond that, outdoor use only.

    Do you have a certificat d’urbanisme? If so I think that mains water will be close.

    Yes, it costs a lot to get water in even if you dig the trench yourself. How far? Have you had an estimate? Could it be cheaper, in the long run, to have mains water?

    I use rain water for the veg garden and washing cars. Well water is going to be used for washing machine and flushing WCs. Hot water and drinking water is mains. The french system is that all cold taps are drinking water so forget the outdated UK idea of a cold tank in the loft.

    Sorry to say but a proper water supply should be needed in a new build and also in doing up an old building.

    Some locals have mains water but never use it, they just say that the pastis will kill any germs etc in whatever well or stream that the water comes from.

    Best to stick to the rules, for now, and do what you want in a few years !

    We don’t use rainwater, but our main water supply is a spring on the neighbours property that they pipe onto ours. we then pipe that 250 meters to a couple of black 1000l cubes, which is then pumped into our house through a string filter for showers  and cooking – for drinking this water is put through a Berkey  filter.

    We don’t have a septic tank as we use a composting toilet – we were inspected by spanc more than 5 years ago, and have heard nothing untoward from them since.

    Take from that what you will….
