Suggestions please...low water table + well problems

11/29/2012 - 04:58

The water table in the whole Sabina area is (according to a local geologist) lower than it has ever been thanks to less rain than usual last autumn/winter/spring and the record temps of last summer. Sadly this means my well has more or less dried up (approx 1m of water in it, but too little to pump), so I have now been without running water for 3.5 months! Not fun!!! Like many country properties in Italy, there's no mains water here and it would be far too expensive to hook up to the system so a well is really the only option. I'm collecting cannisters of water every day and a friend is kindly doing my washing and offering use of the shower from time to time, so it could be worse!I'd just like to know if anyone else has experienced this problem and how they resolved it!The well, it turns out, is not that deep (just 35m) and I've been told that it could take 4-6 months for the water to return and only after that period of time should I start assuming that water will not return ever because of a collapsed vein or whatever.Also been told that this existing well cannot be made deeper as it does not have a stainless steel lining, so it will mean starting from scratch.As a temporary and back up measure, I'm trying to sort out harvesting rain from the roof / gutter - local builders etc look at me as if I'm mad - my idea is to pump the collected water from the tank at ground floor level (so that I can fill it with cannisters of water too if necessary) and send it up to the tank in the loft... Any suggestions??Many thanks!

... sorry, but at least this is a very good warning to others coming along to this site with a view to buying... Water is not a particular problem here, but not too far further from here it is, despite there being lots of recent heavy rain. The hot summer we had will hav 聽an effect for many a year yet I think... Sure you are already conserving water, but I suspect if another well is not possible, then buying water and conservation is the only solution. Do think your idea of surface rain collection is worth looking at. Our neighbour (old italian guy) has all of his down pipes going to his 20m concrete lined well (depsite having mains water, so obviously water is/has been a problem here in the past). Not too sure if he uses it for anything other than watering the veg mind... Unfortunately whatever needs doing will likely be quite costly - best of luck.

How far away is the mains supply? I know someone who had a very deep well drilled with no trace of water, but then had 1.5kms of new pipe laid from the mains to the house. Expensive, yes, but would solve the problem if you had now water in the middle of winter and a tanker could not reach you.

whilst,of course you can dig wells (with permission)and attempt storage of rainwater all of which are commendable and useful i don't really think that one can run a "modern" household without mains water whilst at the moment we do not have the extreme problems of the sabina here we are miles from anywhere and had mainswater put in.IF you are a permanent resident one pays a subsidised amount which whilst not cheap is not eye watering but if it's a holiday/second home etc it does get quite expensive聽 having said that it is or would be important for the value of the house when and if you ever wanted to sell it if it already had a mains connection....worth getting a quote from the water company anyway rather than relying on heresay of what is expensive

Hope it does start up again Sabina. May be worth investigating putting in a pump to send it to a store when the water level improves. Do not know how much a storage tank would cost though, plus you must make sure that the water is filtered and boiled before using.

If the problem is widespread in your area, then you (and everybody else) should get together in an attempt to force your water authority (via the comune) to make some provision. If they can lay a main which will serve a village or two, and from there perhaps groups of outlying houses, the cost - though likely to be considerable - could come down to affordable. You must ask the right people - certainly the comune would be the place to start - and obviously the more requests the more likely would be any chance of suceeding. It might take a few years, but the right to potable water was recognised by the UN as a fundamental human right about ten years ago - and yes, it is going to cost Italy a lot to fulfil this promise, but that doesn't mean you should give up on the hope of them delivering it.

Sabina - I once did a model comparing usage vs. local rainfall patterns and found that for a family of 3 we'd need about 30,000 litres to store the roof production.... needless to say this does not go in the loft as it's about half a swimming pool. There is usually a local geologist to track down and ask about well siting and depth ... the guy who comes with the twigs is good for a laugh but seems to point to the place where it would be easiest to park the well digging truck.... try to keep a straight face when he swings the bob to show the depth.

To say that you cant run a modern hosue without mains water is rubbish. 聽There are millions of people in ITaly who do not have mains water, the important thing to remember that water is a resource and not some freeby that arrives down a tube for your swimming pool.聽 It is however, not cheap - if you ar starting from scratch the best thing is to install a cisterna when you do the bubild or restoration - these can be up to 50mc and will store rainwater and/or delivered water. 聽If that isnt possible, then large serbatoi can do the job - dig a hole and bung them in - at least 10.000 litres. 聽聽 If you hvae no water then the comune has bowser supplies - obvioulsy you pay but it isnt that much more than metered water, and they deliver 10.000 litres a time into your underground tank. 聽聽 You say your well is dry - I assume you mean its an old hand dug well - yes you would need a steel lining - depending where you are - you can also use pvc in alot of areas which costs alot less - that would allow you to deepen the well and go down as much as you need, assuming that the fallia still exists - 'Ripristinazione' of old wells doesnt need a difficult permission - and alot of people use this as a guise to dig down a bit further, but if you are going to sink a trivella (a drilled well) you will need a permission. 聽 AS you pay per linear metre its difficult to work out how much it will cost you - for the drilling, the sleeve and then for the pump. 聽 In your position I would sink a couple of big tanks 聽and see what happens with the well water - it may well be that you end up with water int he winter and spring and nothing in the summer - if so you'll just have to learn to get by, but loads of 禁漫天堂s do just that
