    TDS (Total Dissolved Solids)
    The readings that show on most TDS meters are parts per million. In simple terms how dirty it is. A low tds like say 50 for example is very damn good a reading of 200+ is really not so great.

    The readings will be different in different areas. I am in Cornwall and my reading is 95-100.

    You can grab a tds meter from here and many other places http://www.gardinerpolesystems.co.uk/cgi-bin/sh000002.pl?REFPAGE=http://www.gardinerpolesystems.co.uk/acatalog/catalogbody.html&WD=tds&PN=tdsez-water-quality-test-meter-by-hm-digital.html

    We have created a map here for users to show their readings so people get an idea in different areas. http://windowcleaningforums.co.uk/pages/ppmmap/

    TDS meters work by passing a very low electric current through the two prongs to measure the conductivity of the water. The lower the ppm reading is the less dissolved solids are in the water. Simples

    Yes, thanks, very interesting. I was looking on you tube people collecting rain water for wfp, so is it low enough to use without any further treatment?

    I would say no as even rainwater falling from the sky maybe good enough by the time it flows from a roof into guttering the rainwater becomes contaminated so ppm can rises quite high. For me I harvest it then the water gets past through pre filters then a di setup before being pumped into the van tank.
