Go traidisiúnta, tagann an fhoinse uisce ó fhuaráin nádúrtha doimhne ar mhórán mianraí nó ó thollhpoill trí shreafaí nádúrtha nó caidéalaithe, ach tá foinsí eile inghlactha freisin má tá cáilíocht mhicribhitheolaíoch ard oiriúnach ag baint leo (sprioc maidir le E. coli nialasach, lamháltas, 100cfu/100ml; sprioc maidir le listéire nialasach, lamháltas 100cfu/100ml, Salmonella nialasach, STEC nialasach) agus má tá siad saor ó éilliú uisce dromchla.
Traditionally the source of water has been from deep mineral rich natural springs or boreholes by either natural flows or pumped, however other sources are acceptable if of a suitably high microbiological quality (target zero Ecoli, tolerance,100cfu/100ml; target zero listeria, tolerance 100cfu/100ml, zero Salmonella, zero STEC) and free from surface water contamination.
