Can anyone recommend: Water supplier via tanker

Good day to you all.  We are relatively new to the area and have a villa some 15 kilometres South of Velez Rubio.  We are not connected to mains water and have been having our water delivered by tanker which up to very recently has not been a problem.  We are now however having difficulty is contacting our supplier and are looking for an alternative source, do any of you know of any water suppliers?  Many thanks n advance.  Andy
