Or perhaps better to ask,<span> <\/span><span>what kind of water is it?,<\/span><span> <\/span>Is it from the municipal mains, where there is a fault? Is it sewage from a fault in a building or a nearby wastewater outlet? Perhaps from a nearby aquifer? Or, if we are close to the coast, from the sea\u2019s own water table?<\/p>\n<p><b>Knowing where it comes from is essential<\/b>, and not only to focus the search for the leak and its repair, but also to know what legal action to bring, because the type of water will reveal its origin: it may come from the water distribution network (possibly a matter for the public authorities), from the water table (civil claim, architect), or be the responsibility of another building (civil claim).<\/p>\n<p> In any event, and as a consequence of all this, given the evidence of the serious defects that have appeared, the Architect who drew up the Basic and Detailed Design should have taken the measures needed to prevent this serious defect, -which was foreseeable,- which is seriously compromising the<span> <\/span><b>stability of the building\u2019s foundations and structure<\/b>, since they were undoubtedly built without proper waterproofing, in view of the obvious damage that has occurred.<\/p>\n<p>But how can you tell what kind of water it is, easily and quickly?<\/p>\n<ul>\n<li><b>Buy a syringe and a sterile cup<\/b><span> <\/span>from the chemist\u2019s.<\/li>\n<li>Go down to the basement yourself, draw some water and put it in the sterile cup.<\/li>\n<li>The water in the basement and in the lift may come from the same place and be the same water, but it is not advisable to open the doors and go down into the lift pit without the involvement of specialist lift personnel.<\/li>\n<li><b>Have the water analysed<\/b>.
