RAH Consultancy was requested by one of our industry colleagues to collaborate on a Water Regulations inspection of a large American Airforce base. It is US government policy to ensure that the water systems on their overseas bases are designed and maintained to at least the standards required in the USA.RAH first examined the differences between the US Code of Practice for the design and installation of hot and cold wholesome water systems and the UK Water Supply (Water Fittings) Regulations. Based on this study we recommended that the highest level of regulation from both the US and the UK would be used during the inspection.RAH then advised and oversaw the Inspectors whilst they carried out a building by building inspection of the whole base. The inspection commenced with the most important and potentially highest risk buildings such as food preparation areas, and medical and sports facilities. At the end of this period both parties were satisfied that the works were being undertaken to the highest standards and the inspection of the rest of the base continued.
