Fluid Category 5 AB Air Gap Break Tank – The installation and use of cold water storage cisterns and sectional tanks connected to the public water supply must comply with Water Supply (Water Fittings) Regulations 1999 in England and Wales and the technically identical Scottish Water Byelaws.

These are fluids that represent a serious health risk due to the concentration of pathogenic organisms or highly toxic or radioactive substances present within them. This can include animal or butchery waste, faecal matter or other human waste, or pathogens from a range of other sources. Examples of environments that require these solutions include urinals, laboratories, drain cleaning plants, industrial cisterns and bin stores.  More details of the scope for these air gap tank can be found here.
