             A sufficient supply of water is a very basic necessity for most buildings to enable inhabitants to carry out everyday tasks such as cleaning, cooking and as well as manufacturing purposes. Water is in the first instance produced by condensation in the form of clouds and falls to the ground as rain, snow or hail. It either becomes surface water in the form of a river, stream or lake or absorbs through the subsoil until it finds what is called an impervious stratum or otherwise held in a water bearing subsoil. The water from a reservoir or lake is treated to remove the suspended organic and inorganic materials. This process is vital so that all pathogenic bacteria can be destroyed that can cause diseases such as typhoid and cholera.
             In the UK it is a statutory requirement of the Water acts that every building or dwelling is supplied with water fit for drinking. The way in which it is done is by the necessary water companies laying mains underground at a depth where they will be unaffected by frost and traffic movement. The layout of the system is usually a circuit with trunk mains feeding a grid of subsidiary mains for distribution to specific areas and districts.
             Connection of water supply to a low rise building
             Water supplies can be connected to a property or low rise building from the mains supply provided that the building owner or occupier has complied with the requirements of the Water Act 1989 and that the installation as a whole satisfies water by-law requirements. The low-rise buildings are connected to the water main by a service branch pipe, which is shown in figure 1 and 2, that shows a direct and in-direct water supply.
             This connection arrangement usually consists of: -
