The standard is applicable to external water supply networks, regardless of the form of ownership, including the water network from the water treatment plant or borehole pump to the external wall of the buildings. The standard is the basis for the design of the water network, the measurement and pumping of water pipelines, and the selection of other auxiliary equipment and the construction of a new water network as well as the expansion and reconstruction of the existing water network. The standard specifies the functional requirements for the external water supply network in relation to planning, design, construction, operation, maintenance and operation, and compliance with operational requirements.
