NCC Volume Three outlines the technical requirements for the design and construction of plumbing and drainage systems in both new and existing buildings. These requirements apply to all classes of buildings, regardless of the plumbing work being carried out. Additionally, Volume Three also applies to sites where water services are constructed separately from buildings.

Volume 3 covers both Domestic & Commercial installations.

Each volume contains—
•  Governing Requirements; and
•  Performance Requirements; and
    compliance options to meet the NCC requirements; and
•  State and Territory variations and additions.
