Aqwest adheres to the Water Supply Code of Australia (WSA 03 – 2002) as the base standard for design, construction and operation of its reticulation network. The WSA 03-2002 code is augmented by the Aqwest Water Reticulation Specification. Aqwest also produces a suite of “standard drawings" to inform the materials and techniques for routine reticulation works.
