The purpose of the Standard is to prescribe the minimum requirements and responsibilities of all parties involved in dual reticulation infrastructure to ensure the safety and reliability of the water services provided to South Australian consumers.
The Standard will provide clarity on mandatory requirements related to the installation and connection of dual reticulation systems to dwellings and will enable the Office of the Technical Regulator (OTR) to standardise industry practice to prevent cross-connections.
The Standard will be applicable to all new and modified dual reticulation developments in South Australia.
Why the need for such standard?
In recent years, an increasing number of incidents and issues associated with dual reticulation supply has been observed in the State. The OTR has identified inconsistencies in industry practice between the various parties (i.e. developer, builder, plumber), thus increasing the risk of incidents occurring.
In addition, dual reticulation developments are expected to increase, thus supporting the need for a solution to prevent further potential incidents.
The Standard for Dual Reticulation Infrastructure will provide a clear practice for industry to follow, removing the risk of misidentification of services and simplifying the responsibilities of each party. The aim of the Standard for Dual Reticulation Infrastructure is to eliminate cross connection incidents in dual reticulation supply.
As part of the development of the Standard, the OTR is committed to consult with stakeholders to ensure the best outcome.
