In late 2014 the Department of Energy and Water Supply (DEWS) embarked on a program of Regional Water Supply Security Assessments (RWSSAs) to examine and update awareness of water security across regional Queensland’s significant urban centres.
The RWSSA program is a partnership between the Queensland Government, the Local Government Association of Queensland, and individual councils and their respective water supply providers across Queensland. The RWSSAs critically examine data sets available to councils and the State, and then develop and apply hydrological and other statistical assessments in order for program partners to reach a shared understanding of the capability of the bulk water supply system to meet a council’s existing and projected future water demands.
RWSSAs do not seek to provide or advocate water supply security solutions to councils; rather they contribute a solid foundation on which councils can base their own water security planning responses. Taking the approach that councils best understand local needs but can also benefit from the expertise, hydrological modelling and other information resources offered by DEWS, the partnership approach adopted in the RWSSAs built shared knowledge, trust, and strengthened cross-agency relationships.
Ian White from DEWS’ Water Supply Planning team will be give a presentation on the RWSSA program for the April 5 AWA Technical Event. The presentation will elaborate on the methodology adopted in developing RWSSAs, with emphasis on the information exchanged between the partners, and how this contributes to the decisions in the hydrological modelling subsequently undertaken in order to forecast water security for regional centres.
