It also deliveredsignifcant improvements in the health oour rivers.Now, the 2010 Metropolitan Water Plan  sets out how water agencies will workin partnership with the communityto provide a secure water supply orthe uture.It is a responsible plan that maintainsa balance between delivering watersecurity or greater Sydney whileprotecting our precious river systems.With this plan we are now able toprovide water security until at least 2025.The 2010 plan builds on the successulcore elements o earlier plans:ã continuing to source most o Sydney’sdrinking water rom our dams;ã investing in recycling to reduce thedemand or drinking water;ã supplying up to 15 per cent oSydney’s current water needs throughdesalination; andã reducing the water needs ohouseholds, businesses, governmentand arms, with innovative waterefciency programs.The progress o the 2010 plan will bereported annually, and the plan will bereviewed again in our years.There are ew more important issuesor NSW amilies and communities thanwater supply and security.That is why I am pleased to make thisplan available to explain how we aremanaging these issues, or both today’scommunities and those yet to come. Kristina Keneally MPPremier of NSW Foreword rom the Premier  2 2010MetropolitanWaterPlan Good planning or Sydney’s watersupply is essential. The 2004 and 2006Metropolitan Water Plan s have steeredus away rom immediate crisis, but uturedroughts and climate change will test thesystem again, so we have to be vigilant.Major investments in a diverse portolioo water supply options (includingdesalination, recycling, stormwaterharvesting and drought readinessmeasures) should now ensure that, atleast until 2025, Sydney’s residents candepend on their system. How the supply-demand balance will be maintained ater2025 can only be estimated now, but theplan is adaptable and the Panel eels thatit is robust, provided diligent adaptivemanagement is applied.This 2010 Metropolitan Water Plan hasassembled a cost eective portolio ooptions and has tested them against ahypothetical drought, more than twiceas bad as any experienced since recordsbegan. Moreover, that assessmentallowed or the release o long-termenvironmental ows to maintain thehealth o the Hawkesbury-Nepean Riversystem; which is valued highly by thecommunity. Although these actors arepositive, the Independent Review Panelstresses the need to keep monitoringevolving climate change modellingresults, which may revise currentestimates o water availability rom dams.The Panel has been closely involvedin the development o this 2010 planand was able to advise on aspects othe economic assessment, communityconsultation and environmental analysis.In particular, the community engagementprocess has created a healthy, whole-o-community partnership: recycling;stormwater harvesting; environmentalows and voluntary consumption targetsall received strong support.We have embarked on the journey toprovide environmental ows, having nowdecided and implemented long-termenvironmental releases rom TallowaDam on the Shoalhaven River, and Avonand the other Upper Nepean dams andweirs (including associated works or fshpassage) in the Hawkesbury-Nepean.Planning is under way or a decisionon long-term environmental owreleases rom Warragamba Dam and thePanel stresses the importance o earlyaction there.Although the current scale o alternativesources to dams is still modest, it isincreasing and, by 2015, about a quartero Sydney’s total drinking and non-drinking water needs should be comingrom desalination and recycling. The waterefciency target, another key strategyor balancing supply and demand, ishigh and may prove challenging to meet.Minimising leakage losses will needongoing commitment too, to maintain theproportion o lost water in the region oworld’s best practice.The plan was developed with regard tomany types o costs and benefts o thevarious options considered includingthose associated with energy romrenewable sources to transport and treatwater. River water quality and nutrientshave also been particularly considered orrecycling and environmental ow optionsunder the plan.For uture plans, the Panel would liketo see an expansion in the actorsconsidered in a system-wide approachto water planning which incorporatescarbon and other greenhouse gases,materials and biodiversity. Integratedurban planning is critical; water cannotbe divorced rom other sectors, andthat need was also emphasised bythe community.The community looks to governmentsto provide leadership and to osterinnovation in sustainable management owater or uture generations. We stronglysupport this approach and look orwardto seeing the development o innovativeapproaches to meet uture challengesunder the plan.
