The　key　of　sustainable　development　of　newly　urbanized　areas　often　lies　in　tackling　with　issues,　such　as　population　growth,　growing　resources　constraints,　coordination　between　regional　and　urban　needs,　etc.　Water,　as　one　of　the　shared　and　liquid　resources,　has　been　playing　a　more　and　more　important　role　in　sustainable　urban　planning　nowadays.　Conventional　water　resource　planning　concept　alone,　i.e.　planning　for　adequate　and　reliable　water　supply,　could　no　long　address　the　growing　urbanization　needs.　Especially　in　China,　water　resource　management　practices　are　still　under　the　guidance　following　conventional　mindset　and　compliances.　It　was　yet　brought　up　to　people＇s　attention　that　water　resource　planning　is　a　crucial　element　of　urban　planning,　not　to　mention　the　effort　that　should　be　spent　in　localized　investigating　and　exploring　the　potential　value　of　water　to　economy,　esthetics　and　social　development.　This　paper　takes　Sino-Singapore　Tianjin　Eco-city　as　a　case　to　study　its　future-ready　approach　in　managing　its　local　water　resources　under　water　scarce　urban　settings,　i.e.　recovery　of　the　polluted　water　environments,　integrated　planning　of　catchment　and　reservoirs　for　stormwater　storage,　acquiring　new　resource　to　supplement　and　replacing　conventional　water　resource,　adopting　water　sensitive　urban　design　to　rediscover　the　added　value　of　water　resource　to　urban　development,　establishing　PPP　network　for　water　demand　management　and　water　resource　protection,　etc.　By　reviewing　Eco-city＇s　strategies　on　sustainable　in-situ　water　resources　planning,　the　existing　urban　water　resources　shortage　situation　in　some　of　China＇s　coastal　water　scarce　cities　would　be　addressed　and　suggestion　for　urban　water　resource　sustainable　planning　and　use　would　also　be　given.　©　2011　IEEE.
