Water　production,　utilization　and　recycle　in　urban　system　associated　with　a　large　amount　of　energy　consumption　and　carbon　emission　that　has　increasingly　international　attention　under　sustainable　development　goals.　In　this　study,　a　comprehensive　urban　water　resources　system　management　model　is　proposed　under　water-energy-carbon　nexus　and　multiple　uncertainties.　The　water-energy-carbon　nexus　was　reflected　in　the　processes　of　water　extraction,　water　production　and　sewage　treatment,　and　two　objectives　of　maximizing　the　system　benefit　and　minimizing　carbon　emission　is　transformed　into　two　linear　programming　problem　through　the　dual-objective　interval　fractional　programming.　Considering　the　interaction　among　water　supply/demand,　pollutants　discharge　control,　energy　consumption　and　self-energy　utilization,　indirect　carbon　emission　as　the　main　constraints,　the　developed　model　is　applied　to　a　typical　water　and　energy　sources　shortage　area　of　Qingdao　city　in　north　China.　Multiple　scenarios　related　to　energy　consumption　and　carbon　emission　control　are　designed　to　search　the　relationship　among　energy　consumption,　carbon　emission　and　water　resources　allocation　schemes.　The　results　indicated　that　water　demand　as　the　main　driving　factor　of　energy　consumption　and　carbon　emission　in　urban　water　system　cannot　be　directly　limited　through　water　supply　structure　adjustment.　Through　introducing　self-energy　supply　(sludge　utilization)　and　energy　consumption　control,　water　resources　allocation　schemes　and　water　supply　structure　would　be　changed　to　improve　energy　saving　potential　with　an　obvious　decrease　trend　of　carbon　emission　intensity　from　0.7921　tCO2/MWh　to　0.5544　tCO2/MWh.　The　model　could　effectively　provide　reasonable　urban　water　system　management　strategies　under　different　water　allocation　demands　and　carbon　emission　challenges　scenarios　and　deal　with　multiple　uncertainties　in　decision-making　process.　©　2023　Elsevier　Ltd
