Sewer　pipes　health　and　failure　consequences　evaluation　are　vital　to　ensure　the　safety　of　urban　sewer　networks.　Sewer　pipes　with　low　health　and　severe　failure　consequences　should　be　the　primary　focus　of　daily　maintenance　and　management　for　drainage　authorities.　Conversely,　sewer　pipes　with　high　health　and　low　failure　consequences　are　temporarily　not　a　primary　concern,　in　order　to　reduce　resource　wastage　within　the　constraints　of　limited　economic　and　time　resources.　Thus,　the　scientific　analysis　of　their　relationships　is　deemed　essential.　This　paper　applies　supply-demand　balance　theory　to　analyze　the　relationship.　On　the　supply　side,　a　health　Fuzzy　Comprehensive　Evaluation　model　(HFCE)　is　proposed　with　weighted　hierarchies　established.　On　the　demand　side,　a　failure　consequences　FCE　model　(FFCE)　is　established.　Each　sewer　pipe＇s　supply-demand　balance　score　is　analyzed　using　matrix　multiplication,　highlighting　two　types　of　imbalanced　pipes　and　sub-districts.　Taking　the　Liangshui　River　Basin　in　Beijing　as　an　example,　the　results　show　that　the　health　evaluation　can　identify　the　spatial　distribution　of　the　health　of　sewer　pipes,　with　low　health　levels　V　and　IV　accounting　for　10.23　%　and　4.43　%,　respectively.　The　failure　consequences　evaluation　can　evaluate　the　spatial　distribution　of　the　severity　of　sewer　pipe　failure　consequences,　with　high　failure　consequences　levels　V　and　IV　respectively　accounting　for　10.97　%　and　16.77　%.　The　supply-demand　balance　analysis　identifies　the　proportion　of　the　first　and　second　types　of　imbalanced　pipes,　respectively　14.24　%　and　6.80　%.　This　method,　by　analyzing　the　relationship　of　health　and　failure　consequences,　provides　a　decision-making　basis　for　drainage　authorities　to　prioritize　sewer　pipe　operation　management,　repair,　and　maintenance.　©　2024　Elsevier　Ltd
