In Africa, a quarter of water points are non-functional at any given time. Communities often lack the resources and technical expertise to deliver maintenance effectively, while bureaucrats lack local information. We report results from a randomized evaluation of a nationwide program designed to improve maintenance by strengthening collaboration between village water organizations and district water officials in Tanzania. The intervention enhanced the perceived quality of these relationships and induced both actors to allocate more resources toward maintenance. There is an overall increase in system functionality, but the effects are concentrated in villages that already had relatively high baseline functionality.","geographic_units":[{"name":"Tanzania","code":"TZA"}],"keywords":[{"name":"Water Supply"},{"name":"Maintenance"},{"name":"Coproduction"}],"topics":[{"id":"H11","uri":"https:\/\/www.aeaweb.org\/econlit\/jelCodes.php?view=jel","vocabulary":"Journal of Economic Literature (JEL)","name":"Structure, Scope, and Performance of Government","parent_id":"H1"},{"id":" H44","uri":"https:\/\/www.aeaweb.org\/econlit\/jelCodes.php?view=jel","vocabulary":"Journal of Economic Literature (JEL)","name":"Publicly Provided Goods: Mixed Markets","parent_id":"H4"},{"id":" Q25","uri":"https:\/\/www.aeaweb.org\/econlit\/jelCodes.php?view=jel","vocabulary":"Journal of Economic Literature (JEL)","name":"Water","parent_id":"Q2"},{"id":" Q58","uri":"https:\/\/www.aeaweb.org\/econlit\/jelCodes.php?view=jel","vocabulary":"Journal of Economic Literature (JEL)","name":"Government Policy","parent_id":"Q5"}],"output":[{"type":"Working Paper","description":"Policy Research Working Papers (PRWP)","title":"The State Of Maintenance: Can Government And Citizens Cooperate For Improved Water Access?"}],"language":[{"name":"English","code":"EN"}],"technology_requirements":"Runtime: 3 minutes","disclaimer":"The materials in the reproducibility packages are distributed as they were prepared by the staff of the International Bank for Reconstruction and Development\/The World Bank.
