Assessing the failures in water distribution networks using a combination of geographic information system, EPANET 2, and descriptive statistical analysis: a case study

Nowadays, issues related to water are considered one of the most significant and vital problems in human societies. One fundamental branches crisis is distribution network-related problems. The present study attempted extract, classify verify failure data obtained from Preventive Maintenance database Birjand Water Distribution Network (WDN). WDN was meshed terms rate failures using a combination geographic information systems (GIS) EPANET 2. Then it assessed descriptive statistical analysis method. Investigations revealed that middle sections involved highest failures. Furthermore, investigations demonstrated 2011 2016 per kilometer year ranged range 0.6–1.8 which aggregation for all cells. In this regard, intensity occurrence estimated as 1.4–1.8, while 2012, 2013, 2016, 1–1.4 finally 2014 2015, estimations showed an interval 0.6–1.
