Selecting & Prioritizing Pipeline Replacements Using Pipeline Risk Model in GIS
Authors: Elena Dudek
East Bay Municipal Utility District (EBMUD) is constantly replacing aging pipelines. The greatest challenge for the Pipeline Replacement Program is ensuring EBMUD selects projects that significantly reduce risk. EBMUD uses ArcGIS Desktop, with an add-on asset management software, Innovyze’s InfoMaster,to run a Pipeline Risk Model that ranks 4,200 miles of pipeline by risk score using various geoprocesses and calculations. Pipeline replacements are selected and prioritized based on model results.
