Substandard Supply Minutes in the Netherlands
The new performance indicator Substandard Supply Minutes (SSM) is an extension of the performance indicator Customer Minutes Lost (CML). CML measures the average interruption time due to failures. SSM measures the average time that no drinking water is supplied. Substandard water supply is defined as supplying water that does not meet the quality standards or water that is supplied in too little quantity (too little pressure or an interruption of the water supply); the standards for water quality and pressure are defined in the Dutch Drinking Water Act. SSM includes interruptions due to failures of the distribution system as well as due to planned repairs and replacements. From September 2004 to March 2005 SSM was measured in a pilot project. Of the 13 Dutch water companies 7 joined this project. In 2006, SSM has become part of the benchmark of the Dutch water companies and most water companies use SSM in their asset management processes. This paper was presented at the 8th Annual Water Distribution Systems Analysis Symposium which was held with the generous support of Awwa Research Foundation (AwwaRF).
