Nationally Agreed Failure Data and Analysis Methodology for Water Mains : Volume I - Overview and Findings
This two part report provides an account of the development of a national failure database for water mains which includes a suggested common protocol for data collection. The first part of the report sets out the principles on which the protocol was written and a description of the work involved in forming the national database. The second part is the detailed protocol. 21 Water companies collaborated on the project and 15 provided both failure and mains length data which were processed to form the first National Failure Database. Forming the database highlighted widespread reporting differences that make comparisons difficult and the protocol proposes "best practice" solutions to these differences. The protocol offers a practical way forward for companies when opportunities allow for improvements in existing systems and practices. Sold as a 2 Volume set with 03/RG/05/8
