There are two main decisions faced by utility managers regarding meters in an undertaking: which meter to instal and when to replace it. Traditionally the criteria used to make these decisions have been arbitrary and often imposed by third parties regardless of the situation of the individual undertakings. This paper presents “Comparative billing analysis”, a methodology to analyse meter performance within the undertaking, as a means to support decision making in water meter management.
The main difference between the comparative billing analysis and previous methodologies resides in the use of the commercial billing database that most undertakings have these days. By analysing existing data with a systematic approach, it is possible to determine which kind of domestic meter is most appropriate for the utility. This method turns out to be as reliable as previous ones, but much more efficient in the use of economic and human resources.
