Water System Management that delivers the most reliable results for
the least expense. A good large meterprogram will focus on the future and avoid tradition, as a general rule. Operators will, at times, become satis fied with their present program, not re alizing the extent of system losses as no body is looking for them. A good meter program is one that is flexible and implements a continued sys tem of checks and balances to monitor
program effectiveness. Some things to watch for as indicators that the existing program may not be as effective as pre ferred, or headed for trouble, are: (i) high unaccountable water percentage; (ii) excessive meter parts ordering;(iii) long lead time for parts delivery; (iv) consistent number of reported "dead"
registers/meters;(v)unexpected drop in demand at customer settings;(vi)change in customer base.
Certainly there are numerous other indicators but these are some of the pri mary symptoms of water revenue loss. The process of starting a large meter program involves determining the ex tent of current large meter inaccuracy, looking at the personnel complement
and deciding on a course of action. This may require the use of outside person nel to get everything in line, but program benefits will far out-weigh the trouble in getting there. Schlumberger Industries' consulting business. Revenue Manage ment Service(RMS),assists municipali ties looking for ways to increase effi ciency. This service helps municipali ties increase revenue based on meter re
placement, sizing, application, and maintenance, with guaranteed results. Over the past decade, a wealth of in formation has been uncovered about me
ter inaccuracies through the testing, in stallation and repair of thousands of large water meters of all types and manufacturers. This information has re
cently been integrated into an exclusive database. This data is completely pro prietary, with no other company or or ganization having access to the informa tion. Using the database, Schlumberger has developed a statistical linear regres sion program to plot the accuracy trends over time, using variables such as vol ume used,age, water quality, geographic trends, manufacturer, and type of me ter. This regression program allows for
an accurate prediction of the potential revenue gain in a large meter popula tion by merely looking at the statistical data information for the population. By providing RMS with basic infor mation on the meter population, such as manufacturer, model, type and size, water utility managers can use this pro gram to identify the highest potential revenue gain meters in the system, with out the expense of analyzing the entire system. Once the highest potential rev enue gain meters are identified, a com puterized meter test and flow analysis study are performed. This pinpoints the exact revenue amount lost each year through each large meter under investi gation. The water utility manager can then analyze the results which detail the exact payback for replacing the selected group of large meters. RMS then offers the water utility an opportunity to in crease revenue without investment
through various financing options which include leasing programs or installment payments, based on a portion of the in creased revenue found at the site.
