These devices are used to download the meter read routes and once the meters are read, the devices are used to upload the data for billing. City utilizes three full time meter readers currently for 8 meter read cycles. There is one vacancy for a meter reader as earlier there were three meter readers. Meters are read on a bi-monthly cycle with half of the meters being read in one month cycle. Meter readers average 600-700 reads in good areas and about 80-150 in areas where pits get filled with dirt. Most cycles are completed in two days. Billing system checks the . reads for errors and missing reads, a meter read report is reviewed for abnormal or missing reads and meter readers are assigned to re -read the meters identified in the report. 3.2.2 Billing System and Other Related Software 3.2.2.1 Billing Process The meter reads uploaded from the handheld devices are provided to the billing system. The customers are billed bi-monthly based on the eight meter read cycles. Meters are read again if there is a customer complaint after billing to identify the issue. Billing system used by the City is Enquesta. Generally, utilities use customer information systems (CIS) that store the customer and account information and are used as the billing system. This document refers to the billing system as CIS and for City, Enquesta is the equivalent of CIS. The main difference between MDMS and Enquesta is that MDMS does not do billing like Enquesta but can provide the billing determinants (billing reads) to Enquesta. The second difference is that MDMS can validate, estimate, edit the smart meter reads and store these hourly reads. MDM Systems can analyze the hourly data and provides monthly or time of use billing data as required by billing systems. Enquesta cannot store large volume of hourly meter reads or create billing determinants easily from this data. 25G-126
