Residents will begin receiving postcards in the mail, marked with the Town of Lexington's seal, requesting that they schedule an appointment. The scheduling process is made easy through both phone and online options. The actual process of replacing or retrofitting the meter will take approximately 45 minutes.
The installation work will be performed by a private contractor, Thielsch Engineering, whose installers are well trained in the replacement of water meters.
The installer will need to enter some residents' homes. It all depends on the age of the existing meter and the location of the existing endpoint/reading device. If the meter is 10 years or older, the technician will need to enter the house for a full meter replacement. If the meter was installed 9 years ago or sooner then the installer will need to enter the building if the endpoint/reading device is located inside the building.

Town Meeting appropriated the funds for this project. Water customers will not be charged for the replacement or retrofit of their existing meter(s).
Automatic Meter Reading (AMR) systems allow a community to automatically retrieve meter readings without having to enter the customer's home or facility or access their property.
The two general categories of AMR systems widely used today are mobile and fixed-network. The term Advanced Metering Infrastructure (AMI) is used to describe fixed-network AMR systems enabled with functionalities beyond meter reading for billing, such as the acquisition of interval reads and event flags, such as leak and tamper identification.
We will be installing an AMI system, which provides the following benefits:
There are a total of 14,451 active water meters exist in the Town's system. The largest portion of the DPW's metering infrastructure was installed between 1998 and 2002. As with any mechanical device, water meters are subject to wear and tear, and over time begin to lose their accuracy.
Instead of budgeting to test small meters, utilities typically budget to replace meters when they reach a specified age. The Department of Environmental Protection's (DEP) Guidelines and Policies for Public Water Systems states that the normal life expectancy of water meters ranges from 7 to 15 years. Approximately 45% of the Town's small water meters have been in service 15-years or longer.
The project involves replacing domestic and irrigation meters in service prior to 2010. These meters will be replaced with solid state meters, which do not depreciate in accuracy over time and therefore will provide great value in a replacement program.
Meters put in service since 2010 that have remaining useful life will be retrofitted with a new reading device.
