In April of 2014, the City Council approved a construction contract with TraC-N-Trot, Inc. for the RTU
Install & Enhancement Project - Phase 2 in the amount of $101,302.
The City currently utilizes a number of Remote Terminal Units (RTUs) that are located at every
pump station, storage tank, and lift station site in the Utility system. These RTUs allow the City to
monitortank levels, pump run times, etc.
Phase 1 of this project replaced an existing obsolete Front End Processor, and provided the City
with thirty-four RTUs and radios to replace thirty-four existing RTUs and radios. This will improve the
City's software development/run time
environments to increase data capabilities by upgrading the radio system from 1200 baud to
Ethernet. Upgrading the Water Supervisory Control and Data Acquisition system will ensure a safer
and more up to date communication
system in managing our Water Distribution system and Wastewater Collection system.
Phase 2 includes the installation of the RTUs and radios, a Line of Sight investigation, and a Bird
Watt test to ensure conductivity in the wiring between the antennae and the RTUs.
During the course of testing, it became clear that there was a need for programming of the
Programmable Logic Controllers (PLC's), and the addition of the Bird Watt lest to nine other sites
based on the prior test results.
The City Utility Staff recommends the City Manager approve Quantity Adjustment/Change Order No.
1 for the amount of $5,434 which will change the contract total to $106,736.
