The City of Round Rock's Communications and Water Plant Control System Improvements project involves
updating communication infrastructure in Round Rock's water treatment plant (WTP), reuse water
distribution system, water distribution system and wastewater collection system.
Due to the rapid advancement of technology, the electronic control system infrastructure associated with
Round Rock's WTP has either become outdated, reached its design life, or is no longer supported by the
manufacturer. This project will reorganize, consolidate controls, upgrade the hardware, and network
components to current industry standards. Updating the WTP's hardware also provides the opportunity to
switch the WTP's operating platform to match the operating platform currently being installed at the
Brushy Creek East Regional Wastewater Treatment Plant. Updating the hardware and using the same
operating platform and programming architecture across the entire water and wastewater system provides
for operational efficiency and a more maintainable system.
This project will update the current field communication network to a modern cellular network. Doing this
will allow for increased reliability in the system, the ability to transmit more information and increased
ease in adding additional monitoring to the system.

Agenda Item Summary Continued (CM-2021-292)
Change Order No. 2 will deduct stainless steel doors that were required per the contract and spare parts
that were provided by the City of Round Rock. This change order also accounts for additional inputs for the
Solids and Chlorine Buildings at the water treatment plant. The inputs work was not contemplated in the
original contract and will require new discrete output cards, interposing relays, terminal blocks, and other
miscellaneous wires. During the installation of the new wireless monitoring system, it was determined
that the walls were too thick to allow the tablets to function properly. To improve the tablets functionality,
WIN expansion devices were added. The cost for this additional WIFI coverage is also contemplated in
Change Order No. 2.
On October 8, 2020, the City of Round Rock entered an agreement with Control Panels USA Inc. for
$2,495,359.On May 13, 2021, additional site monitoring systems were approved as Change Order No. 1
which added an additional $89,925 to the contract. With the addition of Change Order No. 2 for $29,956
the new contract total will be $2,615,240.
