Title: Consider executing Supplemental Contract No. 1 with BGE, Inc. for the 1 Million
Gallon Reuse Ground Storage Tank Project.
Type: City Manager Item

Agenda Date: 2/24/2023

Text of Legislative File CM-2023-036
The City of Round Rock operates a reuse water treatment facility at the East Brushy Creek Regional
Wastewater Treatment Plant. In 2011, the City of Round Rock constructed the first one million gallon
reuse water ground storage tank as part of the construction of the overall reuse water treatment facility.
The City has seen a large growth in demand for reuse water over the past few years. This demand
currently strains the existing reuse water system at peak flow rates. In order to meet the needs of the
reuse water system, Round Rock is proposing to increase the treated storage capacity of the reuse water
system with an additional two million gallon ground storage tank. This project will increase the amount of
reuse water storage to a total of three million gallons of storage at the facility.
Additional storage in the reuse water system allows the system to handle higher peak flow rates, and to
operate the system at a more steady-state. The current contract with 8GE for this project is $215,306
and it included engineering design and bid phases services for a one million gallon tank. During the
design phase, the City decided to increase the second tank size to accommodate future growth and delay
any future storage needs.
This Supplemental No. 1 will increase the contract by $48,918 for a revised total contract with BGE of
$264,224.
