Text of Legislative File CM-2022-064
The City operates a groundwater well site located south of downtown Round Rock. This site, referred to as
the Lake Creek well site and pump station, uses chlorine gas in its treatment process. The chlorine gas is
stored and utilized inside of a chlorine building located onsite.
The Utilities and Environmental Services (U&ES) Department recently completed a risk assessment for the
water utility. This risk assessment identified the lack of an emergency chlorine scrubber system at the Lake
Creek well site as a potential risk. To mitigate this risk, our department seeks to add a chlorine scrubber
system to the existing chlorine building.
A chlorine scrubber system is activated in the event that a chlorine leak is detected inside the chlorine
building. When the system is activated, chlorine gas is pulled from the building by the scrubber unit and
neutralized. The addition of a chlorine scrubber unit will greatly increase operator safety and prevent
damage to the Lake Creek well site in the event of a chlorine leak.
The existing chlorine building is not of sufficient quality to support a chlorine scrubber unit due to the
buildings inability to be sealed in an emergency. In addition to the chlorine scrubber unit, this project
includes the construction of a new chlorine building that will facilitate the use of the scrubber. A bathroom
for the plant operators will also be added to the new chlorine building.
