Text of Legislative File CM-2022-158
The City owns a raw water pump station on Lake Georgetown, which supplies water to Round Rock's Water
Treatment Plant. In the past several years, invasive zebra mussels have been detected in Lake Georgetown
and on the intake structure of the raw water pump station. Zebra mussels have a long history of attaching
in massive quantities to raw water intakes and pipelines, damaging the infrastructure and restricting flow
to the facility.
This project aims to construct a sodium permanganate chemical feed system at Round Rock's Lake
Georgetown raw water pump station. The system assists with taste and odor issues, provides manganese
control, and assists zebra mussel prevention in raw water pipelines. The project consists of a chemical fill
station, a bulk chemical storage tank, a chemical building, and three chemical feed lines down to the raw
water intake.
As part of the construction, a chemical fill station was added outside the Lake Georgetown pump station
fence. After construction, it was determined that a small fence should be constructed to protect the fill
station. The Department is requesting thirty days for the fence construction and 120 days for servicing the
flow meters before the station is placed in operation. This additional work outlined in Quantity
Adjustment/Change Order(QA/CO) No. 3 will cost $5,341.49. The City awarded Associated Construction
Partners, LTD the contract in June 2020 for $1,064,900. With the addition of QA/CO No.'s 1, 2, and 3, the
new contract total is $1,137,330.96.
