BACKGROUND
UNI:D
The 1-rnilhon-gallon waterstandpipe and 16,000-gallon hydropneumatic tank located at Stone Oak
Booster Pump Statim provide pressure maintenance for the Stone Oak subdivision and a portion of the
Georgetown distribution system.The pump statism adds pressure head to flows frorn the"1031 Pressure
Plane" to the „1071 Pressure Plane";thus, the pressure Dread added is approximately 40 feet(i.e., 17.3
PSI). In 2021, the City of Round Rock (OWNER) used Ardurra's services to evaluate the feasibility of
demolishing the existing standpipe and hydropneumatic tank and modifying the existing pump station by
adding variable frequency drives(VFDs)to create an in-line booster pump station.Ardurra provided a lust
of feasible alternatives for these modifications,and estimated opinion of probable construction casts for
these alternatives.These rmod°rfkations were deemed feasible avid economically beneficial for the OWNER
during this feasibility study.After meeting internally, the OWNER decided in December 2021,that they
would like to move forward with these modifications and requested Ardurra's services to do so.
The Stone Oak pump station complex comprises: a 1-rmillion-gallon (MG) standpipe; a 16,000-gallon
hydropneumatic tank with air compressor system;16-inch suction piping from the standpipe to the pump
skid and 12-inch discharge water distribution piping; two flow control valves; a local control panels a
disconnect switch;a panel board:and a skid-amounted pump station with three SCG horsepower(hp)end
suction type centrifugal booster pumps with 65 full load amp(FLA) rated motors. The existing skid also
has space for a fourth pump of equal size to each of the three existing pumps.Discharge flow,discharge
pressure,and suction pressure measurements are relayed from the sensors to the control panel. Data is
transmitted by radio from the site tower.The OWNER is In the process of converting this system to cellular
communications.
GENERAL DESCRIPTION OF THE WORK
Scope of services comprises refinement of recommendations from the feasibility study in the form of a
Basis of Design technical memorandum, coordination with TCEQ and the OWNER's water modeling
consultant to submit and obtain approval of the exception requests for the in-line boaster station(without
ground storage)and direct pressure distribution system(without elevated or hydra tank storage),detailed
design of the direct pressure in-line booster pump station system(including a 6-inch waterline to loop the
20-inch suction line), bid phase services, construction phase, start-up, and warranty phase engineering
services to deliver a complete and functional project to the OWNER.

2. The Basis of Design and TCEQ Exception Request efforts will be performed prior to initiating
detailed design so that approval isobtained from TCEQ before significant design efforts are
initiated.
3. The City's water modeling consultant will be coordinated with for the TCEQ Exception Request
effort and will provide the required modeling scenarios and results from a calibrated model to
satisfy the TCE 's requests concerning the suction and discharge sides of the Stone Oak Booster
Pump Station and the 1,031 ft and 1,071 ft pressure zones.Work by the City's modeling
consultant must be done within the proposed schedule to avoid delays and cost impacts.The
requested information must be provided by the City's water modeling consultant within two
weeks of the request for information by the Engineer.
PROJECTS
The project consists of replacing the three existing pumps by three new high flow pumps with VFDs, one
new low flow pump also with a VFD,and adding a generator.The hydropneumatic tank will be removed,
