BACKGROUND
The 1-mnilhon-gallon water stamdpniipe and 'i.6"000- alllrum hydreopuneuurmatic tank located at Stone Oak
Booster Pump Station provide pressure maintenance for the Stone Oak subdivision and a portion n of the
Georgetown distrilbuution system,The pump station adds pressure(head to flows from the"1031 Pressure
Plane" to the 1.071 Pressure Plaine"; thus, the pressure head added is apuproArunatoely 40 feet (Le., 17.3
PSl). Orn 2021" the City of IRouurnd Rock (OWNER) used Arduurra"s services to evaluate the ffeasilbility of
demolishing the existing standpnipe and hydropneumatic tank and modifying;the existing pump station by
adding variable frequency drives(VFDs)to create an'in-fame Ibruoster Ipuurnlp station.Ardurra provided a list
of feasible alternatives for these modifications,and estimated opinion of probable construction assts for
these alternatives. These modifications were deemmed feasible and economically beneficial fferthe OWNER
durhng tlMs feasibillity study,after meeting internally, the OWNER decided im December 2021,-that they
would like to move forward with these modifications and requested Arduurra"s services to din so.
The Stone Oak pump station complex comprises: a I-million-pgalion (MG) standpipe; a 16,000-gaHon
lnydropneuurrnatic tank with aur compressor system; 16-inch suction pip i n frw n the standpipe to the pump
skid and 12-unch discharge water distribution pnilpirng; two flower control valves; a local control panel; a
disconnect switch;a paunel (board;and a slaiid-mcouuroted Ipuuranp station with three 50 horsepower(hp)end
suction type centrifugal (booster pumps with 65 full Nomad amp(FLA) rated motors.`rhe existing skid also
has space for a fourth puurrnpu of equal.size to each of the three existing pumps. Discharge floaw,discharge
pressure,and suction pressure measurements are relayed from the sensors to the control parcel,Data is
transmitted by radian from the site tower.The OWNER is in the process of converting this system to cellular
co immmwuunications..
GENERAL DESCRIPTlOIN OF THE WORK
Scrape of services comprises refinemnent of recommendations ffrom the feasibility study in the forma of a
