Burk-Kleinpeter, Inc.
(BKI) was contracted to
design and oversee the expansion of Drainage Pumping
Station No. 6 (DPS 6), one of the
world's largest pumping stations. The focus
was on hydraulic improvements to the intake
and discharge basins, evaluation of mech-
anical and electrical equipment associated
with two new 1,100-cubic feet per second
(CFS) pumps, architectural and structural
modifications to the existing structure, and
replacement of the four original 250-CFS
pumps. Prior renovations to the facility had
produced an awkward hydraulic condition in
the intake basin. Drainage waters negotiated a 90°
turn and bypassed the large horizontal
pumps, which were unable to operate at full
capacity, while the smaller pumps were being
overworked as the waters accumulated in the east
side of the basin. The use of deflector walls
proved unsuccessful. Hydraulic flow simulations in a
scale model provided a solution which
produced acceptable flow conditions at the intake
basin. Similar studies of the outfall basin
provided recommendations for improvements in
discharge flow. Resolution of the poor hydraulic
conditions enabled the pumping station to function
at its full 10,000-CFS capacity.
Construction cost was approximately $18.5 million.
