Colonel Ward High Lift Energy Performance Contract
Danforth implemented energy saving measures including: installation of two new VFD-controlled 20 MGD, 750 HP vertical dry-pit pumps to supplement three existing 50 MGD pumps. This included all associated suction and discharge piping, valves and fittings ranging in size from 16” up to 48” as well as the installation of electro-hydraulic actuators on the three existing 30” cone valves.
Also completed was installation of electric actuators on three existing 42” butterfly valves and excavation of the pump pit, which included an extensive geo-civil engineering plan requiring the use of drilling & grouting, tie-back anchors and dewatering. A 48” Suction Header was built through an excavated tunnel to tie in the new pumps to the existing filtered water conduit and upgrades to the electrical motor control center were completed to accommodate the new pumps.
This project also involved upgrades to the two 25 ton overhead bridge cranes and finally, the installation of a HVAC system for the High Service Control Room.
Danforth coordinated and successfully completed all of this highly detailed work using all of our resources. The result was a more efficient pumping station and a system that reduces energy consumption while increasing capacity.
