Crabtree Creek PS Screw Repair

Owner / GC

City of Raleigh - Public Utilities



Completed date

February 2017

Project Type

Pump Station

While results are always important, safety is paramount and that was certainly the case on this repair for the City of Raleigh. CCI was awarded the contract to replace missing and/or damaged flights & shrouds on several large screw pumps at the City’s Crabtree Creek Lift Station. Confined space, ventilation and access / egress were all issues that had to be addressed and constantly monitored to ensure worker safety. With the station on full sewer bypass, repairs were able to be made on four of the five 70 foot long screws in just 7 days. Pump station capacity was increased from 28MGD to 33MGD after work was complete.
