The City owns and operates about 130 lift stations, which are an essential part of the City’s wastewater collection system. Annually, the City conducts lift station rehabilitations based on routine inspections and assessments of the wastewater collection system. In FY2017, the following four (4) lift stations were recommended for rehabilitation:

• Vista Lakes (No. 106)
• Ferry Landing (No. 125)
• Dulles #1 (No. 136)
• Dulles #2 (No. 137)

All four (4) lift stations require major rehabilitation in order to avoid continued deterioration of the stations that may result in failure and higher repair costs in the future  They will also be brought into compliance with electrical codes for efficient operation and safety of operational staff.  These lift station components are nearing the end of their service life and require rehabilitation. 

The rehabilitation project scope of work includes the following tasks:

• Valve vault modifications / Pump installation / Riser and header piping installation
• Electrical Improvements /SCADA programming
• Wet well recoating / By-pass pumping / Start-Up Testing / Miscellaneous improvements
