The Occoquan River Crossing project is a collaborative effort between Fairfax Water, Prince William County Service Authority (PWCSA), and Virginia American Water (V-AW) to increase drinking water transmission capacity and enhance system reliability for existing and future PWCSA and V-AW customers in eastern Prince William County.
This project will replace aging potable water transmission main crossings of the Occoquan River with dual 42-inch mains inside a 400-foot long tunnel to cross beneath the river near the Town of Occoquan. The construction work will occur on Fairfax Water property and within existing Fairfax Water easements and will last for approximately twenty months.
Construction Activities for February and March 2024:
- Perform grouting operations inside horizontal tunnel and North/South vertical shafts
- Installation of water main in North vertical shaft and outside of Raw Water Pump Station
- Installation of water main outside of South vertical shafts
- Excavation and prep for water main connections to existing system
