Mare Island Sewer and Water Main Replacement Project Update

The direction drilling contractor for the project at River Park is scheduled to work 24 hours a day from Thursday, November 29 through Friday, December 21. Most of the night work will take place on the Mare Island side and will involve enlarging the bore hole. 

The contractor requires a two man crew on the Vallejo side to support the operation. Work on the Vallejo side will include an excavator to secure the boring rod and to manage additional rods that are pushed through the hole from the Mare Island side. The backup alarm on the excavator will be disabled to reduce noise, and the area will be fenced off to ensure safety. The excavator will run at low speed or idle. 

When the reamer tool gets close to the Vallejo side, the mud that leaves the hole will be pumped into a truck and transported to the Mare Island side. 

The contractor will install a sound barrier at the end of the work zone and point work lights away from public areas. The 24-hour a day direction drilling operation is critical to complete the project by the end of January 2019. 

If there are any noise complaints or questions please do not hesitate to contact Ed O’Brien, Construction Manager at 707-654-9622.
