Construction at the Barton Street Pump Station, next to the Fauntleroy Ferry dock will enter the next phase on Monday, April 22 as pile driving begins.

The pump station is an underground facility that pumps wastewater to the Murray Avenue Pump Station which then pump flows to the county's regional treatment plant at West Point in Seattle.

The work will continue through Thursday, Apr. 25.

Drivers and passengers should use caution when transiting through the area.

The scope of the work at the station includes:

• Replace outdated electrical equipment, pumps, and associated equipment. The new pumps will increase capacity from 22 million gallons per day (mgd) to 33 mgd
• Upgrade heating, ventilation and air conditioning
• Construct a new underground vault to house a new backup generator system and a new odor control system
• Construct a new underground valve room and install new valves for the two 24-inch force mains that were installed as part of a 2006 emergency repair project
