22 SEWER SYSTEM IMPROVEMENT PROGRAM | Grey. Green. Clean. North Point Wet Weather Facility Located near Fisherman’s Wharf, the North Point Wet Weather Facility (NPF) only operates when it’s raining, and the SEP does not have capacity to handle the combined stormwater and sewage flows. The North Point Wet Weather Facility and associated facilities are a critical part of wastewater operations, and due to aging and the harsh marine environment, require upgrades. Completed in February 2018, the North Point Facility Outfall Rehabilitation Project successfully removed sediment buildup inside and outside the outfall structures, and relined/installed corrosion protection systems on pipes and structural supports. Throughout construction crews accessed pipes via manholes in the sidewalk and from barges in the Bay off Pier 33 and 35, all while monitoring and maintaining vibration and noise levels within City’s ordinances to reduce the impact to residents and businesses. The North Shore Wet Weather Pump Station Project, anticipated to begin construction in late 2019, will replace four dry weather pumps with larger units providing redundancy during wet weather, upgrade electrical distributed control systems (DCS), address corrosion and more.
