A San José-Santa Clara Regional Wastewater Facility (Facility) project to conduct storm drainage and sanitary sewer infrastructure improvements within the 196-gross acre Main Operational Area of the Facility, including, but not limited to pipeline unclogging and/or replacement, storm drain inlet improvements, and Facility tunnel entrance waterproofing. Additional improvements both within and outside of the Main Operational Area to stormwater pump stations and associated infrastructure including, but not be limited to replacement and upsizing of stormwater pumps, replacement of three stormwater pump stations, inlet ditch upgrades, new lighting, restoration of walking surfaces and replacement of electrical cable to pump stations where needed. Approximately 2,800 feet of stormwater pipes would be replaced and approximately 5,500 feet of stormwater pipelines would be inspected, flushed, and cleaned. Approximately 1,000 feet of sanitary sewer pipelines would be replaced, while approximately 1,700 feet of sewer pipelines would be inspected, flushed, and cleaned. Approximately 6,000 sq. ft. of ground disturbance will result from storm drain and sanitary sewer pipeline replacement; less than 0.14-acres of ground will be disturbed.
