Chinatown and SOMA Large Diameter Sewer Improvements

candidate project Design abaae338-46a8-4d1c-93a7-d7917c015eb1

The Chinatown and SOMA Large Diameter Sewer Improvements is an active sanitary sewer project owned by San Francisco Public Works (in coordination with the SFPUC under Contract WW-812). It involves rehabilitating brick and concrete sewers ranging from about 2.5 feet by 3.75 feet up to 10 feet in diameter along several downtown and South of Market corridors, including 5th Street, 1st Street, and The Embarcadero. The project is currently in design, with construction scheduled to run from mid-2027 to mid-2028. No cost figures have been published.AI-generated

summary The Chinatown and SOMA Large Diameter Sewer Improvements is an active sanitary sewer project owned by San Francisco Public Works (in coordination with the SFPUC under Contract WW-812). It involves rehabilitating brick and concrete sewers ranging from about 2.5 feet by 3.75 feet up to 10 feet in diameter along several downtown and South of Market corridors, including 5th Street, 1st Street, and The Embarcadero. The project is currently in design, with construction scheduled to run from mid-2027 to mid-2028. No cost figures have been published. generated 2026-07-18 live
