The Way It Was:
City’s New Post-Earthquake
Sewer System was Top of the Line
After the devastation of the 1906 earthquake, the race was on to provide
San Franciscans with a sound, world-class sewer system. Construction
started in 1909 under the leadership of master engineer Carl Ewald
Grunsky. Ten years later, roughly 110 miles of new steel-reinforced,
concrete sewer lines were in place throughout the City. Grunsky drew on
the highest technology of the time, and his then state-of-the-art system is
the backbone of our present 1000-mile network. It’s still called the
“Grunsky System,” with most of those early lines in use today.
