Public Works

Last Week Stunk

Last week, I toured the City of San Jose’s sanitary sewer system along with Public Works staff. For those of you who may not be aware, sewers in San Jose stretch out for 2,200 miles and range anywhere from 100 years old to brand new. The “sewer freeway” is at Zanker Road, where four large- diameter lines converge towards Alviso. They run side by side in different sizes and during the dry season we turn two of them off since the flow is slower without rainfall. This gives a rest to the other lines so they can be inspected and also helps move solid materials (grit) through the pipes.
