Depression-era pipe now on display at Bonita Museum


Earlier this year, the Sweetwater Authority completed the replacement of its 36-inch transmission main in the Bonita Valley area. Portions of this large pipeline were nearing 100-years-old and needed to be replaced. A portion of this history is now on permanent display at the Bonita Museum.

Constructed in 1926, the original riveted steel pipeline played a key role in delivering safe, reliable water to Authority customers throughout the South Bay, with drinking water from the Authority’s treatment plant in Spring Valley traveled through the pipe, through the Bonita Valley including Bonita, western and central Chula Vista and National City.

“Replacing the 36-inch transmission main was a major infrastructure improvement project for the Authority last year, and we’re proud to be able to preserve a piece of our community’s history now that the project is complete,” said Authority Board Chair Hector Martinez in a press release. “The water we’ve delivered to our customers over the last century has passed through this pipe, and we are glad the Bonita Museum & Cultural Center is able to share this piece of history with the community.”
