If you travel along Carlsbad Boulevard around Cannon Road, please be aware that a project to replace aging water and sewer pipelines will cause some temporary lane closures and traffic delays starting this week and continuing for about a year (minus the busy summer months, when we will stop major work in the road).
The city has more than 6,500 feet of water and sewer pipes in that area that are reaching their end of life and need to be replaced or repaired.
If you’re in the area, here’s a quick snapshot of what you can expect during construction:
- Construction hours are weekdays, between 7 a.m. and 4 p.m.
- Parking will be more limited than usual. Look for temporary no parking signs to avoid getting a ticket
- Bike lanes near work areas will be closed during construction. Please share the road and give yourself extra time. If you’re planning to bike in the area, consider an alternate route.

Remember to check our construction map to see where major construction is planned next week throughout the city.
About our water system
October marks the 110th anniversary of the first water system in Carlsbad. How can that be, when the city itself is only a sprightly 72 years old? Let me explain:
- In 1914, the South Coast Land Company established the first drinking water system in Carlsbad, bringing water into the area through wells dug along the San Luis Rey River, traveling in six-inch redwood pipes over the Buena Vista Lagoon, to what we know today as downtown Carlsbad.
- In 1927, this system became known as the Carlsbad Mutual Water Company, which went on to build the Calavera Dam in 1941.
- Over the years a few more water companies were created before they eventually merged to create the Carlsbad Municipal Water District in 1954.
- Today, the Carlsbad Municipal Water District is still the water provider for about 85% of Carlsbad. The southern part of the city is served by the Olivenhain Municipal Water District and the southeastern area is served by Vallecitos Water District. (Find your water district.)
- Our water district is considered a “subsidiary district” of the City of Carlsbad. The City Council also serves as the water district’s board of directors.
Getting back to the pipeline project around Carlsbad Boulevard and Cannon Road, when the Carlsbad Municipal Water District was formed, the water system in Terramar was one of the first to be upgraded with new water mains installed between 1958 and 1971 (hence the need for an upgrade now!).
P.S. If you’ve heard about the Carlsbad water with special healing powers, that discovery precedes the first water system and will have to be a story for another day. Or, if you can’t wait, the Carlsbad Historical Society has a wealth of information about local history on its website, and our library’s history collection is also full of interesting stories from our past.
