South Macadam Avenue water main replacement

Project overview

The Water Bureau is replacing 980 feet of water main (pipe) on South Macadam Avenue from South Lane Street to South Bancroft Street. We will also install two new hydrants, one near the intersection with South Thomas Street, and one near the intersection with South Lowell Street.

The existing water main was installed in 1893 and has had three reported leaks. The new pipe will reduce breaks and leaks, and will be more resistant to earthquakes. If you live in the area, this new pipe will make your water service more reliable.

What to expect during construction

To replace a water main, we cut the road surface, dig a trench, replace the old pipe, connect the new pipe to people's water meters, fill the trench, and restore the road surface.

• Due to the project's proximity to the I-5 freeway and the 299A off-ramp, some night work will be necessary.
• Street parking may be limited. We may set up "No parking" signs.
• Your street may be closed to all but local traffic during construction hours. Crews will try to keep driveways accessible, but you may have to park on a side street sometimes during construction hours.
• Your water service may be disrupted for several hours. If we need to shut off your water, we will hang a notice on your front door at least 24 hours before the shutoff.
• Mail, garbage, and delivery services will have access.
• You may experience noise, dust, and traffic delays.

We may work at night in order to limit impacts on traffic in the area. We will update this page and notify neighbors when we have more information about our schedule.
