Service Disruption Notice – July 15, 2026
Beginning July 15, 2026, Caltrans repairs to the retaining wall in Blackie’s Pasture, along the Old Rail Trail near the Richardson Bay Sanitary District facilities, disrupted our gas and telephone lines.
At this time, we do not have an estimated date or time for restoration of service.
If you need to contact us, the fastest and most reliable method is by email at rbsdtg@aol.com.
You may also call the District office at (415) 388-1345 and leave a voicemail message. We will be monitoring and returning voicemail messages continuously throughout the day.
Thank you for your patience and understanding while these repairs are underway.
