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.

High quality water is more than the dream of the conservationists, more than a political slogan; high quality water, in the right quantity at the right place at the right time, is essential to health, recreation, and economic growth.

We must treat water as if it were the most precious thing in the world, the most valuable natural resource.

Water links us to our neighbor in a way more profound and complex than any other.

We need a global approach to this from all sides. We need to educate people, we need the scientists to create new technologies, we need the engineers to create the networks, we need every human being to be aware of how precious water is and save it. Everybody has to be involved in a very firm and assertive way.

The Romans realized, as have every civilized people since, that living in cities is impossible if the water supply is not reliably clean and fresh.
