Upcoming Night Work on Thursday, November 4th, 2021: 10PM - 5AM

Friends & Neighbors of SD5: 

In the District's continued effort to protect public health and the receiving waters of the State of California, the District has been required to perform a cleaning activity during the low-flow hours of the night and into the early morning (between 10 p.m. – 5 a.m.), on an annual basis as preventative maintenance.

This annual preventative maintenance activity includes the cleaning of the grit chamber located at the front of the treatment plants office located at 2001 Paradise Drive. The grit chamber cleaning is accomplished via high-powered vactor trucks that operate to vacuum out all of the settled debris that has been deposited at the bottom of the chamber. If this activity is not performed on schedule, the District runs the risk of damaging plant equipment by allowing this debris to flow in to the plant uncontrolled.

FOR BELEVEDERE: As part of the District’s continued effort to protect critical infrastructure, the cleaning and vacuuming by the use of vactor trucks must also take place occasionally at certain pump stations within the District. The Cove Road pump station in Belvedere is the largest station in the city and conveys 100% of all sewage from Belvedere to the treatment plant at 2001 Paradise Drive in Tiburon. The cleaning of the grit chamber at the treatment plant provides staff with an opportunity to service the Cove Road station and perform this cleaning task.  

The District understands that our neighbors closest to the pump station may be affected by the noise and light emitted from the cleaning project. The District is providing this courtesy notice to you, our Neighbors, to warn of our upcoming project. We thank you for your understanding and patience as we perform this critical maintenance to ensure the longevity and reliability of the sewage infrastructure.

FOR TIBURON: This annual preventative maintenance activity includes the cleaning of the grit chamber located at the front of the treatment plants office located at 2001Paradise Drive. The grit chamber cleaning is accomplished via high-powered vactor trucks that operate to vacuum out all of the settled debris that has been deposited at the bottom of the chamber. If this activity is not performed on schedule, the District runs the risk of damaging plant equipment by allowing this debris to flow in to the plant uncontrolled.

The District understands that our neighbors closest to the plant - those in the Point Tiburon Bay Side Association, those located directly above us on Centro and Diviso streets, and those on Paradise Drive (on the bay-side of the plant), may be affected by the noise and light emitted from the cleaning project. The District is providing this courtesy notice to you, our Neighbors, to warn of our upcoming mandatory annual (only once/year) activity, which ensures the safe and continued efficient operations of the SDS Main Plant.

The cleaning activity will begin on Thursday, November 4, 2021, starting at 10 p.m., continuing through 5 a.m. on Friday, November 5, 2021.

Please contact Dan LaTorre, Maintenance & Collection Superintendent ((415) 286-1477) with any questions.

We greatly appreciate your understanding while we conduct this required, preventative maintenance at Sanitary District No. 5's Main Plant and Belvedere's Pump Station #1.

Sincerely,

WE ARE NOW OPEN!
