In the District’s continued effort to protect public health and the receiving waters of the State of California, the District is 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 plant’s office, located at 2001 Paradise Drive. The grit chamber cleaning is accomplished via high-powered vactor trucks which vacuum the settled debris that has been deposited at the bottom of the chamber. If this activity in 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 our neighbors closest to the plant – those in the Pt. 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 our Neighbors, to warn you of our upcoming mandatory annual activity, which ensures the safe and continued efficient operations of the SD5 Main Plant.
The cleaning will begin on Thursday, December 28, 2017, starting at 10 p.m. continuing through 5 a.m., on Friday, December 29, 2017.
Please contact Tony Rubio, District Manager (415.435.1501, ext. 106), with any questions.
We greatly appreciate your understanding while we conduct this required, preventative maintenance at Sanitary District No. 5’s Main Plant.
