Upcoming Nighttime Work next Thursday evening through Friday morning

Date:     October 6, 2022
To:          Neighbors of the SD5 Main Plant
From:    Dan La Torre – Maintenance & Wastewater Collection System Superintendent
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 11pm -5am), on an (now) semi-annual basis as preventative maintenance.
This semi-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.
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 semi-annual (twice/year) activity, which ensures the safe and continued efficient operations of the SD5 Main Plant.
The cleaning activity will begin on Thursday, October 6, 2022, starting at 11 p.m., continuing through 6 a.m. on Friday, October 7, 2022.
Please contact Dan La Torre, Superintendent (415.435.1501, at ext. 107), with any questions.
We greatly appreciate your understanding while we conduct this required, preventative maintenance at Sanitary District No. 5’s Main Plant.
