New Crystal Springs Bypass Tunnel: Pipeline Connection Activities and 24-Hour Work

In January and February 2011, the SFPUC and its contractor will be performing water pipeline connection activities at the North Shaft (Crystal Springs Road at Polhemus Road) and the South Shaft (Polhemus Road between Bunker Hill and Crystal Springs Road)in San Mateo.

Several workers from the SFPUC’s Water Supply & Treatment Division will be performing 24-hour pipeline de-watering and treatment work at both the North and South Shaft sites starting on or around January 4th through the 9th. Downward-facing lights will be in use at night during this time.

Workers and staff will be at the North and South Shaft sites and along Polhemus Road at various times from January 3rd through the 17th to prepare for pipeline connection activities. Tunnel ventilation equipment, including an air compressor, will be in use at the South Shaft during the day on Sunday, January 16th.

Starting on or around January 17th, 2011, the contractor will perform critical work to connect the new pipeline to our water system. These important pipeline connection activities at the South Shaft site will require crews to work up to 24 hours a day, 7 days per week for approximately 3 weeks to complete this critical work as quickly as possible. Neighbors may experience some noise from the crane and equipment.

Additional environmental training focused on minimizing noise, especially at nighttime, is being conducted for all workers on site.

We do not anticipate any interruption to your water service. This important work is necessary to connect pipelines for your water supply.
