The Crane’s Eye View

By mid-December, the Harry Tracy Water Treatment project will conclude two months of intensive work on new pipeline segments and upgrades to the treatment plant.  During this period regular operations have been suspended.  The project is over 65% complete, thanks in part to the swing shift started earlier this year to complete the new treated water reservoir. When the Plant comes back online later this month, the swing shift is expected to conclude. Extended hours and swing shifts may again be required in the future to stay on schedule or due to the demands of the work.

Work will continue throughout the Plant from 7 a.m. to 5 p.m. including most Saturdays from 9 a.m. to 5 p.m.
Steel-reinforced concrete columns are currently being constructed inside the new 11 million gallon treated water reservoir (photo above). The yellow metal forms are reused after each column has hardened. The columns will soon support a reinforced concrete roof. Waterproofing and water quality testing will follow before placing the new reservoir into service. 
Meanwhile construction of the reservoir walls is almost finished. The inner wall is more than 75% formed, and the outer wall is now complete except for a temporary opening for equipment and materials.

These new below-grade filters will increase our reliability 
to process raw water into drinking water.

What to Expect

  • Building materials are delivered via Crystal Springs Road in San Bruno. Flaggers control truck traffic at the Plant gate and pilot cars escort trucks along the road for safety.
  • Truck off-hauls occasionally begin at 7:00 a.m.
  • Noise levels are monitored to maintain compliance with local ordinances.

The contractor is working to minimize disruption to our neighbors. Please don’t hesitate to call our 24-hour phone line at (866) 973-1476, or email with questions or suggestions.
