Capital Improvement Project

Seismic Upgrades and Improvements Phase 5 - R9A, R16 and R17 AND VFD and Fire Pump Additions at S16 & S17

Estimated Construction Schedule: Slated to begin September, 2023 and is anticipated to be completed November, 2025.
Construction Contract Amount: Pending
Project ID #: 2212
Description: Reservoirs 9A, 16 & 17 have numerous structural deficiencies including ringwall foundation instability, inadequate foundation reinforcing steel, insufficient anchorage embedment, excessive shell stresses in several shell courses and weak interior center support columns. While the operating water levels in each of the reservoirs should be reduced until the deficiencies are addressed, this is not currently being considered as fire protection capabilities for the areas served by the tanks would be compromised. Improvements to S16 and S17 will be made to improve firefighting capabilities and improve system redundancy.
