Contract Opportunity
The Cleanwater Program at the Sunnyvale Water Pollution Control Plant (WPCP) is currently underway with several concurrent projects at and adjacent to the WPCP, including the following:
Project
Expected Bid
Expected Substantial Completion
Project 1.1 – Headworks and Primary Treatment Facility
NTP Issued June 2016
2021 Q2
Project 8.1 - Caribbean Drive Parking and Trail Access Enhancements
2019 Q1
2019 Q4
Project 8.3 - Administration and Lab Building
2020 Q2
2022 Q1
Projects 2.2 – Secondary Treatment and Thickening and Dewatering
2021 Q1
2023 Q4
Work also expected adjacent to the Sunnyvale WPCP includes the construction of the Santa Clara Valley Water District East-West Channel Project (expected bid 2019Q2 / expected substantial completion 2021Q2).
The City is near completion of the initial phase of Project 2.1 Existing Plant Rehabilitation, which involved a detailed condition assessment of select assets at the WPCP, including:
Oxidation Pond System
Chlorination System
Fixed Growth Reactor – Air Flotation Tank Systems
Tertiary Dual Media Filters
Chlorine Contact Area
Influent Sewer Piping
Rehabilitation of these WPCP assets is needed now so that these facilities remain functional until Stage 2 of the secondary treatment facilities are complete (i.e., through 2035). The City wishes to solicit proposals from design consultants for the rehabilitation of the assets identified in the Facility Condition Assessment Report. In addition to the rehabilitation of assets identified in the report, this project will include the rehabilitation of the primary effluent pipeline (which conveys primary effluent from the WPCP to the oxidation ponds) and Phase 2 of the perimeter wall (Phase 1 is currently under construction as part of Project 1.1 - Headworks and Primary Treatment Facility). Another core objective of this project is to optimize the treatment performance of the pond system (oxidation ponds through the AFTs) with respect to removal of cBOD, TSS, ammonia, and total nitrogen (TN). Due to the unique technical nature of this project, design teams will benefit from having expertise in the following areas:
Electrical systems
Structural/seismic
Process evaluation
Mechanical equipment replacement/refurbishment
Automation controls and instrumentation
Pipeline rehabilitation
CEQA documentation
SRF/WIFIA Financing
Geotechnical
Surveying
Operations and Maintenance
