SUBJECT
Title
Reject all bids for the Wellhead Treatment Improvements Construction for Pump Stations 117 and 284 (Bid File 3747) (Council District 2 and County Island within)
Body
RECOMMENDATIONS
Staff recommends that City Council reject all bids for the Construction of Wellhead Treatment Improvements for Pump Stations 117 and 284.
EXECUTIVE SUMMARY
The Department of Public Utilities, Utilities Planning & Engineering (DPU), solicited Contractor services to construct wellhead treatment improvements at Pump Station 117 (PS 117) and Pump Station 284 (PS 284).

The project is funded through a State Revolving Fund loan and the loan amount is not sufficient to fund the award of a Contract. Staff therefore recommends rejection of all bids for the Project.
BACKGROUND

PCE is a colorless liquid solvent associated with dry cleaning, textile operations, and metal degreasing.
This project will construct a common well head treatment facility at PS 117 to treat both wells PS 117 and PS 284. Due to limited space at PS 284, a raw water pipeline needs to be installed to convey water to PS 117 for centralized treatment.
