EXECUTIVE SUMMARY
The District received $800,000 of American Rescue Plan Act (ARPA) funds through a Memorandum of Understanding with Napa County for the replacement of the main wastewater collection and storage tank at Sewer Lift Station A on February 8, 2022. The tank requires replacement due to deterioration of interior and exterior coatings, widespread pit corrosion along the wall panels, and corrosion of the metal roof dome - all caused by long-term sewer gas build-up in the tank above the high water line. A Request for Qualifications / Proposals (RFQ/RFP) solicitation for design services related to the replacement of the tank with a tank more suited to the highly corrosive nature of raw sewage, was publicly advertised on June 21, 2022. Two (2) engineering consultants submitted proposals by the July 28, 2022 deadline. GHD, Inc. ranked highest amongst the proposals submitted. Staff recommends approval of a Professional Services Agreement effective September 13, 2022 and expiring one year following completing the scope of services.
