Staff Recommendation: Move that the Council approve Amendment #12 to Contract #20170132 for the Design Services for the Westport Wastewater Treatment Facility Expansion with CHA Consulting, Inc. f/k/a Reiss Engineering, Inc.
Alternate Recommendations:
1. Move that the Council amend the recommendation and approve Amendment #12 to Contract #20170132.
2. Move that the Council not approve Amendment #12 to Contract #20170132 and provide staff with direction.
Background: The Westport Wastewater Treatment Facility is permitted to treat up to 6.00 million gallons per day (MGD) of wastewater using biological processes that meet secondary treatment standards of 20 mg/L for both Biochemical Oxygen Demand (BOD) and Total Suspended Solids (TSS), with no current limits for Total Nitrogen (TN) or Phosphorus (P).
In the USD’s continuing efforts to meet our goals for high-quality infrastructure and environmental stewardship, this project will provide enhanced treatment to achieve high level disinfection (HLD) with effluent limits of 10 mg/L TN and 3 mg/L P. As such, the City engaged CHA Consulting, Inc. f/k/a Reiss Engineering, Inc. to design system upgrades and prepare construction plans to meet these new standards.
Following the initial design phase, FDEP awarded the City of Port St. Lucie Utility Systems Department (USD) $35 million in grants to further reduce nutrient levels to 3 mg/L TN and 1 mg/L P to meet advanced wastewater treatment (AWT). The FDEP grant positions USD as a leader in proactively meeting future regulatory requirements.
This Amendment will support CHA Consulting, Inc. f/k/a Reiss Engineering, Inc., in completing the expanded design and assisting with implementation of the additional treatment requirements.
Issues/Analysis: Because Amendment #12 increases the Contract by more than $99,999.99, City Code of Ordinances, Section 35.09(b) requires City Council approval. Therefore, staff is requesting Council approve the Amendment. Staff has reviewed the Amendment and finds it to be fair and reasonable.
Financial Information: Funds are appropriated in the Utility CIP Fund / Westport WWTP / Improvements O/T Building (#448-3512-563000-21USD006P-Design-City).
Special Consideration: N/A.
Location of Project: Westport Wastewater Treatment Facility.
