SUBJECT/RECOMMENDATION:
Title
Approve a Work Order to Tetra Tech, Inc., for design, permitting, bidding, and construction phase services associated with rehabilitating the effluent sand filters at the City’s Marshall Street Water Reclamation Facility (MS WRF) 25-0008-UT, in the amount of $ 306,509.00, pursuant to RFQ 34-23, Engineer of Record (EOR) Consulting Services and authorize the appropriation officials to execute same.
Body
SUMMARY:
The MS WRF effluent filtration system includes 12 filter cells constructed of poured-in-place concrete. The system employs the Hydro Clear® pulsed-bed sand filter process. Sand filters are a critical component of the wastewater treatment process, providing the final stage of particulate removal before effluent is discharged. By filtering out suspended solids and reducing turbidity, they help the facility maintain effluent quality and ensure compliance with state and federal water quality standards.
A recent Evoqua inspection report and EOR site visit identified several deficiencies impacting performance, including sand media loss, damaged underdrain components, corrosion of valves and actuators, and limitations with the SCADA interface.
The purpose of this project is to remove the existing filter media, clean and inspect the fouled media bed, and replenish it with new media. Additionally, it involves repairing damaged components and upgrades to the control panel and SCADA system. Tetra Tech will provide design, permitting, bidding, and construction phase services associated with the rehabilitation of the effluent sand filter system.
Tetra Tech was selected based on the qualifications of their professional staff and past performance on similar projects. They are known for delivering quality work and have specific experience with Clearwater’s facilities.
Design is anticipated to be completed within approximately 120 days from the date of council approval.
The City of Clearwater Public Utilities Department is responsible for owning, operating, and maintaining the MS WRF.
