SUBJECT/RECOMMENDATION:
Title
Approve a work order with Black and Veatch of Tampa, FL, for implementation of full-scale pilot testing at the Marshall Street Water Reclamation Facility (26-0011-UT) in the not-to-exceed amount of $376,192.00 pursuant to RFQ 34-23 and authorize the appropriate officials to execute same.
Body
SUMMARY:
Black & Veatch is one of the firms selected under RFQ No. 34-23, Engineer of Record Consulting Services, and will provide engineering and consulting services for implementation of a full-scale pilot test to improve the effluent quality at the Marshall Street Water Reclamation Facility (MS WRF). Black & Veatch was selected for this work based on their extensive experience and prior analysis of the Trihalomethane (THM) formation at MS WRF.
MS WRF is the oldest of the City of Clearwater’s three water reclamation facilities. The disinfection process at MS WRF consists of an inner and outer Chlorine Contact Chamber (CCC) with a mixing chamber. When chlorine reacts with organic matter in the wastewater effluent, disinfection byproducts such as THMs are formed. The Florida Department of Environmental Protection (FDEP) regulates the allowable limits for various THM compounds.
The City observed elevated levels of THMs, specifically dibromochloromethane (DBCM), and authorized Black & Veatch to perform an updated study under project 24-0075-UT, MS WRF THMs, building upon a previous study completed in 2021. Following completion of the updated study and associated bench-scale testing, the Public Utilities Department intends to implement the consultant’s recommendations, including a full-scale pilot testing involving the use of sulfuric acid within the CCC.
Services under this work order include project management, data collection and analysis, the development of a full-scale pilot work plan, FDEP coordination and support, pilot implementation support, and preparation of a technical memorandum summarizing the background, testing performed, evaluation of effectiveness, and recommendations for future steps. The total cost of the proposed project is not expected to exceed $376,192.00.
Utilizing the same consultant provides continuity with the previously completed THM evaluation and allows the City to efficiently implement and evaluate the recommended pilot testing approach.
APPROPRIATION CODE AND AMOUNT:
3277327-530100-M1905
Funds are available in capital improvement project 327-M1905 Marshall Street Plant R&R to fund the work order. This project is funded by revenues from the Water and Sewer Utility Enterprise Fund.
STRATEGIC PRIORITY:
To further the Council’s Strategic Plan to achieve High Performing Government by maintaining quality effluent at Marshall Street Water Reclamation Facility, a public infrastructure of the City, through systematic management efforts.
