BACKGROUND:
Staff requests approval of SA No. 2 with Ardurra to provide engineering and technical services for
the Keystone Heights WRF Facility Expansion Project.
CCUA operates and maintains the KH WRF that serves predominately commercial portions of the
Keystone Heights service area. The KH WRF has a permitted annual average daily flow(AADF)
treatment capacity of 0.074 million gallons per day (mgd) and discharges treated water to rapid
infiltration basins (RIBS) that have a permitted AADF capacity of 0.200 mgd. The Keystone
Heights area is a prominent recharge area, so this water is beneficially reused through recharge.
The plant headworks, clarifier,and electrical components need rehabilitation.In addition, CCUA's
KH WRF Capacity Analysis Report identified the need for expansion of this facility within the
next 24 months to serve requested service needs in the area. The airport authority has also
expressed interest in developing capacity in the area.
Ardurra recently completed the Conceptual Evaluation and Basis of Design Report (BODR) to
increase the capacity of the KH WRF which included evaluating the range of growth potential in the
area, conducting a regulatory analysis, evaluating condition and rehabilitation needs of existing unit
processes and equipment at the KH WRF, and developing and evaluating improvement and
expansion alternatives. Based on this analysis, the KH WRF capacity will be expanded to 0.200
mgd AADF and converted to a 4-stage nutrient removal process. The design will include
provisions to meet high level disinfection in the future, if required by the Florida Department of
Environmental Protection(FDEP). The attached scope and fee proposal provides the details of the
work required to complete the design of the expansion and bid the project to the contracting
community.
The proposal also includes funds to identify and assist with acquisition of potential grant funding.
BUDGET:
The 5-year Capital Improvements Plan includes $11.1 million for the rehabilitation and expansion
of the KH WRF. These funds are sufficient to complete design,bid,and construction of the project.
CCNA:
CCNA, F.S. s. 287.055, does apply to the use of a consultant under continuing contract. Staff
negotiated this Supplemental Agreement for the professional services at a compensation which the
agency determines is fair, competitive, and reasonable in compliance with F.S. s. 287.055.
RECOMMENDATION:
