BRADENTON -- The City of Bradenton Department of Public Works & Utilities is soliciting Statements of Qualifications (SOQ) from professional firms qualified to provide design and consulting services to support of the City’s Potable Water ASR Program.
The City intends to award to the most qualified firm a continuing services contract to employ as projects under the Potable Water ASR program develop and when the City is in need of professional services related to the program. The contract shall be awarded for an initial period of three years, with a potential for two, 1-year extensions. SOQs must be received by 2 p.m. Aug. 23.
The City’s ASR Program currently includes one (1) finished water ASR well, located at our high service pump station, equipped with membrane degasification pretreatment for arsenic mobilization control. The system utilizes 16 Liqui-Cel® membranes contactors operating under pressure with nitrogen sweep gas to achieve dissolved oxygen concentrations of under 10 parts per billion (ppb) at a process flow rate capacity of 700 gallons per minute (gpm).
The degas system is currently being upgraded/expanded to provide a pretreatment process flow rate of 925 gpm, while maintaining the oxygen removal efficiency. An operational permit for this ASR is in the final stages of preparation by FDEP and is expected to be issued and be in effect prior to the execution of the contract solicited under this RFQ.
Separately, the City has recently completed a feasibility study related to development of a second ASR well field to be located at the City’s water treatment plant (WTP). The study recommends the pursuit of the following:
Expansion of the ASR system to provide seasonal recovery of a minimum of 560 MG/year of treated surface for distribution to the potable water system for use minimizing dry weather drawdowns in our existing surface water reservoir, and Potential future expansion of the ASR system to allow for wet year recharge of up to 960 MG/year to accommodate recharge during excessively wet years for use in future dry years.
