BACKGROUND
The Spencer's Crossing Water Treatment Plant (WTP) is an existing 4.488 million gallon per day(mgd)
maximum daily flow(MDF)facility located at 4426-1 Hanging Moss Dr, Orange Park, FL 32073.The
existing WTP consists of three Upper Floridan Aquifer(UFA) wells, a 4,600 gallon per minute (gpm)
stand-alone tray aerator tower for hydrogen sulfide removal, a 0.53-mg glass fused steel ground storage
tank (GST), hypochlorite disinfection feed pumps and storage tanks, a 10,000-gallon hydropneumatic
tank, and a high service pump station (HSPS) with three horizontal split-case pumps including electrical
and instrumentation required to operate and monitor the facility.
to The site has additional open space for future GSTs and other improvements. It appears the existing St.
Johns River Water Management District(SJRWMD) Environmental Resource Permit(ERP), included
additional impervious area for future improvements upon initial review.
The AUTHORITY has requested CONSULTANT submit this Authorization for design, permitting, bidding
assistance, and construction management services for the addition of a new GST and improvements to
the existing HSPS as described in the Basis of Design outlined below.
BASIS OF DESIGN
The Spencer's Crossing WTP requires improvements to its existing infrastructure which include:
1. New GST including Associated Piping and Valving
