The existing WUP was issued in September of 1996 and is scheduled for renewal in 2006.The Jacaranda wells are located within the Intermediate/Upper Floridan Aquifer Systemand range in depth from 520 to 530 feet. Total dissolved solids (TDS) concentration in thewells ranges from approximately 2000 to 3000 mg/L, with sulfate being the majorconstituent. The existing RO membranes allow some raw water to be blended into the ROproduct stream while still meeting the secondary water quality standard of 500 mg/L ofTDS. Currently, raw water is blended with RO product water at approximately a 1 to 5 ratio.On the day of the facility site visit, the system was blending approximately 500 gpm of ROproduct water with 100 gpm of raw water to produce the finished water.The County recently acquired the permitted quantities for two additional wells, RO-9 andRO-10, after acquiring land that had an existing WUP. These two wells are not yetconnected to the Venice Gardens WTF, but they could provide additional flow in the future.2.3.2.1 Process DescriptionThe Venice Gardens WTF and Jacaranda Wellfield site are shown in Figure 2.7. Wells arelocated on the WTF site and to the south and east of the site. Figure 2.8 presents a processflow schematic of the Venice Gardens WTF. The facility’s treatment elements includegroundwater pumping, pH adjustment, anti-scalant addition, cartridge filtration, reverseosmosis, degasification, and disinfection. Figure 2.8 also shows the locations of chemicalfeed points. Like all other County WTFs, the Venice Gardens WTF utilizes free chlorine (inthe form of sodium hypochlorite) for primary disinfection and adds ammonia to formchloramines for residual disinfection. Treated water from the Venice Gardens WTF is storedin onsite ground storage tanks and is pumped to the southern and central portions of theCounty. The Venice Gardens WTF was equipped with a new SCADA system andWonderware computer software during the 2002 upgrade. Although the facility currently isincompatible with the rest of the water distribution system software, their system will beeasily integrated once the remaining WTFs and pumps stations are upgraded with newsoftware and automation and control equipment.Table 2.4 presents a summary of key process design criteria for the Venice Gardens WTF.A description of the process train is provided in the following sections.FINAL - August 31, 2005 23H:\Client\SAR Co_SAR\6873C00 WATER SUPPLY MASTER PLAN UPDATE\Deliverables\TM 2 - Water System Assets\Final\TM2 Final.doc
