42 The City of Boca Raton owns and operates facilities to withdraw, treat, store and distribute potable water. The service area consists of 35 square miles and includes residential, commercial, hotel/motel and institutional uses, as well as some contiguous areas within unincorporated Palm Beach County. In 2013, the Department distributed an average of 31 mgd treated water to a population of 128,728 yielding a daily use of 241 gallons per capita per day (gpcpd). Projected population growth through 2035 affords gallons gpcpd finished water demand Level of Service (LOS). The Department has a design storage capacity of approximately 25.5 MG equivalent to 198 gpcpd storage LOS when using the 2013 population estimates. The Department provides a water pressure LOS of 60 pounds per square inch (psi) in normal conditions and a minimum water pressure LOS of 20 psi under mechanical or drought conditions. The City's large potable water users (in no particular order) include: Boca Raton Regional Hospital, Boca Raton Resort and Club, Florida Atlantic University, Boca Technology Center, and Town Center Mall. The sole source of the raw water is the Biscayne Aquifer. The aquifer is recharged by local rainfall and supplemented by water diversions controlled by the South Florida Water Management District (SFWMD), including Lake Okeechobee, Water Conservation Area No. 1, Hillsboro Canal and Lake Worth Drainage District (LWDD) canals E-2-E, E-3 and E- 4 and various lateral canals. Fifty-one wells withdraw water from depths of 110 to 120 feet. The water is transmitted to the Boca Raton treatment plant located on Glades Road just east of lnterstate-95. The water is treated in either the lime softening plant (30 mgd capacity) or the membrane softening plant (40 mgd capacity). The water produced in each plant is blended before being pumped into the water distribution system. The water distribution system includes: million gallons (MG) of finished water storage capacity; 585 miles of pipe; -5,600 fire hydrants; and -35,000 water meters. The current 2034 projected population of 137,117 will require an average daily raw water demand of mgd to produce mgd potable water. The installed wellfield capacity for the City of Boca Raton Utility Services Department (CBRUSD) is approximately 86.3 MGD with a permitted maximum month withdrawal of MGD. Water treatment facilities to be utilized in the 2034 condition will be a 2:1 blend of lime-softening treatment and membra ne-softening treatment. The 2013 annual demand on the City's wellfields was billion gallons and the projected 2034 annual demand is billion gallons. Utilizing a 1:10 year drought demand (assuming 10% higher than average-day demand) the CBRUSD will have a surplus of more than 29.4 mgd raw water pumping capacity and more than 13.1 mgd treatment capacity. Pursuant to Consumptive Use Permit No W, the City of Boca Raton has a maximum annual allocation of billion gallons and a maximum monthly allocation of million gallons. The City is committed to meeting all existing and future customer demands for water quality and quantity, in an economical and efficient manner. 18 January 2015

Three additional wells were recently completed near the Northwest Wellfield. All of the wells in Boca Raton are telemetry controlled and withdraw water from the Biscayne aquifer, which is the source for most potable water supplies in southeast Florida. The aquifer lies from 0 to 300 feet below the ground surface and underlies the entire Boca Raton area. All wellfields are located within the City's service area. The wells are regularly serviced and pumped periodically to ensure operability and to determine if there is any bacterial contamination in the wells. Central Wellfield The Central Wellfield is comprised of one (1) well, known as 12W, and is located on the south side of Glades Road, directly across from the Glades Road Water 24 January 2015

49 Treatment Plant (WTP) located at 1301 Glades Road. Well 12W is rated for 1400 gpm which is a total capacity of 2 mgd. Northeast Wellfield The Northeast (NE) Wellfield is comprised of ten (1 0) operating wells, designated 13-E through 22-E and is oriented south to north along Northwest Fifth Avenue and the El Rio Canal (E-4) from NW 20th Street to just north of NW 40th Street (Spanish River Boulevard). The wells are all rated for 700 gpm (1 mgd) for a total capacity of 10 mgd. Southeast Wellfield The Southeast (SE) Wellfield is comprised of five (5) operating wells, designated 3E, 4E, 12E, 24E and 25E. 3E and 4E are located along NW 2nd Ave, between NW 6th Stand Glades Road, each rated for 700 gpm (1 mgd). Wells 12E, 24E and 25E are located along NW 4 Ave between Glades Road and just north of NW 20th St. 12E is rated for 700 gpm (1 mgd) and 24E and 25E are each rated for 1400 gpm (2 mgd). The total capacity of these Wellfield is 7 mgd. Both the NE and SE wellfields are connected through a 36-inch diameter raw water transmission main to the WTP. Southwestern Wellfield The Southwestern (SW) Wellfield has twelve (12) wells, designed 1W through 9W and 40W through 42W. The last 3 wells (40-42W) were constructed along West Palmetto Park Road in 1990s. Wells 1W through 9W were constructed along the E-3 Canal, which is oriented north to south from Glades Road to Camino Real. These wells pump raw water through a 48-inch diameter transmission main to the Glades Road Plant. The total capacity of the SW wellfield is 24 mgd. Northwest Wellfield The Northwest (NW) Wellfield has thirteen (13) production wells, designated 13W through 25W. Wells 13W through 15W are oriented from southwest to northeast in the median of Potomac Road; wells 16W through 20W are oriented from south to north along the E-3 Canal; wells 25W, 24W, 20W through 23W are oriented from east to west; respectively, along Yamato Road. Each well has a rated capacity of 2.0 MGD or 1,400 GPM for a total capacity of 26 mgd. (26W was part of this wellfield but was abandoned and sealed in 2013.) The Yamato Road generator building next to Well 20W was provided to supply emergency power to wells 17W through 25W in the NW Wellfield, along with housing the motor control centers for these wells. This station includes a telephone communication line connected directly to the operations control room at the WTP. Northern Wellfield The Northern (N) Wellfield has eight (8) production wells, designated as 27W, 29W, 30W, 32W, and 35W through 37W. The wells were constructed in the 25 January 2015

74 In addition to the potable water conservation strategies and techniques discussed previously, the City of Boca Raton has provisions for conserving potable water resources through the implementation of its reuse program, Project IRIS. The City of Boca Raton Utility Services Department currently treats an average of approximately 14 MGD of influent wastewater at its wastewater treatment plant WWTP). The WWTP is rated at 17.5 MGD. A 17.5 MGD reclaimed water production facility is co-located next to the WWTP at the Glades Road site. The reclaimed water production facility currently treats an average of 7.0 MGD. The remaining balance of the effluent is discharged via ocean outfall. Because of off-sets resulting from planned reclaimed water projects, the City of Boca Raton was granted a CUP with an allocation above the 2007 baseline allocation. The potable water demand in excess of the 2007 baseline allocation is projected to occur in mid-2020 o The completion of several reclaimed projects has already resulted offsets that have created a positive balance to the regional system. o This positive balance has been realized well before the potable water demand exceeds the 2007 baseline allocation. o Total water saved on the regional system by the recla imed projects over the 20 year period is over 40 billion gallons. The City implemented and completed an aggressive reuse plan and has become a fully operational reuse system comprising 100 percent of our annual average daily flow for reuse activities authorized by the FDEP.
