1 North Florida Regional Water Supply Partnership NFSEG Model Historic Water Use Jim Gross, P.G., SJRWMD Carlos Herd, P.G., SRWMD September 23, 2013

2 Water Use Data April 22, 2013 presented 2001 and 2009 data Important to perform analysis on water use trends FoundaHonal for populahon and demand projechons Needed for calibrahon of numerical groundwater models

3 PopulaHon and water demand projechons Current populahon, populahon served (PWS), and water use is the starhng point for public supply water demand projechons In simple terms, future public supply demand is future populahon served mulhplied by latest five year gpcd

4 NFSEG Model Water Use o and 2010 Historical Water Use o Needed for steady state model calibrahon o All 6 water use categories o Groundwater use only o SpaHal distribuhon by stahon/well o SJRWMD and SRWMD Complete o Georgia, NWFWMD & SWFWMD Underway

5 SJRWMD Water Use o Data Sources o Public Supply o Metered EN50 and Reported DEP MOR data o Permit specific water use o Domes@c Self- Supply & Small U@li@es o DomesHc Self- Supply o EsHmated values obtained from District AWUS Reports o County- wide water use o Small UHliHes o Metered EN50 and Reported DEP MOR data o Permit specific water use

6 SJRWMD Water Use, Con t. o Data Sources, Con t. o Agriculture o Metered EN50 data o Permit specific water use o Commercial / Industrial / Ins@tu@onal & Mining / Dewatering o Metered EN50 data o Permit specific water use o Landscape / Recrea@on / Aesthe@c o Metered EN50 data o Permit specific water use o Power Genera@on o Metered EN50, Reported DEP MOR data and Survey data o ConsumpHve GW use only o Permit specific water use

7 SJRWMD Water Use, Con t. o Data Sources, Con t. For uses other than Public Supply and Power GeneraHon, amount of groundwater use was eshmated where there are mulhple sources. o Percent of GW AllocaHon to Total AllocaHon applied to Total Water Use Example: Total AllocaHon 1.00 mgd GW AllocaHon 0.50 mgd % GW = 50 % Total Water Use 0.80 mgd GW Use 0.80 mgd * 50 % = 0.40 mgd

8 SRWMD Water Use o Data Sources o Public Supply o Reported DEP MOR data o Permit specific water use o Domes@c Self- Supply & Small U@li@es o DomesHc Self- Supply o values obtained from interpolated USGS 2005 and 2010 Reports o 2010 values obtained from USGS 2010 Report o County- wide water use o Small UHliHes o Reported DEP MOR data o Permit specific water use

9 SRWMD Water Use, Con t. o Data Sources, Con t. o Agriculture o values obtained from interpolated USGS 2005 and 2010 Reports o 2010 values obtained from USGS 2010 Report o County- wide water use o Commercial / Industrial / Ins@tu@onal & Mining / Dewatering o values obtained from interpolated USGS 2005 and 2010 Reports o 2010 values obtained from USGS 2010 Report o County- wide water use o Landscape / Recrea@on / Aesthe@c o values obtained from interpolated USGS 2005 and 2010 Reports o 2010 values obtained from USGS 2010 Report o County- wide water use o Power Genera@on o values obtained from interpolated USGS 2005 and 2010 Reports o 2010 values obtained from USGS 2010 Report o County- wide water use

10 SRWMD Water Use, Con t. o Data Sources, Con t. USGS does list groundwater use by county, so no addihonal split is required. Linear InterpolaHon Example: (2010 GW Use 2005 GW Use) / GW Use 2010 GW Use 5.00 mgd 2005 GW Use 1.00 mgd 2006 GW Use (5.00 mgd 1.00 mgd) / mgd = 1.80 mgd *Of note For this effort, SRWMD classified all permits into use types, consistent with pending CUP consistency efforts.

11 Water Use Summary Historic Groundwater Use Category Public Supply DomesHc Self- Supply & Small UHliHes Agriculture Commercial / Industrial / InsHtuHonal & Mining / Dewatering Landscape / RecreaHon / AestheHc Power GeneraHon Total Water use shown in million gallons per day Water use for DSS does include NWFWND and SWFWMD Water use for other use types does not include NWFWMD, SWFWMD or Georgia

12 SJRWMD Water Use DistribuHon o PS, AG, CII/MD, LRA, PG and Small U@li@es o Permit specific water use is distributed to permit specific stahons o Water Use distributed evenly o ExcepHon is PS that has mulhple well fields with different allocahons o Water use distributed to well fields by % allocahon o Then water use by well field distributed evenly to well field stahons

13 SJRWMD & SRWMD Water Use DistribuHon o Domes@c Self- Supply o County- wide water use is distributed to parcel level equally o DSS Parcels idenhfied in two ways o Residences outside public supply service area boundaries are DSS o Model builder uses zoning classificahons and DOR codes o Residences inside public supply service area boundaries o SJRWMD - Well complehon reports that have been processed o SJRWMD - UHlity specific billing data when available o SRWMD - Need to process well complehon reports o SRWMD - Need uhlity specific billing data

14 SRWMD Water Use DistribuHon o Public Supply and Small U@li@es o Permit specific water use is distributed to permit specific wells o Water Use distributed evenly

15 SRWMD Water Use DistribuHon, Con t. o AG, CII/MD, LRA and PG o County- wide water use is distributed to wells o Each well has an allocahon and specific use type o % of total county allocahon for each use type was assigned to each well with like use o County- wide water use for each use type mulhplied by % of allocahon for each well with like use type Example: Alachua County Total AG AllocaHon mgd AG Well X AllocaHon 0.38 mgd Well % of Total County AllocaHon Alachua County Total AG Water Use mgd 2006 AG Well X Water Use * 1.10 % = mgd

16 SpaHal DistribuHon o and 2010 water use by stahon / well linked spahally to point shape file o Table format and GIS format distribuhon delivered to Bureau of Engineering and Hydrologic Sciences 4/8/13

17 & 2010 SpaHal Water Use DistribuHon PS, AG, CII/MD, LRA, PG, Small UHliHes

18 & 2010 SpaHal Water Use DistribuHon DomesHc Self- Supply

19 & 2010 SpaHal Water Use DistribuHon All Water Use Categories

20 Next Steps o Finalize & incorporate Georgia data o Finalize & incorporate SWFWMD & NWFWMD data o Steady state model first, then move to transient data

21 North Florida RWSP o NFSEG data correlahon to N FL RWSP o SJRWMD & SRWMD data will be used for: o Historical trends used as basis for projechons o PS: used in average per capita o 2010 base year for water resource analysis o 2010 versus future simulahons o Answer whether we can meet future demands with exishng sources
