Water Use Allocation Credit for the City of Boynton Beach
A. Background
The purpose of this scope of work is to attempt to obtain water use allocation credit for
replacement of existing golf course irrigation uses by reclaimed water and the use of ASR at
the City of Boynton Beach. The City of Boynton Beach currently provides wastewater to the
South Central Regional Wastewater Treatment and Disposal Board (SCRWWTDB) for
treatment and disposal. Both the cities of Boynton Beach and Delray Beach sit as the Board of
the SCRWWTF. In turn SCRWWTF provides reclaimed water to five golf courses within ithe
City of Boynton Beach service area with a commitment of 1.752 MGD on an average day
basis. In reality, the amount of reclaimed water usage has exceeded this quantity during the
dry season according to the South Florida Water Management District (SFWMD). In the
future, the City plans to provide reclaimed water to an additional 12 sites for an average day
commitment of .68 MGD.
The five golf courses are to the west and up gradient of the existing Eastern Water Plant and
wellfield, and southeast and downgradient of the Western Water Plant and wellfield. The
Western wellfield is located in the 16 ft NGVD basin of LWDD and the Eastern Wellfield is
located downgradient of the 8.5 ft. NGVD basin of LWDD. The five golf courses are located
in either the 8.5 ft or 12.5 ft NGVD basins.

When the City of Boynton Beach implemented reclaimed water usage through the
SCRWWTDB, all five of the golf courses were in existence and using water. These five golf
courses by virtue of their reclaimed water use have made available a significant amount of
water within basins of the Lake Worth Drainage District (LWDD).
The City of Boynton Beach currently has an annual allocation of 7,844 million gallons (MG)
and a maximum monthly allocation of 741.4 million gallons (MGM) from the Biscayne aquifer
under water use permit 50-00499-W. One existing and one proposed ASR well are noted.
According to the water use permit staff report, the City has proposed the completion of a
reverse osmosis (RO) treatment plant, however, no allocation is provided in the permit for
withdrawals for the RO plant and no allocation is given for withdrawals from the Floridan
aquifer.
The SFWMD has limited the City to dry season withdrawals from the Biscayne aquifer
(January through May) to 2325 MG not to exceed 465 MGM (15.5 MGD) after July 1, 2008.
Wet season withdrawals from the Biscayne wells (June through December) are limited to 5522
MG not to exceed 771 MGM. The combined total of these (7847 MG) is slightly more than the
total allocation of 7844 MG to meet 2010 projected finished water demands.
The City's allocation prior to the allocation granted in 2003 was 5,425 MG (14.86 MGD) with a
max day of 20.66 MG. The City's new allocation under its most recent permit is 7,844 million
gallons (MG) with a max month of 465 MG (15.5 MGD) after July 1, 2008. Since the City's
new allocation only provides for a dry season withdrawal of 15.5 MGD after July 1, 2008, this
means that by virtue of the new permit the City received a total decrease in allocation for the
dry season of about 5 MGD even though about seven years of additional growth was
projected.
The threat of salt water intrusion has been recognized at the Eastern Water Plant and the
SFWMD has limited it to 240 MGM (8.0 MGD). This means that during the dry season
withdrawals from the Western wellfield are limited to about 7 MGD on a maximum month
basis after July 1, 2008, if the Eastern wellfield is pumping its maximum amount.
Increases in withdrawals at the Eastern wellfield may be possible. SFWMD has indicated that
"Withdrawals from the Eastern Wellfield shall be limited to 240 MGM (8.0 MGD). If the
permittee provides additional information which demonstrates that an increase in
withdrawals will not potentially cause upcoming and/ or saline water intrusion and
otherwise meets the conditions of permit issuance, a modification to this limiting condition
shall be issued by staff."

CDM proposes that the City approach SFWMD with a request for 23 MGD (692 MGM) on a
dry season max month basis based on credit for both the City's use of reclaimed water and
ASR. The basis for the allocation credit is actually calculated in the 2003 staff report for the
existing permit and is as follows. Based on the 2003 SFWMD water use staff report, the basis
for the City's allocation of water from the Biscayne aquifer is the amount of water use
projected by the Lower East Coast Water Supply Plan (LECWSP) for 2005. This amount is
5,657 MGY (15.5 MGD). The staff report indicates that future water use projected for 2008 is
in excess of this amount (7380 MGY; 20.22 MGD). The staff report points out that the 2008
projected withdrawal is 1723 MGY (4.72 MGD) over the amount of use, 5,657 MGY projected
by the LECWSP for 2005.
SFWMD staff recognized that the Biscayne aquifer withdrawals do not impact the regional
system on a 1 to 1 basis and that of the groundwater pumped a portion is derived from local
groundwater storage and a portion is from seepage from LWDD canals. According to the
staff report, using the SFWMD's LECWSP sub-regional groundwater models, SFWMD
estimated that approximately sixty five percent of the water pumped in the vicinity of the
City's Western Wellfield is derived from seepage out of the surrounding LWDD canals
during a 1 in 10 year dry season maximum month. The staff report indicates that assuming
that all of the 1723 MGY is produced from the Western Wellfield would translate to
approximately 1120 MGY of additional seepage from the L WDD canals.
SFWMD staff evaluated the utility's pumpage data for the years 1999, 2000, and 2002 to
determine the ratio of wet season to dry season pumpage in order to identify how much of
the 1120 MGY of seepage would occur during the dry season. Based on this analysis, 56.8% of
the water is pumped during the wet season months (June through December) and 43.2%
during the dry months (January through May). Therefore approximately 484 MG will occur
during the dry season when water supply in the canals is being augmented from the regional
system. It is this additional regional system water that SFWMD staff examined in order to
determine consistency with the MFL recovery strategy.
The SFWMD staff performed an evaluation of alternative sources implemented by Boynton
Beach to offset the potential regional system discharges if the City were to withdraw the 2008
demand of 7380 MGY. During the dry season, an average of 4.4 MGD of irrigation water
supply that used to be directly withdrawn from the LWDD canals is being offset by the use of
reclaimed water (Page 10 of the July 23,2003 SFWMD staff report). The goIf courses that are
now using reclaimed water were modeled in CERP and the LECWSP as being supplied from
direct LWDD canal withdrawals. As a consequence of the use of reclaimed water by these
goIf courses the demands on the regional system that were considered in the CERP and
CDIVI
Page 4
regional system due to the City's 2008 projected water use (7380 MGY; 20.22 MGD) by 184
MG.
In addition, as another source to offset the excess in regional system influences, the utility has
an active ASR well in place that was not considered as a dry season source of water in the
LECWSP. During the dry season months of 2002,120 MG (800,000 gpd average) was
recovered. The staff report indicates that the recovery of water stored during the wet season
directly reduces the pumpage from the Biscayne Aquifer during the peak demand months in
the dry season, consequently reducing the influence on the regional system from what was
projected to occur in the LECWSP. Assuming 65% of this reduced demand would have been
from L WDD canal seepage had the water been pumped from Biscayne aquifer wells instead
of the ASR well, the ASR well reduces the dry season seepage demands by 78 MG. The City
is also adding a second ASR well in the near future that will further reduce dry season
pumpage of the Biscayne aquifer and associated seepage from the LWDD.
Combining the above analyses of both dry season reclaimed water use and ASR at the current
level, a total of 738 MG of offset within the LWDD canals occurs during the dry season
compared to the projected 2008 withdrawal of 7380 MGY (20.22 MGD) and projected increase
of seepage from the LWDD canals of 484 MG at the latter withdrawal.
The 738 MG offset during the dry season presented above should justify an increase of 1135
MG in withdrawal (738 MG/ .65) during the dry season. This is equivalent to 227 MGM or
about 7.5 MGD increase in allocation.
Based on these considerations, a max month of 23 MGD (692 MGM) during the dry season
from the Biscayne aquifer is consistent with District permit criteria for MFL water bodies and
is consistent with the LECWSP and CERP. This takes into consideration a post-July 1, 2008
dry season max month of 465 MGM plus an offset of 227 MGM during the dry season for a
total max month of 692 MGM (23 MGD) from the Biscayne aquifer.
The ability to obtain an increased allocation from the Biscayne aquifer associated with credit
for reclaimed water use has recently been complicated by potential failure of the Lake
Okeechobee dike during high water periods. This would not be due to the rationale for credit
for reclaimed water use but rather the fact that the historical use of fresh water from the
Biscayne aquifer may not be available. The potential for failure of the Lake Okeechobee dike
has led the US Army Corps of Engineers to indicate that the Lake will have to be held at a
lower elevation which means less storage available for public water supplies along the east
coast. As a consequence utilities may not have access to historical amounts of fresh water
from the regional water supply system. Lake Worth Drainage District's allocation of water
for utilities along the east coast of Palm Beach County may not be supported by the SFWMD;
N:lOOOOIWLB2900.doc
CDIVI
Page 5
rather L WDD and dependent utilities may be required to go into water shortages frequently
during the dry season as a consequence of decreased storage. The use of reclaimed water
may not be sufficient to overcome the regional water supply deficit to allow SFWMD
managers the ability to allocate additional water.
B. Scope of Work
Task 1. Collect SFWMD permit data on five golf courses
CDM will determine whether the five golf courses that are receiving reclaimed water still
have water use permits and allocations from the South Florida Water Management District.
CDM will search, obtain and evaluate whether there are existing water use permits for the
five golf courses from the SFWMD. CDM will determine if the five golf courses still have
intakes into adjacent canals of the Lake Worth Drainage District. The existence of
permits, allocations and canal intakes for the five golf courses will be negotiation points in
obtaining credit for reclaimed water use.
Task 2. Obtain reclaimed water use records
CDM will obtain reclaimed water use records for each of the five golf courses from
SCRWWTDB for the past 24 months if available. CDM will cross check to determine if the
contracted amounts of reclaimed water are actually being used (1.75 MGD) and if the 4.4
MGD of reclaimed water use indicated in the City's last SFWMD water use staff report is still
applicable, or whether that amount has actually increased.
Task 3. Meet with SFWMD to discuss obtaining allocation credit
CDM will arrange up to two meetings with SFWMD staff for the purpose of discussing
allocation credit for the City of Boynton Beach. The objective of the meetings will be to obtain
credit for the reclaimed water usage which the City has supplied to five golf courses along
with ASR allocation credit as described above. In terms of the current allocation, the purpose
would be to increase the allowable dry season (January through May) monthly withdrawal
from the Biscayne aquifer wells from 15.5 MGD (465 MGM) which is the restriction after July
1, 2008 to approximately 23 MGD (692 MGM) given credit for reclaimed water and ASR.
