Pinellas County Water System
CUP No. 202673
1956 The Eldridge-Wilde Wellfield was put into production within
an 1,800 acre tract of leased property in northwest Hills-
borough County and northeast Pinellas County with nine -
12" wells and a design capacity of 15 mgd.
1972 The wellfield was expanded to a total of 58 production
wells and a pumping capacity of 90 mgd. However, actual
production capacity in 1972 was estimated to be 62 mgd.
August 1972 At the regular SWFWMD Public Hearing, a representative
from Black, Crow and Eidsness reported to the Governing
Board that the Eldridge-Wilde Wellfield withdrawals were
increasing at a rate of 2 mgd per year and fast approaching
an upper limit to its capability to meet the water require-
ments of Pinellas County. The Govering Board recommended
that perhaps Pinellas County should look at the Cypress
Creek area to meet future demands.
December 1972 Because the Eldridge-Wilde Wellfield had approached a state
of overdevelopment, the Governing Board of SWFWMD issued
Order No. 72-4 which required that Pinellas County construct
monitor wells, undertake a monitoring program, perform a
pump test and show progress towards developing and imple-
menting plans for additional sources of water supply.
July 1973 The Governing Board of SWFWMD issued Order No. 73-2R ex-
tending the completion time for observation and monitor
wells to October 1973 and continued the Hearing date to
September in order for Pinellas County to present further
September 1973 Because of the necessity for regulating withdrawals of
water from Eldridge-Wilde, SWFWMD Order No. 73-3R was
passed. The stipulations included an average daily with-
drawal not to exceed 36 mgd cumulatively from September 1,
1973, and 28 mgd after April 1974. The maximum daily was
not to exceed 44 mgd. Also ordered were aquifer tests
in the wellfield, development of additional wells and
pumping tests near East Lake Road, reducing runoff, re-
charging the wellfield shallow sands with excess water
and water conservation measures and programs.
November 1973 The average annual withdrawal quantities for Eldridge-
Wilde were amended on SWFWMD Order No. 73-5R. Withdrawals
were to decrease from 36 mgd on August 1, 1973, to 28 mgd
on October 1, 1974. The maximum daily quantities were to
remain at 44 mgd until October 1, 1974, or until regulatory
levels could be set.
June 1974 Order No. 74-2R was issued by SWFWMD to amend completion
dates on certain observation wells, production wells, in-
stallation of conserving water closets in Pinellas County
y and construction of weirs to reduce runoff which were stip-
ulations in Orders No. 72-4 and 73-3R.
1974 Order No. 74-6R was issued to amend Orders No. 73-3R and
73-5R in regards to weekly reports on withdrawals from

August 1974 Order No. 74-9R amended the number of production wells at
East Lake Road from eight to six and the completion date
from August to October 1974.
October 1974 Pinellas County and the Southwest Florida Water Management
District entered into an agreement,.Stipulation 74-1, in
which Pinellas County agreed to regulate the Eldridge-Wilde
Wellfield pumping so as to not cause the cumulative weekly
average elevations of the potentiometric surface of the
Floridan Aquifer to drop below set regulatory levels on
four specified monitor wells. Pinellas County was to con-
struct two monitor wells by May 1975 and collect water level
data for use by the District in reevaluating the regulatory
levels which were set.
November 1974 Stipulation No. 74-1 was written into, and approved, as
Final Order No. 74-10R.
January 1975 A program for issuance of permits authorizing the consump-
tive use of water was implemented -commencing January 1, 1975.
All existing users as of January 1, 1975, were given until
December 31, 1976, to file their applications.
December 1976 Pinellas County filed application No. 7602673 for a CUP for
the continued use of water in the quantities existing prior
to January 1, 1975. The application was for a combined
average annual withdrawal of 35,243,888 gallons per day
with a maximum combined withdrawal rate of 59,300,000 gal-
lons per day from 58 production wells. Of the requested
average annual quantities, 96% was for public supply, 3%
for on-site irrigation and 1% for augmentation to Lake Dan
located within the wellfield.
February 1977 A report entitled "Hydrologic Monitoring Program Report"
was completed by Black, Crow and Eidsness, Inc., outlining
the extent of the Eldridge-Wilde Wellfield monitoring pro-
April 1978 CUP No. 7602673 was issued to Pinellas County under Final
Order No. 78-26 by SWFWMD for a combined average annual
withdrawal of 35,243,888 gpd and a maximum day withdrawal
of 55,000,000 gpd. Other conditions of the permit included
the modification of six monitor wells for chloride sampling,
regulation of pumping so as to not cause the cumulative
weekly average elevations of the potentiometric surface of
the Floridan Aquifer to be lower than set regulatory levels
on four monitor wells, weekly reports on pumping and main-
tenance of a flow metering system. The CUP was set to
expire on December 31, 1980.
