The following information is preliminary in nature based on the executive summary provided with the
proposal and cursory examinaioa of the proposal 1 h information is subject to change based on a
complete evvauarion of the proposal. The water cost presnted below is based on a bae plant em of 20
milian gallon per day (mgd) as defined in the request for proposals and does not nmoesarily represt t the
lest eWot option of delivemd water as prsentod by the developr tam
The Team
Skmn & Webster, TIC The Indusrial Company, and Citiuzu Uilities Company. intend to form a limited
liability company (LLC) to develop the project. The team anticipate potential participation by subsidiaries
of Tampa Elotric Company (TECO)and Poscidon Resourn s in the LLC.
Pbert Siting
The team proposes to develop a seawatcr dcsalinatio plant t TECO's Big Bend electric generating sit on
HiUlborouh Bay in southem Hillborough County. The property is owod by Tampa Elccric and
suitable sorac is available o build a 50 million gallon per day (mgd) desalination plant. The present site

Desalination study gains steam

* Proposals for desalinated sea
water come in surprisingly low in
cost, making the option more

1ln.w St-i Writ.r
CLEARWATER Desalinated sea water,
once thought to be too expensive to play a role in
the expansion of the region's drinking water
supplies, is looking better and cheaper -
than anybody thought it could.
The West Coast Regional Water Supply Au-
thority, the largest water wholesaler in the Pinel-
las-Hillsborough-Pasco area, released numbers
Friday from five companies that want to build a
desalination plant that would add 20-million to
50-million gallons a day to regional drinking

water supplies, allowing for future economic
growth and easing the environmental strain on
areas around over-pumped well fields.
Though price is only one factor in whether to
build a plant, it is a crucial one. Predictions for
price had ranged from $3 to $4 per thousand
gallons, compared to $1 for the general whole-
sale price of ground water.
Only one of the proposals contained prices
anywhere near that high, The lowest projected
price was $1.54, and that came from a partner-
ship that includes a local company. Progress
Energy Corp., a subsidiary of Florida Progress.
"I was expecting something around $3," said
Don Lindeman, West Coasts deal project man-
ager. "The fact that it is cheaper certainly makes
it more promising."
The proposals envisioned a variety of sites for
the plant, including the area next to the Anclote

from 18
River power station in southern
Pasco, Anclote Road in north Pi-
nellas, the land next to the Higgins
power station on Old Tampa Bay
in the Oldsmar area of Pinellas
County and a site next to the Big
Bend power station on Tampa Bay
in southern Hillsborough County.
Construction costs ranged
from $69.3-million to $186.1-mil-
lion, and completion schedules
ranged from 21 to 35 months.
Because the proposals are so
complex and so voluminous,
choosing a winner assuming
West Coast decides to go the desal
route will be difficult. It is a task
not unlike comparing five different
automobiles from five different
manufacturers in five different
price ranges with five different
colors and five different options

packages and then trying to
decide whether to buy or to lease.
In addition to cost. West Coast
officials must look at each propos-
al's environmental impacts, engi-
neering, financing and operations.
"All the proposals have multi-
ple scenarios," Lindeman said.
"Because of economy of scale, the
larger the plant's capacity, the less
the water will cost. Under some of
the proposals, it is projected we
could get as much as another
$1.50 off the price."
One option for the bidders is to
accept $50-million in new-water re-
source development funds put on
the table by the Southwest Florida
Water Management District, or
Swiftmud, to defray construction
'The capital cost and the cost
of the water are both lower than
we've ever heard before, and low-
er still when you factor in the
Swiftmud money." said Gene

Schiller of Swiftmud, who sits on
the committee evaluating the pro-
posals. "'These numbers are truly
Swiftmud's -proposed Partner-
ship Plan for development of new
water resources could offer as
much as an additional $40-million
to help construct a desal plant,
which would bring the agency's
contribution to $90-million total.
But the Partnership Plan is still
under discussion.
"Obviously, that would bring
the price of water down still far-
ther," Schiller said. "The compa-
nies didn't factor in the additional
$40-million, though, because they
only wanted to use money already
approved for such a project, and
we don't know yet if the Partner-
ship Plan will fly."
The desalination proposals will
undergo another month of study,
then be presented to the West
Coast board in January.

Desalination price may

be lower than estimated

BROOKSVILLE Five proposals
to build a desalination plant put
the price per 1,000 gallons of
water at $1.50 to $3.98.
of The Tampa Tribune
Turning saltwater to fresh -
long thought as a necessary step
in solving Tampa Bay's water
problems could cost roughly
half what was expected and
might be lower.
Proposals from five corporate
teams to build a desalination
plant show the price of water
ranging from $1.50 per 1,000
gallons to nearly $4 per 1,000
The wholesale price of
groundwater for the West Coast
Regional Water Supply Authori-

ty, which released an analysis of
the proposals on Friday, is about
$1 per 1,000 gallons for utilities
around Tampa Bay serving 1.8
million people.
And it's possible the price for
desalination could be even less.
Those costs are for the small-
est desalination plant West Coast
is looking to build. Enlarging the
plant to 50 million gallons a day
might reduce the price more.
"We finally have some facts
and numbers to deal with and not
work with estimates," said Don
Lindeman, manager of the desali-
nation project for West Coast.
Consultants for West Coast
had estimated the price of desali-
nation to be far higher, at $3 to
See WATER, Page 3 I

WATER/Proposals to be examined

I From Page 1
more than $4 per 1,000 gallons.
But those were estimates. No one
in the United States has built a
plant the size West Coast contem-
The price may make desalina-
tion competitive with other new
supplies of water besides well-
fields, said Gene Schiller of the
Southwest Florida Water Manage-
ment District.
During the next month, consul-
tants will examine the proposals to
make sure the corporate teams
can build the plant and check how
they will dispose of the salty by-
The consultants will rank the
proposals for West Coast's Jan. 26
The price also could be re-
duced if West Coast and Swiftmud
approve a deal that includes $40
million from Southwest Florida
Water Management District to de-
fray the construction cost of the
desalination plant. The district al-
ready plans to pay $50 million.
Before the plant is built, there
are other questions to answer. De-
s2lination produces a concentrat-

ed, salty brine that must be dis-
posed of and raises environmental
concerns. Most of the proposals
call for a plant on Tampa Bay
rather than the Gulf, something
that was not expected.
Energy use also could cause air
Here's a breakdown of the pro-
Progress Energy/lonics
Partnership proposes to build next
to the Florida Power Corp. power
plant on Old Tampa Bay. The 23-
million-gallon-a-day plant would
cost $72 million. Brine would
leave the plant through the power
plant's discharge canal. The water
price would be $1.54 per 1,000
Stone & Webster would
build at TECO's Big Bend site on
Hillsborough Bay. The 20-million-
gallon-a-day plant with another
4 million gallons spare capacity -
would cost $93 million. Brine
would leave through the power
plant's discharge canal. The water
price would be $2.18 per 1,000
Florida Seawater Desalina-
tion Co. proposes to build near the

Anclote River in either Pinellas or
Pasco counties. The 20-million-
gallon-a-day plant would cost $78
million. Brine would be released
into the discharge canal of the An-
clote River Power Plant The wa-
ter price would be $2 per 1,000
Enova/SuperSystems is-ne-
gotiating to use the TECO Big
Bend site. The 33-million-gallon-a-
day plant would cost $186 million.
Brine would be mixed with cooling
water and discharged through a
pipe. The water price would be
$3.98 per 1,000 gallons.
Florida Water Partners
would build at TECO's Big Bend
site. The 20-million-gallon-a-day
plant would cost $91 million.
Brine would be released through
the power plant discharge canal.
The water price would be $2.44
per 1,000 gallons.
