Carlsbad Desalination Project
The
Carlsbad Desalination Project, located in San Diego County, CA, at the
Encina Power Station, will provide 50 million gallons of desalinated
seawater per day. The privately financed project will produce enough
drinking water for 300,000 San Diegans annually and provide the County
with approximately 10 percent of its total water supply.
In August 2008, the facility secured the necessary state permits to proceed with construction and is slated to be operational in 2014.
The Carlsbad Desalination Project will have
significant economic benefits for the region, including an estimated
$350 million in local spending during construction, 2,100 jobs created during
construction and $50 million in annual spending throughout the region
once the desalination plant is operational. For the region, the
desalination facility will create jobs, generate tax revenue, improve
water quality and enhance water reliability with a new drought-proof
supply. Learn more at www.carlsbad-desal.com.
Huntington Beach Project
The Huntington Beach Desalination Facility in Orange County, Ca, is a 50-million gallon per day (50 MGD) project scheduled to be operational by 2015. The desalination plant will be located adjacent to the AES Power Station.
Poseidon Resources is in the final phase of the project’s permitting process and is currently working with state agencies to secure the remaining development permits. Learn more at www.hbfreshwater.com.
Treatment & Reclamation
Over the years, Poseidon has been a leader in the development of water treatment and reclamation projects. As world populations continue to grow, communities are left searching for innovative ways to get more clean water and, at the same time, effectively dispose of wastewater. Today, many communities are turning to wastewater treatment and reclamation. This process involves removing solids and other impurities from wastewater, then providing this treated water to industry or communities in lieu of potable water supplies. The treated wastewater is used in industrial processes, water cooling systems or for irrigation. This conserves potable water supplies, recharges underground aquifers and protects surface waters from nutrient loading.
Cadereyta Water Reclamation Facility
In October 1996, Poseidon Resources Corporation, through the
special purpose company Aquas Tratadas de Cadereyta, signed a contract
with the Petroleum Company of Mexico (PEMEX) to treat waste streams from
the refinery at Cadereyta, Mexico for reuse at the refinery. The
Reclamation Facility began full operation in October 1998, and it
provides 13.8 mgd. It consists of three trains for separate treatment of
municipal wastewater, refinery process waste flows, and cooling tower
blowdown and demineralizer regeneration streams. Treatment of the latter
streams consists of warm softening, filtration and desalination by
reverse osmosis, with the reject passing to evaporation and
crystallization to create a zero-discharge facility. The product from
desalination treatment is used for boiler feed water. The only waste
streams from the plant are sludge and salt crystals.
Madero Water Reclamation Facility
Poseidon
Resources Corporation, through the special purpose company Aquas
Tratadas de Madero, signed a contract with the PEMEX in
October 1997, to treat waste streams from the refinery at Madero,
Mexico for reuse at the refinery. The Reclamation Facility became fully
operational in November 1999. The facility has a total treatment
capacity of 3.5 MGD and consists of two treatment trains treating
refinery process waste flows, and cooling tower blowdown and
demineralizer regeneration streams. The latter streams are treated by
warm softening and filtration and combined with the treated process
water (having received biological and filtration treatment). The total
flow is then desalted using reverse osmosis, with the reject evaporated
and crystallized. The product from desalination treatment is used for
boiler feed water. The only waste streams from the plant are sludge and
salt crystals.
Minatitlan Water Reclamation Facility
In November 1999, the Petroleum Company of Mexico signed a
contract with Poseidon Resources Corporation, through the special
purpose company Aquas Tratadas de Minatitlan, to finance, design,
construct and operate a reclamation facility to treat waste streams from
the refinery at Minatitlan, Mexico for reuse at the refinery. The
Reclamation Facility has been operational since December 2001. The
treatment scheme consists of two trains: One for advanced biological
treatment of municipal wastewater and the second for biological
treatment of refinery process waste flows. With a combined total
capacity of 15.7 mgd, 9.1 mgd is further treated using ultrafiltration
(UF) membrane pretreatment system followed by reverse osmosis
desalination facility. The product from desalination treatment is used
for boiler feed water and other industrial process needs.
Salina Cruz Water Treatment Facility
The Salina Cruz water treatment facility is located in the state of Oaxaca, a moderately arid region within Mexico. Oaxaca receives most of its water during a winter rainy season and experiences water shortages during the drier summer months. To address the region’s water needs, our industrial customer Pemex, specified a multi-train water treatment and reuse system integrated with an ocean desalination system. The seawater desalination facility uses large intake beach wells, greensand filters and reverse osmosis membranes. The beach wells used at the Salina Cruz facility are the largest seawater intake wells in North America — three Raney-type radial collectors with capacity of 3.8 mgd, each. Since the fall of 2002, the facility has operated on a continuous basis and has a capacity utilization factor of over 95 percent.
Tula Wastewater Treatment Facility
The 5.5 mgd Tula wastewater treatment plant is located in the northern suburbs of Mexico City. The purpose of this plant is to produce effluent for water reuse in PEMEX’s Tula facility. The wastewater plant consists of primary treatment facilities, biological wastewater treatment and chemical filtration. Sludge from the biological treatment processes is disposed to a local landfill. The plant has been operational since October 2000, and its operational downtime is less than 2 percent — well within the contractual agreement.
Cranston, Rhode Island Wastewater Treatment Plant
Poseidon Resources Corporation, through its special purpose
company Triton Ocean State LLC, was selected by the city of Cranston,
RI, to make upgrades and improvements to the city’s wastewater treatment
plant and to operate the plant under a 25-year lease and water
treatment arrangement. Triton has completed over $30 million in
required upgrades and improvements to the 23 mgd treatment plant and
collection system since the contract began in September 1997.
Additionally, Poseidon made an upfront payment of $48 million,
which the city used to defuse existing debt, repay inter-government
obligations and provide a rate reduction for customers. Poseidon
provided equity, and the debt was financed on a non-recourse basis with
taxable institutional debt and tax-exempt revenue bonds.
