Consolidated Water (CWCO) to Build Desalination Unit in Cayman – Cayman Island – North America

CWCO announced that it signed a definitive agreement with the water authority of the Cayman Islands for a seawater reverse osmosis plant in George Town, Grand Cayman.

The plant will produce up to 2.64 million gallons of potable water per day using two independent reverse osmosis trains.

Consolidated Water expects the deal to generate $20 million in revenues over the term of the contract of nearly 11.5 years, with the majority of revenues expected in the first 18 months as the company builds and sells the plant to the water authority.


After Five Weeks Without Water, Comcaac Community In Sonora Seeks Urgent Help – Mexico

Members of an Indigenous community in neighboring Sonora, Mexico, say they are experiencing a critical water shortage after weeks without reliable access.

Water scarcity is a long-standing and constant issue in Punta Chueca — one of two Comcaac towns on the Sea of Cortez. But the community has now gone five weeks without water from the town’s failing desalination plant.

Water trucks sent by the government or paid for by the community are insufficient and some families lack large drums needed to store water between deliveries, leaving many without water for drinking, bathing and cleaning.


Mexico modifies 2 PPP water contracts for Baja California Sur – Mexico

Mexico’s Baja California Sur state has modified the tender calendars for two public-private partnership contracts, worth an estimated 5.2bn pesos (US$252mn), that will be awarded this year.

The projects concern the 3.9bn-peso, Los Cabos desalination plant and the 1.3bn-peso integral improvement of Cabo San Lucas city’s water distribution system. 

The contracts for both projects were expected to be awarded on March 17 and 18, respectively, but a notification on procurement site Compranet late last week said the dates were changed.


Residents face water woes in central and south; WASA responds – Caribbean

The Water and Sewage Authority (WASA) is assuring customers in parts of Central Trinidad and in particular the Claxton Bay and Couva areas, who have been experiencing a disruption in their normal water supply that, every effort is being made to remedy this situation.

WASA said these areas are serviced from the Authority’s Caroni Water Treatment Plant (WTP) and the Point Lisas Desalination Plant.

However, it indicated there have been periodic disruptions at both facilities in recent weeks that have impacted the reliability of supply to these and other areas.


Where’s the Water? – Mexico

I love San Miguel de Allende.  It’s a lovely town in Mexico, and anyone who wants romance in his or her life should come down here.  It’s  just turning June, and it’s starting to get hot from Sarasota to Dallas to Los Angeles, but not here. 

No, this is supposed to be the rainy season.  And May was supposed to be hot, but it wasn’t.  Yes, this would be a Mexican paradise, except for one thing.

We’re running out of water.  We had less than an hour of rain yesterday.  They keep predicting rain but it doesn’t come.  Meanwhile, the aquifer drops lower and lower each year.  And because it drops, the natural underground chemicals (arsenic and fluoride)  become a great part of what comes into our cups.


Rethinking Wastewater Treatment for Better FGD Economics

Since its introduction in the 1960s, electrodialysis (ED) technology has been adopted for a wide range of industrial applications, and today it is the second-most widely used membrane desalination technology.

The traditional technology involves applying a direct-current electric field to flux positive ions across cation exchange membranes in one direction, and negative ions through anion exchange membranes in the opposite direction.

More recently, it has benefited from an innovation that helps to keep the membranes cleaner by allowing the polarity of electrodes and hydraulic channels to “reverse.”


Drag the nation’s water systems into the 21st century, Minister Charles Jr – Jamaica

When Senator Pearnel Charles Jr was assigned the water portfolio I held my breath and waited for good news. He is an attorney by profession, but let’s not hold that against him. I see him as one of the Renaissance men in this Administration, and fully expected him to drag this sorry department scratching and kicking into the 21st century.

Jamaica has an abundance of hydrologic resources. There should be more than enough to meet local demand. The first problem is that it does not always rain where we want it to and when we want it to. Then, like rice, sugar cane and bananas are thirsty plants, and our immigration strategies are woefully inefficient.

We are heavily dependent on ground water, an increasing amount of which is being contaminated by the bauxite-alumina industry. When we hear of deforestation, everybody’s minds run to coal-burning and the clearing of land; nobody talks of the harvesting of yam sticks and its impact on deforestation. But a 2003 study by Barker and Beckford revealed that some 63 million yam sticks are harvested each year. This has a huge impact on the maintenance of forests. The sticks used for fish pots have never been quantified.


More water woes as Desalcott goes down again – Caribbean

The Water and Sewerage Authority is advising customers in parts of Central and South West Trinidad, served by the Point Lisas Desalination Plant, of an unplanned shutdown at the facility on Friday.

This was due to a leak that has developed on the fiberglass clearwell system at the Plant that will require emergency repairs.

The owner and operator of the Plant, the Desalination Company of Trinidad and Tobago (DESALCOTT), is currently in the process of assessing the full extent of the damage, after-which an estimated timeframe will be given for the completion necessary repair works.


Mexican Region Gets First Desalination Plant for Agriculture Use in the Americas – Mexico

Weather conditions in San Q1uintin, a region in the northwestern Mexican state of Baja California, are good for growing crops year-round, but the lack of water in the area is forcing farmers to turn to innovative and environmentally friendly technologies, such as desalination, to deal with the problem.

The drought that affected San Quintin from 1985 to 2015 caused the amount of land under cultivation to fall from 28,000 hectares (69,135 acres) to 7,889 hectares (19,479 acres), a reduction of 72 percent.

A company called Grupo BerryMex recently announced that it was going to start operating the first agricultural desalination plant of its kind in the Americas in San Quintin, allowing fields to be irrigated.


Rising sea threatens South Florida’s drinking water and region’s economy – Florida

You grab the last box, freshly packed with life’s memories. As you drive toward the highway, you pass the ruins of what used to be the city you made a home.

The downtown is now a ghost town. Your company has laid you off because all the offices are being forced to close. You must leave the city that you love. Why? The city that floods almost every day no longer has fresh drinking water.

Unfortunately, this scenario might become a reality for most of South Florida’s residents, who receives their drinking water from one source, the Biscayne Aquifer. The aquifer serves residents in Miami-Dade, Monroe, Broward and Palm Beach counties.
