Egypt has developed a game-changing low-power water desalination technique

 Current desalination technology requires a high amount of energy, making it prohibitively expensive — especially in developing nations.

Californians on Insane Water Policy: ‘Whatever’

California residents have reacted to the state’s increasingly draconian water cutbacks with the well-known “whatever” spirit. They’ve significantly exceeded Gov. Jerry Brown’s water-conservation goals and tolerated rising water prices without taking to the streets in protest.

Australian sailing pressures Rio over water pollution

The water quality of Guanabara Bay, where Olympic sailing and other aquatic events will be held, has long been criticized and come under the microscope amid reports of athletes falling ill after competing there.

“It would be good if everyone in the sport kept the pressure onto the government to do what it really needs to do -- to tidy the place up," Conde said in comments published by News Ltd media on Sunday.

“We’re dealing with health and safety issues that are unusual for the sport to have to deal with."

Yuba City Water District fined over bacteria in wastewater

Yuba City Water Officials admit they were not in compliance with state standards for their water discharge, but they maintain their actions are not having any effect on the Feather River.

The Yuba City Utility Department was recently fined $12,000 after state tests showed the water treatment plant was putting out water that contained coliform levels that exceeded state standards.

In 2013, the plant received a $30,000 fine for other output violations, which officials say have now been addressed.

Safe Columbia water for all is days to weeks away, city official says Read more here

It will be days, even a couple of weeks, before all customers who depend on Columbia’s water system can rely on its safety for drinking and cooking, a key city staffer said Monday.

“Predominantly, if you’re in the city of Columbia, you still have to boil water,” said assistant city manager Missy Gentry.

The city’s flood-damaged downtown water treatment plant serves roughly half the water system’s 375,000 metro-Columbia customers.

In Columbia, a tale of 2 water plants from the man who probably knows them best

There are engineering and design reasons why Columbia’s two water treatment plants aren’t fully connected, and a solution to that shortcoming is on the drawing board, the city’s former director of the water system said.

“People say, ‘Why can’t we solely supply water from the Lake Murray plant to the (downtown) Columbia plant or vice versa,’ ” Bud Summers, who retired last month after 33 years with the city’s water supply system, including as its superintendent, said Saturday. “There’s not enough of the correct diameter pipes to move enough to sustain either plant.”

Columbia takes steps to ensure ample water supply

Columbia’s boil water advisory likely will be lifted sometime next week, city officials said Friday as water tankers with police escorts ferried more than 150,000 gallons of water to replenish the downtown water treatment plant’s permanent reservoir.

The plant has been operating under duress since Monday’s breach of the Columbia Canal dike. The canal feeds the plant and its 30 million-gallon-reservoir. Canal repair crews have been furiously trying to patch the dike damaged by floodwater while the city taps the reservoir and other water resources to keep the plant running.

Michigan providing water filters in Flint after high lead readings

The state last week confirmed a recent study at Hurley Children's Hospital that found increased lead levels in blood tests for children living in two Flint ZIP codes.

The city of about 100,000 residents started using the Flint River as its water source in 2014 after a state-appointed emergency manager ruled out a deal to keep buying water from Detroit, 66 miles (106 km) to the southeast.

Columbia can’t say when safe water will be restored

City employees are installing boulders as they work to repair a dike break at Columbia’s downtown canal and water plant, while others are trying to find all the breaks in water lines that feed the capital city and rural Lower Richland in the aftermath of historic floods.

At least 12 water line breaks have been identified, but, “We’re going to find a lot more than that,” assistant city manager Missy Gentry said Monday. City crews and private contractors are working on the dike and trying to isolate the number of breaks, she said.

Deep water: a new technology probes Sydney’s groundwater for the first time

 Here in Australia – the driest inhabited continent in the world – water is a particularly precious resource that we need to manage carefully.

Yet mining and other subsurface engineering projects have the potential to impact groundwater. In the Sydney Basin region, underground coal mines operate near surface water reservoirs that are important for Sydney’s water supply. In other regions, coal seam gas extraction is being managed to minimise risk to adjacent aquifers.
