The Carbon Disclosure Project launches first water disclosure report on world’s largest companies

The report findings show that water is already impacting business operations with 96% of responding companies able to identify whether or not they are exposed to water risk and more than half of those reporting risks classifying them as current or near-term (1-5 years). 39% of companies are already experiencing detrimental impacts relating to water including disruption to operations from drought or flooding, declining water quality necessitating costly on-site pre-treatment, and increases in water prices, as well as fines and litigation relating to pollution incidents.

Water security is already high on the corporate agenda with 67% reporting responsibility for water-related issues at the board or executive committee level. The majority of companies (89%) have already developed specific water policies, strategies and plans, and 60% have set water-related performance targets.

After undergoing anywhere from three to 10 wash cycles in industrial-sized machines, the average pair of jeans uses 42 liters of water in the finishing process.

But by making simple changes to the jeans finishing process, Levi's has been able to dramatically reduce the water needed to produce each pair of jeans -- 28 percent on average, and as much as 96 percent in some jeans products.

i2O is a centralized water control method that directs the distribution and pressure of an entire water system. Sure, it sounds like Plumbing 2.0, but this is actually a good example of a disruptive technology.

i2O systems (that’s i two oh, not i twenty, if that wasn’t clear) have been installed in dozens of UK cities and save an average of nearly 50,000 liters a day each, as the system rerouted and adjusted pressure around leakages and inefficient pipes. There will still be bursts, and bad sealing, and we’ll still be losing a lot of water, but anything we can shave off the estimated 32 billion cubic meters of water lost from cities each year (World Bank estimate) is worth it.

In the early '90s, people thought Ed Begley, Jr. was eccentric...and not for the usual celebrity reasons. Instead, it was because the actor and environmentalist said one way to save water at home was using a bucket in your bathtub. (The man was ahead of his time.) With more interest in saving energy and water, the idea makes more sense now—in fact, try it yourself! Your hot water might take a minute or two to get from the hot water tank to your showerhead, depending on your plumbing configurations and home size. Use a one- or two-gallon bucket to collect the gush of initial lukewarm or cold water, and you'll be set for a warmer bath or shower and can save water for your plants or garden.

The Smart Grid has traditionally been used to describe the electrical grid 2.0.  The distinctions between the traditional electrical grid, or version 1.0, and the Smart Grid cover the bidirectional flow of electricity and communications.  We need to extend our thinking about the smart grid to add distributed intelligence and communications to other parts of the developed infrastructure – water and waste water, gas and oil pipelines, and even our transportation systems.  Doing so will help us engineer the most sustainable and cost-effective solutions.  

The relationship of electricity and water is particularly intertwined – it takes electricity to move and treat water, and water is quite often used to make electricity.  For instance, the state of California moves a great deal of water from the northern part of the state to the south.  Transporting one acre-foot of water – the typical amount consumed by two families of four in a year – requires 3000 kWh per year.  One acre-foot of water (the amount of water covering 1 acre to a depth of 1 foot) equals 326,000 gallons and weighs 2.7 million pounds. The California Energy Commission (CEC) figures that 20% of the state’s electricity and 30% of its natural gas consumption are dedicated to water transport or treatment.  A five minute faucet flow uses approximately the same energy as letting an incandescent 60-watt light bulb burn for 14 hours.

An experimental underground gas plant near Kingaroy in southern Queensland has been temporarily shut down after nearby water sources were contaminated.

Rural property owners within two kilometres of the coal gasification plant have been advised not to drink water from their bores.

The Department of Environment is investigating.

Bottled water distribution and solicitation of such services may soon be a thing of the past in San Francisco-sponsored events, if some city officials have their way. A meeting was held Monday, July 12 to discuss the issue, reported KGO-TV

If the bottled water industry continues to grow at the rate it has enjoyed the past decade, water fountains may become the new pay phones.  Walk through an airport concourse or public park and most water fountains stand unused.  Why would future new or retrofitted buildings include features, like water fountains that will only be ignored?  Cities that have perfectly fine drinking water, including Seoul and Amsterdam, have few drinking fountains in sight, and this could become true in American cities, too, if bottling companies have their way.

Millions of householders will face a hosepipe ban from Friday, a utility company has confirmed.
United Utilities, which supplies water to north-west England, said the measure will help "safeguard essential supplies".
Water levels in many reservoirs and lakes have plummeted to less than half their capacity due to the region's driest start to the year since 1929.

Each time drivers hit their breaks, or boaters put a new coat of paint on their vessel's hull, they're contributing to the level of copper found in the waterways, which becomes toxic to fish. From losing their ability to navigate to spawning grounds to losing their sense of smell, important fish species are affected by even the smallest amounts of copper in the water. That's why California is starting a crack down on copper pollution, including new laws and clean-up orders.
