Sydney, Australia’s Barangaroo South – a net positive water project
Water is a hot topic. With water tables dropping around the world, lakes and rivers are drying up. Annual rainfalls are changing, often dramatically. As temperatures around the globe heat up, drought is becoming the new normal. So builders and architects are turning their creative minds to innovation to recycle and reclaim water in order to turn once waterhog-ish buildings into net positive ones.
A recent article highlights a new urban renewal project in Sydney, Australia, that focuses on just this.

Editor: The following is an excerpt of an article by Rowan Jacobsen. It offers an intriguing idea and opportunity that not only could help bring water to countries (and villages) parched by continuing drought but also help resolve conflicts between warring nations.
Scientists and others look to desalination as a way to unite longtime enemies in a common cause.
Israel’s Sorek Desalination Plant – an opportunity for water and easing conflicts
July 19, 2016 — Ten miles south of Tel Aviv, I stand on a catwalk over two concrete reservoirs the size of football fields and watch water pour into them from a massive pipe emerging from the sand. The pipe is so large I could walk through it standing upright, were it not full of Mediterranean seawater pumped from an intake a mile offshore.
“Now, that’s a pump!” Edo Bar-Zeev shouts to me over the din of the motors, grinning with undisguised awe at the scene before us. The reservoirs beneath us contain several feet of sand through which the seawater filters before making its way to a vast metal hangar, where it is transformed into enough drinking water to supply 1.5 million people.

If you think that slow leak or drip doesn’t add up, think again. A report revealed that Americans waste 2.1 trillion (with a T) gallons of water each year due to old and leaky infrastructure such as aging and leaky pipes, broken water mains and faulty meters.
Listen to this segment from NPR. Then maybe it’s really time – and cost-effective – for cities and residents to invest those funds to repair and replace those old pipes before more of our growingly scarce water gets wasted.

Plastic microbeads – tiny, toxic, plastic beads – are in many of our personal care products, like face scrub and toothpaste. They’re so tiny that they are washing down the drains and into our precious waterways.

If you’ve flown into or out of the Sacramento airport, looking down you’ll see a lush river area meandering through acres of rice fields. That’s part of the Sacramento-San Joaquin River Delta, the biggest estuary in the West Coast of North America and the focal point of the new documentary “Over Troubled Waters”.
The film, which debuted on August 9th, chronicles the complex issues surrounding California’s tug-of-war struggle for water between the north and south state.
To find out more about this remarkable film and the history and issues surrounding the Delta, go to http://bit.ly/Rl1QrD.

On Wednesday, California Governor Jerry Brown and Interior Secretary Ken Salazar announced what they consider a landmark solution to the state’s water shortage: plans to build a massive twin tunnel system that will bring precious water from the San Joaquin River Delta to farms and cities. These two 33-mile-long tunnels have stirred the pot of an ongoing water war. This controversy is at the heart of a new documentary, Over Troubled Waters.
To understand the issues and some surprising history that’s been concealed, and have a chance to win tickets to the Sacramento premier of Over Troubled Waters, see http://bit.ly/NyVftn.

Aqua Cents – a remarkable innovation that dramatically cuts lawn water waste and use
Landscape irrigation accounts for almost one-third of all residential water use, totaling more than 7 billion gallons per day in the United States. Almost 50 percent of that is wasted– both commercially and residentially– due to evaporation, wind, improper system design, or overwatering.
With many cities facing severe water shortages and a drought spreading throughout the Southwest, lawns are squandering a precious resource we cannot afford to lose. More cities across the country are installing water meters, and California has mandated that these be installed in all cities by the year 2025.
But saving water requires more than metering. It means rethinking how we water our plants, and developing new best practices that will help us create substantial water savings.
Aqua Cents is an extraordinary technology that could help us with both.
