Save rainwater

With winter approaching, now is the time to think about installing a rainwater tank to reduce your home's reliance on Perth's precious scheme water.

WHY RAINWATER?
According to Andrew Waudby, of Waterplex, a rainwater tank is a great one-off investment to make a difference to the environment and reduce your annual household water costs.

"The average rainfall for Perth is approximately 800mm per annum. 1mm of rain on 1sqm of roof gives one litre of stored water, so 1sqm of roof gives 800 litres per year. So a 100sqm roof gives 80,000 litres."

He said Perth homeowners had the ability to make a great difference to the local water supply simply by installing a tank.

A 2500-litre tank would provide sufficient water storage for the average household during winter.

"People think they need a big tank to get them through the summer but that's not the case," Mr Holmes said. "During the winter time, you are catching water from your roof and if it's operating your toilets and laundry with savings of up to 46,000 litres of water a year".

I was stunned to learn that the average household in Perth uses 734 liters of water per day!

Don't forget to turn of your reticulation, as from 1 June there is a sprinkler ban.

Higher tax call for McMansion dwellers

PEOPLE who want to build energy-guzzling McMansion-style homes should pay more taxes.
And taxes should also be used to make owning multiple plasma TVs prohibitive, says Melbourne University construction expert Dr Robert Crawford.

Rapidly increasing suburban house sizes, more reliance on cars and a rise in demand for consumer goods had wiped out many of the benefits of building energy-efficient homes, he said yesterday.

"The most dominant characteristic of the new houses in these estates is their size ... new residences are well over 200sq m, more than double the average of the 1950s," he said.

World's carbon emissions hit record rise

Carbon emissions in the earth's atmosphere have reached a record high, according to the International Energy Agency.

Scientists warn that climate change will lead to unprecedented catastrophic consequences, if global leaders do not take decisive action to reduce the harmful emissions soon.
And all they do here in Australia is talking about how Cate Blanchett should or shouldn't be in the picture for this... sad...

Smugglers sneaking e-waste out of Australia

Australia has been accused of breaking its international obligations by not doing more to stop electronic waste being smuggled out of the country.

The ABC has learned that four shipments of illegal e-waste - including discarded computers, mobile phones, televisions and other devices which contain deadly chemicals - have been intercepted so far this year.

But details about the seizures are sketchy.

Australia is starting to groan under the weight of a growing mountain of electronic waste. The discarded devices often end up in landfill with all the environmental concerns that generates.

Enforcing legislation
So far calls to several government agencies, including Customs, have failed to answer any detailed questions about the seizures and whether or not anyone was charged for smuggling.

The responsible parliamentary secretary, Don Farrell, has also been unavailable for comment.

Mr Walker says much of the rest ends up in landfill.

"I think the current figure is about 40 million computers have gone into landfill here in Australia alone," he said.

"But around 60 per cent say of the computers that are collected through recycling schemes end up going overseas".

5 June - National Day of Climate Action

From the GetUp team:

So far, 3,440 people have RSVP'd to family climate rallies across Australia next weekend. But I just finished reading the Australian Climate Commission's new climate science report - and frankly, I'm scared. The risks have never been more clear and the case for action has never been more urgent. Scientists know this, you and I know this, but the rest of Australia still needs to hear it.

The Government and Independents on the committee are under extraordinary pressure to give up on climate action. Climate deniers held a rally against the carbon price last week in the electorate of Independent MP Rob Oakeshott. The Daily Telegraph reported that over 3,000 people attended - even though the official police estimate was under 800. Right now, politicians and the media are gauging support for climate action by which side has the bigger rallies.

Some say putting a price on pollution will send our economy back to the Stone Age. They say they represent the majority of mainstream Australia. We know it's rubbish - but unless we put our faces and voices in front of the TV cameras too, we know exactly what will happen next: an exasperating onslaught of one-sided media coverage against climate action, which will send politicians running scared.

If Australia's climate policy were decided by science and reason, we would have put a price on pollution long ago.

Please join the urgent climate rallies happening across Australia on Sunday week, June 5, and don't forget to bring a friend, or ten!

WA dams set to dry up by summer's end, expert warns

Perth's drinking water supplies from dams will run out by the end of next summer even with decent rainfall, according to predictions by the Centre for Water Research.

By then, Perth and the South-West would become solely reliant on water supplied from the already stressed Gnangara Mound aquifer and the Kwinana desalination plant, director Jorg Imberger said.

Even using an optimistic calculation that 35 gigalitres (35 billion litres) of rainwater would flow into the city's dams - far greater than the 13 gigalitres last year - the dams would run dry.

"(Even) given recycled water, less water use, pumping the surface aquifer at Gnangara Mound a little bit more and hoping for rain, we'll basically have no water left at the end of summer 2012," Professor Imberger said.

Update 30 May: No need to be squeamish
There has been predictable squeamishness about the news that the Water Corporation has been asked to fast-track its Groundwater Replenishment Trial, ramping it up far beyond the current rate of 5 million litres treated and injected into the ground each day.

Since it launched last November, the trial has pumped 544.5 million litres of treated water into the Gnangara Mound, which provides 90 per cent of Perth's groundwater, via an injection well at the corporation's Beenyup water treatment site.

Ask a Londoner about water recycling and they'll tell you it's a simple fact of life, even though they will probably complain about the rain in their next breath.

The fact is that Perth and the South West are in trouble, despite the impressive response to the Water Corporation's challenge to Perth households to save 60 litres per day over the past few months.

Currently, Perth dumps 300 million litres of wastewater a day into the Indian Ocean - much of it after extensive treatment. Instead of throwing that water away, groundwater replenishment would see large amounts of that water rescued, treated to a higher standard and then used to preserve our aquifers.

Fund Solutions Not Pollution

Solidworks Green Design Contest

The Challenge
Imagine that wealthy entrepreneur "Sir Richard Doylson" has decided to launch a new airline powered solely by algae-derived biofuels, called Greenair. Your firm, SWUGN Enterprises, has been charged with designing new “green” airport terminals for Greenair, and (of course), terminals need chairs. It’s up to you to design a chair worthy of the Greenair name, and Sir Richard’s execs will be judging your work.

Good constraints lead to inspired design, and as Earth Day reminds us, our planet provides the ultimate constraints—it can only support so much resource consumption and waste emissions. We invite you to design a new chair that’s both aesthetically appealing and fully functional, while maintaining a small environmental footprint. To do this, you can either download the starter model – a rather plain-looking, industrial affair – and modify it, or design a completely new chair yourself.

Thong Nation: Throwaway Footwear Now Taking on a Greener ‘Sole’

Flip-flops, usually made of polyurethane, are the focus of both recycling and upcycling efforts this spring.

The moment our old friend Mr. Sunshine makes his presence known, socks and lace-up shoes are typically pushed aside in favor of those perennially toe-baring delights known as flip-flops, and boy, what a relief they are. Bestowing the wearer with an instant form of eco-friendly air conditioning during seasonal heat waves — often for as little as one solitary dollar per pair — the rubber-soled wonders seem innocuous enough, but Mother Nature would likely disagree.

Here’s the first problem. Today’s models are commonly made with crude oil-based polyurethane (aka #7 plastic) rather than sustainably produced natural latex rubber, and are almost always excluded from municipal recycling programs.

They are also so impossibly affordable and manufactured in a rainbow of alluring colors and patterns that consumers can easily justify owning a dozen or more pairs, which ends up fueling hyper-consumerism. Rather than spending the time to repair or even creatively upcycle a flip that has met its final flop, we typically chuck and replace what is no longer up to snuff since there’s always an infinite, budget-worthy supply at our fingertips.

Axe falls on heritage centre, school

FOR 16 years, Dwellingup has been associated with beautiful woodwork from the Dwellingup Forest Heritage Centre and Australian School of Fine Wood – and many residents are angry about the abrupt closure of the centre last week.

Senior lecturer Malcolm Harris said although he had heard about financial issues a few months ago, there was no warning last Monday when “the axe fell”.

“We had just started class when members of the board and Peel Development Commission informed us the centre was closing as of that moment,” he said.

Mr Harris said most of the eight students and four staff members were in shock.

Great Sustainable Home Challenge: Part 2

WA has some of the worst soils in the world. Sandy, dry, devoid of nutrients - it's a wonder we can grow anything at all.

But living in a virtual desert shouldn't stop you boosting your home's sustainability by growing your own food. All you need is to give your garden a bit of TLC, and your veggies will be ready for harvest before you know it.

"Contrary to what you may think, it's actually really easy to produce a productive, healthy and sustainable garden, using a lot less water," said green guru Chris Ferreira.

As part of his Great Sustainable Home Challenge, in which he will transform his 1950s Hamilton Hill house into a bastion of green living, Chris enlisted the help of horticulturalist Peter Coppin to sort out the soil.
