A Sustainable Life: Cool Clear Water

BIG WET: Daylesford has experienced some of its best winter rainfall in years, but residents cannot afford to become complacent when it comes to sustainability.How’s this rain!We haven’t had a winter like this for along time, but don’t be lulled into a false sense of security.

I’ve been doing some work at Melbourne Water, so I’ve become a bit obsessed with storage levels.

I have to say, I was pretty surprised when I discovered Melbourne’s reserves were at 63.53 per centand central highlands is at 59.10 per centat the time of writing.

We always seem to have abundant levels of water, this area being so lush and green. Even in the harshest times, it seems not as dry as other places – proof again that perception doesn’t always equal reality.

You’d expect that the water reserves would be much higher with the rainfall we’ve received. Since investigating further, I’ve learnt that the ground acts like a sponge and will soak up water before it starts filling the reservoirs.

You can test this theory with a dishwashing sponge –that’s how it was explained to me in the kitchen at work. When you pour water onto a sponge, it absorbs a certain amount before it starts spilling out. We’ve had little rainfall over an extended period of time and as a result the ground has become incredibly dry, so it has to get to a certain moisture retention level before the reservoirs will start filling.

We also have the challenge of our population increasingon weekendswith our healthy tourist industry, sowater captured in our reservoirs is used as demand grows.

All this got me thinking about how much water is required to produce food we consume. I discovered a great site available through National Geographic that lists a range of products and the amount of water required to grow or make them.Here are some popular consumables:

Beef (0.5kg),6810 litresChicken (0.5kg),1773 litresLamb (0.5kg),2769 litresEgg (one),200 litresApple (one),70 litresOrange (one).50 litresWheat (0.5kg), 500 litresBread (one slice), 40 litresCheese (0.5kg), 2273 litresMilk (3.8 litres), 3331 litresCoffee (3.8 litres),3331 litresTea (3.8 litres),484 litresBeer (3.8 litres),2608 litresWine (3.8 litres),3816 litresChocolate (0.5kg)12,000 litresIf you were trying to give up chocolate, there’s another good reason!

All of this puts the persistence of this rain into perspective. It’s really important to not take water for granted, no matter how much is fallingat the moment.

I recently visited Sugarloaf Reservoir near the Christmas Hills east of Melbourne. It’s one of fivecatchments that supply Melbourne with water. When full, it holds 96,253 megalitres of water.

This was put into context when someoneexplained that if this catchment wasn’t continually topped up,and it was the only reservoir used to supply Melbourne, it would last threemonths before running out.

Our Wombat Reservoir might appear to be overflowing at the moment,but it’s really important that we continue to conserve this precious resource.We can do this by:

Following water restrictionsInstalling a water tankBuying water efficient appliancesInstalling a water-efficient showerheadInstalling a grey water systemInstalling a dual flush toiletPlantinga drought-tolerant garden and use mulch to hold moisture in the soilWe can also make a difference by changing habits. This can includetaking shorter showers; turningthe tap off whilebrushingteeth; usinga plug to fill the sink when washing vegetables or dishes by hand; and making sure dishwashing and washing machines have full loads.

The rain will stop soon. Let’s hold onto the water we’ve been granted, because we don’t know when it will be back again.
