How’s this for a low impact bath. My kids recently had a bath in my brother’s backyard.

The bath was found lying around my brother’s property – he previously used it as a worm farm.

The water was collected in a tank and the heating came from burning reclaimed wood (see the ashes under the bath).  The air conditioning and heating – well that was provided by Mother Nature.

As the hot summer months approach it’s important to ensure gardens are in excellent shape waterwise.

Here’s a little article I wrote for G magazine a while back. Just saw it online.

The Alternative Technology Association (ATA) also recently released an excellent book about conserving water around the home.

The book, Water not down the drain, tells you about:

• Choosing rainwater tanks and harvesting rainwater
• Supplying rainwater to the house and garden
• Setting up a grey water diversion system
• Grey water treatment systems
• Grey water health and environmental concerns
• Creating a rain garden to capture storm water
• Cutting greenhouse emissions while saving water

Last weekend my family and I visited some interesting places during Sustainable House Day. This year there were so many houses on offer, it was difficult to choose which ones to visit — our time was a bit limited because we had a four year old and a small baby with us.

We chose the Hawkesbury EarthCare Centre, an owner-builder house constructed from interlocking concrete blocks and a new house using many clever environmental elements.

I’m really looking forward to next weekend because it’s Sustainable House Day (September 13-14). Finally, I’m going to be in Sydney to enjoy some houses in my area – and this year there seems like quite a lot.

A few years back I was in Canberra so I checked out a few houses there. The one thing that amazed me with the houses there was how cold it was outside, but how toasty warm (with no heating) it was inside due to solar passive designs and thermal mass. The houses also gave me some good ideas of what I could do in my own house.

The event is happening across Australia and New Zealand so check out some houses in your area for some good ideas and inspiration.

If you do, please tell us about the places you visited in the comments section below.

I’ve just finished reading Making Your Home Sustainable by Derek Wrigley. It’s a really useful book for anyone wanting to retrofit their house to improve its energy and water efficiency.

When architect and solar consultant Derek Wrigley moved into a townhouse in Canberra in 1991, he began retrofitting it to reduce its dependence on fossil fuels. Throughout the book, Wrigley uses the house to show how homes in Australia’s southern states can be made more sustainable.

The book is ideal for home owners who can fit out and alter their house. However, there is a small and informative section that provides renters with ways to improve their home’s efficiency at minimum cost.

The book covers more than just basic green living tips – it provides detailed information (but easy-to-understand) about solar energy, energy efficiency, appliances, mass and thermal comfort, insulation, ventilation, minimising water and effective landscape use.

It’s a great resource for all us retrofitters out there. To buy the book, visit Scribe Publications.

I hope all you mothers out there had a great Mother’s Day. I started my morning with pancakes and coffee – thanks to my husband and son.

The rest of the morning was spent with my feet up watching my Mother’s Day present – the Gardening Australia DVD on waterwise gardening.

It’s a collection of segments from the show that feature saving water in the garden. If you’re a Gardening Australia fan like me, and into saving water, then you’ll love this DVD.

It shows how you can still have a great garden but without the need for loads of water. The DVD features some great waterwise gardens in Australia, useful tips on drought proofing plus which plants look great in the garden but need little water.

A great 92 minutes worth of entertainment, and an excellent way to start Mother’s Day.

Finally, there is a water tank that you can pack up and take with you when you move. If you don’t want to create your own do-it-yourself tank or fork out for the more expensive metal or plastic tanks, which remain as permanent fixtures to your home, then possibly the Handytank could be for you.

The Handytank is a 1,000 litre water tank which can be bought at Kmart, Mitre 10, Home Timber and Hardware, Thrifty-Link and Trade Link stores. It comes in a flat pack so can be transported home in most cars and is assembled and fitted in about 20 minutes. The manufacturers also claim it can be easily dissembled for easy moving.

I love the idea of a water tank that you can take with you when you move, such a great idea for people renting. Now if you could just do the same with solar panels…

Aquaponics is one thing I haven’t thought about venturing into. I always thought setting up an aquaponics system looked too labour intensive, and it needed a lot of water. Plus I love the smell and touch of soil, and all the little critters that good, healthy dirt brings.

However, through Greenfoot I have been in contact with a few people who run their own backyard aquaponics systems and, once set up, they assure me aquaponics is less labour intensive and uses very little extra water.

It’s also the symbiotic nature of such a system that I find quite fascinating. (more…)

The Australian Rainwater Industry Development group (ARID) has released its 2008 Rainwater guide. It provides information and tips about rainwater products, government rebates and regulations for new homes.

You can buy the guide in selected news agencies around Australia or download it from ARID’s website. It will also be available in the March issue of Better Homes and Gardens magazine.

Welcome back to 2008. I hope you all had a good break over the Christmas/New Year period. So far this year (and the last few months of 2007) has been great for our garden. Sydney has had so much rain.

My garden is thriving. Our space saver pumpkins have taken off as well as my cherry tomatoes, rhubarb, rocket, herbs, jalapeno peppers, sunflowers, carrots and leeks. My fruit trees are also looking pretty good - mandarin, lime, lemon, bush lime, fig, mango, olive, avocado, mulberry and guava. Although my chocolate sapote got an attack of black soot and never quite recovered.

The rain has also been extra kind to our lawn. I know lawns get a bad rap these days but we put a small patch in during spring. It replaced a very weedy section of our garden and some broken pavers. Originally we wanted to grow a native grass but couldn’t find one that resembled a tough lawn that could deal with a lot of wear and tear.

We chose Sir Walter, which claims to be a hardy, shade and sun tolerant variety of grass, as well as being very water wise. The excessive amounts of rain means that the grass is now well established and thriving, without us having to use the hose. Although, sometimes I put the grey water run off from our washing machine on to the lawn.

Although I would have loved to turn the lawned area into vegetable patches, we decided to lawn it for our son. He really needed somewhere to play outside and the lawn has really done the trick. No more scraped knees on the pavement as he slides down his slippery slide ;-0.

The other thing I love about the lawn is the constant supply of mulch I have. I thin layer of grass clippings over the garden beds really helps suppress weeds plus reduce water evaporation from the soil. I don’t have to buy sugar cane mulch anymore. The clippings also heat up quickly in my compost bins, which helps everything to quickly break down.
