Blog Action Day 2010 - Water: how design can help?

Blog Action Day 2010: Water from Blog Action Day on Vimeo.
Water is precious. And we have to show we are aware of this every time we use water - this means all the time! 
Blog Action Day is an annual event held every October 15 that unites the world’s bloggers in posting about the same issue on the same day with the aim of sparking a global discussion and driving collective action. This year's topic is water.
How can design help saving water? In many ways - with every object we use. I recently published a post about domestic ponds as a beautiful way of re-using water. 
And especially in places like bathroom designers have concentrated their efforts to create modern living environment with the least water waste possible. Here are several examples:

• a modern design  of a new faucet Fiji  wich allows us to consume 40% less water;
• 5 Beautiful Shower Designs That Actually Save Water;

• W+W – GROUND BREAKING DESIGN FROM ROC. Here below is the information from Roca: 

"Created by the Roca Innovation Lab together with the designers Gabriele and Oscar Buratti, W+W is a truly exciting new product revelation from Roca.
The washbasin and WC are two essential elements in every single bathroom. Highlighting its commitment to design and innovation, Roca has combined these two elements to create W+W – an all-in-one washbasin and WC made from vitreous china, designed to maximise space and conserve water. This ground breaking idea, incorporating Roca’s new ‘water-reuse’ technology, uses waste water from the basin to fill the WC cistern, thereby reducing water usage by up to 25% compared to a standard 6/3 litre dual-flush WC.

The basin in W+W has two wastes – the basin waste and one further down the waste pipe. Once the basin has been used and filled with water, the user has the option of either diverting it to the mains (e.g. if the basin is being used for shaving, or brushing teeth), or recycling it by storing it in the cistern ready for the next flush."

One important project that includes many cheap solutions for saving water is Design for the Other 90%
like this Drip Irrigation System:The kits are significantly less expensive than conventional drip systems used on commercial farms. Studies show that drip irrigation reduces water use by 30-70% and increases yields by over 50%.
