Water Efficient Appliances ?

At a seminar on "Cost Effective Waste Water Management" organised yesterday on the occasion of the World Environment Day by the Institution of Engineers, I talked about our dying rivers* and the need for adopting water sensitive designs in our city planning.
If we have 'star rating' in electrical appliances, we can have ratings based on water use efficiency in appliances like Washing Machines, jacuzzi showers too.
But most important would be to usher in a mind-set that water must not be wasted or misused
