That's water efficiency.Loss of nutrients through wastewater into rivers or oceans is significant form of pollution .Book now before the prices go up!When this is full, a float switch detects it and the water is automatically pumped to a 1000 litre (200 gallon) tank above ground.Look after your water, and it will look after you.The wind isn't extreme all the time of course, but it happens enough to be a worry - unfortunately hot weather causes hot air to rise and cooler air rushes in to replace it - wind.
Water efficiency - just what is all this 'water stuff' all about?
