Why save water?  And how?

Water is still cheap: there aren’t many products that you can have delivered to your door for just over $2/kL, or $2/m3. It’s what you do with water that costs money – it’s pumped, heated and treated.

Good water management is a combination of the three  3M’s: Metering, Monitoring and Maintenance. And there are significant savings that can be made by simple practices.  A recent study into 24 Sydney business hotels showed that from 2006 to 2010, Sydney hotels had improved water efficiency by reducing leaks from an average of 30% to 8%, and five hotels had zero leakage: a significant reduction.

Once this is underway you can improve water efficiency by using the three  3R’s – Retrofitting, Reuse  and Recycling.

The same study showed that the hotels in the study had improved water efficiency by installing low flow taps and shower fittings in guest room bathrooms. In combination with better maintenance practices, this allowed the average hotel to reduce water consumption by an average of 241 L/guest/night or over 40%. A significant saving: on a large hotel with 400 guests this water efficiency would equate to saving over $120,000 a year on the water bill alone.
