Citing Jimmy Orth, executive director of the St Johns Riverkeeper, the newspaper notes that older washing machines can use around 40 gallons per wash and that for those forced to use such a machine, washing a full load is advisable.

"Purchasing a new washing machine ? will reduce water use by 35 per cent to 50 per cent ? Front-loading models use even less," the article quotes Mr Orth as saying.

It goes on to suggest using a shower with a "low-flow" head can make a difference and even newer toilets can also be more water efficient.

Earlier this month, HardwareZone reported that Sharp was to launch a new washing machine complete with new filter technology to reduce the amount of minerals in the water.
