The Burren Junction Bore Bath was first sunk in 1921. Water ran from the bore into a series of bore drains (ditches) which distributed the water around the district for various agricultural and domestic uses.
The water found in bore baths such as Burren Junction, Walgett and Lightning Ridge comes from the Great Artesian Basin and is approximately two million years old. Bore depth is logged at 689.8m (226ft) and natural pressure sends the water to the surface through an artesian bore and it maintains a constant temperature of approx 41.5 degrees Celsius.
The Great Artesian Basin is one of the world's largest freshwater basins in the world; it contains approximately 8,700 million mega litres of water and underlies 22% of Australia and 26% of New South Wales. The Basin supports 200,000 people and underpins $3.5 billion of production annually.
The water now runs into the pool from the bore and then out into the holding ponds where it evaporates into the air. If the evaporation ponds fill up the bore flow must be turned off until the water level goes down. Water originally flowed continuously at 20 litres/second, 450 million litres was wasted annually. Water flow has been reduced saving 11 litres per second.
The bores supply these baths are only a few of hundreds being rehabilitated; replacing bore drains with underground pipes.
