Hello Alana,
From the retention ponds to the storage tanks, it’s a combination of pump and gravity fed network of HDPE pipes.
This network is basic (as you can observe in the gallery under Design Area Two). Flow control and maintenance is mostly manual, with ongoing upkeep and operation by the GMF (volunteer Water User Group). Some storage tanks are fitted with solar powered water level indicators and automation, however these are limited.
Cheers,
Anthony
