All water supplied via the Gascoyne irrigation pipeline is raw untreated non-potable water and is supplied for the irrigation of crops and watering of stock and garden only.
The water fed into the scheme is sourced from two borefields the Northern borefield (owned by GWAMCO and operated by GWC) on the northern bank of the Gascoyne River
and the Southern Borefield (managed by Water Corporation) on the Southern side of the river.
As part of its licence requirements GWC samples annually all the production bores in the Northern borefield and obtains NATA accredited analysis results on the water produced from this borefield. Water Corporation also tests the raw water produced from the Southern borefield reports of which GWC receive from time to time when requested.
