Hunter Water will start dipping into supplies from the Tomago Sandbeds, following a steady decline in the region's overall water stores.
Overall water storages are down by more than 20 per cent since last November, leaving levels at 63.7 per cent capacity, which is just above the 60 per cent trigger for Stage One water restrictions.
Stage one restrictions include reducing daytime outdoor watering and the use of trigger nozzles, along with advice to customers to implement their own measures such as fixing leaking taps and toilets, waiting for a full laundry load and aiming for no more than a four minute shower.
With the long-term weather outlook predicting warmer and drier conditions associated with an increased chance of an El Nino event, Hunter Water has decided to begin supplying drinking water from the Tomago Sandbeds.
Hunter Water executive manager Glen Robertson said the Sandbeds play a significant role in the region's water supply system, providing up to 20 per cent of drinking water during times of shortfall.
He said there may be temporary changes in water taste and colour for some customers but the water remains safe to drink after having been tested at multiple points before entering the drinking water network.
"Groundwater contains higher levels of naturally occurring minerals such as iron and manganese and these minerals can be more difficult to remove during treatment and may occasionally cause some discolouration, which is not a health concerns," Mr Robinson explained.
In addition to increasing supply through the Sandbeds other initiatives being deployed include working with businesses and communities around ways to save water, and ensuring all water storages remain available to address prolonged periods without rain.
There is also work underway on a desalination plant, although that won't be available until 2028.
In the meantime, Hunter Water said the additional supply from the Sandbeds, along with smart water choices by consumers, can delay the need for any water restrictions.
It is currently forecasting the 60 per cent threshold for stage one restrictions to be reached in mid to late June.
