Hunter Water is calling on Lower Hunter residents to use four less buckets of water than usual each day as the region braces for water restrictions next week.
The Hunter's storage dams are currently at their lowest levels in more than two decades due to the severe drought affecting NSW.
The amount of water we use in our homes has a significant impact on our storages, Hunter Water said.
"Saving four buckets of water is all it takes to make a difference," said Hunter Water's executive drought lead Darren Cleary.
"While Level 1 water restrictions will focus on reducing outdoor water use from next Monday, there are plenty of simple and easy things we can do every day that will save our precious resource.
"On average, Hunter Water customers use approximately 190 litres of water per person each day, which is about 10 to 20 per cent more when compared to other areas like the Central Coast, Melbourne and south east Queensland.
"With the region's dam levels continuing to fall, it's more important than ever that we conserve water wherever we can.
"If we all used four buckets of water less a day, together, we could reduce demand and ensure our dams are in the best position heading into summer.
"One of the easiest ways to save water is by reducing showers to four minutes. We know that the shower is the largest discretionary water user in the home, making up more than a third of daily water usage.
"Every minute reduced in the shower is a bucket of water saved, so we recommend using a shower timer or showering for the length of your favourite song.
Mr Cleary said another easy way to save water was to fix dripping taps and leaking toilets.
"A few drips from a leaking tap may not seem like much, but when multiplied over the course of a few days, months or a year, it's easy to see how precious those few drops are," he said.
"We estimate that dripping taps and running toilets contribute to more than 2 million litres of water being lost each year across the region, which is equivalent to the water supply of almost 144 households for a month.
"We're calling on everyone in our community to help us conserve our precious resource in any way they can. Changing a little at home, can save a lot of water."
