Water Quality

Water Quality

South Australia has unique water quality challenges. We have limited rainfall, and our population is spread across a large area. This can make treating and transporting water difficult. Our water sources include: the River Murray, surface water, seawater and groundwater.

Water quality is much more than just how water looks, tastes and smells (though these are important). It is also an issue of public health.

Keeping the quality of our water consistent as it moves through our water mains is no simple feat. SA Water manages 42 water treatment plants. These plants remove impurities, filter the water and disinfect it so it's safe to drink.

We are proud to be able to say SA Water consistently meets national water quality targets. You can read more about water quality by downloading our latest Annual Report.
