Until last week, the combined impacts of drought and bushfires followed by heavy rains meant that the levels of some metals in the local river water, particularly iron and manganese, were too high.

The metals are naturally occurring but in high enough quantities can be a health risk, as well as causing an unpleasant taste and staining laundry.

After extensive work, last week Kempsey Shire Council's Water and Sewer team were able to deliver a solution to deliver safe, clean water through a combination of bores and treatment processes, that ensures Willawarrin and Bellbrook tap water is of a sufficient quality.

Council's Manager Water and Sewer, Wes Trotter, said it was great to have Willawarrin and Bellbrook up and running with water from the river.

"There's a real sense of achievement to have Willawarrin and Bellbrook back on river water after the team have worked for months to get this result," Mr Trotter said.

"The events of the last 12 months have led to soil erosion, which has in turn impacted the quality of the water in the Macleay. These communities have borne the brunt of this as we've had to truck water in for months, so it's a great feeling to find a solution that should mean they can rely on the river going forward."

Council's Water and Sewer team remain focused on ongoing works to ensure the long-term water needs of the Kempsey community.
