Improving catchment health and water quality

Water quality starts at the source – our catchments. We work in partnership with our neighbours, catchment land owners and the broader community to improve catchment health and water quality.

Extensive monitoring is a core component of responsible catchment, storage and supply management. Seqwater has a team of 43 professionals that ensure compliance with our water quality and environmental obligations.

Working collaboratively with a range of partners, Seqwater is constantly developing better water quality monitoring techniques and methods aimed at providing more timely and comprehensive feedback for informed decision making. These improved techniques complement existing monitoring programs across our storages.

Water undergoes regular and thorough testing at many points of the treatment and distribution system. We undertake almost 400,000 water quality tests a year to meet our regulatory requirements and ensure community confidence. We test for a wide range of other parameters outlined in the Australian Drinking Water Guidelines 2011.

We continue to publicly report on the quality of water through the Customer Confidence Report. This monthly report outlines the water quality of the region’s bulk water supply against 14 key health and aesthetic water quality parameters widely considered to be most relevant to drinking water quality.

Water quality and recreation

We are the only bulk water supplier in Australia that manages open catchments, allowing the community to enjoy our water supply lakes and catchment land for recreation activities. Our challenge is to balance community access with our essential role of ensuring a high quality water supply for the region. Download the Water quality and recreation factsheet for more information.

Seqwater monitors all lakes for the presence of blue-green algae. When toxin concentration levels indicate a health risk, we may restrict lake access for primary contact (in-water) activities such as swimming, skiing and tubing, as well as issuing an advisory notice that secondary contact (on-water) activities such as boating, paddling and fishing is not advised.
