Take a journey with Seqwater from catchment to tap.
Up a Dry Gully is an online resource portal that helps you learn all there is to know about the water cycle - from source, store and supply.
An informed and knowledgeable South East Queensland community is important to securing the region's long-term water future. Through education we can achieve water for life - now and for future generations.
South East Queensland catchments cover more than 1.2 million hectares of land. Seqwater only owns around 65,000 hectares of this land, so it is vital we work in partnership with our neighbours, catchment land owners and the broader community for better land management and water quality outcomes.
A healthy catchment is the first step in having a high quality water supply for our region.
We all need to do our part to keep our waterways healthy.
Seqwater owns and operates 26 dams, 51 weirs, and 14 bores and aquifers across the region. Twelve key dams supply as much as 90% of South East Queensland’s drinking water.
Water from Seqwater dams supplies our water treatment plants and irrigation schemes, and also contributes to environmental flows in downstream rivers and creeks. During times of heavy rain, we can store additional water in these dams and make controlled releases in order to reduce the volume of water flowing down the Brisbane River.
Around 50 per cent of the Brisbane River Catchment is below Somerset and Wivenhoe Dams, including the Bremer River and Lockyer Creek. This means their flows cannot be controlled by our dams.
While the primary purpose of our dams is water supply, many also provide the community with recreation facilities, both on the water and in the areas around the lakes.
South East Queensland’s drinking water is predominantly sourced from dams.
Our dams are used to provide a safe and sustainable water supply to the region and, for some of our dams, flood mitigation.
The water cycle, or the hydrologic cycle, is the continuous circulation of water that falls from the sky (precipitation), runs off the land (run-off), is collected (rivers, creeks and streams), enters groundwater and aquifers (infiltration) and then returns to the sky (evaporation) to follow the cycle again.
The process of delivering safe, reliable drinking water to homes or businesses is an interesting journey.
At an Seqwater water treatment plant, water is cleaned and prepared for drinking. All water that has been through a water treatment plant must adhere to the stringent Australian Drinking Water Quality Guidelines.
The basic water treatment processes include coagulation, flocculation, sedimentation, filtration and lastly, disinfection of water.
Our North Pine and Mt Crosby Westbank water treatment plants can treat 250 megalitres of water a day. It normally takes about one day to treat water from intake until storage for subsequent supply to homes and businesses.
Explore our treatment plants, water supply system, and catchments with our suite of virtual tours.
After processing at the water treatment plant, water is ready to be supplied to homes and businesses.
Treated water is pumped into the bulk water supply network for distribution to your tap!
Water utilities such as Queensland Urban Utilities and Unitywater as well as Council water businesses including Gold Coast Water, Redland Water and Logan Water, supply water to your home.
