Up A Dry Gully

Welcome to Up a Dry Gully

Let's get wise about water, South East Queensland! Let our H2O Kids program take you through the water story, the natural and urban water cycle, the role of catchments, how we use water and the future of water.

All experiences and resources are linked to the Australian Curriculum.

H2O Kids program

Learn More

Seqwater’s H2O Kids is an integrated educational program, consisting of a suite of experiences and resources for teachers and students from Prep to Year 12.

The program inspires students through storytelling and inquiry-based learning at schools or at an Seqwater site.

Seqwater dams

Learn More

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.

Water storage is our business.

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.


Healthy catchments

Learn More

High quality water supply begins at the source - our catchments!

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.


The water cycle

Learn More

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.

Water is essential for sustaining life on this planet.

The process of delivering safe, reliable drinking water to homes or businesses is an interesting journey.

Water treatment

Learn More

The South East Queensland region has some of the highest quality drinking water in the world.

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.

Water supply

Learn More

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 Service Providers and local governments are the primary suppliers of water to your home.

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.
