Seqwater

Seqwater Seqwater is SEQ's bulk water authority, responsible for providing a safe and secure water supply.

We also provide essential flood mitigation, irrigation services to 1,200 rural customers in 7 water supply schemes and manage recreational areas visited by 2 million people a year. We are one of Australia's largest water businesses, with the most geographically spread and diverse asset base of any capital water authority. Our operations extend from Gympie to the New South Wales border, and west to

the base of the Toowoomba ranges. We manage $10.8 billion of water supply assets and natural catchments of the region's major water supply sources, including dams/weirs, water treatment plants and climate-resilient water sources like the Gold Coast Desalination Plant and Western Corridor Recycled Water Scheme. Seqwater was formed on 1 January 2013 through a merger of 3 state-owned water businesses, SEQ Water Grid Manager, LinkWater and former Seqwater. We also assumed responsibilities undertaken by Qld Water Commission, such as the long term planning of the region's future water needs.

Every night, a gardener with a 1-metre wingspan clocks on across South East Queensland. 🦇

Meet the Grey-headed Flying-fox — one of Australia's largest bats. Come sunset, they leave their camps and can travel up to 50km in search of food: native fruit and the nectar and pollen of trees.

As they feed, they carry pollen from tree to tree and spread seeds across the land, helping new trees grow. Every flight helps keep our native forests healthy — the same forests that help hold riverbanks together, provide shade over waterways, and support the catchments that supply our drinking water.

So next time you see a stream of flying-foxes crossing the evening sky, you're watching these hard-working gardeners clock on for the night shift. 🌙

Wear It Purple Day started back in 2010, after too many young people were made to feel that being themselves made them less welcome — at school, at work, wherever they turned up. More than a decade on, it's still worth showing up for.

South East Queensland's going to need engineers, scientists, dam operators and tradies for a long time yet. We'd rather none of them spend the workday hiding who they are. Good people doing good work, and everyone deserves a fair go at it.

You're welcome here as you are. 💜

Fifty years. That's how long Hinze Dam has been part of the Gold Coast's water supply! A fitting milestone to celebrate this World Water Week. 🎂 💧

Behind the showers, cuppas and garden hoses, there's a crew who keep the place ticking. We asked a few of them what they think is the best part of working out at Hinze 💬

🎂 North Pine Dam and Water Treatment Plant turns 50 this month — half a century of helping supply drinking water to homes across SEQ.

We asked a few of the crew what they love about the place. Mark’s still finding reasons after 31 years on the job!

Ever wondered why some water storages sit high up instead of on the ground? 🤔

It's all about water pressure.

The higher water is stored, the more pressure gravity creates to push it down and through the pipes.

Pumps move treated water up into the elevated storage— switching on when the tank runs low, then off again once it's full. From there, gravity does much of the work.

Without that height, pumps would need to work much harder to maintain pressure across the network. They'd be constantly cycling on and off as water is needed, using more energy and wearing out faster.

Think of it like driving. Stop-start traffic can use more fuel than cruising steadily along the highway. 🚗

Storing water up high lets pumps do a simpler job. They're still used across the network wherever they're needed — they just don't have to work as hard, thanks to gravity helping keep the pressure steady.

Did you know gravity was doing so much of the work every time you turned on a tap? 🚰Happy National Science Week!

🔎 Did you know pH measures how acidic or alkaline a substance is? For example, your favourite soft drinks are about pH2.5, orange juice is pH3.8, a glass of milk is pH6.7 and many bottled spring or mineral waters are over pH8.

We’re enhancing water treatment processes at Mount Crosby, and North Pine and Beaudesert water treatment plants to strengthen water quality by slightly increasing the pH level from about 7.8 to about 8.4.

What does this mean for you?

✅ Still safe to drink ✅ Still meets the Australian Drinking Water Guidelines.

Most people won’t notice a change in the appearance or taste of drinking water – however some customers who treat their water or have specific water chemistry requirements may need to make adjustments to allow for the change in pH.

👉 To find out more about what this change means for you, please contact your local water service provider Urban Utilities Unitywater Logan City Council or visit our website: https://www.seqwater.com.au/continuous-improvement

💧 Quick question: What do coffee, tomatoes and your tap water have in common?

They all have a pH level.

From next week, we're making a small adjustment to the pH of drinking water supplied from our Mount Crosby, North Pine and Beaudesert water treatment plants.

The change is slight, from around 7.8 to 8.4, and most customers won't notice any difference.

So why do it?

Because small changes behind the scenes can help us deliver more stable water quality, especially during the warmer months when water quality needs closer management.

Ever wondered where your tap water actually starts? 👀 🚰

Not the treatment plant — before that. Up in the catchments, where the rain lands and finds its way down to the dams or ocean.

Those catchments often need a helping hand. It's , so it's a good time to say cheers to the folks putting in the work 👏 — removing weeds, planting trees, working with landholders to get the most from our land, while maintaining the environment.

Good for the water. Good for the fishing. Good for keeping these spots around for the next generation.

Through our Source Protection Partnership program, we team up with more than 30 landcare pros and hundreds of landholders to keep our water supply catchments in good nick. Healthier catchments mean cleaner water heading into the dams and ocean — and less complexity to treat it before it reaches your tap.

Right across the country there's over 6,000 Landcare groups and 100,000-odd volunteers pitching in. If you've ever thought about lending a hand close to home, this is the week to have a squiz! 👉 Landcare Australia

📢 Seqwater is enhancing water treatment processes by slightly adjusting the pH levels in our water at Mount Crosby, North Pine and Beaudesert water treatment plants, delivering water quality benefits across Brisbane, Ipswich, Logan, Moreton Bay, and some parts of the Scenic Rim.

The enhanced treatment processes will help deliver longer-lasting water quality benefits by further stabilising water quality in our network, including during the summer months when water quality needs to be more closely managed ☀️

While domestic users are unlikely to notice any difference in the taste of their drinking water, some specialised or large‑scale water users such as hospitals, major food and beverage producers, aquariums, or facilities with cooling towers may need to review and adjust their own treatment processes or dosing settings to align with the increased pH levels.
