Our Innovation Program is delivering operational efficiencies, improved safety practices, enhanced customer and environmental outcomes and improvements to our workplace culture.

Through our Research and Development Program, we identify areas for future investment, conduct pilot and trials and work with industry and research partners to explore new and innovative ways to operate to benefit customers and the wider community.

Closely aligned to our strategic direction, our Innovation Program is empowering our employees, enhancing customer service and helping us achieve our purpose and vision.

We are the first utility in Australia to use unique ‘superbugs’ to take the waste out of wastewater! 

Wastewater is something we all generate by doing things like showering, washing up and using the toilet, and it needs to be treated once it goes down the drain.

In an exciting step forward we have introduced amazing anammox bugs into Queensland’s largest sewage treatment plant.

The bugs have an amazing ability to feed on nutrients in wastewater, naturally removing them and saving large amounts of power and chemicals in the process.

They make the essential process better for the environment and much more efficient which is great news as more people call south-east Queensland home.

Healthy Waterways 2015 Water Services Award

Our Beaudesert Nutrient Offsets Project was awarded the Healthy Waterways 2015 Water Services Award. In an Australian-first, the project:

  • regenerated and rehabilitated an eroded riverbank to prevent five tonnes of nitrogen and 11,000 tonnes of soil from entering the Logan River
  • avoided an $8 million upgrade to the Beaudesert Sewage Treatment Plant. 

Healthy Waterways Government Stewardship 

We were also ‘Highly Commended’ in the Healthy Waterways Government Stewardship category in recognition of:

  • our unique partnership with the Bulimba Creek Catchment Coordinating Committee (B4C)
  • rehabilitating more than 30 sites
  • planting over 25,000 native trees, covering an impressive area of 236,000 square metres
  • improving the long-term health of urban waterways.

Australasian Society for Trenchless Technology 

In 2015 we were proud to achieve top honours from the Australasian Society for Trenchless Technology in recognition of our:

Algae are very simple microscopic plants that grow in water. They form the base of the aquatic food chain, and thrive in nutrient-rich waters like sewage, animal wastes and industrial effluent. When algae are introduced into wastewater, they not only purify it, but also create biomass and oils, able to be used for fuel, food, feed, and other products.

Algae are fast growing, and can double their numbers every few hours, which means it can be harvested daily, and have the potential to produce a volume of biomass many times greater than that of our most productive crops on land.

Like any other plant, algae also consume carbon dioxide (CO2) as they grow; releasing oxygen (O2) for the rest of us to breathe. It is estimated that approximately 50% of the oxygen we breathe originates from algae. Due to both the environmental and economic benefits of algae based wastewater remediation, algae will play an important role in future sustainable wastewater treatment.

We’re testing here in these algae raceways to find out what conditions they like best. In the future, we’re planning to introduce algae-based treatment at some of our regional plants. It’s a low-cost solution that’s ideally suited to areas with small populations. And best of all, it’s great for the environment because the process also generates useful by-products that can be used as fertiliser and fuel for possible commercial use.

They look like a floating mattress but they are far from a resting place. These floating wetlands are a Queensland first, working 24/7 to purify sewage at the Forest Hill Sewage Treatment Plant near Laidley.

The mattresses are part of an innovative trial to grow wetlands on specially engineered plastic mattresses, which are then floated on purpose-built lagoons. Queensland Urban Utilities’ Michelle Cull, said it was a natural, cost effective and energy efficient solution to purifying sewage.

The roots of the plants dangle beneath the mattress drawing out unwanted nutrients such as carbon, nitrogen and phosphorus, cleansing the water by trapping sediment and removing toxins. It’s a great example of green engineering and also has the potential to reduce operational costs at the plant. If the trial is successful, it will be rolled out at similar regional sewage treatment plants.

By harnessing the abundance of sunshine and space across the Scenic Rim and Lockyer Valley, we are using solar energy to power our sewage treatment plants to benefit our customers, local community and the environment.

Five hundred and fifty solar panels have been installed generating 134 kilowatts of green electricity, cutting grid power use at the facilities by more than 20 per cent. This is equivalent to taking 61 cars off the road for an entire year.

We are one of the first water utilities in Queensland to use solar power in this way, future-proofing sewage treatment with renewable energy.

What can be done with seaweed, and why is a water utility so keen on farming it?

As a part of our innovation program, and in partnership with the Sunshine Coast University, we’re currently exploring options to farm seaweed in Moreton Bay, to assist the balance of nutrients in our waterways. Nutrients are naturally abundant in the environment but are also a by-product of human activity. They can enter our waterways through sediment, effluent from sewage treatment plants, and agricultural and industrial run-off.

Seaweed naturally feeds off these nutrients, like nitrogen and phosphorus. It’s also the largest marine crop in the world, but is not yet grown commercially in Australia. However, we’ve found that the Queensland coastline is the perfect setting for a new seaweed industry, with ample light, warm water, and state-of-the-art aquaculture facilities, partnered with smart industries.

Seaweed production in Moreton Bay has the potential to become an alternative nutrient offset in our waterway. This innovation aims to conduct the first Australian trial of seaweed production in Moreton Bay. If successful, this could lead to utilising aquaculture as an offset for nutrient releases to waterways.

You can read more information on Nick’s (Sunshine Coast University) seaweed study here.

Currently, wastewater utilities spend up to 25 per cent of their energy budget to remove nutrients from wastewater, mainly nitrogen and phosphorus.  In sewage, these nutrients come primarily from people’s urine, rather than faeces or greywater.

The UGold electro-concentration system, developed in partnership between Queensland Urban Utilities and the University of Queensland’s Advanced Water Management Centre, is the world’s first technology specifically designed to remove and recover these nutrients right at the source – the loo.

This innovation has the potential to significantly reduce the cost of wastewater treatment.  The nutrient recovery system also generates a concentrated liquid fertiliser and a solid product (ammonium bicarbonate) that has multiple reuse options.

We’ve installed a pilot plant at our Innovation Centre at Luggage Point to conduct tests on real urine. The process is self-powered by a battery-like system with the energy contained in the urine itself. This technology is entirely chemical free and only requires minimal electricity.

The trial will provide us with invaluable data around upscaling the technology for more sustainable wastewater treatment in the future.

We are currently trialling an internationally-renowned leak detection software system called TaKaDu, which allows us to monitor the pressure in our network and detect leaks before they become bursts. This technology provides alerts, reports and real-time insights about our network, meaning we can catch issues early, avoiding costly repairs and the inconvenience a burst may cause our customers, such as a water outage.

Our Poo Car runs on electricity generated from sewage at our Oxley Creek Sewage Treatment Plant in Brisbane's west. 

We're converting the waste from 300,000 people into electricity, to run both this electric car and our sewage treatment plant. By harnessing the power of poo, we're not only reducing our operating costs but helping the environment by using a cleaner, greener energy source.

The electricity used to charge the car - a Mitsubishi innovative Electric Vehicle (i-MiEV) - is produced by our cogeneration unit. Cogeneration involves capturing the biogas produced from sewage sludge, then using it to drive an engine which creates electricity.
