Logan City Council is an innovative, dynamic, city of the future.

In the 2018/2019 financial year Logan City Council delivered a number of award-winning infrastructure and community development projects. These projects attracted national attention for their environmental sustainability, engineering excellence and use of new technologies. The project highlighted is just one of the many hundreds of developments and improvements being made across the city every year.An artist’s impression of a future Springwood.

The Challenge:

The Travis Road reservoir complex provides water to a growing population in
Yarrabilba and parts of
Logan Village.

What did we do about it?

Previous planning identified that 12 megalitres (ML) of water storage will be needed to meet population growth.

Economic Development Queensland commissioned us to build two 6ML reservoirs.

The first 6ML reservoir was delivered in 2018/2019 and the second 6ML reservoir is expected to be delivered by around 2031.

The project included construction of a new 34m diameter, seven-metre high concrete reservoir.

Works included:

  • Design and construction of a 6ML reservoir.
  • Earthworks for two 6ML reservoirs including creating a pad ready for the second reservoir to be constructed in future.
  • Connection pipework to the existing inlet and outlet mains (with allowances for future pipework).
  • Installation of an access road and associated earthworks.
  • Modifications to electrical, chlorination and solar energy controls.
Challenges for this project included excavation, rock-breaking and stabilization of a large exposed rock face. The project took approximately 34,500 working hours. There were no lost time injuries and no significant environmental impacts.

project highlights:

Managing growth in Logan.The construction of a wastewater treatment plant at Cedar Grove.

The Challenge:

The Greater Flagstone area will experience substantial residential, commercial and industrial growth. Appropriate infrastructure needs to be built to accommodate this growth.

What did we do about it?

  • In 2018 we started building stage one of a new state-of-the-art wastewater treatment plant (WWTP) located at Cedar Grove.
  • The new WWTP will service the Queensland Governments Greater Flagstone Priority Development Area (PDA) . Population is forecast to reach more than 145,000 people when completed.
  • The WWTP is to be built in several stages.

Stage one will provide services to approximately 20,000 people and treat up to 3.3ML of wastewater per day.

Construction of this stage is expected to be complete by mid-2020.

Works included:

The plant will use membrane bioreactor technology and a system of constructed wetlands to treat wastewater to an ultra-high standard.

An on-site solar farm will generate energy for treatment operations. Council plans to revegetate parts of the site including the banks of the Logan River.

About 100 community members worked with the project team to kick start this process by planting up to 2,000 native trees, shrubs and grasses.

The WWTP will be connected to developments in the Greater Flagstone PDA by approximately 19km of trunk wastewater pipelines and four new pumping stations.

The Challenge:

Clutter in the form of non-mandatory safety documents, makes safety in the field a bureaucratic process.

This increases safety risks and reduces work-site productivity for our field staff.

What did we do about it?

We teamed up with Griffith University’s Safety Science Innovation Lab to deliver the first phase of a safety decluttering project.

The project is a joint Council initiative with our alliance partners and Griffith University.

Safety clutter exists in the form of non-mandatory documents, roles and activities that reduce work-site productivity.

The research project was designed for Council’s water infrastructure renewals program. It tests whether ‘decluttering’ safety processes could enhance work site productivity.

The research has implications for the wider infrastructure development industry and government.

Research field work was conducted in 2018/2019.

Works included:

Researchers observed three construction crews working on the alliance’s wastewater and water network renewals projects. Two of the crews worked in ‘decluttered mode’ on construction sites while one did not.

In decluttered mode, the crews operated under the contractors’ safety management systems rather than the alliance’s.

Studies of the crews and their work sites showed safety documents and procedures had little to do with maintaining worker safety.

Safety management was in-built into each team’s culture and processes.


  • Safety decluttering enhances productivity and communication about safety.
  • Decluttering substantially improves the amount of non-paperwork that a supervisor can perform.
  • It improves crew productivity by saving time at the start of the day.

Building our infrastructure.Council workers on the partially completed replacement roof of the Hillcrest reservoir.

The Challenge:

The Hillcrest reservoir complex provides drinking water to almost 54,000 people in Logan. The challenge is to ensure that the city’s water infrastructure network meets residents demands.

What did we do about it?

Council invested to improve the Hillcrest reservoir complex to maintain a reliable, safe drinking water supply for residents.

The complex provides drinking water for almost 54,000 people in:

  • Browns Plains.
  • Hillcrest.
  • Forestdale.
  • Boronia Heights.
  • Regents Park.
  • Heritage Park, and.
  • Park Ridge.

It includes two, 20 million litre ground level storage reservoirs, a major water pump station and the iconic Wineglass reservoir.

Works included:

The Wineglass is a 35m, tower-style reservoir.

It holds a million litres of water and is known for its ‘champagne bubble’ feature lighting at night.

Bulk water is delivered to the reservoir from two sources:

a Kuraby water main from the north and the Southern Regional Water Pipeline from the west (both operated by Seqwater).

The water pump station on the site can deliver up to 500 litres of water per second to the Wineglass.

It will fill every 45 minutes under normal operations.

The pump station was recently upgraded.

It has four new 110kw pumps and variable speed drives, new switchboards and other infrastructure.

Making water treatment environmentally sustainable.An aerial photograph of Round Mountain Reservoir solar-powered water treatment plant.

The Challenge:

As we continue to build and update our water infrastructure, we need to think of ways to achieve environmental sustainability.

What did we do about it?

We harnessed the power of sun and salt in an Australian first solution for treating drinking water quality in a remote location.

The multi-million dollar project at Round Mountain Reservoir in the City of Logan’s south west combines solar power, commercial battery storage and electro-chlorination technologies to maintain water quality for residents, 24 hours a day.

The solution is transferrable to other Councils and utilities operating in remote locations.

Works included:

Logan’s environmentally sustainable project, which provides water to our growing southern suburbs has received widespread industry acclaim.

  • Engineers Australia—Queensland Engineering Excellence Award.
  • Australian Water Association (Qld)—Infrastructure Innovation Award.
  • Institute of Public Works Engineering Australasia (Qld)—Innovation and Sustainability in Water: Projects under $5 million.
  • Institute of Public Works Engineering Australasia (Qld)—Overall Project of the Year.

The project was also highly commended at the 2019 Australian Water Awards.

Innovation in asphalt.Council workers laying asphalt.

The Challenge:

With nearly $30 million a year spent on rehabilitating roads, Council needs to reduce costs, extend pavement life, enhance worker safety and improve environmental performance.

What did we do about it?

We trialled two technologies this year which have the potential to solve some of these challenges. One is a Queensland first and the other, an Australian first.

As our road network infrastructure increases, so too does the cost for its maintenance.

Council is testing different types of asphalt to see if we can reduce costs, extend pavement life, enhance worker safety and improve environmental performance.

Our Council identified and trialled two technologies this year.

They have the potential to solve some of the city’s road surfacing challenges:

Works included:

Fibre reinforced asphalt uses Forta-Fi Fibre; a heat-resistant blend of aramid and polyolefin fibres which are mixed into asphalt (at the asphalt plant) . The fibres cannot be seen in the finished product.

EME2 is a high modulus asphalt technology used to build hard wearing roads with a reduced base course thickness.

Expected benefits of using the innovative asphalt products are:

Fibre reinforced asphalt:

  • Reducing the frequency of disruptive road reconstruction and resurfacing projects in urban areas.
  • Reduced vehicle wear and tear for motorists from a smoother road surface, for longer periods.
  • Immediate capital cost savings due to the reduced thickness of pavement required for structural repairs on fibre reinforced asphalt. In some cases, fewer asphalt layers were needed.
  • Delayed road surface cracking, partly achieved by reducing the amount of water entering the pavement through cracks in the surface.
  • Reduced maintenance costs associated with filling cracks, ruts and potholes in roads, and resurfacing roads.

EME2 warm mix asphalt:

  • Uses up to 30 per cent less energy used to produce warm mix asphalt compared with hot mix asphalt.
  • It reduces greenhouse gases and other emissions during production and installation of asphalt.
  • Increased community satisfaction by reducing the time it takes to install warm mix asphalt surfaces allowing roads to be opened sooner.
  • A safer workplace, with reduced risk of burns and inhalation of fumes for road workers, due to handling lower temperature asphalt.
  • Higher productivity and reduced costs on road projects as multiple layers of a road surface can be installed in a single work shift. This should help Council to rehabilitate more roads.

project highlights:

Restoring our most recognisable landmark.The restored Red Bridge expanding the Logan River at Beenleigh.

The Challenge:

The iconic ‘Red Bridge’ over the Logan River between Beenleigh and Loganholme is now a much-loved pedestrian and cycle link in the Logan River Parklands, which needed some restoration to its structure.

What did we do about it?

In a first for Council, Building Information Modelling (BIM) was used to determine the most cost-effective repainting and maintenance program for the bridge.

The iconic Red Bridge over the Logan River between Beenleigh and Loganholme was built in 1931 to carry road traffic.

It is now a much-loved pedestrian and cycle link in the Logan River Parklands but in recent years, it has been deteriorating.

Works included:

In a first for Council, building information modelling (BIM) was used to document the bridge’s design, condition and rehabilitation options in a three dimensional, digital environment.

BIM helped the project team to determine the most cost-effective rehabilitation and maintenance program for the bridge.

It determined how to manage constraints such as constructing scaffolding over water, working near power lines and a busy motorway.

In simple terms, BIM enabled the team to deliver the project in the “virtual world” before appointing a contractor to improve the bridge in real time.

The Red Bridge is the City of Logan’s most recognisable transport asset—a landmark, tourism icon and artists’ muse.

The repainting of the bridge will ensure that it remains striking for decades to come.

From cup to paper.

In keeping with Council’s commitment to minimising everyday environmental impacts the Annual Report for 2018/2019 was printed on paper manufactured from recycled coffee cups. The paper is printed on Ball & Doggett Extract. 90 per cent of waste from each cup is turned into Forest Stewardship Council (FSC) certified paper fibre. The remaining 10 per cent, which is plastic, is used elsewhere. About 2.7 million disposable coffee cups are consumed every day in Australia, with fewer than one in 400 being recycled. Through the use of this paper we aim to inspire better awareness of waste and its impact on the environment.
