Glenelg Wastewater Treatment Plant, Adelaide, Australia

Remarkable collaboration results in development of critical infrastructure 

The upgraded Anderson Avenue Pump Station and the new Glenelg Inlet Works constructed by Fulton Hogan and designed by Aurecon are critical pieces of infrastructure that transfer sewage from the collection network to the Glenelg Wastewater Treatment Plant.

As locals and tourists enjoy the buzz of Glenelg Beach it is the upgrade of the Pump Station and Inlet Works making sure that wastewater overflows and odour is minimised in the area that covers the beach and its surrounds.

Glenelg Wastewater Treatment Plant now serves 200 000 people in the south west region of Adelaide.

A partnership approach

Aurecon teamed with Fulton Hogan and were appointed as the ECI design and construct team in August 2014. This Fulton Hogan and Aurecon team were later engaged for the detailed design and construction phases. Within 22 months of the ECI phase finishing the team had delivered both projects that took more than 98 000 site hours worked.

Sometimes there’s a tendency to overdesign infrastructure to make a product more robust or complicated than is necessary for its application. Throughout this project there was a focus on mitigating risks while achieving value and design interventions that would be practical and minimise costs wherever possible. The result is an example of remarkable collaboration between SA Water, Aurecon, Fulton Hogan and plant operator Allwater as innovation was created to deliver project objectives.

Glenelg Inlet Works

The new inlet works provides SA Water an opportunity to reduce odour release and provide a better environmental outcome for the community. The result is more efficient removal of the solid inorganic material such as paper, plastic, grit and silt which are abrasive and damage plant equipment.

The new grit removal technology uses less energy than the existing technology to minimise greenhouse gas emissions.

With all the innovations on this project it’s the design of a feature within the inlet works that attracted the most unique nickname – the lemon wedge: a concrete block in the shape of a lemon wedge designed to equally distribute wastewater flows to the four inlet screens. The escalator water inlet screens at a 45 degree angle then provide longer term value on safety and maintenance.

Anderson Avenue Pump Station

The Anderson Avenue Pump Station faced issues relating to the configuration, age and condition of structural, mechanical and electrical elements.

Heritage listed and originally built in 1901 the geometry of the pump station building wasn’t consistent. 3D scanning of the building gave the project team a detailed 3D dimensioning of the internal space so they could manipulate equipment installation methods and layout to suit the internal space available.

The use of 3D in the design enabled all key stakeholders to fully visualise the proposed final arrangements, aiding constructability, operations and maintenance reviews.

During times of low flow the pump station is now able to operate via the existing ‘tie line’ on electricity generated from sustainable fuel (methane) created through the digestion of wastewater sludge.


The project has won the following award:
