Once home to Sonic the Hedgehog and Friends at the SEGA World complex, Darling Harbour was seen as a prime waterfront location ripe for redevelopment in 2009.
The commercial building industry is looking to suppliers such as Grundfos to provide solutions that help achieve sustainable outcomes; both in terms of energy savings and reduced water use.

A new kind of park
Completed in 2011, the new AUD 500 million development, known as Darling Quarter, includes of Commonwealth Bank Place, two eight storey campus style office buildings with 58,000m2 of office space. A new pedestrian link has created a Civic Connector – a gateway for pedestrians between the east and west of the city and Darling Harbour waterfront. Darling Quarter also features a new 4,000m2 state of the art outdoor children’s playground.
Grundfos pumps everywhere
When it comes to water, Darling Quarter saves a massive 92% on mains water consumption compared to conventional office buildings. This is achieved by a combination of water treatment and reuse and rainwater harvesting.
Both solutions feature Grundfos pumps – in fact, more than 50 Grundfos pumps are installed throughout Darling Quarter precinct. The selection of quality, Danish designed Grundfos pumps was made by the hydraulic consultants at Warren Smith & Partners and mechanical consultants at Arup in consultation with Lend Lease.
When it comes to water, Darling Quarter saves a massive 92% on mains water consumption compared to conventional office buildings.
The list of pumps supplied by Grundfos to the project include:
• Grundfos NB pumps for air conditioning circulation
• Grundfos Dual UPS (N) pumps for the hot water system
• Grundfos Hydro MPC for recycled water
• Grundfos Hydro MPC for cooling tower make up water
• Grundfos Hydro MPC for potable water
• Grundfos BM, SEG & CR pumps used in water recycling
• Grundfos SP pumps for rain-water reuse
• Grundfos SEG submersible pumps for sewage and stormwater pump outs
The partnership between Grundfos, Warren Smith & Partners, ARUP and Lend Lease proved to deliver the most sustainable solution possible.
Demonstrating how modern, sustainable buildings and developments can benefit the environment, the Darling Quarter project includes state-of-the-art water saving solutions. After all, why use perfectly good, potable water for watering parks? Using rainwater instead allows Darling Quarter to assist the Sydney Harbour Foreshore Authority in conserving its precious drinking water. In total, the rainwater reuse will save up to 60 million litres of drinking water per year.
At the forefront of the drive to save potable water is the rainwater harvesting system installed at the Darling Quarter site. Designed by Warren Smith & Partners, it consists of a 300,000 litre underground tank, together with Grundfos BM, CR and Hydro MPC pumps and treatment systems to collect rainwater for irrigation of the Public Domain Park and gardens.

The Darling Quarter site also features other measures that contribute to saving precious potable water. These include an on-site recycling water plant located in the basement of the Commonwealth Bank Place office buildings. Though only taking up 200m2 of space, the treatment plant is able to produce 166 kilolitres of treated water daily. This water is used for toilet flushing, irrigation and cooling tower make-up water.
More Grundfos pumps
The treatment plant also utilises Grundfos pumps. Grundfos installed factory assembled and tested pump sets and control panels. The pump sets consist of cast iron SEG grinder pumps for sewage and brine return to the municipal sewer main. Combined Grundfos BM booster pumps and CR centrifugal pumps are utilised in the treatment process.
