Manly is serviced by the North Head Wastewater Treatment Plant, the second largest of the 30 wastewater treatment and water recycling plants in greater Sydney, the Blue Mountains and the Illawarra in Australia. It serves an area of 452km2, a population of over 1 million people and treats about 300 million litres of wastewater a day.
In 2009, Haigh was delighted to have been chosen to work with Sydney Water at their North Head sewage treatment plant and successfully completed an innovative underground screenings handling installation. The facility treats part of Sydney, including the Manly area, before being discharged out to sea by a long sea outfall pipe.
Equipment is located below ground in a series of caverns. Haigh equipment was chosen because of the complexities of the cavern system and the need to achieve clean screenings with low volume and low odour and which have to be transported by road through the Manly area.
The treatment plant saw a $100M+ upgrade with grit removal, screenings handling and many other areas being completely refurbished.
Since its installation, the equipment installed by Haigh has continued to operate successfully.
