Previous Projects

Jumbo Kingdom, Floating STP
Client: Aberdeen Restaurant Enterprises Limited (of Shun Tak Group)
Brief: design a waste treatment plant for the largest floating restaurant in the world

 

‘Jumbo Kingdom’, a major tourist attraction in Hong Kong Harbour, needed the ability to treat its own waste. The Heal Group was engaged after a number of other options had been looked at and rejected by AREL (Aberdeen Restaurant Enterprises Ltd). In 1996 Heal designed, project managed, provided equipment for, and commissioned a 1 Million litre/day “floating” facility. This facility is the first of its type in the world and is based on proven Australian technology, treating a very strong influent with very high oil and grease content.

Pagerungan Comprehensive Water & Waste Treatment Facility
Client: Pertmina Pagerungan Gas Centre
Brief: design, manufacture and install a totally integrated, comprehensive water supply and waste
management system.

 

Pagerungan Island is an environmentally sensitive island 120 nautical miles NNW of Bali. It has the only source of fresh water within an Island Group that supports five thousand people. The Heal Group was engaged by the Contract Managers to design a comprehensive water and waste water system that would protect the island’s only aquifer and, in addition, ensure no waste was to be left on the Island.


Heal designed, manufactured and installed:
- a reverse osmosis (RO) system where all potable water was drawn from seawater.
- a sewage treatment plant to produce effluent that was then passed through
- a “B” grade water treatment plant to provide all other water (grey), including construction water.
- a composting system for all solid waste, ie; kitchen, paper and timber.

 

This not only reduced its volume by two thirds but also produced a stable and valuable humus source for the area restorations required under the Main Contract.


This project is another excellent example of a remote island with difficult logistics, challenging design requirements that needed modification on the go, and a local work force that involved a deep understanding of the cultural requirements. All challenges were met with solutions that worked to create a successful project for all involved.

10 Sewerage Treatment Plants & 3 WTP for mining site, camps & township
Client: Porgera, PNG
Brief: Complete project

 

Porgera presented its own challenges, with local tension due to the contentious nature of the mine and its
relationship with the local people. Several companies had been forced to pull out of the region due to instability. Heal Group successfully completed the project through understanding of local culture, local connections and a suitable work process through which local elders were consulted and the workforce was predominantly local workers.

 

 

Christmas Island 1 M L/day Sewerage Treatment Plant
Client: Australian Federal Government
Brief: design, manufacture and install a waste water treatment plant for Christmas Island

 

On Christmas Island raw sewage was being released directly offshore. Over time this proved disastrous for the local eco system. The Heal Group, in association with Entact Clough of the Clough Group, designed a 1.0 Ml/day Sewage Treatment Facility to produce a good quality secondary effluent, so minimising the environmental impact. This project had two major challenges. Firstly the remoteness, and secondly the local fauna, the native Booby Bird. The problem of remoteness was solved by good project management, and the second problem, protecting the local fauna, was solved by the covering of the Treatment Facility with a tensioned fabric to act as a deflector. Both solutions worked well.

Lihir Gold Mine & Camps Modular STP
Client: Davey Kinhill Fluor Daniel & Lihir Gold Ltd/Newcrest Mining
Brief: provide a waste water plant that could be expanded over time

 

The Lihir Gold mine project utilizes the Heal modular units as they are excellent for projects needing the ability to expand over a number of years. Lihir Island is a remote island off the coast of New Ireland, PNG. Davey Kinhill Fluor Daniel developed the mine and engaged Heal Group to provide the water and sewerage treatment facilities. In 1995 Heal installed one balance tank and 2 treatment modules initially. As the mine expanded so did the sewerage plant, to four modules with 1½ balance tanks. The half balance tank was replaced with a full balance tank, and a further two modules in the next phase. A seventh module was installed in 2007, along with a refurbishment of the original units. A further balance tank and two modules were installed at Camp 4 in 2010. An eighth module is now in planning for future installation. To cope with the remote location and shipping, the treatment modules were designed with wheels so they could be landed from ocean‐going barges and towed to their location.

Manus Island Offshore Processing Centre
Client: Decmil Australia & Decmil PNG Ltd (Federal Dept Immigration & Border Protection)
Brief: Design, manufacture, supply and install Sewer and Water Treatment Plants

 

Heal Group was contracted to design the new sewage Treatment Plant, and the upgrade to, and augmentation of the existing water treatment plant for the new Australian Offshore Processing Centre on Manus Island. Despite being in PNG the contract required that all design, fabrication and construction was carried out in accordance with Australian building codes, and met the stringent Australian Standards. The location itself presented challenges with remoteness, quality of locally sourced materials, and weather. High strength ring beams were designed to handle the lack of information on ground stability for both the boltup tanks in the STP, and the 400k litre water storage tanks (top). All fabrication was carried out in Australia, and shipped to site for assembly and installation. The main water pumping station (right) is capable of pushing 143l/s, and along with the three 400kL water storage tanks, formed just part of the upgrade required. The extended aeration system STP specified in the scope by GHD had to be able to handle 1Ml. With water temperatures in PNG often in excess of 27⁰C special attention was required for the design, especially of the aeration, sludge handling and sequencing programs. On average the daily water temperatures are 31⁰C. The plant is also now managing sludge from another local STP.
