Keppel Seghers' history spans close to four decades. The company's foundations were laid on 11 September 1974, when Seghers Engineering NV was incorporated.


In the 1970s, Seghers Engineering NV focused on wastewater treatment with aeration systems, the construction of waste combustion plants, as well as metal constructions, subcontracting and maintenance services.

The company developed the HARDpelletiser which turns sludge into a useful, environmentally-friendly product, the fluidised bed for cleaning of metal parts, and the ZEROFUEL fluidised bed technological solution, which is well-known as the best available technology for the combustion of sludge and other pasty wastes.

1980s and 1990s

The 1980s and 1990s marked Seghers Engineering NV's expansion in the Water, Solid Waste and Flue Gas Cleaning divisions, whereby Seghers Engineering Water NV and Seghers Engineering Solid+Air were founded to ensure the autonomous growth of the divisions. 

During this period, the various branches of Seghers Engineering were rebranded under Seghers Better Technology Group, with a new global structure for synergy.

In addition, several new technologies were acquired by the Group, including the UNITANK® technology, a space and cost saving biological wastewater treatment solution, the ROTARY ATOMISER technology for flue gas cleaning, and the DANO® drum technology for recycling and pre-treatment of waste.

It was also during this period that the first sludge dryer/pelletiser for communal sludge in Bruges (Belgium) was commissioned.

Early 2000s

Seghers Keppel Technology Group was incorporated in 2002, when Keppel Integrated Engineering (KIE) acquired the assets of Seghers Better Technology Group. 

Subsequently, the Group was integrated in 2005 with the rest of the environmental companies belonging to KIE to strengthen cohesion among all environmental activities. The Group underwent a global name change to Keppel Seghers, its present name.

The early 2000s also saw the launch of several new water treatment technologies, including UNIBRANETM technology for the treatment of highly polluted industrial wastewater and leachate for safe discharge, UNITANK® 3rd generation which combines advanced purification with extreme compactness and highest operation flexibility, as well as NEWATER technology for water reuse applications.

During this period, Keppel Seghers also placed strategic focus on long-term participations, including Design, Build, Own & Operate (DBOO), Build, Operate & Transfer (BOT), Build, Own, Operate & Transfer (BOOT), Public Private Partnerships (PPPs), license agreements and joint ventures.


Today, Keppel Seghers is a leading provider of comprehensive environmental solutions ranging from design and engineering, technology and construction to operations and maintenance of facilities. Its advanced technology solutions address a wide spectrum of environmental issues including solid waste and wastewater.

With the reorganisation of KIE and Keppel Energy in May 2013, Keppel Seghers also came under the wing of the then-incorporated company, Keppel Infrastructure.

Keppel Seghers' mission is to become a valued partner to its customers and contribute significantly to the preservation of its environment through the use of advanced technology solutions and leveraging on its extensive engineering experience and global network.
