A history with us
Our Foundation
In 1984, Wastech was founded to produce organic fertilisers. Within a few years, Wastech business grew to include the design, supply and installation of irrigation systems.
In 1993, Wastech Engineering and Wastech Multigreen were formed, allowing each subsidiary to specialise on their markets, irrigation engineering and fertiliser manufacture respectively.
In 2001, Wastech Engineering expanded internationally, setting up Wastech Engineering International in Hong Kong.
In 2020, the merger of our three subsidiaries into the Wastech Group has enabled us to leverage our core competency operating in both fertiliser and irrigation engineering segments to provide end-to-end solutions to meet the needs of our customers and to also provide us with new business opportunities and growth.
Irrigation Engineering Specialist
Our Irrigation Engineering journey began with Wastech Engineering Malaysia in 1993 where we undertook the design, supply, installation and commissioning of irrigation systems mainly for agriculture irrigation engineering projects in palm oil nurseries and orchards.
In 2001 we further expanded our Irrigation Engineering business to Hong Kong through Wastech International to service landscape irrigation engineering projects specialising in recreational parks, infrastructure development projects and government buildings.
Some of the notable landscape irrigation engineering projects we have undertaken include a global theme park located in Penny’s Bay Lantau Island in Hong Kong, Hong Kong-Zhuhai-Macau Bridge, Queen Hill Zero Irrigation, Kai Tak Sports Park and work has also been performed in many regions of South East Asia including Malaysia, Singapore, Macau, Brunei, Indonesia, Pakistan Taiwan and China
