About Us

Dayen Environmental Limited was founded in 1986 by Mr John Lee and Mr Kor Hock Lai. Over time, we have evolved into a specialist environmental engineering company, focusing on providing integrated systems for waste and water treatment.

At Dayen, we are your partner for clean water.

We provides comprehensive solutions for clean water. We are a single-source provider of engineering, field construction, project management and operations and maintenance services to municipal, industrial and commercial customers.

Specifically, we design and build water treatment system packages for municipal and industrial customers. We also undertake turnkey projects in the form of Engineer, Procure & Construct (“EPC”). In addition, we manufacture and trade environmental equipments for our customers. Lastly, we invest in water treatment facilities under various schemes such as Design, Build, Own & Operate (DBOO), Build, Own, Operate and Transfer (BOOT), and Transfer Operate Transfer (“TOT”).

We embrace advance technology in our applications such as membrane in MBR, Desalination and Ultra-pure water. At the same time, we also use conventional treatment methodologies where appropriate. Our aim is to provide cost effective, efficient and value-added solutions to our clients.

We had successfully completed more than 800 jobs since our incorporation in 1986, with project value ranging from a few thousands dollars to multi-million dollars. The large and complex nature of these projects demonstrate our capabilities both technically and financially.
