Hydromaster is a Singapore-based water and wastewater treatment company, and we commit to develop a range of state-of-the-art membrane systems and to deliver quality, timely and cost-effective results to our clients.

Our management has been involved in building many of Singapore’s sewage treatment plants with PUB Singapore (e.g., 55 MLD Bedok NEWater Factory; Jurong High Grade Industrial Water Project), designing and supplying to one of the largest treatment plants in Malaysia and several projects in Indonesia, Thailand, Philippines and Vietnam.

With over 20 years experience in treating, as well as recycling, water and wastewater treatment in Asia, our team of experts and engineers are able to provide a wide range of cost-effective solutions tailored to your requirements, be it for producing potable water, high grade industrial water, boiler feed water, industrial waste water, or sewage treatment.

We also provide on-site technical consultation, process design and process warranty, training, service and maintenance.

We strives to engineer competitive, comprehensive and customised water solutions that are simple, easy to operate and robust to gain a significant market share in defined sectors.


We are the business, engineering and investment partner of our clients in developing latest and most competitive membrane-based technology solutions for competitive water supply to the industrial, commercial and municipal sectors.

We provide engineering design and consultancy for global applications with nearby test-bedding of various capacities (e.g., 1 to 50 MLD) through BOO/BOT or other business models. Following are some highlighted applications:

  • Municipal water supply
  • Commercial and industrial water supply and recycling
  • Membrane Bio-Reactor (MBR) wastewater
  • Semiconductor wastewater recycling
  • Solar panel wastewater recycling
  • Desalination
  • Rubber industry wastewater recycling
  • Fracking oil water recycling
  • Laundry water recycling
  • Petrochemical water recycling


  • Undertake the role of an alternative Water Resource Supplier, in providing water treatment system replacement for Municipal supply, or designing new water treatment solutions to reduce capital expenditures (capex) and operating expenses (opex). A win-win solution for both the client and ourselves.
  • Provide long-term Build, Own, and Operate (BOO) or Build, Operate, and Transfer (BOT) contract to supply quality water at a certain pre-determined quantity, quality and rate. Within contract period, the client is committed to receive water at an agreed rate and quantity per day. The contract may include transfer of plant at a later date.

Continuous R&D to develop most competitive membrane-based technologies in the market including Ultra-filtration (UF), insert hollow fibre membranes (PAN, PVDF and PTFE materials), Nano-filtration (NF), Reverse Osmosis (RO) and Bio-filtration. R&D is backed up by key management team of 20 years engineering experience in various fields, ranging from wireline field, technology commercialisation, to energy optimisation.


All of Hydromaster treatment systems are:

  • Low energy
  • No or minimal chemical use
  • No or minimal sludge or discharge
  • Simple to operate and automate (engineered according to your needs)
  • Robust
  • Compact / small footprint
  • Low capital expenditures (capex)
  • Low operational expenses (opex)


Full access to manufacture and/or assemble of membrane systems in Singapore. We also provide design and customised solutions for specialised market sector, size, and business model according to Client’s specification and requirements.


As a water and wastewater treatment company committing to be environmentally friendly, we aim to minimise and/or extract value from waste streams.
