About Us

In 1993, Tomi Industrial Services was formed to process and supply sand-based filter media for water treatment plants in Malaysia.

In the year 2000, we expanded our market overseas to include Papua New Guinea, Indonesia and Singapore.

In 2011, exports constituted over 40% of our total gross revenue. One of our larger jobs was to supply filter media for 40 filters at the Johor River Water Works for the Public Utilities Board of Singapore. We were also the sole supplier of filter sand and support gravel for the Langat II water treatment plant. In July 2022, we completed delivery of filter medium for 32-filters at SSP III, Bukit Badong. We now stock the common range of polypropylene filter nozzles and ancillary products to meet your water treatment needs.

Your Guarantee of Quality

The processing and supply of filtration material remain our core business, and our products meet both the AWWA as well as the British Standards (BS) for filter Media. 

Post-Delivery Testing at your Water Treatment Site by our Q.A. Team can be arranged upon request.

Post-Delivery Tests are critical to ensure that material delivered to Site do not deviate from the specifications laid down by the Clients / Consultants, as the filter medium plays a crucial role in the production of portable water. Post-Delivery Testing safeguards the interest of the Purchaser, ensuring that value is received for payment made. Due to our stringent in-house Quality Assurance Program, we can unconditionally guarantee the quality of single bag of filter media delivered to site insofar as the original packing is intact.
