FOG Desludging


Fat, oil and grease (FOG) is a byproduct of food preparation and cooking such as food waste, cooking oil and baked food, to name a few. FOG is identified as one of the factors that contributes to sewer blockages and water pollution. Improper management of FOG leads to clogged sewer lines, causing the sewage to overflow onto the ground, or into buildings, waterways and rivers.

Our sewer pipelines have been plagued numerous times with improper FOG disposal. When raw FOG enters into the sewer lines, it coats the interior surface of the pipes. Over a period of time, the accumulation of FOG restricts the flow of wastewater through the sewer. Eventually, the FOG will clog the sewer lines and this will cause sewage overflowing. IWK had attended to affected sites numerously to remove the accumulated FOG, as it is the most common problem in blockage of sewer lines and water pollution.

As such, Indah Water Konsortium (IWK) Sdn Bhd expanded its desludging service to include desludging of FOG trap - as to address the most common problem in blockage of sewer lines and water pollution. The expansion into this sector by the national sewerage company is to minimise the possibilities of illegal discharge and dumping of FOG in order to reduce the source of pollution, following significance improvement in the quality of river during the previous Movement Control Order (MCO).

IWK also provides end-to-end FOG trap desludging service, ensuring that all FOG will be treated according to the environmental standards. This will not only provide industries and commercial premises value for money, but also in playing our part in preserving the environment and moving towards a more sustainable future.

IWK seeks the cooperation of all food & beverage outlets, restaurants, and malls to be responsible in managing the disposal of their FOG. Collected FOG has the potential to be converted into environmentally friendly biodiesel fuel which serves as an alternative fuel produced from renewable resources.
