Marafiq is responsible for collecting and treating the sanitary and industrial wastewater from the community and industrial areas.
The total network length is approximately 690 km for sanitary and industrial wastewater. All reclaimed is collected through a pipeline network into a series of pumps and lifting stations located in the community and industrial areas. The wastewater is delivered to the two treatment plants which are the Industrial Wastewater Treatment Plant (IWTP) and Sanitary Wastewater Treatment Plant (SWTP).
Industrial Wastewater Treatment Plant (IWTP)
The plant was commissioned in 2013 and has a design capacity of 48,000 m3/day.
Sanitary Wastewater Treatment Plant (SWTP)
The plant was commissioned in 2015 and had a design capacity of 47,500 m3/day.
The treatment plants use primary, secondary, and biological treatment processes with filtration and disinfection to treat reclaimed water . Fenton treatment and Granulated Activated Carbon (GAC) are used at IWTP to ensure compliance with the regulation from the Royal Commission.
The reclaimed water produced from the industrial and sanitary treatment plants is mainly re-used as irrigation water (30,000 m3/day) and firefighting. The standard of irrigation water is maintained to meet the Royal Commission Environmental Regulation (RCER).
