Ajman Wastewater Treatment Plant

In the past, the Emirate of Ajman had no sewage treatment infrastructure. Through a combination of septic tanks and tanker transportation, wastewater was disposed of in an open lagoon, creating many environmental problems. Water is a scarce resource. Treatment, therefore, offers an alternative source that is both sustainable and economically advantageous. With the GoA, BESIX has played a pioneering role in this field. By establishing a modern sewerage system in Ajman, ASPCL has eliminated the risks to public health and environment linked to the discharge of untreated water. 

The partnership is based on a BOOT concession structure with collection risk shared between the concession company, the government and BESIX Equity Investment.

In 2016, Six Construct was rehired by ASPCL to design and build an extension to the Ajman wastewater treatment plant. Since its completion in 2018, 450 kilometres of underground sewers collect wastewater from 175,000 households and transport it via different pumping stations to the treatment plant on the outskirts of the city of Ajman. The wastewater treatment plant processes this water, but also wastewater from buildings not yet connected to the sewerage network. That wastewater is delivered to the plant by tank trucks. The wastewater treatment plant has a capacity of 140,000m³, making it the most important treatment plan in Ajman. 

The wastewater, once treated, can be reused. 40% of it is used for unrestricted irriation of all of Ajman's landscape and greenery. 10% of the water is treated to an even higher standard by SAFI, and used for commercial and industrial applications. The plant operates 24/7 with an advanced management system, including preventive maintenance.
