The Sant’Antnin sewage treatment plant in the south of Malta can now treat an additional 600 cubic meters of wastewater per hour while using less energy using innovative technology, thanks to a major upgrade completed by the Water Services Corporation (WSC).
This was announced by the Minister for the Environment, Energy, and Regeneration of the Grand Harbour Miriam Dalli, who explained that this significant investment of €7.5 million, co-financed by the EU Cohesion Fund 2014–2020, marks a substantial improvement in wastewater treatment and water management across the island.
Key upgrades include replacing outdated aeration systems with durable stainless-steel components and installing six new magnetic bearing blowers that reduce electricity consumption. These changes support Malta’s sustainability goals.
Minister Dalli stated that “this upgrade is a crucial step in our commitment to sustainable development. The improvements not only make wastewater treatment more efficient but also align with our national goals to reduce our environmental impact and support a circular economy.”
WSC CEO Karl Cilia highlighted that “the upgraded Sant’Antnin plant is a key milestone in our mission to enhance our services. With increased capacity and state-of-the-art technology, we are setting a new standard for water management in Malta.”
The project also involved the installation of new pipes through a micro-tunnel from Barkat to Sant’Antnin, enabling more efficient sewage transfer to the plant and the return of treated water.
The Sant’Antnin Plant is also now pre-treating livestock farmyard waste, helping to reduce the load on urban wastewater facilities and boosting New Water production for irrigation. This initiative, initially introduced in Gozo, is now being implemented at Sant’Antnin.
WSC remains committed to efficiently managing Malta’s water resources and ensuring a sustainable future for the island.
