Major Upgrade at Sant’Antnin Sewage Treatment Plant Completed

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, thanks to a major upgrade completed by the Water Services Corporation (WSC). Announced by Minister for the Environment, Energy, and Regeneration of the Grand Harbour Miriam Dalli, the €7.5 million investment, 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Key upgrades include replacing outdated aeration systems with durable stainless-steel components and installing six new magnetic bearing blowers that reduce electricity consumption.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 emphasized that this upgrade is a crucial step towards sustainable development, making wastewater treatment more efficient and aligning with national goals to reduce environmental impact and support a circular economy.


WSC CEO Karl Cilia highlighted the upgraded plant as a key milestone in enhancing services, setting a new standard for water management in Malta. The project also involved installing new pipes through a micro-tunnel from Barkat to Sant’Antnin, enabling more efficient sewage transfer and the return of treated water.


The plant is also now pre-treating livestock farmyard waste, reducing the load on urban wastewater facilities and boosting New Water production for irrigation. This initiative, first 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.
