Clean coastal waters back to stay

Restoring the quality of bathing water along the coast of south-east Malta and complying with European wastewater directives are the two central aims in this project.

Additional tools


The investment covers the construction of a new urban wastewater treatment plant (UWWTP), a new wastewater pumping station, an upgraded pumping station and a 1 km submarine outfall, bringing benefits to locals and the many tourists visiting the island every year.

Putting a stop to waste discharge

For several years, untreated wastewater has been flowing directly into some of Malta’s coastal waters. The new infrastructure to be built will ensure that 82% of all effluent generated is treated, thus bringing Malta in line with the EU’s ‘Urban Waste Water Treatment’ regulation. The project will restore the quality of the bathing water along the 5 km coastline between Ricasoli and Marsascala. It will therefore eliminate all raw wastewater discharged into the sea, as well as bad odours and associated health risks, and increase the residential and recreational value of the north-east coastal area, in doing so boosting its tourism potential.

The facilities will serve the wastewater treatment needs of 320 000 people residing in the Southern and Northern Harbour area and the South-eastern and Western areas, as well as industry and tourists visiting these  areas. In terms of employment, 80 direct jobs will be created while the works are being carried out, 20 once the new wastewater treatment facilities will be up and running.

Modern facilities for better water control

The key components of the works are the construction of a new UWWTP at Ta' Barkat l/o Xghajra and a new wastewater pumping station at Rinella in Kalkara. The pumping station will be equipped with a stand-by generator to prevent overflows during power cuts. An existing wastewater pumping station in Xghajra will also be upgraded, while a new 1.7 km wastewater gallery from Rinella to Ta' Barkat l/o Xghajra will be constructed, delivering about 92% of the wastewater to be treated at the new UWWTP. Finally, a new submarine outfall will discharge the effluent treated at the UWWTP, as well as storm water overflows, and double up as an emergency bypass to the plant during emergency situations.

Self-generated power

A notable feature of the UWWTP is its ‘anaerobic sludge digestion’ process which is designed to generate biogas. It is expected that up to 50% of the energy requirements of the plant will be served by the methane generated during sludge digestion.
