Innovative micro-tunnelling technology to be used in St Paul’s Bay sewer infrastructure project

The sewer infrastructure in St Paul’s Bay and Kennedy Grove is set for a major upgrade, utilising a state-of-the-art trenchless technology known as ‘micro-tunnelling’.

The project, to be carried out by the Water Services Corporation (WSC) against an investment of €6.4 million, is set to vastly improve the wastewater management system in the area. 

The project was announced by Minister for the Environment, Energy and Enterprise Miriam Dalli and WSC CEO Karl Cilia during a visit in the locality, where works are set to start by the end of April.

Utilising the micro-tunnelling technique allows for the construction of a 1.9km sewer gallery without the need for extensive excavation, reducing disruption to the community and minimising environmental impact.

Minister Miriam Dalli emphasised the importance of this project, stating that “This project is needed as the population is growing in this locality and we need to ensure the proper infrastructure that can address the increasing demand. By upgrading our sewer system, we will not only improve the quality of life of our residents but also protect our environment and ensure the sustainability of our community for generations to come.”

The new sewer gallery will collect the majority of St. Paul’s Bay and Kennedy Grove’s sewerage, thereby easing the strain on the existing infrastructure. The project is divided into two lots, with a combined execution period of 50 weeks. Both lots will be worked on simultaneously, ensuring the efficient and timely completion of this much-needed upgrade.

WSC CEO Karl Cilia said that, “This project is a testament to our commitment to innovation and sustainability. By leveraging cutting-edge technology, we aim to enhance the wastewater management system, protect public health, and preserve our environment. This project is just one of many that the corporation will be embarking on in the nearby future, with similar initiatives planned for Marsa, St. Julian’s, Msida and Birżebbuġa.”

Also present for the press conference was St Paul’s Bay Mayor Alfred Grima who welcomed the project in the area, underlining that the substantial investment would be strengthening the town’s water and sewage infrastructure. “This is an investment which has been prioritised by the Water Services Corporation, and one which will be causing as little an inconvenience to residents as possible, despite the size of the project,” Mayor Alfred Grima highlighted.
