WATCH: New €27.5 Million Tunnel Set To Improve Malta's Water Quality

It will also save hundreds of tonnes of CO2 emissions

The Water Services Corporation has signed two major contracts for the digging and construction of a 9.5km tunnel from the Pembroke Reverse Osmosis plant to the Ta’ Qali Group of Reservoirs. This project is set to improve the overall water quality in many parts of Malta and improve operational efficiency and environmental sustainability.

This is another project forming part of the Water Services Corporation's ‘Net Zero Impact Utility’ project. The two signed contracts signify an investment of €27.5 million.

"This challenging project will ensure better quality water across Malta and a significantly improved environmental performance, implying crucial savings in electricity as well as hundreds of tonnes of CO2 per annum," said WSC CEO Richard Bilocca.

The tender for the tunnel digging was awarded to Bonnici Bros. Services Ltd. for €19.3 million

The tunnel will link the WSC's largest Reverse Osmosis plant in Pembroke to the Ta’ Qali Group of reservoirs via large diameter mains in the most efficient way. This will ensure that all the blending potential of the Reverse Osmosis water is exploited and pumping energy reduced to the barest minimum, thereby giving optimal environmental performance.

The water transferred from the Pembroke Reverse Osmosis plant will be mixed with groundwater at the Ta’ Qali Group of reservoirs, sampled and finally treated to ensure the best quality blend.

The pipes in question will be a first for Malta

The tender for the supply of large diameter glass fibre reinforced plastic (GRP) pipes to be laid inside the tunnel was awarded to the Turkish company Superlit Boru Sanayi A.S. for the value of €8.2 million.

One of these mains will also be used to supply high quality blended water to the central part of the island through a centralised hub feeding mainly via gravity. This in full respect of the project’s net zero impact aim through which better service, efficiency and environmental performance will be guaranteed.

One pipe will comprise an 8km stretch of 1.2m diameter pipe. Each pipe segment is 6m in length and weighs around 1,500kg. Another main stretching 250m at 1m width will be laid and an 80cm wide pipe will be laid across a 6 km stretch. In total, around 3,000 tonnes of pipework and fittings will be laid in the tunnel.
