"The sewer network in Belfast is over 100 years old and has limited capacity," said Gowdy. The combined sewer overflows are discharging into the river, which defies the EU Urban Wastewater Directive. This has also led to flooding." NI Water's £100M scheme will prevent events like this occurring again, as 19 new access shafts will intercept major storm overflow and divert the water into the new tunnel.rnTo avoid infrastructure and piled foundations in the city centre, the tunnel has had to be driven up to 30m deep, making this the deepest tunnel in Belfast's history.
