The TBM will dig around 385m of the new sewer under Meadow Lane, allowing the road to remain open during tunnelling works.
“By employing innovative trenchless pipelaying techniques, our contractor BSG can install the new larger diameter sewer without any impact to motorists or pedestrians in the Meadow Lane area of Portadown,” said NI Water.
The tunnelling works are due to be completed by the summer.
At the centre of the £7.8m network upgrade is the construction of a new wastewater pumping station which includes a 20m diameter underground storage tank capable of holding 1.5 million litres of stormwater.
NI Water said the new infrastructure would support economic growth and future development in the area and deliver important environmental benefits for the community, including reduced risk of out-of-sewer flooding and improved water quality in local watercourses through the closure of storm overflows.
