The mains pipe is situated in central London, stretching from Kings Cross through to Angel.
The £20 million project work to future-proof water supply in the capital will take place over three years. Engineers will be working to upgrade 1.2 miles of ageing Victorian pipes, which supply water to around 7,000 properties each day.
Much of London’s trunk main network was built in the early 19th century. The new pipeline will improve infrastructure, bringing it up to date for the 21st century and help the company meet the growing demand for water. The project will also play a crucial role in reducing leaks and bursts across London’s busy streets with work spanning from Pentonville Road (West and East) through to Myddleton Passage.
Jaymin Patel, Head of Programme Delivery, Thames Water, said:
“We’re on a mission to drive down leakage, which is why we’re investing to upgrade our ageing Victorian pipes. The work on Pentonville Road is essential and will ensure we continue to deliver a safe and secure water supply to Londoners.”
Thames Water will be working in phases from February 2024 through to 2026 - techniques the water company will be using to complete the project include drain relining, sliplining, CCTV and open-cut method. The company will only be using open-cut where necessary, to excavate ground to install new pipework.
