Anglian Water begins work on £40m Boston pipeline
Work has started on a 39.2-mile (63km) pipeline which will carry drinking water across Lincolnshire.
Anglian Water said the £40m project would supply water from Covenham reservoir near Louth to Boston.
The company said the scheme was necessary in order to provide a secure supply for the town's growing population.
The first phase of the project will see 24.9 miles (40km) of pipe laid between Covenham and Miningsby reservoir.
The remaining 13 miles (21km) of pipe from Miningsby to Boston will be installed in 2013.
A spokesman for Anglian Water said: "When fully completed in two years time the pipeline will be able to carry 26 million litres of water every day."
Steve Swan, from the company's special projects team, said: "The population of Boston is expected to rise significantly over the next 25 years and that will put pressure on existing supplies.
"This pipeline is our response - it is also a major investment in Lincolnshire and its future," he said.
