WORK begins this week on building a huge underground pipe to prevent flooding in Hambledon.
Contractors yesterday started building a mile-long pipe beneath West Street and East Street.
It will collect groundwater from the hills and drastically reduce the chances of a repeat of last year’s major flood.
The work is set to last 15 months. Road closures and a diversion route will come into force later this month.
The £4.3m scheme is being overseen by Hampshire County Council.
