1/3 Of Britain's Flood Defenses Are Private; Owners Cannot Be Compelled To Fix Or Maintain Them
A third of Englands most important flood defences are in private hands, an investigation has found, with more than 1,000 found to be in a poor state and some at risk of complete performance failure. Private owners cannot be forced to make upgrades to the defences, which can involve bills of hundreds of thousands of pounds. The government admits it can only encourage third-party owners to do maintainance, though the Environment Agency can carry out emergency repairs if there is a risk to people, property or environment, and try to bill the freeholders afterwards.
Data obtained under freedom of information laws by Unearthed, the investigative arm of Greenpeace UK, and shared with the Guardian, show that privately owned assets classed as high consequence are twice as likely to be in a poor condition as those maintained by the Environment Agency, with 8% or 1,109 of private defences rated as sub-par.
The defences range from flood walls or embankments to weirs and piers, though many are outfall pipes or culverts enclosed watercourses that run underneath roads, railways or other property.
Some are owned by major landowners such as the crown estate or Network Rail. Others run under private houses and businesses, often unnoticed until something goes wrong. In 2014 a father and son in Waterlooville, Hampshire, were faced with a £150,000 bill to repair a culvert that went underneath their properties.
