The first new large-scale new water storage reservoir to be constructed within the UK in additional than three a long time has come a step nearer as Portsmouth Water handed a £167m contract to Future Water MJJV Limited to construct the Havant Thicket reservoir in southern Hampshire.
Incredibly, the reservoir could be the primary of its variety to be in-built Britain since Severn Trent opened Carsington Water in Derbyshire in 1991.
Portsmouth Water, which is creating the brand new reservoir in partnership with neighbouring Southern Water, expects the ability to open in 2029. Once accomplished, it’ll maintain roughly 8.7 billion litres of water, whereas it will likely be able to supplying as much as 21 million litres of water every day.
It might be one mile from east to west and half a mile from north to south. Future Water MJJV Limited is a three way partnership between the civil engineering contractors Mackley and Jones Bros.
Portsmouth Water additionally handed a £41m contract to Ireland’s Ward & Burke Construction to finish a brand new pipeline operating to and from the reservoir.
Bob Taylor, the chief government of Portsmouth Water, stated: “This is a major milestone for the Havant Thicket Reservoir project, and we are delighted to have these two exceptional contractors delivering the scheme.
“We stay up for working carefully with each corporations to progress and full this environmentally led mission on time and inside finances.
“This includes honouring our commitment to leave a really positive legacy by creating opportunities for local employment and skills development through the reservoir scheme.”
The UK’s controversial first use of water recycling expertise
The scheme has not been with out controversy.
One concern amongst some residents has been that establishing the brand new reservoir will contain the flooding of land and its subsequent loss – it’s being constructed on a 160-hectare grassland website owned by Portsmouth Water for the reason that mid-Nineteen Sixties – and the widespread felling of historical woodland bushes.
Perhaps the larger concern, although, has been unhappiness that the reservoir might be partly full of handled wastewater combined with water from underground springs.
Alex Rennie, the chief of Havant Borough Council, wrote to Southern Water final yr claiming that the usage of recycled water – within the first use of such expertise within the UK – had not been made clear within the define planning software.
Councillor Rennie wrote: “The council fully recognises the importance of addressing the significant and urgent need to address Hampshire’s water shortfall and welcomes the efforts that are being made by Southern Water to address this.
“However, we’ve critical issues referring to the usage of recycled remedy wastewater as a brand new water supply to top-up the Havant Thicket reservoir and we’re against any such use.”
Southern, whose customers will pay for the reservoir via their drinking water bills over a lengthy period of time, has said the water recycling technology is used safely in parched parts of the world including Australia, Singapore and California.
It has insisted that growing demand due to the increased population in its region, along with different rain patterns, makes the new facility essential – while using recycled wastewater would also help protect environmentally sensitive chalk streams.
The local controversy underlines the difficulty involved in building reservoirs.
30 new reservoirs wanted
An estimated 30 new reservoirs are wanted throughout the nation to safeguard water provides in coming years as a result of each inhabitants shifts, declining rainfall ranges and the rising incidence of droughts.
The National Infrastructure Commission has advised that, within the absence of recent reservoirs being constructed, there could possibly be a capability hole within the UK of as much as 4 billion litres of water – the equal of twenty-two million full bathtub tubs – per day by 2050.
But acquiring planning permission for such websites will be each costly and time-consuming as a result of, invariably, there’s native opposition to such initiatives.
Opposition and how you can take care of it
Sir John Armitt, the chairman of the National Infrastructure Commission, has argued that ministers must again such initiatives regardless of native opposition on the idea that the social profit supplied by new reservoirs to giant numbers of individuals outweighs the inconvenience to a small variety of folks regionally affected.
He wrote in The Times final yr: “We must wake up to the impact of using more water than we can securely replenish in the face of hotter, drier weather.
“Many waterways and groundwater our bodies in England are already below strain as a result of water abstraction, presenting dangers to biodiversity.
“So in addition to reducing leaks and demand, we need to invest seriously in new reservoirs and transfer infrastructure.”
One case that Sir John has stated deserves ministerial assist is in Abingdon, Oxfordshire, the place Thames Water – which final yr needed to implement a hosepipe ban as a result of water shortages – has been attempting for practically 20 years to construct a brand new reservoir.
It has been thwarted at each flip by native opposition.

Leak prevention funding v new reservoirs
Layla Moran, the Liberal Democrat MP for Oxford West and Abingdon, has argued Thames ought to be doing extra to forestall leaks earlier than it builds new reservoirs.
Critics of the water business additionally argue that the business ought to have sought to take a position prior to now in new reservoirs.
It has been advised by some that, after privatisation in 1989, the business sought to maximise monetary returns by patching up current belongings reasonably than constructing new ones.
But that must be balanced in opposition to Ofwat, the business regulator, usually discouraging such funding by making it a higher precedence to maintain family water payments low.
The business additionally argues that, since privatisation, it has invested some £160bn – greater than may have been put in had the business remained below state possession – on decreasing leaks and bettering environmental requirements – a precedence that has assumed rising significance in recent times.
It can also be truthful to say that the business is haunted by previous errors.
In 1975, when the business was nonetheless nationalised, the previous Northumbrian Water Authority started work on the Kielder dam and reservoir at big expense. But the rise in demand for water that it was constructed to satisfy by no means materialised – and the mission grew to become a white elephant.
As the previous couple of a long time have seen huge steps made on decreasing leakage, extra metering and, maybe most significantly, extra environment friendly use of water in home equipment like dishwashers and washing machines, opponents of recent reservoirs query whether or not there actually might be such a requirement for extra of them in future.
That is clearly not the view of the National Infrastructure Commission. If it will get its approach, it won’t be one other 30 years after the Havant Thicket reservoir earlier than one other such facility is constructed.
