£340 MILLION MEGA-LAKE RISING FROM HAMPSHIRE COUNTRYSIDE: Environment Secretary Tours UK's First New Reservoir in 30 Years

A MASSIVE man-made lake holding 8.7 BILLION litres of water is rising from the Hampshire countryside - and it's happening right here in our backyard.

Havant Thicket Reservoir isn't just another construction project. It's the first major new reservoir built in the UK for over THREE DECADES. And Environment Secretary Steve Reed has just toured the site to see progress for himself.

The scale is staggering. The cost is eye-watering. And when it's done, it'll transform water supplies for hundreds of thousands of people across Hampshire.

THE NUMBERS THAT'LL BLOW YOUR MIND

Let's start with the basics.

£340 MILLION. That's the estimated cost of this colossal project.

8.7 BILLION litres. That's how much water the reservoir will hold when complete.

21 million litres per day. That's how much drinking water it'll supply during droughts.

160 hectares. That's the size of the new wetlands and habitats being created around it.

This isn't some modest pond being dug in a field. This is infrastructure on a scale we haven't seen in this country for over 30 years.

WHY HERE? WHY NOW?

Here's the uncomfortable truth: the South East is running out of water.

England needs to find an extra FIVE BILLION litres of water per day by 2050. And more than half of that is needed right here in the South East.

Hampshire alone faces a shortfall of at least 166 million litres per day during droughts. That number is only going up.

Climate change isn't coming. It's here. Droughts are becoming more frequent. Population is growing. And the water infrastructure we've relied on for decades simply cannot cope.

"The Secretary of State has made clear that England, especially the South East, will face water shortages in the next ten years caused by severe droughts linked to climate change," Southern Water CEO Lawrence Gosden said.

Havant Thicket isn't a luxury. It's survival.

PROTECTING HAMPSHIRE'S PRECIOUS CHALK STREAMS

But here's where it gets interesting.

This reservoir isn't just about keeping taps running. It's about protecting some of the rarest habitats on the planet.

Hampshire's chalk streams are extraordinary. About 85% of the world's chalk streams are found in southern England. These fragile ecosystems support unique wildlife that exists nowhere else.

The problem? We've been taking too much water from them.

By storing surplus winter water in the reservoir, we can reduce abstraction pressures during dry periods. The chalk streams get protected. Wildlife thrives. And we still have enough water to drink.

It's the kind of win-win that rarely happens in infrastructure projects.

THE STEEL WALL THAT'S ALREADY IN PLACE

Construction isn't some distant future promise. It's happening NOW.

A massive 13-metre-high, 20-tonne steel cut-off wall has already been installed at the site. The dam and embankment works are underway. Twin pipelines - one to fill the reservoir with spring water, one to release it during droughts - have been approved and are being built.

Portsmouth Water is handling the actual construction, with Southern Water funding the project through customer bills over many years.

It's a partnership that makes sense: local expertise building local infrastructure, with costs spread fairly.

WHEN WILL IT BE READY?

Originally, the target was 2029. That's now been pushed back to the early 2030s - partly because the project is being 'future-proofed' for potential water recycling additions.

But here's the thing: they're not rushing and cutting corners. They're doing it properly.

The shared infrastructure approach could save over £100 million compared to doing things piecemeal. If future water recycling proposals get the go-ahead, the pipelines will already be in place. No additional disruption for residents. No duplicate construction.

Smart planning, for once.

THE VISITOR CENTRE AND RECREATION PLANS

And it's not just about water supply.

When complete, Havant Thicket Reservoir will become a proper leisure destination for local residents. The plans include:

- A visitor centre and café next to the water - Walking and cycling routes throughout - Bird hides and viewing platforms - Picnic and play areas - Fishing platforms - Car parking with EV charging - Links to Staunton Country Park

It's being designed as a community hub that explains how the reservoir works, celebrates Hampshire's chalk streams, and provides green space for health and wellbeing.

Imagine: a massive new outdoor destination on our doorstep, with trails, wildlife, and water views. That's what's coming.

JOBS AND EDUCATION

The benefits extend beyond recreation.

During construction and once operational, the project will create jobs in civil engineering, environmental management, visitor services, and education. Apprenticeships and work experience opportunities are being built in for local students and residents.

Schools and colleges will gain a genuine outdoor classroom, with opportunities for fieldwork in geography, science, ecology, and climate-change topics. Real-world water management infrastructure, right here in Havant.

THE WATER RECYCLING QUESTION

There's been some confusion about recycled water. Let's be clear.

The CURRENT approved plan has no element of recycled water. The reservoir will be filled with surplus spring water from Bedhampton Springs.

However, Portsmouth Water and Southern Water are exploring whether highly-treated recycled water could be added in the future to increase capacity. This would potentially provide an extra 90 million litres per day during droughts.

That proposal - the Hampshire Water Transfer and Water Recycling Project - is still going through consultation, design, funding, and regulatory stages. It's not approved. It's not happening yet. It's being explored.

If it eventually gets the green light (targeted around 2034), the infrastructure will already be in place. That's the 'future-proofing' element.

THE LOCAL IMPACT

For residents of Rowlands Castle, Havant, and surrounding areas, this is genuinely big news.

Yes, there'll be construction disruption for several years. That's unavoidable with a project of this scale.

But the long-term benefits are substantial:

- Secure water supplies for decades to come - No hosepipe bans during droughts - Protected chalk streams and improved biodiversity - A major new recreation destination - Jobs and educational opportunities - Connectivity improvements linking communities

Horndean Parish Council has been working with other parties to ensure walking and cycling connectivity from Horndean to the reservoir site. This won't be some isolated facility - it'll be integrated into the local landscape.

THE ENVIRONMENT SECRETARY'S VISIT

Steve Reed's tour of the site wasn't just a photo opportunity. The Environment Secretary is a vocal advocate for new water infrastructure, and Havant Thicket is exactly the kind of project he's been championing.

"It was fantastic to show him the progress on site and talk through our wider plans for the future," said Lawrence Gosden.

The visit signals that this project has proper government backing. It's not going to disappear into bureaucratic limbo. It's happening.

THE VERDICT

For thirty years, Britain hasn't built a major new reservoir. Three decades of population growth, climate change, and increasing pressure on water supplies - and nothing.

Now, finally, something is being done. And it's happening HERE.

Yes, £340 million is a lot of money. Yes, the early 2030s feels a long way off. Yes, there'll be disruption during construction.

But when complete, Havant Thicket Reservoir will secure water supplies for generations. It'll protect precious chalk streams. It'll create new habitats for wildlife. It'll provide recreation and education opportunities for local communities.

This is infrastructure that matters. This is planning that works. This is Havant at the centre of something genuinely important.

The mega-lake is coming. And Hampshire will be better for it.
