Abstraction reform: a matter of food security

Abstraction reform: a matter of food security

Ahead of our first Water Abstraction Group workshop on 25th March, Dr Sam Hughes, Senior Water and Land Stewardship Officer, explains how growers are better working together to secure water for their crops – with major changes on the way.

The South East of England, particularly areas such as the Medway and north Kent, is a key sourcing area for fresh fruit and vegetables, grown by the horticulture sector.

Most growers rely at least in part on abstracting fixed volumes of water from the environment under a licensing system from the Environment Agency that began in the 1960s.  However, that system needs updating, especially in our region, where water scarcity has been exacerbated by the growing needs of a densely populated area and climate change. We are increasingly subject to the extremes of drought and rainfall.

Therefore the Government has brought in new legislation – namely the Environment Act to help balance the needs of the environment, which needs sufficient quantities of water retained in rivers to thrive, our human needs and those required by growers to ensure food security.

Part of the new legislation supports reform of the amount of water that growers can abstract. The changes could mean that, in the near future, growers might face cuts in the amount of water they are permitted to abstract, which could impact their business and domestic food security. The answer lies in collaboration to have a voice in regional water resource planning, which takes a holistic look at the needs of different sectors.

The rise of the WAGs – Water Abstraction Groups

Many growers of fresh fruit and vegetables including strawberries, pears, apples and peppers, are already highly innovative when it comes to water, from precision irrigation to rainwater harvesting and storage. However, some growers rely to an extent on drawing water from mains supply to supplement crop irrigation during the peak growing season. This is an expensive option and not necessarily the best for crop irrigation.

As part of a multisector group of water users with diverse needs, the voice of fresh food growers in planning is vital. That voice is stronger when growers work together rather than alone. Water Abstractor Groups – also known as WAGs – provide that much needed collective voice that speaks up for abstractor rights in regional water planning and management processes.

WAGs also mean better dialogue with regulators such as the Environment Agency or Natural England, shared resources and pooled knowledge. By raising awareness about water scarcity, climate change and drought impacts, the members of a WAG can adapt more nimbly to changes in regulations and are generally better informed of opportunities to ensure they get their fair share of water resources.

WAGs are well established in key sourcing areas such as East Anglia, where water, the environment and food security are fundamental. For example, the Broadland Agricultural Water Abstractors Group, formed in 1997, now has 170 members acting as a forum for discussion on sustainable water management and addressing issues of policy.

But is there an appetite for WAGs in the South East? How do they work?  How are they set up and what can growers in the South East expect from them?

Our fruit and vegetables require sustainable water management

Now, more than ever, is the time to work together on building sustainable water resilience for businesses that produce our food.

Through the Holistic Water for Horticulture Project (a Courtauld Water Roadmap Project), the South East Rivers Trust is collaborating with key partners to organise two workshops over 2024. These will talk with growers and farmers about the role of WAGs in a collective approach to sustainable water management for food production, in abstraction reform and in regional planning.

These workshops will be held in collaboration with the National Farmers Union (NFU), Water Resources South East, the Environment Agency, established Water Abstractor Groups (WAGs) and regional water companies.

If you are a grower, a farmer or an advisor interested in the workshop themes sign up for the first on 25th March or email holisticwaterforhorticulture@staging.southeastriverstrust.org

Helping big business tackle new water laws

In mid-2023, the South East Rivers Trust began working with Thanet Earth, the UK’s largest glasshouse grower, to help the business become even more water resilient. They also need to negotiate upcoming changes in legislation. Dr Sam Hughes, our Senior Water and Land Stewardship Officer, gives an update on our year-long project with them.

The South East of England is classed as water stressed, with demand from businesses and residents set to exceed supply by 2030. Thanet Earth, an extremely successful fresh produce business, sits in one of the driest corners of the south east – the Isle of Thanet.

Thanet Earth production

The company is already highly innovative about sourcing water for its annual production of 400 million tomatoes, 30 million cucumbers and 24 million peppers. As well as harvesting condensation and rainwater its biggest water efficiency method is a recirculation concept: all the run-off water not absorbed by the plants is collected, filtrated and re-used again and again.

This supplements some mains supply and groundwater abstraction – and the latter is a key focus of our work with the company.

Our Water and Land Stewardship team’s first report for Thanet Earth has outlined the current and future abstraction situation in the Stour catchment.

In particular, we have referenced what the implications will be from 2028, as a result of the section 88 of the Environment Act 2021, which refers specifically to water abstraction and provides for certain modifications to be implemented where change is considered necessary.

Our next steps are to facilitate a series of meetings between Thanet Earth and key water experts. The meetings aim to build relationships with organisations such as the Environment Agency to facilitate dialogue on what the Environment Act will mean for them and how much water they can abstract.

We will facilitate meetings with Southern Water, Thanet Earth’s supplier, to forge a closer working relationship and explore the potential for water sharing or trading through the platform developed by Kent County Council. With businesses facing a “use it or lose it” situation in the not too distant future when the Act is implemented, if they do not abstract all the water they are entitled to under licence, sharing with neighbouring abstractors could be a way to help meet demand.

We are also planning a workshop in early 2024 on Water Abstraction Groups to encourage working collectively for greater water resilience.

Our project with Thanet Earth is part of our Holistic Water For Horticulture  [HWH] work, an initiative that supports growers across Kent with sustainable water management.

The HWH project supports food and drink businesses through the Courtauld Commitment 2030 Water Roadmap, a voluntary commitment that supermarkets, food brands and the  businesses that supply them sign up to protect critical water resources for food production, nature and local communities.

The key target of the C2030 roadmap is that 50% of the UK’s fresh food is sourced from areas with sustainable water management.

Water and sewage plans – are companies listening?

On 2nd October water company business plans for 2025-2030 were submitted to Ofwat, who will scrutinise them to determine whether they represent value for money for water bill payers.

Earlier in the year, we asked you to have your say about water companies’ draft Water Resources Management plans. Six months on, these have been updated to final plans, alongside ‘Drainage and Wastewater Management’ plans – which focus on the dirty side of the water equation. These two plans form the basis for how water companies will manage water and sewage for the next five years and underpin the just-released business plans.

Below, we assesses the updated plans from Affinity Water, South East Water, Southern Water, SES Water and Thames Water – the companies operating across the South East Rivers Trust’s (SERT) area.

You can still have your say

We’re urging you to take further action to ensure these plans leave our rivers and the environment in a better state.

Now that plans have been submitted, Ofwat is encouraging you to continue to have your say and question the companies about the details.

This autumn, the companies will host Your Water, Your Say sessions (listed at the bottom of this blog). You will be able to speak to water company representatives, in groups and online, about their plans.

Alternatively, you can write to the Secretary of State for the Environment with your comments at water.resources@defra.gov.uk or fill in a survey about the plans, by 1st December.

What are these plans and why do we care?

Over abstraction affects rivers
Over abstraction from rivers for our water supplies affects wildlife

Water Resources Management Plans (WRMPs) set out how water of sufficient quantity and quality will be supplied to the population for the next 50 years.

This is a massive challenge in the south east, where we face a shortfall of 2.6 billion litres if nothing is done.

The WRMPs include plans to build new ‘supply schemes’ such as reservoirs, water recycling plants and water transfers from other regions, as well as ‘demand measures’ – for example by fixing leaks and encouraging wise water use – to reduce water use per person.

 

At SERT, we care about these plans because ultimately water for use in our homes and businesses is pumped from rivers and groundwater aquifers, which also feed many waterways and their habitats. As climate change bites and the population grows, demand for water is increasing; if water resources are not managed appropriately, rivers and wetland environments will suffer.

Meanwhile, Drainage and Wastewater Management Plans (DWMPs) set out how sewer and drainage systems will be upgraded to cope with population growth and peaks in surface water as rainstorms become more frequent and intense with climate change.

Clearly, the current sewage treatment system isn’t fit for purpose, with raw sewage spilling into rivers and coastal areas on a near daily basis. SERT wants the DWMPs to ensure sewage systems are upgraded at pace and measures are implemented to slow the flow of stormwater into sewers and prevent sewer overflows. This is the first time that water companies have been obliged to develop DWMPs and we welcome their existence.

Do the updated plans respond to our calls for change?

Earlier in the year, we responded to consultations on the WRMPs, and a year ago to consultations on the DWMPs.

Leakage – some improved promises made

SERT, along with many customers and stakeholders, have urged the water companies to do more to tackle leakage.

Water companies in the region are aiming for the government’s target of 50% leakage reduction by 2050, but now with additional interim targets: 20% by 2027 and 30% by 2032.

Thames Water loses around a quarter of the water it puts into supply through leakage; it is particularly encouraging to see an increase in ambition since their draft plan, which only aimed for a 16% reduction by 2030.

We challenged SES Water to roll out ‘smart’ water meters to all customers, household and non-household, by 2030.

We are delighted the company has committed to doing so. Smart meters will help to quickly identify leaks in homes, schools and other buildings.

Leaks from plumbing in homes and buildings, including ‘leaky loos’, currently account for about a third of leakage. Meters will also help customers use water more wisely.

Per person targets for water standardised

Many respondents to the WRMP consultations, including SERT, urged water companies to have stronger targets for personal consumption of water use. We said that Thames Water’s aim that people should use only 123 litres per person per day lacked ambition, particularly when other water companies in the region were going further.

Therefore we are pleased that all water company plans now meet the Government target of 110 litres per person per day – and with new interim targets.

Water use per person targets have been standardised
All water companies have adjusted ‘per person’ water use targets to align with Government aims

For non-household water users – such as businesses, schools, hospitals – water companies are now aligning with the government’s new Environment Improvement Plan target of a 15% reduction in water use by 2050. South East Water, for example, is aiming to achieve this through smart metering for business customers, alongside water efficiency audits and measures to support reductions in water use.

This is welcome given the significant number of ‘thirsty’ businesses in their area, including fruit farms and golf courses.

While it is positive that water companies have stepped up their demand management strategies in response to customer and stakeholder pressure, companies are admitting that the new targets are challenging. Meeting them will require ‘fresh thinking’ and innovative approaches and will rely heavily on the pace of government-led interventions, such as introducing water efficiency labelling on showers and toilets.

Improved positions on reducing unsustainable abstraction

Water company management plans have set targets to reduce extractions
Drought scenes like these will become common without proper plans to supply sufficient water

SERT, alongside many others, supported the most ambitious reductions in water abstraction, particularly from sensitive rivers and aquifers that feed rare chalk streams. We also challenged water companies to increase the pace of abstraction reductions and ensure a robust approach to prioritising them.

So, we are pleased to see that the regional water resources plan looks to deliver reductions more quickly and that further work on prioritisation will be carried out with stakeholders such as ourselves.

In Thames Water’s plan, while we are supportive of abstraction reductions in the Darent valley, we would like to see abstraction reductions in the upper Darent advanced more quickly – this river has been over-abstracted for decades. In the Hogsmill, an over-abstracted chalk stream in south east London, SES Water and Thames Water have been undertaking investigations to establish the effect of abstraction reductions on stream flow.

It is clear there would be a flow benefit of reducing abstraction from the Hogsmill, and we welcome Thames Water’s proposal to reduce abstraction by 10.2 megalitres per day. We urge that this is implemented as soon as possible. We recognise that the shortfall in supply needs to be met but hope that the companies will consider the extra water that would be delivered to London via the Hogsmill itself if flows were increased.

Water supply schemes – big projects going ahead, but…

Improving the size or reservoirs or building more is one solution to water management
Improving the size or reservoirs or building more is one solution to water management

While curbing leakage and encouraging wise use of water will be crucial for addressing our water scarcity challenge, the deficit cannot be met entirely with these ‘demand measures’ – water supply solutions will also be needed.

For this reason, we are supportive of reservoir schemes being progressed in the next water company business plans. These include South East Water’s Broad Oak reservoir in Kent and extending Arlington reservoir in Sussex – provided that they are built on the basis of beneficial or negligible impacts to local freshwater habitats.

The long-proposed reservoir near Abingdon in Oxfordshire (Thames Water) is also being progressed, at the larger size of 150 million cubic meters. Despite local opposition, many customers and stakeholders recognise its importance in securing the south east’s water supplies for future generations. From SERT’s perspective, it will also facilitate reducing unsustainable abstraction from sensitive freshwater habitats such as chalk stream headwaters.

We do have concerns about some of the other water resources schemes being proposed, including the Teddington Direct River Abstraction on the Thames, where there are still questions about the impact on the river ecology.

Thames Water insists that the scheme meets the ‘required level of protection set out by the Environment Agency’ and say that the company is conducting more detailed studies and working with the community to understand and address concerns.

Value of nature-based solutions has been recognised 

Nature based solutions in the landscape
Nature-based solutions help retain water in the landscape for longer and increase biodiversity

Catchment and nature-based solutions are approaches that work with the landscape to retain more water in soils and wetlands.

They allow rainwater to infiltrate into soils and aquifers, replenishing water sources rather than rainwater rushing off the land to cause pollution and flooding.

These approaches offer additional benefits, including increasing habitat for wildlife and carbon sequestration, as well as better value compared to ‘grey’, engineered solutions such as storage tanks and drains.

Encouragingly, after the draft WRMPs only contained one such catchment scheme between them – which was hugely disappointing – last-minute changes to guidance enabled 73 schemes across 24 catchments to be entered into the revised plans.

Sewer overflows action still too slow

A sewage outfall

We welcome the existence of Drainage and Wastewater Management Plans (DWMPs) for the first time.

The targets in the individual DWMPs from each company reflect what has been set out in the Government’s Storm (sewage) Overflow Reduction Plan and in the Defra Plan for Water, published in April this year.

The Government’s plans – if met – mean that 52% of such sewage overflows would be improved by 2040 and all by 2050.

We feel these timelines are too slow. We want cleaner rivers to enjoy now, not in 25 years.

These timelines are also off track to achieve the Water Framework Directive, which requires all rivers to reach Good Ecological Status by 2027 – sewage overflows currently account for 12% of rivers not achieving Good Ecological Status.

We welcome the accelerated rate of tackling sewage overflows in the Thames Water DWMP – with 51% of overflows being improved by 2035. The plan also includes upgrades to 30 sewage treatment works across the Thames Valley by 2030, and the investigation of options for a new sewage treatment plant in the London area.

Southern Water’s DWMP will reduce the use of all their 979 sewer overflows to less than 10 times per year, but only by 2050. However, by 2030 they have committed to reducing the number of spills from sewer overflows by 80%. They say they will start by tackling the overflows that release close to high priority sites, such as shellfish waters, between 2025 and 2030, and bathing sites by 2035.

We welcome the drive in the DWMPs towards nature-based solutions. Southern Water is prioritising the use of these solutions over ‘grey’, engineered solutions to address sewer overflows. There are wildlife, amenity and carbon benefits to these approaches, as well as cost savings: Thames Water says that its plan, which also prioritises nature-based solutions, is two-thirds the cost of a ‘grey-only’ plan.

Verdict

Overall, while we still think some elements of the plans could be fast-tracked, we welcome the increase in ambition since the draft plans.

The business plans amount to £96 billion of investment across England, which is desperately needed to keep our rivers clean and flowing and to ensure plentiful water supplies.

It’s important that customer money is used transparently, responsibly and cost effectively. This is why we urge water companies and government to prioritise nature-based solutions, which offer good value for money, as well as improved resilience to floods and droughts – and benefits for nature.

These should be delivered in partnership with local environmental NGOs that have the expertise and local connection to rivers.

What YOU can still do

Water companies have to demonstrate customer support for their business plans. To enhance and maintain the environmental ambition of these plans in the face of government push back, it’s important that you, as water customers, make your voice heard.

Helping the UK’s largest glasshouse food grower with water resilience

The Water and Land Stewardship Team at the South East Rivers Trust (SERT) is working directly with Thanet Earth, the largest food grower using a glasshouse in the UK, to support them on a pathway to greater water resilience.

This is part of our Holistic Water For Horticulture work, an initiative that supports growers across Kent with sustainable water management.

Thanet Earth estimates that it produces about 400 million tomatoes, 30 million cucumbers and 24 million peppers every year. To meet its water needs, the company pumps in groundwater and collects rainwater and condensation from the glasshouses (imagine a greenhouse on an industrial size). However, this is becoming increasingly unsustainable as the company grows and climate change bites.

The drought of summer 2022 was a wake-up call for many commercial food growers, who already faced unprecedented challenges in a time of environmental uncertainty and burgeoning economic constraints.

Thanet Earth from above
Thanet Earth glasshouse has its own reservoir

Extreme changes in seasonal weather patterns, water availability and rising prices for materials, fuel and other goods are just some of the factors affecting the sector as never before. At the same time, measures for food security and environmental sustainability must work hand in hand for the benefit of all.

Kent-based growers already work in an area that is classed as water-stressed, a designation that applies to all of the south east of England. In times of prolonged extreme heat and little to no rainfall such as 2022, restrictions can be applied to protect the environment and ensure that there is enough water for all.

Water is the foundation upon which horticulture businesses are built. The issue of water is particularly relevant for crops that grow under glass or plastic (protected crops), since sufficient quantities of good quality water must be used during the growing season.

Over the next year, SERT’s Water and Land Stewardship team will be investigating options to increase the water supply resilience of the Thanet Earth site. This includes measures to collect, store, abstract and share water, within the context of sustainable water management in the region.

The SERT team will help identify funding options to support the implementation of measures and facilitate contact with key stakeholders and practitioners. These include the local water company, other water abstractors and government agencies. We’ll also help navigate the changes to legislation for water abstraction resulting from the 25 Year Environment Plan and the implementation of the Environment Act 2021.

Water supply of crops at is carefully managed at Thanet Earth

Pleun van Malkenhorst, Managing Director of Rainbow UK (Thanet Earth), said: “As one of the largest local business water users, we are very aware of our responsibility to do so sustainably.  By working directly with The Water and Land Stewardship Team at the South East Rivers Trust this will help us to continually improve the way we utilise water on site.”

Dr Samantha Jane Hughes, Senior Water and Land Stewardship Officer at SERT leading on the project, said: “We are really looking forward to working with Thanet Earth over the coming year on how to improve water resilience for a business that is already highly innovative when it comes to alternative sources of water such as rainwater and even condensation harvesting.

“The challenges for this sector are real and we will have to think out of the box and consult with different specialists in order to build a resilient pathway that supports the business, helps to ensure food security and does not impact the environment.”

The HWH project supports food and drink businesses through the Courtauld Commitment 2030 Water Roadmap, a voluntary commitment that supermarkets, food brands and the  businesses that supply them sign up to protect critical water resources for food production, nature and local communities.

The key target of the C2030 roadmap is that 50% of the UK’s fresh food is sourced from areas with sustainable water management.

The HWH project works across the sector to identify site-specific measures to improve water self-sufficiency of growers and to reduce impacts caused by excess water runoff through nature-based solutions.

Keeping water in the landscape through PROWATER

As our PROWATER project comes to an end, Kathi Bauer, our Senior Natural Capital Officer, reports on the importance of working together using nature-based solutions to retain water in the landscape, protecting rivers and communities from the effects of climate change.

The results of our work, carried out over the past four years, will help retain 24 Olympic sized swimming pools worth of water in the catchment each year – and that’s just on a small section of the landscape.

Water scarcity is an issue we need to address now

Back in 2018, when PROWATER first started, a summer drought was putting pressure on water resources and nature. Then, we thought this was a timely reminder of how vulnerable our freshwater systems are to climate change and the need to address this challenge for people and wildlife.

Little did we know that, four years later, we would experience the driest July in England since 1935, with temperatures reaching 40°C for the first time. Almost the entire country had hosepipe bans imposed. Many rivers recorded the lowest flows ever seen – and it was even reported that the source of the Thames dried up.

River flows droughts Beult
River flows on the Beult at Stilebridge, at the bottom of the catchment, for five historic droughts and the year 2022. Some of the lowest flows ever were in 2022 (black line).

PROWATER – Protecting and Restoring Raw Water Sources Through Actions at the Landscape Scale – set out to demonstrate how nature-based solutions (NbS) can replenish water resources at a catchment scale. These NbS included wetland restoration and changes to rural land management.

In the four years since the project started, the South East Rivers Trust has worked with:

  • three water companies
  • 24 farmers

It has delivered:

  • 2 headwater wetland restoration sites
  • 16 hectares of improved soil management
  • supported 8.4 ha of chalk grassland and heathland restoration

Together, these measures will help retain more than 60 million litres of water (enough to fill 24 Olympic sized swimming pools) in the catchments every year through slower release to the river and improved recharge to the groundwater aquifers.

The 2022 drought proved a valuable stress test for these measures, but also brought home the crucial importance of scaling up our efforts to restore catchments in order to protect rivers, wildlife, and our own need for water.

Finding the right solutions for our catchments

As with any restoration effort, a key question was how this work could be funded. Public funding – mainly through agri-environment schemes – was set to change after Brexit, while private markets were only just starting to investigate how natural capital should sit alongside their regular balance sheets.

We worked in partnership with others to develop an evidenced base and demonstration site in the following areas

  • Friston Forest, part of the Eastbourne Chalk aquifer in the Cuckmere catchment and a focus area for project partner South East Water where chalk grassland and chalk heathland were restored
  • The Little Stour, where we supported Kent County Council and the Kentish Stour Countryside Partnership to improve soil health of farms. By doing this, we enhanced water replenishment of the chalk aquifer that feeds this chalk stream. This work included using cover and companion crops and an innovative rotational grazing trial on a stud farm.

We in particular focused on the River Beult, a tributary of the Medway, which feeds an important abstraction point supplying Bewl Water. This in turn provides water to large areas of Kent. The River Beult is a Site of Special Scientific Interest (SSSI) – the only riverine SSSI in Kent – but is heavily degraded because of historic modifications, including drainage and dredging. Less than 5% of its area remains as wetland habitat – an important natural feature that would have been historically much more common.

Prowater Beult infographic
The resilience of water supply in the Beult catchment and beyond is affected by a number of factors, including the presence and condition of habitats like wetlands across the catchment.

Working together to demonstrate how nature-based solutions can be delivered

Using mapping methods developed in PROWATER, we were able to target locations of potential headwater wetland areas, which, once restored, would help the river hold on to water for longer over the course of a year. Kent Wildlife Trust’s Upper Beult Farm Cluster officer helped us contact relevant landowners, leading us to visit Moat Farm, in the headwaters of the catchment, and Pullen Barn Farm, at the start of the High Halden tributary to the Upper Beult. On Pullen Barn Farm, we worked with owner Hugh Richards to trial introducing more species-rich pastures in his livestock system, as reported on a previous blog.

Moat Farm proved to be the perfect demonstration site for a new approach to restoration, focusing on process-based interventions with natural materials from the site. Landowners Mike and Jan Bax were crucial enablers, sharing our vision for the site: to demonstrate how wetland and stream restoration could look in the Upper Beult and make it a viable option for farmers and landowners.

The multi-year nature of the project allowed us to understand the opportunities on the site and build a strong relationship with Mike and Jan, and also the wider farmer cluster, facilitated by the welcoming partnership approach Kent Wildlife Trust took.

Watch our video of work at Moat Farm 

At Streetend Wood, one of two wetland restoration sites on Moat Farm, work started in February 2021. We took down some trees, before bird nesting season, to use as material for delivery of the main works in July. In November 2021, the site started wetting up before entering a long, dry period. However, throughout the drought, vegetation stayed lush and some standing water was present until September 2022, providing refuge for wildlife.

From demonstration site to catchment-scale restoration

While we are really proud of what we have delivered here, we know it is nowhere near enough. Our catchment-focused natural capital mapping, building on the WaterSystem Maps developed by the University of Antwerp, has helped us identify 5,000 ha of potential wetland habitats in headwaters and along the stream network in the Beult alone. If we really want to make a difference to our rivers, then we urgently need to grab hold of these opportunities.

So, how do we make this happen?

The answer, really, is simple: money. Most landowners will not be willing to engage with environmental schemes that have a detrimental impact on their business. While there are a number of positive, valuable options available under existing and new stewardship schemes that support farming with nature, we must go further than cover crops and two metre buffer strips.

We want to deliver on the vision of the Beult that we built over the course of the last few years and create a wetter, wilder and more diverse landscape where the river has space to thrive. We are also helping communities by slowing release of water into the river, from which water supply for the area is abstracted.

Beult catchment
A vision of the Upper Beult catchment as we’d like to see it – a meandering river with functioning floodplains full of a mosaic of wet grassland and wetland habitats, wet woodlands in headwater catchments, thriving farms with hedgerows, ponds and healthy soils protected by vegetation all year round.

This comes with uncertainty, long-term land use change and unknown costs and activities that need to be built into schemes. We know that public funding can’t deliver on ambitions like this fully. The Green Finance Institute’s Finance Gap for Nature Report estimated that in order to deliver on the targets set by government, for example, we have a gap of £8bn funding committed to reach clean water-related targets alone.

Pilots show value for further funding

Our PROWATER Test & Trial, a sub-project of PROWATER delivered as part of Defra’s work to investigate how future government funded agri-environment schemes can support landscape-scale nature recovery, looked at how we could set payment rates that worked for farmers, and combine private funding (such as from water companies) with public money.

One barrier is the way that water company funding is regulated and its five-year cycle, among other issues. On a regional scale, for example, very few nature-based and catchment options have made it into the regional water resource plan. This is partly because of how difficult it is to model and quantify the cost-benefits of NbS on water supply.

Key to unlocking this will be piloting schemes at a larger scale and developing a shared ambition and understanding of drivers and barriers within the water industry. Then, using these schemes to develop new approaches to assessing, valuing, and integrating nature-based and catchment options into water company business plans.

Prowater workshop
Workshops helped bring together different water companies, regulators, conservation organisations and landowners.

In the Beult, we are now building on our work in PROWATER through a Natural Environment Investment Readiness Fund as well as a partnership with Southern Water and the Upper Beult Farmer Cluster, funded through Southern Water’s Environmental Improvement Fund.

The future: Co-designing landscape-scale schemes

Building on the work at Moat Farm, we are working with nearby landowners to co-develop a plan to restore and protect 18ha of riparian and headwater wetlands along 2.5km of the Upper Beult.

Further afield, across other catchments in the south east, we are using the mapping developed as part of PROWATER to understand the natural assets in the catchment, how they contribute to resilient water supply, and where opportunities are for restoration. Developing this with water company partners (Southern Water and Affinity Water), we are building a shared evidence base of these habitat features and why they are important to protect. This will help us – and them – make decisions about how and where to invest funding and to understand the scale of investment needed and impact possible.

A crucial component is developing payment schemes for landowners that reflect the benefit they are providing to the water company and enable us to deliver value for money to both. There are a lot of challenges, but the most exciting and promising part of this project is that everyone involved sees the opportunity it offers and treats it as a way of learning how we can make this work – together.

PROWATER was funded through the European Regional Development Fund, with additional support from Southern Water, South East Water, Kent County Council, Defra and the Patsy Wood Trust.

The bigger water saving picture

The recent and prolonged dry spell has brought water scarcity in the UK into sharp focus. Several water companies in the south of England have triggered restrictions, including hosepipe bans.

On 12th August the Environment Agency declared drought in eight out of 14 water areas. Unfortunately, this is likely to be the future. We can’t just pray for rain. We need to regenerate river catchments and plan for the climate crisis. 

Robyn Shaw, Assistant Education and Engagement Officer at the South East Rivers Trust, looks at the factors around water scarcity and introduces our Water Saving Tips page, which emphasises that the issue is one we must all take responsibility for and think about all year round.

Water, water everywhere…or is it?

By 2050, the South East of England will need to find at least an additional one billion litres of water per day to meet demand in the region. That is about a fifth of the water used in the region today, and equivalent to the water use of seven million people per day.  Demand for water will exceed supply by 2030.

This is because of a combination of different factors. Some of it is because of the expected growth in population (even if personal water consumption is reduced). Some because water companies are trying to ensure that they have enough water available to continue supply even during more significant drought periods.

Finally, climate change will affect when water is available, and how much. Unsustainable abstractions need to be reduced in order to avoid our rivers and wetlands being damaged beyond repair.
