The South East Rivers Trust is pleased to announce a new natural flood management (NFM) project with funding provided by London Gatwick.
The upper River Mole is characterised by its flashy nature. As a clay-based catchment, an impermeable geology, the river is prone to both flooding during wet periods and drying up during dry periods. Climate change is expected to only exacerbate these issues. The river also faces pressure from pollution and a lack of adequate habitats for river wildlife.
This project aims to address these challenges through a series of NFM measures. These techniques, including tree planting, leaky woody structures, and wetland creation, work to slow the flow of water through the landscape, increasing the its natural retention of water, to both reduce the risk of flooding downstream during times of heavy rainfall and maintain river flows during drought periods.
A key component of the project is the implementation of a “stage zero” restoration, which involves reconnecting the river’s headwaters with their floodplain. In other words, turning back the clock to a time before human intervention. This approach not only enhances natural flood protection but also improves resilience during low flow periods, reduces diffuse pollution, and creates habitats to increase biodiversity.
Dr Chris Gardner, Head of Science and Partnerships at SERT, said: “Natural flood management is a crucial technique for us at SERT, as it harnesses and restores the natural processes our rivers depend on. We’re delighted to have London Gatwick support for this project and are eager to see the positive impact we can achieve on the ground.”
The funding from London Gatwick comes from the airport’s efforts under their sustainability policy, Decade of Change, and remains focused on what matters: increasing the emphasis on people and reducing emissions. London Gatwick is working to support and invest in local communities, continue transition to net zero for Scope 1 and 2 emissions by 2030 and reduce impact on the local environment and waste.
Ian Waghorn, Principal Environmental Water Engineer at London Gatwick, said: “We are thrilled to be working with SERT, this collaboration will provide real improvements to the Upper Mole catchment. Working with our partners is just one aspect of our ambitious water targets for this decade.
“We are making significant investments in our own water systems at London Gatwick. In our first Decade of Change we reduced water consumption from 30 litres per passenger to 15, we are now aiming to halve this figure again to 7.5 litres. This will be achieved by harnessing the capabilities of our existing infrastructure to produce a non-potable water source for toilet flushing.”
The first year of the project will focus on conducting scoping work to generate feasibility studies, engaging with local landowners, and establishing baseline surveys across the sub-catchment to pave the way for delivery in future years of the collaboration. We’re excited to get to work on this project, so watch this space!
We’re calling on you to join the #VoteforRivers campaign run by the Rivers Trust in the lead-up to the General Election on Thursday 4th July.
This is your chance to use the power we have as voters to advocate for nature restoration and to take this vital opportunity to speak up for healthy rivers.
We’ve set out asks under five headings, whether you plan to seek answers from candidates who come knocking on the door, question them at local hustings or want to write to them.
You can find the candidates running in your area using The Electoral Commissionand download the letter to write to them, or have the asks handy when meeting candidates in person.
We want you to ask the new Government to:
1. Prioritise nature recovery – make nature-based solutions like trees and wetlands to improve the environment and tackle climate change as first choice, rather than relying on chemicals and concrete.
For example, we at the South East Rivers Trust have just completed Chamber Mead wetlands in Ewell, Surrey, which diverts road runoff away from the River Hogsmill. Plants being established there will also bring huge biodiversity benefits to the Hogsmill Local Nature Reserve.
We are working on restoring water voles, eels and trout via our WET Hogsmill project, we have restored a section of the River Blackwater in Hampshire and the Wandle in Morden Hall Park with woody debris and by adding gravel.
2. Improve our understanding of rivers – support better data and evidence to improve regulatory monitoring and recognise the value of citizen science alongside it.
Through our work engaging the public and encouraging them to take part in citizen science, we collect data on the health of our rivers. Examples include training volunteers to:
Discover how much misconnected plumbing is in our rivers through our Outfall Safari work
Carry out riverfly monitoring to judge the health of rivers and whether there has been pollution, by finding invertebrates
3. Support education and engagement about rivers – No one will protect what they don’t know about or understand – and what they have not experienced. So we need the Government to support education about the environment and rivers at all levels.
The South East Rivers Trust has an extensive education programme
The South East Rivers Trust has programmes supporting education of primary school children and community groups across London catchments and the River Mole.
Our events also demonstrate the value of our work through walks and talks across a wide range of topics and we take part in awareness campaigns such as London Rivers Week.
4. Make polluters pay – drive strong enforcement of those who pollute to turn the tide on the abuse of our rivers.
We have recently supported a campaign to clear Hoad’s Wood in Ashford of fly-tipping. After a petition, the Government has now issued a clean-up edict which will cost the taxpayer huge sums. Nobody has yet been traced to pay for the clean-up.
5. Manage land with water in mind – empower collaborative working that gets everyone involved in restoring our rivers.
Leaky wooden dams are a nature-based solution used by SERT on the River Beult among other places
At the South East Rivers Trust we lead several catchment partnerships across 12 river catchments. These work collaboratively with many other organisations and individuals to bring rivers back to life. They need investment and funding to do so.
Our Holistic Water for Horticulture project also works with food growers in Kent and the South East to ensure water efficiency and resilience in the process of getting food from farm to fork.
This is part of the work of our Water and Land Stewardship team, which has worked closely with farmers on the River Beult in Kent on nature-based solutions to retain water and enhance biodiversity, for the benefit of wildlife and people. We are involved in national pilots for Environmental Land Management Schemes, funded by Government, working with farms to manage land in sustainable ways.
For example, we are working with farmers and landowners and other environment NGOs on the River Darent catchment to implement a radical, large-scale approach to delivering climate benefits – starting with rivers.
Here are some questions you can ask your candidates
How will you and your party tackle all types of pollution in our rivers? Sewage is not the only issue; farming and road runoff pollution are also devastating our rivers.
Will your party boost funding for regulators and strengthen enforcement so polluters are made to pay for their pollution?
How will your party work with nature to improve river health and tackle climate change?
How will your party open up rivers and blue spaces in our towns and cities for health and wellbeing?
How will your party support farmers and businesses manage their land sustainably for water?
No matter where you live across our 12 catchments, there is a river near you. Find our river using our map, using your postcode. There a hundreds of candidates standing for constituencies from Berkshire through Hampshire, Surrey, Sussex, Kent and south London who want your vote – so press them on the hot topics!
If you are writing to your candidates, you could use or adapt the Rivers Trust’s template, by copying and pasting the information below or adding in your own asks on rivers. Don’t forget you can source candidate details via The Electoral Commission.
Dear [Candidate name],
I will be voting for rivers in the General Election on 4th July 2024 and, as a local resident and voter, need to know how you intend to stand up for our waterways.
The Rivers Trust’s State of Our Rivers Report 2024 lays bare the dire health of our waterways, which are facing devastating levels of pollution, swinging between extremes of flood and drought, and experiencing shocking drops in biodiversity:
0% of stretches of river in England are in good or high overall health.
This is not breaking news – the issues faced by our rivers have been hitting the headlines for years and causing widespread public outcry. Yet not enough is being done to restore or protect our waterways.
Healthy rivers should be a priority for the next Government. From re-wiggling rivers, restoring floodplains, and greening our urban spaces, restoring our rivers means securing community resilience, a future for wildlife, and action for climate.
This is why I am supporting The Rivers Trust’s asks for political candidates and parties:
Prioritise nature recovery – make nature-based solutions like trees and wetlands to improve the environment and tackle climate change first choice, rather than relying on chemicals and concrete.
Improve our understanding of rivers – support better data and evidence to improve regulatory monitoring and recognise the value of citizen science alongside it.
Support education about rivers – no one will understand or care about what they haven’t experienced. Outdoor learning is key to nurturing a lifelong love of rivers.
Make polluters pay – drive strong enforcement of those who pollute to turn the tide on the abuse of our rivers.
Manage land with water in mind – empower collaborative working that gets everyone involved in restoring our rivers.
Please let me know what actions you and your party intend to take to deliver the asks above and restore the health of our waterways.
I look forward to hearing from you and, if possible, please copy info@theriverstrust.org in your reply.
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
Growers are already highly inventive when it comes to watering crops. Picture by Tzeemeng Yap via Pexels
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.
Work to create a major new series of wetlands at Chamber Mead is scheduled to begin on 29th August – pushed back from 21st August – and is planned to take approximately 10 weeks.
The project, developed over several years by the South East Rivers Trust (SERT), is designed to help improve water quality along a stretch of the Hogsmill River near Ewell. The project will also help a wider range of wildlife flourish in this part of the Hogsmill Local Nature Reserve and improve the area as a place for people to enjoy.
Water quality in this section of the Hogsmill River is adversely affected by pollution from road runoff, foul sewage pipes incorrectly connected into surface water drains and discharges from the Epsom Storm Tanks.
Wetlands are a nature-based solution to improving water quality. Water that drains through them is gradually filtered by plants and captured in the soil, intercepting and treating pollution.
The shaded area shows where the Green Lanes Stream will be blocked and diverted through the wetlands
Increased plants, pollinators and other wildlife connected to the wetlands will provide an attractive addition to this popular open space, as well as providing opportunities for outdoor education.
The new wetlands will intercept water from the Green Lanes Stream, before connecting the river channel back into the Hogsmill River, downstream of the famous Stepping Stones. This will safeguard 200 metres of chalk stream from pollution, reducing the risk to health and improving the area as a community amenity.
Further downstream, the wetlands will continue to provide benefits to the Hogsmill River, which is one of about only 200 chalk streams in the world.
Supported by the Hogsmill Catchment Partnership, the project has received funding and support from The Coca-Cola Foundation, the Environment Agency, Surrey County Council, the Rivers Trust, the Zoological Society of London and Thames Water.
It is part of the wider Replenish programme in partnership with the Coca-Cola Foundation and Rivers Trust which aims to “replenish” or restore millions of litres of water in this and other local catchments, in turn improving biodiversity.
Ed Byers, Senior Project Manager at SERT, said: “We are excited to be bringing the Chamber Mead wetlands to the Hogsmill Local Nature Reserve.
“The wetlands are much needed to improve the water quality of a precious chalk stream for wildlife and for the enjoyment of the public, who have shown great support for this project.

“As well as reducing pollution, the plants chosen, such as brooklime, marsh marigold and purple loosestrife, will also act as a magnet for an abundance of wildlife and further improve this much-loved local space.”
Parking restrictions will be in place at two locations along the Green Lanes during the works, to allow site access for vehicles involved in the construction phase and to ensure public safety.
The work will also require a large number of lorry movements to remove excavated material from the site.
On World Water Day, Dr Sam Hughes highlights our Holistic Water for Horticulture project, working with growers to make the most of every drop of water in the face of a changing climate which is likely to bring more droughts.
Last summer’s brutal drought was a stark indication that we are entering a “new normal” of hotter summers, milder wet winters and more frequent extreme weather events, from dry spells to intense rainfall.
Vineyards are among large-scale crop growing that requires huge amounts of water
Climate change is real. Temperatures reached 40C for the first time in England last year. The south and east of England had the driest July on record. Rivers ran low. Wildlife, people and businesses all suffered.
The message for tackling the climate crisis from the Rivers Trust at the time was clear. We need: a faster, more coordinated government response to extreme weather impacts; investment in water infrastructure to reduce leakage; clear support and guidance on measures to reduce household consumption; and the need to build back wetter.
“For the coming year and… for the coming decade, a complete gear change is needed for how water companies and all water users, from farmers to households, think about how they use water and understand its fundamental value.”
A wet winter, comprising five consecutive months of above average rainfall, might have lulled some into a sense of security in the short term. However, the driest February for 30 years has been a rude awakening to 2023, bringing the possibility of another period of drought for a horticulture sector in crisis, in a region of the country already classed as water stressed.
Working for water resilience, food security and environment
Water is the foundation of the horticulture sector and this is keenly felt in the drier, more crowded catchments of the South East, where lots of water is needed for a long time by a lot of farms.
Precision irrigation for crops is required to ensure the best use of precious water resources
High value protected edible crops (soft fruit, tomatoes, peppers and cucumbers to name a few) require precision irrigation over a long growing season. Out in the open, newly planted fruit orchards should be irrigated to allow young trees to establish, thrive and produce crops to support and expand business.
During the 2022 drought, a lot of growers scaled back crop areas, which ultimately affects consumers through limited availability. Many supplemented irrigation with mains water, an expensive commodity that further eroded shrinking profit margins already squeezed by inflation, labour shortages, higher labour costs and inflexible supply contracts.
Is it any surprise that these circumstances have resulted in contraction across all UK food production sectors?
Innocuous terms like “scale back” and “contraction” belie the extreme hardship being felt by businesses across the sector, especially smaller ones. The vulnerability of domestic food security has been laid bare, set against a landscape of highly altered sourcing catchments unable to cope with climate change impacts. Without acting collectively in order to drive change to lessen such impacts, businesses, supply chains, communities and the natural environment will ultimately fail.
The Courtauld 2030 Water Roadmap was launched by WRAP, the Rivers Trust and the World Wildlife Fund to meet “the challenges we face in protecting critical water resources for food supply, for nature, and for local communities” in key sourcing catchments across the UK and abroad.
The Roadmap target is for 50% of the UK’s fresh food to be sourced from areas with sustainable water management by 2030.
The South East Rivers Trust (SERT) is keenly aware of the pressures the region’s horticulture sector faces to balance water resilience, food security and environmental needs while staying in business, through our work with the Holistic Water for Horticulture project (HWH), a Courtauld 2030 Water Roadmap project. This promotes a collective approach to water and land stewardship.
The answer to being able to respond to the impact of dry spells lies in how we capture, retain and use water from our wet periods.
The pathway to water resilience is clear:
we need to build back better and wetter
it is better to work together and proactively to reap bigger water resilience benefits
Helping landowners avoid drought
HWH uses remote data to map and identify areas of present and future water risk in the South East. This high level approach is vital for targeting engagement in high risk areas, to raise awareness of the challenges that growers and neighbouring landowners might face if droughts became a “business as usual” scenario.
HWH staff make site visits to discuss water challenges and potential site-tailored solutions that can, in some cases, bring multiple benefits.
Winter and high flows from rivers and rainfall from rooftops and polytunnels should be captured and stored for irrigation. Currently, rainwater from buildings and polytunnels can be harvested without a water abstraction licence, reducing dependence on expensive mains and diversifying water resources that support business resilience and growth.
Still a relatively new concept, water trading and sharing between water abstractors across a given area will result in a more dynamic water management landscape.
Nature-based solutions such as wetlands, scrapes, planting native flowers, shrubs and trees in areas that are prone to flooding can provide alternative sources of income (carbon credits, biodiversity net gain, stewardship schemes) to growers alongside cropping areas.
Wetlands and scrapes provide advantages to land owners
These measures benefit both nature and neighbours by slowing the flow from extreme rainfall events, mitigating flood and reducing soil erosion and damage to property.
Elsewhere across SERT’s work, we work to retain water in the landscape through projects such as PROWATER, one of 10 pilots supported by the Interreg 2 Seas European Regional Development Fund.
Working together instead of in isolation to address the many challenges that face the sector packs more of a punch. Farm clusters, producer organisations, cooperatives and abstractor groups can be powerful lobbies that share information and drive change across the sector.
These are the motors of change – for water resource management and large-scale delivery of measures, such as Landscape Recovery projects through Environmental Land Management Schemes (ELMS), that benefit growers.
By joining forces with environmental experts at SERT through projects like HWH and PROWATER, these powerful groups can identify, develop and deliver solutions and make connections with different water users and stakeholders across the catchment prepared to invest in measures and innovation that benefit them too.

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 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.
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.
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.
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.
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 creation of the Chamber Mead Wetlands took another big step forward when planning permission for the scheme was granted by Epsom & Ewell Borough Council’s planning committee.
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.
The South East Rivers Trust has been working with Sutton Council to deliver a SuDS in Schools project in Carshalton. Delivering a sustainable drainage systems (SuDS) project has been a new and valuable experience for the Trust.
Timing could not have been better for this SuDS project. Along with all the extreme weather events around the world that have been in the news, closer to home flash flooding has hit the headlines. Not only does this demonstrate the urgent need to address surface water flooding, but it has brought the issue to the public’s attention. It is the perfect chance to capitalise on the growing awareness of climate change and interest in environmental issues to get SuDS on the public agenda.
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.
The weather could not have been better for our planting day at Sutton Council’s Denmark Road Offices, writes Charlene Duncan. This planting day was organised to enable staff members to contribute to the new rain garden. Thanks to the hard work of everyone who came out, the rain garden is now complete!
Nearly 30 members of staff volunteered their time to transform the area in front of the building. It was a great chance for staff to meet people from other departments and to socialise with colleagues. Staff members gave what time they could, from 20 minutes to more than three hours! Every contribution was greatly appreciated.
This rain garden is part of our SuDS in Sutton’s Schools project. It demonstrates sustainable drainage systems (SuDS) to the schools involved in the project and the wider community. SuDS are measures that divert water from the drains to reduce flood risk and improve the quality of water flowing into our rivers.
By waiting until the autumn to plant up the rain garden, we have increased the new plants’ chances of survival. Planting during this summer’s drought would have meant the plants required a lot of watering. While a bit of watering is still necessary for the newly planted garden, once established, the water from the offices’ downpipes will be all that is needed.
So, a massive thank you to all volunteers who gave up their time. And, an extra thank you for those of you who could not give your time but offered moral support and encouragement on the day. The garden is looking lovely and it’s all down to you.
