Critical path to Good Ecological Status
Starting Position (2025)
92 River Water Bodies
- 12 Good
- 80 Failing
Important: The sequence below does not imply priority or delivery order. It sets out the logical pathway by which the catchment could achieve Good Ecological Status and the contribution that each intervention is expected to make.
Step 1: Deliver Committed Wastewater Investment
South West Water has already committed to AMP8 and AMP9 investment in 21 sewage treatment works. We estimate that delivery of these schemes could result in 12 river water bodies achieving Good Ecological Status.
Remaining failing RWBs: 68
Step 2: Complete Remaining Priority Wastewater Upgrades
A minimum of 7 additional sewage treatment works are located in catchments where wastewater is the dominant pressure. Phosphate reduction at these assets is likely to be necessary to achieve Good Ecological Status.
Potential additional RWBs reaching Good: 7
Remaining failing RWBs: 61
Step 3: Resolve Suspect Fish Data
The Environment Agency has identified 9 river water bodies with suspect fish data. Based on the wider condition of these river systems, there is a realistic possibility that around 6 river water bodies could be reclassified as Good following updated monitoring.
Potential additional RWBs reaching Good: 6
Remaining failing RWBs: 55
Step 4: Restore Fish Passage
Seven river water bodies appear unlikely to achieve Good status without investment in fish passage and ecological continuity. We estimate that fish passage improvements alone could enable around 5 river water bodies to achieve Good status.
Potential additional RWBs reaching Good: 5
Remaining failing RWBs: 50
Step 5: Address Special Cases
Eight river water bodies are affected by site-specific issues such as mining impacts, heavily modified channels, flow regulation or other non-standard pressures.
We estimate that bespoke interventions alone could restore 4 river water bodies to Good status, while the remaining 4 will also require agricultural interventions.
Potential additional RWBs reaching Good: 4
Remaining failing RWBs: 46
Step 6: Improve Dairy and Beef Slurry Management
Fourteen river water body catchments have high dairy and beef cattle densities and are likely to require targeted slurry management support.
Step 7: Improve Poultry Manure Management
Ten river water body catchments have high poultry densities and are likely to require targeted manure management support.
Step 8: Ongoing Regulatory Enforcement
Targeted regulatory enforcement work focused on compliance with Farming Rules for Water will be needed in 48 river water body catchments
Step 9: Support to Improve Soil Quality and Reduce Runoff
Support programmes (advisory and funding) will be needed to improve soil quality and reduce runoff in 48 river water body catchments
Supporting Interventions
The following interventions are not generally part of the critical path, but are likely to improve outcomes and increase resilience across the catchment.
Riparian Tree Planting - phytobenthos failures appear closely linked to nutrient enrichment. Increasing riverside shading could help reduce algal growth and improve ecological condition in affected water bodies
Fish Habitat Improvement - fish passage alone may not always be sufficient to restore fish populations. Targeted habitat enhancement is likely to accelerate recovery in a number of catchments
Private Sewerage Awareness Programme - private sewerage systems are not generally the determining factor preventing Good Ecological Status in individual river water bodies. However, across the catchment they represent a significant cumulative pressure and would benefit from a targeted awareness and improvement programme
Unit Cost of Interventions
Purpose
This section provides indicative costs for the principal interventions required to deliver Good Ecological Status. Costs are intended for strategic planning purposes and represent typical interventions within a single river water body. Actual costs will vary depending on local site conditions, scale, complexity and delivery approach.
1. Investment in Sewage Treatment Works (phosphate reduction)
Intervention: reduce phosphorus and other pollutant discharges from sewage treatment works through tighter permit standards and investment in treatment infrastructure
Delivery lead: South West Water
Typical cost:
- Small works: £1m
- Medium works: £3m
- Large works: £8m+
- Average used as assumption: £3m
Funding route: water company investment (AMP programmes)
Cost confidence: medium
2. Investment in Storm Overflows
Intervention: reduce the frequency and duration of storm overflow spills through network upgrades, storage provision and operational improvements
Delivery lead: South West Water
Typical cost:
- £1m for small project
- £10m for large project
- Average used as assumption: £7m per overflow
Funding route: water company investment (AMP programmes)
Cost confidence: medium
3. Regulatory Enforcement
Intervention: Environment Agency inspections, investigation and enforcement activity focused on priority farms
Delivery lead: Environment Agency
Typical cost:
- 1 dedicated agricultural regulatory officer: £80,000 per year (fully loaded cost, not salary)
- Typical capacity: 40 farms per year

- Physical works: highly variable
- Average assumption used: £250,000 per RWB
Funding route: site-specific combination of public funding, regulatory investment, environmental grants and private finance
Cost confidence: low
10. Riparian Tree Planting
Intervention: establish riparian woodland and increase river shading to reduce algal growth, improve water temperature resilience, reduce bank erosion and support ecological recovery
Delivery lead: landowners, North Devon Biosphere Foundation (Devon Woods programme), Westcountry Rivers Trust, Devon Wildlife Trust, National Trust
Typical cost:
- 1 dedicated farm adviser: £80,000 per year (fully loaded cost, not salary)
- Typical capacity: 40 farms per year
- Advisory support: £2,000 per woodland project
- Assumption: 1 hectare of riparian woodland creation per participating landowner (projects will also likely include non riparian together with the riparian); 1 hectare of riparian woodland is broadly equivalent to 1 kilometre of planting at an average width of 10 metres along a single river bank
- Capital establishment cost: £12,000 per hectare
- Maintenance cost: £400 per hectare per year for 15 years = £6,000 per hectare
- Average assumption used: £20,000 per participating landowner (equivalent to 1 hectare of riparian woodland creation plus advisory support)
Funding route: England Woodland Creation Offer (EWCO), woodland grants, SFI/ELM schemes, water company catchment programmes, biodiversity funding and private finance
Cost confidence: medium
Note: woodland creation schemes typically provide both establishment and long-term maintenance funding. The £20,000 assumption reflects the full support package required to establish and maintain 1 hectare of riparian woodland over the initial 15-year maintenance period.
11. Fish Habitat Improvement
Intervention: improve fish populations through gravel augmentation, woody debris introduction, refuge habitat creation, bank restoration, channel diversification and targeted in-stream habitat enhancements.

- Average assumption used: £50,000 per river water body
Funding route: Environment Agency fisheries programmes, river restoration programmes, water company catchment investment, charitable trusts, environmental grants and private finance
Cost confidence: low-Medium
Note: fish habitat improvement is intended to complement fish passage improvements rather than replace them. It is most likely to be effective where barriers to movement have already been removed or mitigated.
12. Private Sewerage Awareness & Improvement Programme
Intervention: increase awareness, maintenance and compliance of private sewerage systems through targeted communications, inspections, advice and support for priority properties
Delivery lead: Local authorities, Environment Agency, catchment partnerships, NGOs and householders
Typical cost:
- Awareness campaign and communications: £2,000-£5,000 per operational catchment
- Technical advice and inspections: £250-£500 per priority property
- Improvement grants for priority properties: £2,000-£5,000 per property
- Average assumption used: £10,000 per operational catchment
Funding route: Local authorities, catchment partnerships, charitable grants, household investment and private finance.
Cost confidence: medium
Note: this intervention focuses on awareness, maintenance and targeted improvements to priority properties. It does not assume wholesale replacement of private sewerage systems across a catchment
Intervention Summary
What the analysis tells us
- The challenge is large: achieving Good Ecological Status across North Devon requires an estimated £387.9 million of intervention investment
- Most of the funding route already exists: we estimate that 95% (£368.9 million) can be delivered through existing programmes and recognised funding mechanisms
- The true funding gap is relatively small: around £18.9 million remains without an obvious delivery mechanism
- The real challenge is coordination: aligning existing funding, regulatory activity and delivery programmes with the river water bodies where they will have the greatest impact
- North Devon does not need to invent a new recovery system: much of the infrastructure, expertise, funding and delivery capacity already exists
- Success will depend on filling a small number of strategic gaps, particularly around slurry management, poultry manure, fisheries recovery and bespoke interventions for special-case river water bodies

Interventions Detail
1. Investment in STWs (phosphate reduction)
| Investment in STWs (phosphate reduction) | |
|---|---|
| Description | Reduce phosphorus and other pollutant discharges from sewage treatment works through tighter permit standards and investment in treatment infrastructure. |
| Lead delivery organisation | South West Water |
| No. of river water bodies | 13 highest priority, 27 secondary priority |
| Estimated total cost | £120m |
| Funding available | £120m (£42m already secured in AMP8 & AMP9) |
| Funding gap | £0m |
| Funding route / source | Water company investment (AMP programmes) |
| Ecological benefit | Reduce phosphorus loading from wastewater, improve phosphate and phytobenthos status. |
| Confidence in costings | Medium (£3m is a very broad average) |
Progress
- South West Water have plans to invest in sewage treatment works to reduce phosphate level in 48 river water bodies
- The funding for this is agreed in 5-year investment periods; AMP8 is 2025-2030 and is currently being delivered ; there are 5 river water bodies that will see reductions in phosphate from AMP8 investments at an estimated total cost of £15 million
- AMP9 (2030-2035) is still subject to consultation; South West Water are currently planning investment in phosphate reduction in 17 river water bodies in AMP9 at an estimated total cost of £51 million
- Having made these investments, there are 7 river water bodies that will definitely require investment in sewage treatment works to reduce phosphate levels; these should be the priority for any further changes to AMP9, and then for AMP10 (2035-2040); this would cost c.£21 million
- In addition, there are 19 river water bodies where wastewater phosphate forms part of mixed pressure signature, along with agriculture pressures. While sewage treatment works investment is necessary in these catchments, it is unlikely to be sufficient on its own to achieve Good Ecological Status and will need to be combined with agricultural interventions. Investment in these river water bodies in AMP10 (2035-204) would cost an estimated £57 million
- All funding is currently classified as available because a recognised delivery mechanism exists through successive water company investment periods (AMP8, AMP9 and AMP10). While not all funding has yet been formally approved, there is a clear and established route to securing investment through the regulated water industry planning process

2. Investment in storm overflows (reduction in spills)
| Investment in storm overflows (reduction in spills) | |
|---|---|
| Description | Reduce the frequency and duration of storm overflow discharges through investment in natural flood management measures, sewerage infrastructure and network performance. |
| Lead delivery organisation | South West Water |
| No. of river water bodies | 33 |
| Estimated total cost | £231 million |
| Funding available | £231 million |
| Funding gap | £0 |
| Funding route / source | AMP 8-10 |
| Ecological benefit | Reduced wastewater pollution from storm overflow spills, improving water quality, supporting ecological recovery, reducing public health risks associated with sewage contamination, and improving confidence in the safety and enjoyment of rivers for recreation and angling. |
| Confidence in costings | Medium |
Progress
- South West Water have plans invest in all storm overflows that are regularly spilling, with a target to bring them down to less than 12 spills per year
- These investments are prioritised across investment periods
- AMP8 (2025-2030) prioritises storm overflows impacting shellfish waters, bathing waters and ecologically sensitive stretches of river; this includes 5 river water bodies at an estimated cost of £35 million
- AMP9 (2030-2035) remains subject to consultation and regulatory approval; South West Water are currently planning storm overflow investment affecting 19 river water bodies at an estimated cost of £133 million
- The remaining storm overflows required to achieve the less-than-12-spills-per-year target would then be addressed through AMP10 (2035-2040). We currently identify 9 river water bodies with high or very high spill frequencies that should be prioritised for acceleration into AMP9 where feasible
- All funding is currently classified as available because a recognised delivery mechanism exists through successive water company investment periods (AMP8, AMP9 and AMP10). While not all funding has yet been formally approved, there is a clear and established route to securing investment through the regulated water industry planning process

3. Regulatory enforcement to drive compliance with Farming Rules for Water
| Regulatory enforcement to drive compliance with Farming Rules for Water | |
|---|---|
| Description | Environment Agency inspections, investigation and enforcement activity focused on priority farms. |
| Lead delivery organisation | Environment Agency |
| No. of river water bodies | 48 (21 priority, 27 secondary) |
| Estimated total cost | £1.3 million (equivalent to inspecting & engaging 645 farms) |
| Funding available | £1.3 million |
| Funding gap | £0 |
| Funding route / source | Included within existing statutory activity |
| Ecological benefit | Reduced nutrient, sediment and faecal pollution from agriculture through improved compliance, contributing to improved phosphate status and reduced phytobenthos failures. |
| Confidence in costings | Medium-high |
Progress
- The Environment Agency currently has 2 regulatory enforcement officers active in the North Devon Management Catchment, each with a target of inspecting and working with 40 farms per year; this level of activity was started in 2025
- We estimate that inspections and engagements at 645 farms within priority or secondary priority river water bodies will be needed to drive towards Good Ecological Status; with 2 regulatory enforcement officers and 40 farms per year, this will take c.8 years
- We would advocate for investment in a third, and potentially a fourth, regulatory enforcement officer. This would represent a relatively low-cost intervention with the potential to significantly accelerate delivery across agricultural catchments
- We have classified the funding as available because regulatory enforcement forms part of the Environment Agency's existing statutory responsibilities. The current level of resource is sufficient to deliver the intervention over time, although additional officer capacity would significantly accelerate delivery and increase the likelihood of achieving Good Ecological Status within a shorter timeframe

4. Dairy/beef cattle slurry management support
| Dairy/beef cattle slurry management support | |
|---|---|
| Description | Support farms to improve slurry handling, storage, treatment and land application. |
| Lead delivery organisation | Farmers, advisers, Environment Agency, grant programmes and private finance providers. |
| No. of river water bodies | 14 |
| Estimated total cost | £7.3 million |
| Funding available | £1.5 million |
| Funding gap | £5.8 million |
| Funding route / source | Not yet clear |
| Ecological benefit | Reduce phosphorus losses from livestock farming and improve phosphate and phytobenthos status. |
| Confidence in costings | Low-medium |
Progress
- There are generalist farm advisory programmes active across Northern Devon (Natural England, Devon Wildlife Trust, Westcountry Rivers Trust and North Devon Plus), but none are explicitly focused on beef and dairy cattle farms and slurry management. Advisory support is available, but current provision is fragmented and not aligned to the priority river water bodies identified through Catchment Catalyst
- The UK Government has previously funded slurry infrastructure improvements through schemes such as the Slurry Infrastructure Grant, providing capital support for additional slurry storage and associated infrastructure. However, the programme has operated through periodic funding rounds rather than as a permanent open scheme, creating uncertainty around future access to capital funding and making long-term planning difficult for farmers
- Additional support has historically been available through the Countryside Stewardship Capital Grant programme for some pollution reduction and water quality measures. However, access to these grants is often linked to the work of the Catchment Sensitive Farming team, whose resources are limited and currently focused on a small number of priority catchments each year. Demand for capital grants has also frequently exceeded available funding
- There is currently no dedicated North Devon programme focused specifically on slurry management within priority river water body catchments. As a result, support is fragmented across advisory, regulatory and grant-funded initiatives
- Designing and securing funding for a dedicated slurry management programme should be considered a priority. We estimate that approximately 245 priority livestock farms fall within the 14 target river water body catchments. Delivering tailored advice and infrastructure improvements across these farms is likely to require a multi-year programme combining advisory support, grant funding, farmer investment and private finance
- Based on current funding mechanisms, we estimate that approximately 20% of the required investment could potentially be met through existing grant programmes and farm co-investment, leaving a significant funding gap that would require a dedicated catchment-scale funding programme to address

5. Poultry manure management support
| Poultry manure management support | |
|---|---|
| Description | Improve the storage, transport, treatment and land application of poultry manure to reduce nutrient losses to watercourses. |
| Lead delivery organisation | Farmers, advisers, poultry integrators, Environment Agency, grant programmes and private finance providers. |
| No. of river water bodies | 10 |
| Estimated total cost | £1.9 million |
| Funding available | £0.4 million |
| Funding gap | £1.5 million |
| Funding route / source | Farmer investment, poultry supply chains, grants, water company catchment programmes and private finance. |
| Ecological benefit | Reduce phosphorus losses from poultry farming and improve phosphate and phytobenthos status. |
| Confidence in costings | Low-medium |
Progress
- There are generalist farm advisory programmes active across Northern Devon (Natural England, Devon Wildlife Trust, Westcountry Rivers Trust and North Devon Plus), but none are specifically focused on poultry manure management within poultry-intensive catchments
- Existing support is largely targeted at nutrient management and regulatory compliance rather than the systematic management of poultry manure surpluses at catchment scale. As a result, there is currently no coordinated programme addressing the movement, treatment, processing and application of poultry manure across priority river water body catchments
- Some support may be available through existing grant programmes, including Countryside Stewardship Capital Grants, Catchment Sensitive Farming support and wider pollution reduction initiatives. However, these schemes were not designed specifically to address poultry manure pressures and are unlikely to provide funding at the scale required
- Delivery is further complicated by the fact that the environmental impact of poultry enterprises is often concentrated within a relatively small number of holdings, requiring bespoke solutions rather than generic farm advice
- Designing and securing funding for a dedicated poultry manure management programme should be considered a priority. We estimate that approximately 74 priority poultry farms fall within the 10 target river water body catchments. Delivering tailored advice, nutrient planning, manure handling improvements, treatment infrastructure and manure export arrangements across these farms is likely to require a multi-year programme combining advisory support, grant funding, poultry supply-chain investment and private finance
- Based on current funding mechanisms, we estimate that approximately 20% of the required investment could potentially be met through existing grant programmes, farm investment and poultry supply-chain contributions, leaving a substantial funding gap that would require a dedicated catchment-scale programme to address

6. Soil health interventions
| Soil health interventions | |
|---|---|
| Description | Provide advisory support and funding to farms, to improve soil health and reduce runoff, through: increasing soil cover and living roots, improving crop and grassland diversity, minimising soil disturbance and compaction, improving grazing and stocking management, increasing soil organic matter, managing runoff pathways and monitoring soil condition. |
| Lead delivery organisation | Natural England, DWT, WRT, EA |
| No. of river water bodies | 48 (21 priority, 27 secondary) |
| Estimated total cost | £18.0m (equivalent to supporting 645 farms) |
| Funding available | £12.0m |
| Funding gap | £6.0m |
| Funding route / source | Farmer investment, SFI/ELM schemes, private finance |
| Ecological benefit | Less phosphorous, less sediment, improved phytobenthos and macroinvertebrate communities, enhanced fish habitat quality, and greater catchment resilience to drought and high rainfall events. Additional co-benefits include increased soil carbon, improved soil health and reduced downstream flood risk. |
| Confidence in costings | Low-medium |
Progress
- We estimate that support is required at approximately 645 farms within the 48 target river water body catchments, at a total cost of £18.0 million. Delivering soil health and runoff reduction measures across these farms would require a combination of advisory support, environmental land management payments, targeted capital grants and private finance over a number of years
- There are a range of farm advisory programmes active across Northern Devon, including support delivered by Natural England, Devon Wildlife Trust, Westcountry Rivers Trust and North Devon Plus (although some of these programmes require continuation funding). In addition, the Catchment Sensitive Farming team provides dedicated support within two priority river water body catchments each year. Together, these programmes already provide a substantial proportion of the advisory capacity required to support soil health and runoff reduction measures
- Government funding is available through the Sustainable Farming Incentive (SFI), which supports many of the measures identified within this intervention, including cover crops, herbal leys, low-input grassland, buffer strips, nutrient management and soil planning. Additional support has historically been available through the Countryside Stewardship Capital Grant programme for practical runoff reduction measures such as sediment traps, livestock management infrastructure, watercourse fencing and alternative drinking water supplies. However, access to these schemes can be constrained by advisory capacity, eligibility requirements and the fact that demand has often exceeded available funding
- In addition, there is emerging evidence of soil carbon markets providing a potential private-finance route for some farms, creating opportunities to blend public and private funding sources where improvements in soil health can be measured and verified
- The principal challenge is therefore not the absence of funding mechanisms, but ensuring that advisory support and financial incentives are targeted towards the highest-priority farms and river water bodies identified through Catchment Catalyst
- Based on current funding mechanisms, we estimate that c.66% of the £18.0 million investment requirement could potentially be met through existing Government schemes and emerging private-finance mechanisms over a 10-year period, leaving a significant but potentially bridgeable funding gap

7. Fish data
| Fish data | |
|---|---|
| Description | Collection of new fish data to target river water bodies where the Environment Agency recognises its fish data is suspect. |
| Lead delivery organisation | West Country Rivers Trust, Environment Agency |
| No. of river water bodies | 9 |
| Estimated total cost | £54,000 |
| Funding available | £0 |
| Funding gap | £54,000 |
| Funding route / source | Environment Agency monitoring programmes, catchment partnerships, fisheries programmes, charitable grants and research funding. |
| Ecological benefit | None – improved confidence in fish data. |
| Confidence in costings | High |
Progress
- The Westcountry Rivers Trust already undertakes extensive fisheries monitoring across the South West, including electrofishing surveys using methodologies similar to those employed by the Environment Agency
- However, fish classification under the Water Framework Directive is currently based on formal Environment Agency monitoring data. While fisheries data collected by third parties is routinely shared with the Environment Agency and may be used to inform wider fisheries management decisions, it is not generally relied upon directly for Water Framework Directive classification purposes
- As a result, the purpose of this intervention is not to replace statutory Environment Agency monitoring. Instead, it is to generate sufficient evidence to challenge current assumptions, identify where classifications may no longer reflect river conditions, and support the case for updated Environment Agency monitoring during the next Water Framework Directive assessment cycle
- The Environment Agency has already recognised that fish classifications may be unreliable in a number of river water bodies. We have identified nine river water bodies where suspect fish data may be contributing to current classifications and where updated evidence could materially affect ecological status assessments.
- Compared with many other restoration interventions, this represents a relatively low-cost and potentially high-impact opportunity. If updated monitoring demonstrates that fish populations are healthier than current classifications suggest, a number of river water bodies could potentially achieve Good Ecological Status without requiring additional physical restoration measures.
- There is currently no dedicated funding programme for this activity. Delivery would require a relatively modest investment through fisheries programmes, catchment partnership funding, charitable grants, research funding or direct support from the Environment Agency

| Funding route / source | Environment Agency, river restoration programmes, water company catchment investment, National Lottery, charitable trusts, environmental grants and private finance. |
| Ecological benefit | Improvement in fish populations and other benefits arising from restored ecological connectivity and flow. |
| Confidence in costings | Low-medium |
Progress
- The Westcountry Rivers Trust and Environment Agency already undertake fish passage and river restoration projects across the South West, meaning the technical expertise and delivery mechanisms are well established
- We have identified seven river water bodies where fish passage appears to be a significant constraint on achieving Good Ecological Status. However, delivery costs remain highly uncertain until individual structures have been assessed and options developed
- Experience elsewhere demonstrates that costs vary considerably depending on the size of the structure, ownership, engineering complexity and consenting requirements. Individual projects can range from relatively simple removals to multi-million-pound engineering schemes
- The immediate priority is therefore assessment, option appraisal and project development. This will create a pipeline of investable projects and improve confidence in future cost estimates
- There is currently no dedicated funding programme for these barriers. Delivery is expected to rely on a combination of Environment Agency funding, river restoration programmes, charitable grants, National Lottery funding, water company catchment investment and private finance

9. Special case interventions
| Special case interventions | |

| Description | Address localised and non-standard environmental pressures, including mining impacts, specific pollutants, low/no flow, heavily modified water bodies and other complex ecological issues. |
| Lead delivery organisation | Varies |
| No. of river water bodies | 8 |
| Estimated total cost | £2m |

| Funding gap | £2m |
| Funding route / source | Site-specific combination of public funding, regulatory investment, environmental grants and private finance. |
| Ecological benefit | Intervention specific. |
| Confidence in costings | Low |
Progress
- We have identified 8 river water bodies where failure appears to be driven by localised or non-standard pressures that do not fit within the main intervention pathways identified through Catchment Catalyst
- These include issues such as historic mining impacts, specific pollutants, low or no flow conditions, heavily modified channels and other complex ecological pressures that require bespoke assessment and response
- Unlike wastewater, agricultural runoff or fish passage interventions, there is no standard delivery model for these river water bodies. Each case requires investigation to understand the root causes of failure and identify appropriate solutions
- The immediate priority is therefore feasibility, evidence gathering and option appraisal to improve understanding of costs, benefits and delivery mechanisms
- Funding routes are also likely to vary significantly between sites and may include regulatory investment, public-sector funding, environmental grants, charitable funding and private finance, depending on the nature of the pressure being addressed
- Given the complexity and diversity of these cases, cost estimates and delivery pathways remain less certain than for other intervention areas. As a result, further investigation should be considered the first phase of delivery

Progress
- The North Devon Biosphere Foundation, through the Devon Woods programme, already has an active delivery mechanism for woodland creation across Northern Devon. This provides an established platform for identifying opportunities, engaging landowners and supporting applications for woodland grants
- Funding is available through the Forestry Commission's England Woodland Creation Offer (EWCO), which provides support for woodland establishment and long-term maintenance. As a result, unlike many other interventions, a recognised and funded delivery route already exists
- We have therefore classified the full £2.7 million investment requirement as available, as the principal funding mechanism is already in place. The key challenge is not securing grant funding but generating sufficient landowner participation and targeting woodland creation towards the highest-priority river water bodies
- The priority should be to focus woodland creation within river water bodies where riparian planting can deliver the greatest ecological benefit, including locations affected by nutrient enrichment, elevated algal growth, limited channel shading and poor habitat resilience
- Additional incentives may further increase uptake. In particular, opportunities to combine EWCO support with woodland carbon revenues, biodiversity funding and water-company catchment investment could improve the attractiveness of projects to landowners and accelerate delivery
- While some continuation funding will be required to maintain the advisory capacity provided through Devon Woods, the delivery model, funding route and implementation mechanisms are already established, making this one of the most delivery-ready interventions

11. Fish habitat improvement
| Fish habitat improvement | |
|---|---|
| Description | Improve river habitat quality for fish through restoration of spawning habitat, in-channel features, river margins and natural river processes. |
| Lead delivery organisation | West Country Rivers Trust |
| No. of river water bodies | 7 |
| Estimated total cost | £400k |
| Funding available | £0 |
| Funding gap | £400k |
| Funding route / source | Environment Agency fisheries programmes, river restoration programmes, water company catchment investment, charitable trusts, environmental grants and private finance. |
| Ecological benefit | Direct improvement in fish habitat quality, supporting increased spawning success, juvenile recruitment and population resilience. |
| Confidence in costings | Low-medium |
Progress
- The Westcountry Rivers Trust already delivers fish habitat improvement projects across Northern Devon and the wider South West, including gravel augmentation, woody debris introduction, bank restoration, channel diversification and other measures designed to improve habitat quality for salmonids and other fish species
- As a result, the technical expertise, delivery partnerships and practical methods required to implement this intervention are already well established. The challenge here is securing funding to expand activity within the six priority river water bodies
- There is currently no dedicated long-term funding programme available to deliver fish habitat improvements at scale. Delivery is therefore expected to rely on a combination of Environment Agency fisheries programmes, river restoration funding, water company catchment investment, charitable trusts, environmental grants and private finance

12. Private sewerage awareness & improvement programme
| Private sewerage awareness & improvement programme | |
|---|---|
| Description | Improve the management of private sewerage systems through awareness campaigns, advice, inspections and support for repairs and upgrades. |
| Lead delivery organisation | To be established |
| No. of river water bodies | 17 |
| Estimated total cost | £170,000 |
| Funding available | £0 |
| Funding gap | £180,000 |
| Funding route / source | Not yet clear |
| Ecological benefit | Reduce diffuse nutrient pollution from private sewerage systems and support improved phosphate status. |
| Confidence in costings | Low-medium |
Progress
- There is currently no dedicated programme or lead organisation focused on identifying and addressing private sewerage impacts within priority river water body catchments.
- We have identified 18 river water bodies where private sewerage systems may be contributing to water quality pressures. However, further investigation is likely to be required before the scale of the problem, and the most cost-effective interventions, can be fully understood
- Potential delivery partners could include local authorities, the Environment Agency, catchment partnerships, water companies and environmental NGOs. However, no delivery mechanism has yet been established
- At present there is no dedicated funding route for this intervention. Further work is required to identify potential funding sources and delivery partners, although the relatively modest scale of investment required suggests that a targeted awareness and improvement programme may be achievable through a combination of public funding, charitable grants and catchment partnership investment
- Given the relatively low cost of intervention and the potential for cumulative improvements across multiple catchments, a pilot programme focused on a small number of priority river water bodies may represent an effective first step

Community Action
Biosphere Partnership organisations are leading on many community engagement projects across the North Devon catchment. Some of these are explicitly related to water quality whereas others may focus on other aspects, such biodiversity or wellbeing, but these projects often include actions that will help improve our rivers.
The Biosphere is currently progressing a large public engagement project called Healthy Rivers. Working with the Taw & Torridge River Champions, we are linking together the existing rivers groups across North Devon, and identifying where gaps exist and creating new groups where needed. We are offering training on water testing, using similar kit to that used by Westcountry Rivers Trust, so that new Citizen Scientists can monitor their local river. The collected will be uploaded to the Smart Biosphere where it will be publicly available for analysis and download.
What can you do now to improve water quality?
- Walk your local river and report any issues. Pollution should be reported to the Environment Agency on 0800 807060
- Always bag and bin dog waste.
- Use eco cleaners around your house.
- Stop using fabric softener; generally these chemicals are not removed by treatment works.
- Create a "rain garden". By diverting downpipes onto your garden, you can slow water flow into the sewer system and reduce the risk of sewage overflows.
- Add water butts to your downpipes to reduce water usage and thereby keep more water in our rivers.
- Remove litter from rivers and beaches.
- Stop using pesticides in your garden.
- Avoid/reduce the use of flea treatments for pets.
- Support campaigns for improving water quality.
