River Tone, Parrett and Yeo Phosphorus Reduction Scheme

We are working with farmers to reduce phosphorus (P) run-off from farmyards, tracks and fields by three tonnes per year by 2025.

Project background

Wessex Water is working with farmers in sub-catchments of the Rivers Tone, Parrett and Yeo to reduce phosphorus (P) run-off from farmyards, tracks and fields by three tonnes per year by 2025.

This P offsetting initiative forms part of a wider programme of water company investment where P removal is being installed at our water recycling centres (sewage treatment works) across the catchment. Please see examples of this type of investment in west Somerset and the River Isle catchment.

By 2020 this programme had already resulted in approximately 85 tonnes less P entering the Rivers Tone, Parrett and Yeo each year and by 2025 around a further 60 tonnes will have been removed in this way.

In rural catchments such as these, wastewater treatment is only one source of P to the river, with agriculture being the other main contributor. By working with farmers to reduce P loadings from agriculture, the overall improvement in river water quality will be greater than if only P loadings from wastewater treatment are reduced.

What funding is on offer?

The project launched in 2022 and includes a grant scheme offering financial support and advice to farmers for adopting practices that reduce P inputs, prevent soil erosion and buffer watercourses from P pollution. A range of measures that reduce P loss to water are available for grant funding.

Payment rates and measure specifications are as follows:

Watercourse fencing to exclude livestock

£10.00/m as a one-off payment. The replacement of existing fencing and fencing on very extensively managed grassland are not eligible. Additional payments may be available for taking intensive grassland out of production by erecting a fence further into the field. Funding contributions for installing access gates in new fences and alternative water supplies may also be available upon request. Please contact the project team for further information.

Arable reversion to fertility building legume fallow

£600/ha* per year for a 2½ to 4½ year agreement starting in either spring or autumn 2023. Establish legume mix immediately after harvest, cutting regularly in the first year and at least once between 1 March and 15 May in years two and three. You can also include grasses, such as cocksfoot, perennial ryegrass or timothy, in a seed mix to help smother blackgrass and other competitive grass weeds. The key requirements are not to use any fertiliser or manure, or to cut or graze.

* Lower payment rates apply for free-draining soils (an adviser will confirm).

Arable reversion to low/medium input grass

£500/ha* per year for a 2½ to 4½ year agreement starting in either spring or autumn 2023. Multiple cuts for hay/silage are permitted. A key requirement is not to use any P fertiliser or manure. Nitrogen (up to 100kgN/ha/yr) and potash fertiliser applications are permitted, however, no grazing is allowed, except light grazing by sheep over winter if desired.

* Lower payment rates apply for free-draining soils (an adviser will confirm).

Arable reversion to herbal ley

£500/ha* per year for a 2½ to 4½ year agreement starting in either spring or autumn 2023. Summer grazing by cattle and sheep and multiple cuts for hay/silage are permitted. Limited manure applications are permitted. Do not apply any nitrogen fertiliser. P and potash fertiliser and lime applications are permitted, but only to maintain soil P&K indices of two. Only light grazing by sheep is permitted over winter.

* Lower payment rates apply for free-draining soils (an adviser will confirm).

Grassland subsoiling to loosen compacted soil

£75/ha as a one-off payment for using a low-disturbance grassland subsoiler to loosen compacted soil to a depth of 20cm to 35cm (8” to 13”). This should reduce surface runoff through improved water infiltration. Only use in fields where a Wessex Water catchment adviser has confirmed the presence and depth of sub-surface soil compaction by digging test holes.

Habitat creation options

Expressions of interest are also encouraged in creating runoff ponds, sediment traps and constructed wetlands to treat field runoff and ditch/drain flow, cross-slope hedgerow creation and riparian tree planting. These proposals will be eligible for capital grants that cover between 50% and 100% of the upfront capital design, establishment, and construction costs. For enquiries regarding these types of measures, please contact the project team.

Cross-slope Hedgerow Creation

£25/m as a one-off payment designed to be established in areas at risk of soil erosion.

Please note, details and specs for the pond/wetland creation and tree planting measures will be accessible soon. Please contact the
project team if you have queries in the meantime.

Compatibility with other land management payment schemes

Double-funding with other Government or private sector land-management schemes (e.g. Countryside Stewardship Mid-tier, nutrient neutrality, Biodiversity Net Gain and similar actions in the 2023 Sustainable Farming Incentive) is not permitted, apart from the Basic Payment Scheme. Please contact the project team with any queries regarding what is considered double-funding as eligibility for the Wessex Water scheme will depend on what sort of land management changes the other funding scheme requires.

Funding limits and application scoring criteria

Applications will be scored and funding will be awarded based on a range of criteria, including:

  • the predicted amount of P prevented from entering watercourses by the implementation of the measure (per application and unit area/metre)
  • the likelihood of the applicant meeting scheme requirements (as set out on this project website and in the example project agreement below)
  • the location of the measure in relation to specific water recycling centres in the scheme area.

Annual funding limits per farm business for each type of measure are:

Applications for amounts greater than the above limits will be considered in certain situations where the environmental benefits (in terms of reduced phosphorus loading to watercourses) can justify the additional expenditure.

In the event of high demand for funding for certain types of measures, further limits may be placed on the amount of funding awarded per farm and funding may be awarded on a first-come-first-served basis.

Please note that the River Tone, Parrett and Yeo Phosphorus Reduction Scheme has a fixed annual budget and Wessex Water reserves the right to decline applications.

For more information and advice on the likelihood of your application being successful, please contact the project team at the earliest opportunity to avoid disappointment.
