How much will be paid
£62 per square metre.
Where to use this item
Available for Mid Tier and Higher Tier
- in areas targeted for the reduction of water pollution from agriculture
- with support from a Catchment Sensitive Farming (CSF) officer
This item can be used for roofing a sprayer washdown area but only where a bunded concrete pad is being used and all pesticide washings drain to a holding tank (sump), without an associated drive-over biobed.
Where this item cannot be used
- to cover a livestock housing unit
- to cover a biobed
- to repair or replace existing roofing
- to cover concrete funded under RP15 Concrete yard renewal or concrete funded under a current Catchment Sensitive Farming agreement
- without relevant advice or consents from the Environment Agency or Local Planning Authority
How this item will benefit the environment
This item will provide new roofing to reduce water pollution by preventing rainfall from getting into:
- sprayer washdown areas
- manure storage areas
- livestock gathering areas
- slurry and silage stores
- build a roof structure impermeable to rainwater
- install guttering and drains to direct roof water to a clean water drain
- make sure that drainage works meet any building and local authority requirements
- meet the requirements of the silage, slurry and agricultural fuel oil (SSAFO) regulations 2010
- meet relevant British Standards - examine copies of the most up-to-date standards for guidance
Agreement holders will need to keep the following records and supply them on request:
- any consents or permissions connected with the work
- receipted invoices, or bank statements where a receipted invoice is unavailable
- please see the record keeping and inspection requirements as set out in the Mid Tier manual for more detail
Agreement holders will need to keep the following records and supply them with the claim:
- photographs of the completed work
Applicants will have to send the following with their application:
- a copy of any advice, permit or consent received from the EA or the Local Planning Authority
- photographs of the existing site
- written support from a CSF officer
Before applying, applicants must seek advice from:
- the Environment Agency to check what is required as new and significantly altered stores may have to meet the silage, slurry and agricultural fuel oil (SSAFO) regulations 2010
- the local planning authority, to check whether planning permission is required to carry out the planned works
Advice and suggestions for how to carry out this item
The following section gives advice on carrying out this item successfully but does not form part of the requirements for this item.
How to get more detailed advice
Further design advice, such as an infrastructure audit, slurry and manure handling plan, or pesticide handling report, may be available from CSF.
How to separate clean and dirty water
Foul or dirty water should not be permitted to contaminate clean waste. Plan how to manage any additional runoff from the impermeable roofed area. The restructuring of clean and dirty drains may be required, or additional works such as:
- cross drains
- catch pits
- sleeping policemen
Make sure channels and pipes meet the relevant regulations
Any foul or dirty water (including slurry or manure residues), and any associated channels and pipes, should meet the SSAFO regulations. Channels and pipes should have a minimum design life of 20 years (with maintenance).
What this item can be used to cover
This item should be used within existing yard areas that lie between or immediately adjacent to existing infrastructure.
This item can cover:
- manure stores (proof will be needed that a pollution problem exists)
- yards where animals are handled, feed, drink or exercise
- slurry and silage stores (make sure the existing floors, walls and effluent collection are not a pollution risk - contact the EA for advice)
- silage self-feeding sites
It can be used over pesticide sprayer or applicator loading and washdown areas, providing:
- the roof covers the bunded wash-down area and the drain to the holding tank
- there is a minimum 1m overhang on each side
- the bunded area is a minimum of the sprayer transport width (with the booms folded) plus 2m, and the sprayer length plus 1.5m
- the foundations and structural supports are secure and do not breach the bund, so that no pesticide washings can escape
Side walls and shades can also be built with the roof, though only at the applicant’s own expense and as long as it does not breach any consents or permits.
More information about separating clean and dirty water is available from the Rivers Trust.
More information about pesticide handling areas and biobeds, including sizing and volume calculations, is available from the Voluntary Initiative.
Catchment Sensitive Farming (CSF) operates in parts of the country where there are water quality issues linked to farming. The scheme provides farmers with free advice and training. See guidance for further information on CSF support.
