Summary of the contracting process

Natural England procured environmental restoration works at Canada Farm Meadows, part of Shapwick Heath Site of Special Scientific Interest in Somerset. The project covers four culverts and 700 metres of ditch across 10.6 hectares of floodplain grazing marsh on deep peat. The purpose is to restore year-round water movement, improve wet grassland and breeding-wader habitat, and reduce peat oxidation and carbon dioxide emissions. The works include removing and replacing four failed culverts so cattle and agricultural machinery can cross the ditches, removing woody vegetation, excavating and disposing of silt, and disposing of vegetation matter. Delivery must account for peat soils, wetland conditions, protected species where applicable, livestock and environmental controls. The main procurement category is civil engineering and environmental restoration works, including culvert construction.

This below-threshold procurement was an open competition and is now complete. The quotation deadline was 17:00 on 23 June 2026, with electronic submission not allowed. The estimated value was £49,550 excluding VAT (£59,460 including VAT). Natural England awarded the work to John Porter on 1 July 2026 for £48,400 excluding VAT (£58,080 including VAT). The active contract was signed on 1 July 2026 and runs from 1 July to 31 October 2026. There was one lot, assessed using the requirements and criteria in the Request for Quotation. Participation was reserved for small and medium-sized voluntary, community and social enterprises, with the lot identified as suitable for SMEs. The contract covers the same culvert installation and ditch restoration works described above.

This procurement demonstrates demand from Natural England for contractors able to deliver practical wetland and floodplain restoration in a protected nature site. A credible future supplier would need experience with culvert installation, ditch restoration, silt and vegetation clearance, and construction around livestock, agricultural machinery and watercourses. It would also need to work safely and effectively on deep peat and wetland ground, protect habitats and species, manage environmental constraints, and leave structures dry during construction, stable, and stock-proof on completion. Relevant capability includes installing twin-walled plastic pipes with galvanised steel motorway-barrier headwalls, compacting clean crushed stone, removing woody growth and disposing of excavated material. The requirement suits an SME or eligible voluntary, community or social enterprise with suitable site-management capacity and environmental works experience.

Notice Information

Notice Title

Canada Farm Meadows Rewetting

Notice Description

Canada Farm Meadows are part of Shapwick Heath SSSI. They are an area of species-rich floodplain meadows on deep peat. It is designated for its species-rich grassland, breeding waders, and ditch fauna and flora. The ditches are in Unfavourable Condition as they are dry throughout the year except during winter flooding. They have become isolated from the rest of the catchment as they no longer convey water because they are heavily silted and in parts covered in scrub; water control structures no longer function due to lack of management. This inability to convey water into this site during the spring and summer months causes the deep peat soils (averaging 2.00 meters) to dry out, oxidise and release carbon, increasing atmospheric CO2 levels and contributing to climate change. Restoring the Canada Farm Meadow ditches and replacing defunct culverts will allow water to reach throughout the site all year round. This site will become wetter benefiting wet grassland species and breeding waders, and the high ground-water table will create more favourable anaerobic conditions for peat soils to reduce oxidisation rates and CO2 emissions. This scheme shall contribute to government targets to reduce CO2 emissions from peat and improve habitat conditions for the biodiversity of this wetland landscape. Requirement Replace four defunct culverts and restore 700 metres of ditches across 10.6 hectares of floodplain grazing marsh on deep peat soils. Culverts are to allow cattle and agricultural machinery to cross ditches. Replacing Culverts * Working method to follow: Somerset IDB Gateway Construction Culvert Sequence Guide - using Galvanised Steel Motorway Barrier Headwalls * Somerset Internal Drainage Board Consent has been granted provided compliance with the following Culvert Details: a. Depth of existing channel: 900mm b. Rigid twin-walled plastic pipe: 600mm diameter, 6000mm length c. Back fill material: Clean crushed locally sourced quarried natural stone compacted with road-roller d. Cover to over top of pipe: 400mm depth e. Ditch width: 2700mm * Dry working area * Solid, stable structures upon completion * Stock-proof upon completion Restoring Ditches * Woody vegetation removal * Silt removal and disposal * Disposal of vegetation matter General Considerations * Working on peat soils * Working within wetland * Working within Shapwick Heath Site of Special Scientific Interest * Protected species - where applicable * Additional Environmental Considerations * Livestock The main outputs for this project will be: 1. Installation of 4x culverts. 2. Restore 700-meter ditch system
