Description
The key deliverables for this contract will be: Five pre-feasibility assessments for holdings in the and Yare Wensum River catchments area of Norfolk (approximate location as per Annex 1).
1. Each pre-feasibility study will require a visit from a constructed wetland engineer, probably commencing with the landowner (or representative) providing them with an overview of the land and associated hydraulic pathways through the site, enabling them to focus on the areas with the greatest potential in terms of both credit nutrient yield and business objectives for the land. Depending on proximity to known water sampling points, it is also possible that water samples would be taken.
Suppliers interested in bidding for the work should contact Mark Jones ([email protected]) or Joe Forster ([email protected]) for further details regarding the 5 sites.
The output for each site would be a very brief report (expected max 2 to 4 sides A4) including: ⢠a map of the holding and the area(s) and areas of interest. ⢠a description of the potential of the site, including barriers or potential 'show-stoppers' to the development of a constructed wetland. ⢠an initial broad assessment of the potential nutrient credit yield range (ie the likely scale of the financial opportunity).
2. On completion of the site visits the supplier will rank the 5 sites in order of suitability in terms of both complexity/ease of delivery and likely nutrient yield.
3. Review of Constructed Wetland modelled GIS targeting data - Following the site visits we would ask the supplier to briefly review and reflect on natural England targeting data for the sites visited. - Brief report (ie 2 to 4 sides A4)
