Nutrient Neutrality -Full Feasibility Assessment of the Potential for the Development of Constructed Wetlands within Norfolk

Further feasibility work should provide the following information in report form. The work should be informed by the initial pre-feasibility report, 'Pre-Feasibility Assessment of the Potential for the Development of Constructed Wetlands' dated 03/05/2023. The report should provide the confidence to proceed to 'design and build' phases or the rationale for not proceeding with wetland implementation. Full feasibility Specification The key deliverable for this contract will be: I. Build on the 'pre-feasibility reduction figures' through identification of the possible range, ie minimum and maximum, for nutrient reduction capacity of the site, via wetland creation, for Nitrogen and Phosphorus using: a. Transfer abstraction of water from the relevant watercourse and; with generated reductions calculated using: i. One of the following methods with a supporting narrative - P-k-C* model - k-C* model - regression equation ii. Details of potential Flow - Flows of water from the relevant source - Inflow of other water sources - Variability of flow with time iii. Details of Concentration within Flow - Nitrogen and Phosphorus loads within all water sources considered - Variability of the quality with time iv. Refinement should enhance reduction calculations by ensuring the most relevant/localised data is used. Including: - A water balance calculation - Estimated sediment accumulation rates 2. Clarification of design objectives in terms of the site's capacity to generate nutrient reductions for N and P in the context of: - Define the potential biodiversity impacts of: o potential loss of ditch/stream (where relevant) o water impoundment/abstraction o water temperature impacts through wetland transfer - Carry out soil substrate investigations to determine: o potential for groundwater interaction o the extent of clay onsite o whether the wetland requires a clay or artificial liner o if soil nutrient levels pose a risk of 'treatment liability' in terms of nutrient leaching - Development of a monitoring and baselining strategy, including: o identification of suitable monitoring points at in-flow and potential out-flows o flow and nutrient concentration monitoring - Ranged cost estimates of: o implementation and construction o performance monitoring to equilibrium o annual wetland maintenance - Carry out a desk-based assessment to identify any risks that may impact design or construction of the wetland from: o archaeological areas on-site o utilities on-site - Define the potential impacts of 'urban runoff' on wetland effectiveness (where relevant) including but not limited to: o contaminate collection and discharge risk o contaminate effect on biological processes on wetland plants DESCRIPTION CONTINUES IN ADDITIONAL TEXT SECTION Additional information: 3. Feasibility Assessment including constraints and options assessment covering: - Topography - On-site Soil & Water sampling and analysis - Geology & Hydrogeology - Groundwater protection, - Hydrology & drainage - Flood risk - Protected sites & species - Land use, Historic landfill & Contaminated Land - Estimated costs of potential wetland design, construction, monitoring and maintenance The above should be influenced by the provided 'site pre-feasibility' report and be undertaken within scope of the 'Wetland Mitigation Framework' Purpose of this Contract To support the Nutrient Neutrality project's habitat delivery enabling Natural England, landowners and other interested parties to understand constraints and likely costs of progression towards the design and build phase of schemes. ----- To apply for this opportunity you must submit your quotation meeting the requirements detailed in the Request for Quotation (RFQ) attached. Your response must be sent to [email protected] by 17:00 on 20th October 2023 If you have any clarification questions linked to this opportunity or the procurement process please submit these via email to [email protected]. Please note that, unless commercially sensitive, both the question and the response will be circulated to all tenderers.

Nutrient Neutrality - Feasibility assessment for a constructed wetland located on land near Lyscombe and Highdon SSSI in the Poole Harbour catchment area in Dorset

To create a feasibility assessment for a constructed wetland located on land near Lyscombe and Highdon SSSI in the Poole Harbour catchment area in Dorset. Nature recovery is a key focus for stakeholders, therefore naturalised solutions or those in keeping with the natural landscape should be included within the optioneering process. The output for the site assessment would be a brief report to identify the opportunities for developing a treatment wetland to treat historical nutrient loads from a groundwater-fed natural spring. Key outputs would include: • a map of the holding and the area(s) of interest (including an estimation of the amount land required in hectares required to build a treatment wetland). • an options assessment of wetland types or design that identifies opportunities for the development of a treatment wetland working with natural processes to achieve nutrient reduction and habitat improvement. • a description of the potential of the site, including barriers or potential 'show-stoppers' to the development of a treatment wetland. • an initial broad assessment of the potential nutrient credit yield range and the financial cost of delivery. Including appraisal against the wetland mitigation framework confidence matrix. 1. Desk-based feasibility assessment • A desk-based feasibility assessment guided by stage 2 of the wetland framework. This assessment should review: o Topography;  o Soil; o Geology & Hydrogeology; o Groundwater protection; o Hydrology & drainage; o Flood risk; o Protected sites & species;  o Land use, Historic landfill & Contaminated Land 2. Site assessment • The pre-feasibility assessment will require a visit from a treatment wetland engineer. To provide an overview of the land and associated hydraulic pathways through the site, then focusing on the areas with the greatest potential in terms of both credit nutrient yield and any business objectives for the land. • A soil sample(s) to be taken from prospective areas identified for wetland to determine: o Potential for groundwater interaction o Whether the wetland requires a clay or artificial liner o If soil nutrient levels pose a risk of 'treatment liability' in terms of nutrient leaching • A water sample(s) to be taken from potential source of influent to the wetland to identify nutrient concentrations of Total Nitrogen and Total Phosphorus. o Water sample(s) should be analysed against the time of year, flow conditions and recent rainfall patterns for potential variability. o Identification of prospective water sampling points on-site to measure flows and loads to the wetland. DESCRIPTION CONTINUES IN 'ADDITIONAL TEXT' SECTION Additional information: DESCRIPTION CONTINUED: 3. Options assessment & nutrient credit yield • Conduct an options assessment of wetland types/design to identify opportunities for the development of a treatment wetland working with natural processes to achieve nutrient reduction and habitat improvement. Options could include, but are not limited to: o Free surface water or integrated constructed wetlands o Floating vegetation wetlands o Hybrid systems o Other approaches to river restoration (e.g., Stage zero or reconnection to floodplain) that could deliver nutrient reductions. • Within the options assessment, identify the possible range, i.e., minimum and maximum, for nutrient reduction capacity for wetland types or design proposed. o One of the following methods should be used with a supporting narrative:  P-k-C* model  k-C* model  Regression equation • Nutrient credit yield (reduction) calculations must show the input data and methodology used to reach the nutrient yield potential. The calculation(s) should be supported by detailed workings. o On-site samples should influence/support the calculations  Water sample(s) should be analysed against the time of year, flow conditions and recent rainfall patterns for potential variability.  Soil sample(s) should be analysed to confirm soil type. o Consideration of long-term water quality:  Consideration of the effects of surrounding land use change to deliver nutrient mitigation.  Consideration of the effects of changing groundwater quality. o Any uncertainties in the data or calculations should be highlighted. Suggested baseline datasets to support assessments: • BGS - Geology Viewer (bedrock and superficial geology) - https://geologyviewer.bgs.ac.uk/?_ga=2.118364809.1498923974.1682338991-1042246947.1682338991 • Risk of Flooding from Surface Water Extent: 3.3 percent annual chance Any dataset, or surrogate data used should be accompanied by a supporting rationale for their use. To apply for this opportunity you must submit your quotation meeting the requirements detailed in the Request for Quotation (RFQ) attached. Your response must be sent to [email protected] by 17:00 on 14th November 2023 If you have any clarification questions linked to this opportunity or the procurement process please submit these via email to [email protected]. Please note that, unless commercially sensitive, both the question and the response will be circulated to all tenderers.
