1) , Wetland (Pilot Scheme) • Established winter 2014 • Private agreement with landowner • Catering for 800 inhabitants • Proved the science which led to Anglian Water Ingol project • Phosphate focus

2) AWG Sponsored May 2018 • Larger ambitions - 6000 inhabitants • Ammonia focus • Great opportunity to compare and contrast • Research – micro plastics and other water-vectored substances • SIP 3 Special Investigations • Potential for NATIONAL IMPACT The eutrophication of this lake highlighted a Northrepps Wetland phosphate problem in the River Mun 2014 River Mun Catchment First steps – the Northrepps wetland • Constructed in October 2014 • 0.4 hectare site • Site size dictated by population size. • Targeting phosphate in particular

Treatment Plant Northrepps Wetland

• Fantastic community buy in – 60+ local volunteers involved in creation • Team of Riverfly volunteers monitoring invertebrate changes downstream • Wildlife watching hide set up for locals on site: kingfishers, barn owl, otters, water vole and many more already using site Performance

Northrepps Wetland River Mun All-important Science Phosphate

• Recognised, accredited water sample • University-led ecological monitoring • Research statistics taken from December 2014 - February 2018 • 50%+ REDUCTION IN PHOSPHATE INPUT TO RIVER

• Rapid change in in-stream plant community • Change in stream invertebrate diversity and abundance • Gradual improvement in lake plant community The Ingol Project

• River Ingol Anglian Water sponsored • Completed May 2018 – Larger ambitions: 6000 inhabitants – Ammonia focus – toxic – Phosphate included – Great opportunity to compare and contrast – Research – micro plastics and other water-vectored substances SIP 3 Special Investigations – Potential for NATIONAL IMPACT – Anglia water include wetlands in next AMP programme Ingol Footprint

• Population 6000 PE – 6000 Bottoms – 2000 Washing Machines

Area of Land – Required Total 2.2ha Wetland area 1.3ha Calculated on Flow Concentration of pollutants Actions Deliver The Ingol Wetland

• EA identify Ammonia Issues – EA -AWG • AWG – Look at alternative • Wetland put forward as a solution • AWG commission NRT to draw up feasibility Study • Feasibility leads to site identification of site • NRT engage in Landowner negotiations • NRT Start planning process Landowner

• Supporting landowners and farmers in profitable approaches to wetlands as part of future payments for public goods and services There are so many benefits that can be derived from wetlands and many have not yet been monetised. Value of Ecosystem Value of Natural Capital Happy Human Capital Land owner Negotiations

• Rivers Trust – Trusted Partner- Independent • Not negotiating with the Water Company • It’s not just about the money – Roll of the land agent • It gives the opportunity to discuss the environment – Roll of the lawyers – Roll of NGO – Roll Of water company legal department

– Costs met by water company or other model – Community Benefits

. Local Primary School . Local No Objections . Planting Volunteers . Positive Local Impression

. Opportunities - Bird watching - Monitoring community based - Fishing - Additional Cells - Long term - Natural Permitting

• Enhancing our knowledge of effective permitting approaches • Find Pragmatic solutions • Find Joined Up Answers WFD total catchment approach to Water Quality and Quantity- Its about the long term state of the Environment.

WE DON’T WANT TO BE in the RED !!!!! Catchment Nutrient Balancing

When used appropriately, catchment nutrient balancing has the potential to reduce cost and achieve more for water quality than conventional approaches to permitting through integrated catchment solutions which provide multiple benefits. This approach also complements our updated Catchment Permitting Principles for Scheme Consideration published in October 2018.

• This position statement sets out the principles of what the Environment Agency expects when developing catchment nutrient balancing solutions, in terms of water company environmental performance, planning, permitting and compliance.

• At this time we will only consider catchment nutrient balancing proposals as trials which will be assessed on a case by case basis.

• Lets trial the Ingol and others in Norfolk – River Total Catchment Plan – – Similar approach This is what Good Looks like and we can do this IF we work together

Integrated Constructed Wetlands = Whole Catchment Solutions Plenty to learn and explore

. Carbon balance . Function of different plant species . Optimising performance within cells . Research - Full breadth of research opportunities - Micro plastics - Pharmaceuticals - Others The Rivers Trust : A Trusted Partner

RT can be the catalyst for sustainable change - Farming - Industrial - Water Management at the Catchment Scale

We can all help each other
