Case Study: the Petteril
What are we doing?Here in the river Petteril historic data suggested that our discharges represented 70% of the phosphorus pollution contribution to the catchment
• Data gathering and evolved modelling expertise
• Building certainty around solutions which benefit the environment and seek efficiencies for customers
How are we doing it?Extensive data collection and modelling plus working with the EA and other local partners we identified that our contribution is 30% in the catchment and in some parts as low as 7%

Revised models showed P contribution from
Calthwaite WwTW to Calthwaite Beck is c.10%compared with c.90% in the PR14 water quality
models. This has allowed for 0.5mg/l to 2mg/l with catchment interventions
River sampling in headwaters of
Blackrack Beck showed P concentrations >
4mg/l (typical of point sources rather than
diffuse)
What are the benefits?Synergies between multiple drivers across the catchment and identifying innovative solutions has yielded benefits of ~£10m in avoided Totex for customers of the North West
The proposed P solutions are also low in energy and chemical, so operationally resilient to future market fluctuations
Through the efficiencies proposed we are able to explore additional catchment interventions and benefits:‐
• Work with the Rivers trust in CalthwaiteBeck
• Protect drinking water protection zones in Bowscar
• Explore ‘slow the flow’ and surface water opportunities near Carlisle. This will also improve overflows in the area delivering shellfish waters benefit

Integrated solutions; Lessons learned
• Developing a strong and inclusive partnership is key to overlaying priorities and ideas
• However, level of engagement varies as does the length of time partners are willing to contribute
• Data quality
• Funding mechanism• Timing WINEP drivers,• Support for non‐WINEP drivers e.g. flooding
• Fantastic support to the innovative approach, however some policies and frameworks were challenging to pace and scale of ambition
• Appetite for enforcement against 3rd parties in this case was good – although is key to future opportunities

Enabling a Truly Integrated Approach
• We need to address the regulatory and enforcement uncertainty. This affects risk appetite of water companies and regulators
• Greater collaboration between regulators and water companies to combine drivers• WINEP and no‐WINEP drivers to
maximise benefits
• Greater appetite/resource for enforcement against 3rd parties – private septic tanks
8. Point of compliance In accordance with our WFD and PR14 Water Quality Planning Principles, February 2015, our permitting approach is that water quality standards should be achieved at the point of mixing. Water quality standards apply throughout waterbodies and our aim is to be endeavouring to meet good status across all waters.

Where next?
• Success in the Petteril has taken a dedicated team working in
partnership for over 2 years to develop an optimised proposal
• We are actively exploring many more opportunities across 17
catchments in the North West
• Many of these will feature in our Business Plan
• Others will evolve through AMP7 as partnerships and
opportunities develop
