Too much or too little?

Planning arena

Responding to Planning Policy….

• National policy
• NPPF – consider cumulative impact
• PPG – ensure new development & infrastructure is aligned
• Development Plans
• Wycombe Local Plan
• Neighbourhood Plans

Planning arena

Responding to planning applications:

• Infrastructure – ensure alignment through phasing to avoid

issues such as

• Flooding
• Water supply constraints
• Pollution
• Drainage and Water supply infrastructure –

strategies and assessments may be required

• Amenity – for example noise, traffic should be considered
• Odour – encroaching close to proximity to sewage works or

pumping station

• Use of Grampian style planning conditions –

no development should start until…..

Business Plan

2015 2016 2017 2018 2019 2020 Business Plan agreed for 2015 – 2020 Business Plan agreed for 2020 – 2025 Draft Business plan 2020 - 2025 submitted to Ofwat Project planning for 2015/16- 2018

Delivery

Factors that influence our timescale for infrastructure delivery:

• Clarity of the development scale & impact –

housing number & location, is permission in place, where will the connections be made?

• Clarity of the cumulative impact – development s

proposed for wider catchment area

• Any potential regulatory changes E.g. consent

limit changes?

• Investing– business plan cycles, cost benefit appraisal,

requisition route available

Our 5 Year Plan

2015-2020

Infrastructure issues - Wastewater network

• Sewer flooding
• Limited hydraulic capacity
• Groundwater or surface water infiltration
• Blockages
• Network upgrades will be required
• Delivered by developer and / or Thames

Water

• Examples of solutions:
• Pumping stations, sewer upsizing, onsite

treatment

Infrastructure issues – wastewater treatment

Sewage treatment

• Sewage treated at Little Marlow and Princes

Risborough STWs

• Upgrades to STWs expected
• Delivered by Thames Water

Infrastructure issues – water resources and supply

Water resources

• Short, medium and long term proposals to ensure sufficient

water resources – e.g. leakage reduction, water conservation, new resources – provided by Thames Water Water supply

• Local network reinforcement maybe required
• Delivered by Thames Water

Key input from a planning perspective

General

• Local Plan policies that support developers considering water

and wastewater in an integrated approach to their development Wastewater treatment and water resources

• Work closely with council and developers on timing and

phasing of development Water and wastewater network

• Encourage developers to submit water and drainage

strategies with their planning application

• Use planning conditions where needed

Conclusion

• Working closely with key stakeholders
• Ensure developments do not compromise our

assets or local amenity

• Align infrastructure with new development through

the development plan led system

• Grampian conditions to be used where appropriate
