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 Business Plan agreed Business Plan agreed for 2020 – 2025 for 2015 – 2020 2015 2016 2017 2018 2019 2020 Project planning for 2015/16- 2018 Draft Business plan 2020 - 2025 submitted to Ofwat 7 Thames Water 14/10/2015
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
