Thames Water Water Resources Work Programme 2014 - 2019 This document presents Thames Water's work programme on water resources from 2014 to 2019. A report accompanies this programme which provides summary information on each activity. The information presented in this work programme is based on the best available information, TW will endeavour to adhere to the programme however there will be changes to the programme. A number of activities are reliant on approval of funding by Ofwat as part of the Business Plan, Thames Water (TW) will review these activities following approval of the Business Plan. The external projects (Section 2) includes a number of projects, some of which are still in discussion, these projects will involve a number of organisations and will be led by UKWir or the EA and therefore the delivery is not directly in TW's control. The programme will be updated quarterly and published on TW's website www.thameswater.co.uk/wrmp. We will work with regulators and stakeholders as we progress all aspects of the work programme. A stakeholder engagement plan has been published which accompanies the programme.
