Sediment management is important to water companies for operational reasons, but also to balance ecological concerns and allow regulatory compliance around these issues. Impounding structures, including those associated with water company activities, commonly alter sediment supply dynamics, which can lead to degradation of operational efficiency of assets. Sediment is a fundamental component of natural fluvial processes and impacts to sediment dynamics can have significant negative consequences for the geomorphology and ecology of a river and its anthropogenic uses.

The research has increased understanding of sediment management issues faced by the water industry and reviewed current UK guidance and regulations with respect to sediment management. Examples of good practice sediment management at impounding structures have been collated into  a comprehensive sediment management manual which consists of step-by-step guidance and 50 evidence sheets covering diverse topics from sourcing sediment for re-introduction to dealing with unforeseen problems.

Resilience – performance measures, costs and stakeholder communication

This report is a further step in the evolution of work undertaken by the water industry related to the concept of resilience. The work focusses on the service provided by the water supply and wastewater sectors and how aspects of resilience of that service could feed into Periodic Review 2019. The work also draws on the parallel work of the Water and Wastewater Resilience Action Group (WWRAG).

The report desribes different ways of looking at resilience and how resilience can be expressed in terms of Outcomes and so contributes to Ofwat's consideration of possible resilience metrics that could be used to set Performance Commitments and Outcome Delivery Incentives.

The report gives a structured and practical approach to the development of resilience metrics appropriate to a range of business purposes and technical types, with specific reference to stakeholder communication. Candidate metrics for each of the two water sector services are listed.

Resilience: Making a Business Case for PR14

Published Date: 22/04/2013

Resilience in the water industry can be defined as the ability of an asset or asset system to continue to withstand or to recover from the effects of an exceptional event such that acceptable service levels are maintained and/or restored quickly. This project aimed to supprt water companies in developing a business case for resilience at PR14 and beyond.
An extensive literature review was carried out. Natural and man-made hazards that could result in extreme risks were categorised and quantified and used to develop guidance covering: Resilience risk screening and assessment; Detailed resilience assessment; Implementation of resilience solutions.
The guidance adopts an iterative, risk-based approach to allow consistency with water company planning methodology and compliance with regulatory requirements. It includes advice on consultation with customers and stakeholders and on how resilience should be discussed.
This main report incorporates the full project report, full detail of the good practice approach and appendices including the literature review and case studies.
A summary report (13/RG/06/2) is available to provide a quick guide to the essential steps that companies might follow in developing resililence planning.
