The WRSE’s “From Source to Tap: The south east strategy for water

This document showcases the ground-breaking collaboration and technical work to develop an affordable, sustainable and resilient regional strategy for water – one that delivers for customers, society and the environment. Much of the south east region is officially designated as being in serious water stress. It’s also a region where there are potentially greater pressures and challenges than those faced by other regions in the UK – more people in expanding towns and cities; relatively low rainfall but higher water use by people; and environmental pressures to keep more water in its natural home e.g. our rivers, rare chalk

The State of the Environment: Water Resources

The Environment Agency has published this document, published in May 2018 provides an overview of England’s water resources in 2018. It presents information on trends in effective rainfall, river flows, groundwater levels, water available for abstraction, wetland extent and condition, lakes and ponds. Current and future pressures are also considered.

The National Infrastruture Commission’s national needs assessment for water resources

The National Infrastructure Commission has released its assessment on the water infrastructure needs of the nation: Preparing for a drier future: England’s water infrastructure needs.   It raises awareness of the potential interruption to water supply and sets out a range of measures which it believes government, water companies and the regulator should take to increase investment in supply infrastructure and encourage more efficient use of water.  As the cost of responding to a severe drought in the UK would likely run into tens of billions of pounds, the case for a pro-active approach to improving our long-term resilience to drought is more than compelling.  The recommended measures include:

  • Ofwat should launch a competitive process by end of 2019 so at least 1,300 Ml/day is provided through (i) a national water network and (ii) additional supply infrastructure by the 2030s
  • Defra should set a target to halve leakage by 2050, with Ofwat
  • Defra should enable compulsory metering beyond water stressed areas by the 2030s

The State of the Environment: Water Quality

The Environment Agency has published this document, published in February 2018 provides an assessment of water quality in England. It presents information on water quality status and trends and discusses current and future pressures.

Defra’s A Green Future: Our 25 Year Plan to Improve the Environment

This publication is a government policy paper which sets out goals for improving the environment, within a generation. It details how those in government will work with communities and business to do this.

The goal of clean and plentiful water is an integral part of the 25-year plan. Alongside the plan, three technical annexes have been published.

The Plan sits alongside two other important government strategies: the Industrial Strategy and the Clean Growth Strategy.

The Government’s Strategic Priorities for Ofwat

The statement sets out the government’s priorities for Ofwat’s regulation of the water sector in England.

The strategic policy statement came into force on 22 November 2017. This replaces the previous SPS which was published in March 2013.

Water Abstraction Plan 2017

The html documents published on the .gov website set out what the government is doing to reform the management of water abstraction. The abstraction plan document summarises all the changes that are planned. It should be read alongside the more detailed documents covering environment, catchment focus and abstraction licensing service. The timeline is available as a pdf document.

Enabling Resilience in the Water Sector

This document, produced by Defra in March 2016 sets out how Defra intends to enhance the policy framework to secure the long-term resilience of the water sector, helping to deliver a cleaner, healthier environment, benefiting people and the economy.

This is part of a much broader programme of work to adapt to the changing climate. In 2017 a UK Climate Change Risk Assessment was published to make sure that essential services and infrastructure (including water supplies) are ready to cope with potential changes.

Improving Resilience in the Water Sector

Written in 2015, this advice report sets out information to support Defra in delivering the Water White Paper commitments related to assessing future needs for water resilience and associated strategic water infrastructure. The review is focussed on supply pressures associated with severe and extreme droughts, although it does note some non-drought hazards.

Water Resources Long Term Planning Framework

This report, published in July 2016, was commissioned by Water UK after the government asked water companies in 2015 to look at the long term resilience of water resources in England and Wales. It presents the results of research into drought risk carried out by independent consultants and peer reviewed by leading experts in water resources, climate change and environmental management. The report breaks new ground by deploying new modelling techniques and by looking 50 years ahead across the whole of England and Wales.

WRMP19 Methods – Risk Based Planning

Water resources management plans are increasingly being developed using more risk-based approaches. These will allow practitioners to better understand the current and future drought risks that they face, and create stronger links between WRMPs and drought plans.

UKWIR has published guidance on new methods and techniques that can be used for decision making in water resource planning.

Water Resources Planning Guidelines

The water resource planning guidelines issued in May 2016, issued by the Environment Agency and Natural Resources Wales in combination with Defra, the Welsh Government and Ofwat.

Guiding Principles for Water Resources Planning

This document, produced by Defra in May 2016 is aimed at water companies operating wholly or mainly in England. It explains the key policy priorities the government expects water resources management plans to address.

Managing Water Abstraction

The latest climate change predictions show that pressure on water resources is likely to increase in the future. This edition of Managing Water Abstraction (2016) sets out how the Environment Agency manage water resources in England. It explains the technical, legal and policy requirements behind the abstraction licensing strategies.

Adapting to Climate Change; UK Climate Projections

The UK Climate Projections 2009 (UKCP09) are an important step forward in improving understanding of our complex climate. There are assumptions and uncertainties in any work of this kind, but these Projections represent strong and credible climate science. They begin to quantify the uncertainties we face and so will help us to understand the risks that lie ahead.
