Climate Change 

Workbook for estimating operational GHG emissions - version 15

Reference: 21/CL/01/30
ISBN: 978-1-84057-921-5
Published Date: 16/10/2021

UKWIR has developed a standardised workbook for estimating operational greenhouse gas emissions, the Carbon Accounting Workbook (CAW), to bring consistency and accuracy to the reporting process across the water industry. The workbook has been in place for over ten years and is updated annually to reflect the needs of the industry, including changes in carbon accounting practices.

This report sets out the changes that have been made in CAW 15. Some of these changes were implemented as a result of a review that was undertaken to assess the alignment of the CAW with the ISO14064 standards.

Integrating UKCP18 with UKWIR tools and guidance: Review of existing methods

Reference: 21/CL/04/19
ISBN: 978-1-84057-917-8
Published Date: 22/05/2021

This project has systematically reviewed UKWIR methods and tools in the context of climate change following the Met Office’s recent release of the latest UK climate change projections (UKCP18). This review has particularly focussed on water resources and drainage and has taken into account current usage, industry needs into the future and the potential impact of adopting the new UKCP18 projections. As part of this, comparisons between the range of UKCP18 products with those available under UKCP09 are presented and, given the broad similarities between the projected impacts, recommended that urgent action in relation to submitted plans was not required. The study’s prioritised recommendations for updates to methods and tools has also considered other ongoing complimentary research and industry studies and has identified key research gaps for the future, recognising that the water industry methods are undergoing significant evolution at this time.

Climate Change Modelling and the WRMP

Reference: 18/CL/04/16
ISBN: 1 84057 862 9
Published Date: 09/11/2018

This Guidance reviews current climate change evidence and methodologies and proposes a new approach for WRMP 2024 designed to be used with the forthcoming UKCP18 climate projections. The existing 'top-down' approach to climate change is resource intensive and has led to significant investment to understand how systems respond to different climate exposures. In advance of WRMP 2024, this project has sought to build upon this understanding and has developed a 'bottom-up' approach framed in the context of system resilience to droughts. An online tool accompanies the Guidance to enable practitioners to apply the approach to quickly evaluate new climate change evidence and identify any scenarios for subsequent analysis, where appropriate. Using ten contrasting case studies, the Guidance demonstrates how the approach and tool can be used to assess new climate change evidence in a proportionate, targeted and system specific manner and communicate the results to stakeholders.

Flow modelling of urban water distribution systems using water conservation fittings

Reference: 18/CL/12/3
ISBN: 1 84057 849 1
Published Date: 10/02/2018

The aim of this work was to assess the impact of water conserving fixtures and fittings on UK building drainage (wastewater collection) systems of up to 100mm diameter, ranging from the point where the appliance discharges into the collection drain to the connection to the common sewer.

This involved taking an inventory of water conserving devices currently available, and to quantify the effect that these could have on wastewater collection systems in terms of increased solids residence times and creation of downstream blockages caused by solid waste deposition or other flow problems.
