Climate Change 

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.

Workbook for Estimating Operational GHG Emissions 2017 - Version 12

Reference: 18/CL/01/26
ISBN: 1 84057 857 2
Published Date: 03/07/2018

UKWIR has developed a standardised workbook for estimating operational GHG emissions, the Carbon Accounting Workbook (CAW), to bring consistency and accuracy to the reporting process across the 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.

In this update of the CAW the following changes have been implemented:

  • Updated emission factors to align with the latest UK and international data,
  • Implementation of the granular functionality which allows users to separate the individual transport fuels and admin emissions across the different operations,
  • Amend the private wire methodology to allow additional flexibility.

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.

Rainfall Intensity for Sewer Design - Stage 2

Reference: 17/CL/10/17
ISBN: 1 84057 842 4
Published Date: 13/09/2017

This research and its data products make use of a new Met Office 1.5km climate length model simulation of the United Kingdom. This is important because the model can resolve convective processes that produce the heavy rain seen in all seasons which affects the functioning of urban drainage systems. The data products are optimised for use in the planning of urban drainage networks and the analysis of surface water flooding.

The two data products, aimed at urban drainage and storm water management professionals are: 

1.            Estimated changes in design storm uplifts, covering three different regions of the UK.

2.            A time series perturbation tool that allows rainfall time series to be adjusted to reflect estimated future rainfall conditions.

Estimated changes to design storms show similar or higher changes to those currently used by the water industry - this could have significant impacts on the resilience of sewer networks in the future, triggering different adaptive responses to protect customers and communities from flooding. The time series tool allows analysis of future changes to the operation of combined sewer overflows (CSOs) and wet weather loadings on treatment plants. 

Note: The software tool for this project can be downloaded from the 'Supporting Documents' CD.
