UKWIR’s Source Apportionment GIS Model (SAGIS): Research, Planning and Management (20/WW/02/11)

This project has enhanced the SAGIS-SIMCAT system through the development of new tools, methodologies, and intelligence that promote novel applications of SAGIS-SIMCAT to address key water industry challenges. Specifically, this project has enhanced the SAGIS-SIMCAT Decision Support Tool so that it can simultaneously evaluate the efficacy of measures to control inputs from both point and diffuse sources, thereby supporting catchment-based discharge permitting. This project has also scoped the development of a methodology for using SAGIS-SIMCAT to plan around the potential impacts to water quality arising from climate change, and the inclusion of Mains Water Leakage as an additional sector within SAGIS-SIMCAT. The project has served as a multi-stakeholder forum that has facilitated the dissemination, discussion and exchange of SAGIS-SIMCAT relevant knowledge and ideas.

How do we halve our freshwater abstractions sustainably by 2050?: Research review and gap analysis (20/WR/02/13)

This report provides an initial roadmap, and an integrated portfolio of research projects. Together, these chart a programme of research to support the UK and Ireland water industry to deliver upon the UKWIR Board’s aspiration to halve freshwater abstraction sustainably by 2050. The assessments and recommendations presented in the report constitute the tangible outcomes from a relatively short research review and gap analysis project, as part of its ‘Big Questions’ (BQ) programme of strategic research. Ultimately, this report marks the start of a journey towards meeting the aspiration, and as such, the roadmap and supporting material are designed to be live, and reviewed over time. The main report (Part A), which contains the roadmap linked to 5 key Outcomes, is supported by summary project definitions (Part B), and a summary of the reviews and surveys completed as part of the project (Part C).

Energy from Sewers (19/SW/03/1)

The opportunity for heat recovery from sewers and other forms of energy generation was investigated and a selection tool produced to identify heat recovery opportunities and support water utilities in developing clear business cases.

The literature review identified the scale of energy recovery technologies available to water services utilities.

Risks from blockages caused by heat exchanger or turbine heat recovery in the sewerage system were identified as were potential risks to wastewater nitrification (unless heat is taken from treated effluent).

The legal conclusion reached is that wastewater may be classified as waste, therefore permits may be required. 

Heat recovery from wastewater can make a significant contribution to the reduction of the carbon footprints in water utility service providers. The scale and opportunity for energy recovery from sewers is dependent on local conditions.

Achieving 100% compliance with drinking water standards at point of use by 2050 - Intensifying Natural Processes (19/DW/13/4)

A review of innovative technologies for improving reservoir water quality was carried out. Six technology categories were shortlisted as having the greatest potential to be implemented in UK reservoirs and contribute to achieving 100% compliance with drinking water standards by 2050.

The six shortlisted technologies have been assessed against a range of criteria and a fact file was developed for each technology, assessing it against a range of criteria, highlighting case studies where relevant and suggesting next steps towards implementation. A roadmap was also produced for each technology, outlining the potential timeline to implementation.

One technological solution in particular, “Intelligent Reservoir Management”, was highlighted as having the most potential for development, and it is recommended that the water industry focusses its efforts in this direction, developing monitoring, data analytics and modelling tools to improve understanding of reservoir dynamics and enable efficient water quality management.

Incidence and Causes of Repeat Bursts at Old Repairs (19/WM/08/71)

Analysis was undertaken at a national level to examine the proportion of mains bursts that are caused by failures of previous repairs, and how these vary between pipe materials and UK water companies.

Bursts identified as such were analysed to determine the likely cause of the failure; whether this was due to issues present at the time of the initial repair (e.g. poor workmanship), or to deterioration of the repair materials used.

Focusing on issues identified in the analysis, consolidated guidance has been prepared for maintenance operatives carrying out mains repairs in order to minimise the risk of future repeat failure.
