This project has delivered an upgraded and enhanced version of SAGIS that will enable its continued use for investment planning, river basin management and novel research applications into the foreseeable future. The legacy VBA code has been migrated to the Python and C# programming languages and the host GIS platform upgraded from ArcMap 10.2 to ArcGIS Pro 2.3. The potential risks arising from the deprecation of VBA from the ArcMap platform have been removed. The code has also been transitioned into a formal professional software development environment following a standardised development approach, with key functional elements developed as modular components. Geoprocessing logging available in ArcGIS Pro provides modellers with direct information on the status of data processing tasks and support with process failure diagnosis. The new version represents a substantial and unprecedented technological leap and opens up the possibility of new and previously unconsidered development applications.

Managing and removing surface water from sewers offers a number of operational benefits. Using different types of sustainable interventions can create substantial wider community benefits.

There is an increasing appetite across the industry to consider and deliver such interventions to help manage a range of drivers. However, this appetite is not matched by an in depth understanding of the factors that make surface water removal options more cost beneficial than traditional engineering solutions.

This UKWIR project led by Stantec, CIRIA and Anthony McCloy Associates helps to develop that understanding through:

• providing examples of surface water removal projects from the UK and Ireland and globally
• identifying the factors which make surface water management solutions successful
• understanding some of the UK and Ireland legislation that effects the delivery of surface water interventions
• developing a decision support tool to help those undertaking surface water removal projects in making better decisions

A significant number of water companies have started using Trunk Main Flow Monitoring Zones (also known as Water Balance Zones) to locate areas with leakage or unaccounted for water on trunk mains. Data from these zones help direct leakage detection and consumption recovery efforts.

While some companies are at the maturity stage in their use of Trunk Main Flow Monitoring Zones (FMZs) others are just starting on the journey. There has been no best practice or standard for the development or use of FMZs to date. Creating and maintaining a successful FMZ requires a high amount of effort, investment, time and energy. With future industry’s challenge to reduce leakage and UKWIR’s big question on zero leakage by 2050, a best practice guide for FMZs is needed and gaps in the knowledge and technology for managing trunk mains should be identified.

This interactive pdf provides a quick and easy guide to establishing the approach and the factors which should be considered. It is an overview and anyone who requires more detail should consult the full report (20/WM/08/74).

The Chemical Investigations Programme (CIP) was established by UKWIR in response to emerging legislation on surface water quality. The first phase provided an overview of the occurrence, behaviour and management of trace contaminants in wastewater. This second phase aims to identify sites at which action might need to be taken and to act as a basis for proposed solutions that are effective, proportional to the Water Industry contribution to contamination, and demonstrably justifiable down to a detailed local level. The outputs are published in four volumes (available separately) as follows:

• Volume 1 Part 2 (2015-2020) Monitoring of Sewage Effluents, Surface Waters and Sewage Sludge - Review of Programme Results and Conclusions. This volume replaces the interim (Part 1) monitoring report which was published in 2018 (Report Ref. No. 18/EQ/01/12). A copy of the Part 1 report will be provided with the Part 2 report.

• Volume 2 Monitoring of Substances of Emerging Concern, Report Ref. No. 18/EQ/01/13

• Volume 3 Wastewater Treatment Technology Trials, Report Ref. No. 18/EQ/01/14  

• Volume 4 Catchment Investigations, Report Ref. No. 18/EQ/01/15

These publications document CIP findings and will form the basis of future policy on the control of chemicals in the water environment

The document builds on the UKWIR project: 15/WM/08/55 Leakage Upstream of District Meters, where FMZ’s are mentioned, but details on operational management of them is not and provides a detailed review of the approach as well as detailed guidance on how to establish them.
