SAGIS model update tool to support modelling for PR24

Reference: 21/WW/02/14
ISBN: 978-1-84057-923-9
Published Date: 07/11/2021

SAGIS is a GIS-based decision support system for management of water quality at the river basin scale. To support modelling for PR24, a complementary tool has been developed to enable efficient updates to the SAGIS regional models from large national datasets of flow and water quality.

The tool is for users of SAGIS v4 (ArcGIS Pro version) and is an AddIn for ArcGIS Pro. It introduces standardisation of modelling inputs and automation of the workflow, which in turn significantly reduces the time and cost of updates and increases confidence in the quality of outputs.

This report covers the methods used in generation of the summary statistics for SAGIS and a novel approach to assessing the quality of the data inputs. The user manual for the tool is included and accompanied by a step-by-step tutorial and in depth documentation on the handling of the data.

Antimicrobial Resistance - Literature Review

Reference: 21/EQ/01/21
ISBN: 978-1-84057-919-2
Published Date: 29/09/2021

Antimicrobial resistance (AMR) is a key global health challenge, with a predicted death toll of 10 million annually by 2050. The objective of this report was to clarify existing knowledge related to antimicrobial resistance in wastewater, sewage sludge, drinking water and the environment, and to prioritise actions and further research. A systematic literature search was carried out. AMR in water, wastewater and biosolids presents a potential public health risk, although direct evidence for the quantification of this risk is limited, and studies attempting to quantify this risk should be prioritised. Overall, wastewater treatment results in a substantial reduction of the absolute abundance of resistant bacteria and resistance genes and  studies suggest an increase in relative abundance during treatment for certain resistant bacteria and genes, although there are no clear patterns about which treatment method is most effective at reduction.

Coastal and Estuarine Bacteria Loads for Source Apportionment

Reference: 16/WW/11/14
ISBN: 1 84057 817 3
Published Date: 24/09/2021

The causes of poor bathing water and shellfish water quality represent a significant challenge for the UK water industry. This project has assessed the abundance of faecal indicator organisms (FIOs) in estuarine waters and sediments, with a particular focus on ‘viable but non-culturable’ (VBNC) bacteria, and on viruses. Two study areas were selected for sampling - the Ribble and Conwy estuaries. The results suggest that the VBNC fraction of FIOs in sediments may be significant, especially in the winter. Small quantities of Norovirus were only found at two sampling points in the Ribble, and in the winter only.  Results also indicated that cohesive sediments harbour more bacteria than non-cohesive sediments and the water column. This work has proposed practical recommendations for improving the existing monitoring and modelling framework, which will assist the UK water industry in making more efficient investment planning decisions to improve coastal/estuarine water quality.

UKWIR’s Source Apportionment GIS Model (SAGIS): Version 4.0

Reference: 21/WW/02/13
ISBN: 978-1-84057-912-3
Published Date: 23/02/2021

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.
