Significance of Antibiotic Resistant Bacteria and Antibiotic Resistant Genes in Drinking Water (19/DW/02/92)

Significance of antibiotic resistant bacteria and antibiotic resistant genes in drinking water

There is increasing awareness about the presence of antibiotic resistant bacteria (ARB) and antibiotic resistant genes (ARG) in the environment and the risks posed to drinking water. Some studies have demonstrated that sources of drinking water are vulnerable to contamination by ARB and ARG. Water treatment has been found to form an effective barrier for the elimination of ARB, but ARG were eliminated less efficiently. Evidence also exists for the occurrence of both ARB and ARG in distribution systems. However, most of the information comes from studies outside the UK where patterns of antibiotic usage may not be the same as in the UK. On the basis of the information available, there is no evidence to indicate that consumption of drinking water would represent a significant route for the transmission of ARB or ARG.

Workbook for Estimating Operational GHG Emissions – Version 13 (19/CL/01/27)

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 since 2004 and is updated annually to reflect the needs of the industry, including changes in carbon accounting practices. Updated emission factors to align with the latest UK and international data.

The key updates from version 12 to 13 of the CAW are:

Updates of the emission factors to reflect 2018 values

Addition of Hydrogenated Vegetable Oil as a new fuel

Using Smart Meters to Deliver Savings for Consumers (19/CU/02/16)

Improving water efficiency is increasingly seen as an essential policy objective in the UK and Ireland, and governments and water companies are looking at a range of measures to deliver this. Water metering is commonly used as a tool to support efficiency programmes, and smart meters can provide information to customers which could potentially help further in encouraging water saving behaviours. This report examines the commercial and technical case for smart water metering, and the potential for joint energy / water approaches to support this and efficiency programmes more generally. It considers international and UK experience in relation to both energy / water efficiency and smart metering initiatives.

Modelling solid transport and deposition in urban sewerage systems (19/SW/01/19)

The overall aim was to model solid transport and deposition of sediment in urban sewerage systems as a means to investigate the possible impact of water conservation measures taken in the home on the self cleansing ability of a sewerage network.

UKWIR’s Source Apportionment GIS Model (SAGIS): Version 3.0 (19/WW/02/10)

The SAGIS modelling system has become an integral part of the United Kingdom’s surface water quality planning process. SAGIS (in combination with SIMCAT) facilitates the development of plans to achieve compliance with Water Framework Directive objectives.  The primary benefit of SAGIS is that it ensures the Water Industry is not targeting capital and carbon intensive treatment solutions to address pollution arising from other sectors, so ensuring that investment provides value for money for water customers.  Furthermore, SAGIS promotes a constructive working relationship between Water Companies and Regulators through encouraging the sharing of models and data, thereby eliminating unnecessary duplication of effort. This project has made SAGIS compatible with the latest versions of SIMCAT and MPER, a new metal bioavailability discharge permitting tool. Together with new model calibration methodologies and documentation, these developments are the most significant since the original SAGIS development. Project benefits include increased functionality and future-proofing of SAGIS.
