The UK Department of Trade & Industry (DTI) under the Flow Research Programme (KT13 Auditing Flowmetering Systems), published a series of Flowmeter Auditing Guidelines in March 2002. The guidelines provided a thorough and consistent approach to auditing meters in water supply and distribution. Welcomed by the industry, the guidelines are publicly endorsed by the Regulators. The UK water industry, through the Water Industry Flow Liaison Group (WINDFAL), is keen to adopt and further develop the guidelines. The Regulators indicated that they would look favourably on Utilities who adopt the practices.
The guidelines - which are extremely comprehensive and detailed - have not yet been widely used in typical water industry applications. This project explored the practical implementation of the guidelines to deliver real benefits from the information produced.
Business processes, which realised benefits from the effective implementation of the guidelines, include:
- Water balance calculations (derivation of the uncertainty in water delivered).
- Leakage management (quantifying the uncertainty in water supply and District Meter Area (DMA) meters).
- Asset management (development of meter replacement and repair strategies).
- Regulatory reporting (e.g. verification of reported abstraction data).
