Risk Assessment tools and tips
Introduction
This page provides the tools to assist risk assessments of private supplies. For general guidance on the requirement to risk assess see the information notes here.
Conducting a risk assessment
The Inspectorate has developed a number of risk assessment tools to assist local authorities in undertaking risk assessments for private water supplies as required by regulation 6 of The PWS regulations 2016. These tools can also be used for supplies to single domestic dwellings where a risk assessment has been requested.
In response to requests from local authorities for a condensed version of the risk assessment tool for use on simple systems with common types of treatment, there is also an edited version of the tool. This is listed as ‘risk assessment lite’ and may be typically used on supplies that consist of a single source followed by one or two stages of treatment, such as prefiltration and UV disinfection.
Please ensure you use the most up to date version of the risk assessment tool. The version number can be found on the first tab in each tool. All tools should be compatible with Excel 2010 onwards. Please contact the Inspectorate should you experience any compatibility issues.

A training video is available on the online risk assessment tool.
These tools are produced under licence, permitting third parties to use the risk assessment tool by local authority agreement, and without altering, copying or using it for commercial gain. The tools are therefore provided in a protected format and we cannot supply them unprotected.
DWI has also produced an Action Plan look up table listing common mitigation measures.
