Water Resource Reliability Data

The Resource Reliability data indicates the percentage of time additional consumptive abstraction may be available and what this means for abstraction licensing. The Resource Reliability data is based on a nationally consistent method. Results have been overridden to reflect local assessments in our Abstraction Licensing Strategies (ALS) published on our website. ALS outline the implications for abstraction licensing of resource reliability.

The data is displayed in the following categories showing Percentage of the time additional consumptive resource may be available

- Consumptive abstraction available less than 30% of the time.

- Consumptive abstraction available at least 30% of the time.

- Consumptive abstraction available at least 50% of the time.

- Consumptive abstraction available at least 70% of the time.

- Consumptive abstraction available at least 95% of the time.

- Not assessed.

This data is not raw, factual or measured. It comprises of estimated or modelled results showing expected outcomes based on the data available to us.
