What are abstractions?

Abstraction licences can be single site, simple purpose abstractions with no seasonal variation in abstraction limit. Others can contain complex authorisations regarding multiple abstraction locations, different purposes, different seasonal periods and imposed licence conditions. To represent this clearly, Qube divides a licence feature into three levels: the overall licence details, site details (one or more sets of which belong to the overall licence) and purpose level (one or more sets of which belong to a site).

Site details

You can save the following details for a surface water abstraction site.

All site purpose seasons and monthly flows are aggregated to yield a monthly abstraction profile for each site. This is used in the estimation procedures.

The site purpose annual and daily quantities are aggregated to yield the site and subsequent licence annual and daily quantities. The site uptake factor is calculated as the sum of the site purpose monthly profiles divided by the sum of the site purpose annual quantities.

Each abstraction site requires at least one site purpose.

Use the button to view and edit the site purpose.

Site purposes

The influence of an abstraction is specified as an actual monthly profile for each purpose at a site. A radio button records whether the actual monthly profile is derived using returns data from the abstraction licencee.

The season start and end represent the authorised period of abstraction within the year.

The actual monthly profile is used in the estimation procedures, with the percentage return factor subsequently applied. A percentage return factor is required for each purpose if some of the abstracted water is returned and if this amount is not covered by a separate discharge consent (e.g. cooling water return). If no water is returned, a 0% return should be used.

Licence details

The licence details are summarised in the header. Use the button to edit the licence.
