EPA’s Water Abstraction Volume Estimator

Registration of a water abstraction is required when then maximum daily abstraction is expected to exceed 25 m3/d and is not required for any abstraction below this amount. This document can be used to estimate abstraction volumes for various sectors where the abstraction volume is not directly monitored.

The estimates in this document have been prepared in consultation with the various sectors who abstract water and following review of relevant studies on abstraction volume

The following sectors are known to have abstractions greater than 25 m3/d:
1. Agriculture (Livestock);
2. Agriculture (Irrigation);
3. Agriculture (Horticulture);
4. Drinking water supply (Public Supplies);
5. Drinking water supply (Group Water Schemes and large private supplies);
6. Aquaculture;
7. Golf course;
8. Hydropower;
9. Industrial (IPC/IED/Waste licensed);
10. Industrial of commercial (unlicensed));
11. Mining and quarrying;
12. Peat extraction;
13. Horse Racing Courses.
