Abstraction Licensing

Assist in water resource abstraction licensing

Schlumberger Water Services (SWS) has undertaken projects covering all aspects of water resource abstraction licensing, from assessment of the impact of individual abstractions to development of suitable methodologies for the regulation of abstraction and allocation of water resources. It is always important to understand the local legal context for abstraction licensing, and our international experience enables us to compare best practices from many different countries.

Project Examples:

Impacts of Dewatering
Location
- UK
Client - Environment Agency
Description - In England and Wales, new legislation came into force in 2003 that removed the exemption from abstraction licensing previously enjoyed by dewatering operations in mines and quarries. The Environment Agency commissioned SWS to develop a flexible and robust methodology for the assessment of the hydrogeological and environmental effects of dewatering abstractions. This methodology will become a key component of national guidance issued by the Environment Agency, applicable to all active dewatering operations.


Burton Aquifer Resources 
Location
- UK
Client - Environment Agency
Description - The UK Environment Agency commissioned SWS to determine the sources of water and sustainable yield of the deep confined Triassic sandstone aquifer in the Burton district, an important source of water for the local brewing industry. A conceptual model of the Burton Groundwater Management Unit was developed through detailed analysis of geological, hydrological, and hydrogeological data. A 3D time-variant, finite-difference (Visual MODFLOW) numerical model of the area was constructed and used to further test the conceptual model. Conclusions were reached on the probable sources of water for the deep confined aquifer, the present impact of abstraction on water resources, and the future implications of further licensing of abstraction from the aquifer in terms of groundwater levels and quality.


License Renewal 
Location - UK
Client - South Staffordshire Water
Description - South Staffordshire Water retained SWS to prepare an environmental report, including a hydrogeological impact assessment, to back up an application for renewal of a groundwater abstraction license for a public water supply borehole. The abstraction is close to a sensitive Site of Special Scientific Interest, and the project specifically addressed the potential impact of the abstraction on the local water environment.
