Severn Trent Water Framework for AMP6

Case Study

STW_4col_keyline-400x400ESI has been awarded a place on Severn Trent Water Limited’s AMP6 Water Resource Planning Framework. Running for a minimum of three years, with an option to extend for a further two, ESI is leading an Alliance of expert teams to manage water resource management, hydrology and hydrogeology projects.

“We are delighted to continue our working relationship with ESI into AMP6. We look forward to meeting our statutory requirements and implementing further enhancements to our water resource management plan to the benefit of our customers.”
Adrean Chavira, Lead Category Specialist, Severn Trent

 

Background

 

The AMP6 award follows a decade of work with STWL over the AMP3-AMP5 cycles. Our investigative work in these previous cycles explored abstractions potentially contributing to the failure of water bodies to meet Good status under the Water Framework Directive (WFD). Together with consortium partners APEM and Hydrologic Services Limited robust flow targets for STWL’s affected streams were developed.

 

Our Approach

 

The AMP6 framework award follows over 15 years of environmental investigations by ESI with STWL over the AMP3- AMP5 cycles. Our investigative work in these previous cycles explored abstractions potentially contributing to the failure of water bodies to meet Good status under the Water Framework Directive (WFD).

 

Severn Trent Water Framework for AMP6The leading technical skills available within the Alliance allowed our team to develop robust flow targets used to determine how much additional flow would be needed to support streams reaching good status. The work clearly showed that abstraction was usually low down in the hierarchy of pressures and that land use and stream morphology issues needed to be addressed before the benefits of additional flow would become apparent.

 

The Project

 

Work to assist STWL deliver on its WRMP commitments through the AMP6 Framework includes:

 

Hydrogeology

    • Borehole design and optimisation
    • Groundwater modelling
    • Test pumping, water features monitoring, environmental monitoring and impact assessments
    • WFD groundwater impact assessments
    • Abstraction licence support
    • Groundwater quality catchment modelling and risk assessments

 

Hydrology

    • Flow gauging
    • Aquator modelling and coding
    • Rainfall / runoff modelling
    • Abstraction licence support

 

Environment and Hydro-ecology

    • Low flow alleviation studies and impact assessments
    • WFD surface water / Heavily Modified Water Body impact assessments
    • Ecological sampling, surveying and impact assessments to support drought permit sites

 

Water Resource Management Plans

    • Taking our statutory WRMP through a Strategic Environmental Appraisal and / or Habitats Regulations Assessment

 

The Outcome

 

Severn Trent Water Framework for AMP6STWL places great emphasis on the role of the supply chain to deliver their business needs. Through this proactive and collaborative approach engagement with the environmental challenges STWL is facing in their current business cycle can be achieved.

 

By providing real cost-effective solutions, and providing the right service for the process, their customers will see real long term benefits.
