Low Flow/ Abstraction Studies
HLS have undertaken Hydrometric monitoring for numerous studies to assess the impact of abstractions on the natural environment. These studies have been undertaken over the past three Asset Management Plan (AMP) spending periods, since 2000, and before. Many of these are classified under the Environment Agency Restoring Sustainable Abstraction (RSA) and National Environment Programme (NEP) schemes, with Water Framework Directive (WFD) and Habitats Directive compliance being important criteria.
Working in collaboration with partners, we can provide the whole package of hydrometric monitoring, aquatic ecology surveys and groundwater monitoring, and the associated analysis, to provide a one-stop-shop for such projects. Alternatively we can provide just the specialist hydrometric inputs to work being undertaken by framework consultants.
The services that we provide include:
- Spot Flow Gauging Programmes
- Establishment of temporary gauging stations
- Groundwater monitoring
- Water Quality monitoring
- Rating development and review
- Desk studies to review existing data and recommend monitoring requirements
- Monitoring in accordance with Hydro-Ecological Flow Threshold (HEFT) methodology
- Hydrological analysis to determine the impact of abstractions
We have undertaken this work for: South-West Water, Wessex Water, Thames Water, Southern Water, South-East Water, Portsmouth Water, Affinity Water, Severn Trent Water, South Staffordshire Water, Anglian Water, Dwr Cymru Welsh Water and United Utilities.
