Group Against Reservoir Development

GARD: Group Against Reservoir Development

GARD campaigns for a smarter, sustainable water strategy in the South East that ensures resilience against population growth, climate change, and drought.

Using inflated demand projections, Thames Water is pushing for a reservoir without proper scrutiny, ignoring flood risks and design concerns. This flawed scheme risks decades of environmental harm and financial cost.

People matter: together we have a voice

The Reservoir needs planning permission to go ahead. Thames water does not have this permission yet.

Thames Water is preparing to apply for planning permission for the White Horse Reservoir, in November 2026. Because the proposed Reservoir is a major national infrastructure project, it bypasses local planning, and Thames Water must apply to the Planning Inspectorate for a Development Consent Order (DCO).
