The Aquifer Partnership

Protecting our aquifer so that we can all have access to clean, safe water in the future.

The Aquifer Partnership is working together to ensure a sustainable future for our local groundwater.

The city of Brighton and Hove and surrounding towns and villages all obtain their drinking water from groundwater that is stored in a natural aquifer under the South Downs.

However, this groundwater is at risk of pollution as a side effect of farming and modern lifestyles, and from being over-used due to increasing population pressures.

The Aquifer Partnership is delivered by South Downs National Park, Brighton & Hove City Council, Southern Water and the Environment Agency working with stakeholders from across the rural and urban landscape of the Brighton chalk block.

The project started in 2015 and there are many opportunities for residents and businesses to protect our local groundwater.

Project objectives

  1. Working with farmers and landowners to trial new approaches that use nitrate efficiently and stop it getting into soils, surface and ground water.
  2. Working in the urban environment to stop surface water pollution from roads and developments impacting our groundwater.
  3. Supporting innovation and research to develop new ways of reducing ground water pollution in rural and urban environments.

What’s been achieved?

  • Research with farmers into using winter cover crops and regenerative farming techniques to support the soil and reduce nitrate leaching.
  • Developing plans with two schools in Brighton and Hove to install rain gardens in the school grounds to improve biodiversity and reduce surface water flooding.
  • Developing plans with Brighton & Hove City Council to install a large rain garden in the city to remove pollution from a major road and reduce surface water flooding.
