WINEP Case Study: South East Water

Advanced WINEP Woodgarston & Eastbourne

The scheme will implement measures to reduce nitrate pollution in a chalk groundwater aquifer caused by farming land management. This includes running trials and giving advice to help farms become more self-sustaining and reduce the level of water treatment needed.

The scheme has already looked at innovative solutions to managing nitrate leaching using novel industry techniques alongside trials developed by local land managers. It utilises soil science alongside technological and nature-based solutions, to implement measures which improve nitrate use efficiency, protecting water. Results so far have included cover crop trials showing a 58.9% average reduction in nitrate leaching when comparing cover crops to control bare stubble plots. When scaled up across the 1250.01 hectares of cover crops funded through our grants scheme, we estimate to have captured 43.7 tonnes of nitrate which could otherwise be lost to groundwater.

In 2025-2030 South East Water will be continuing the work to further build innovation in the field of nitrate use efficacy through a series of farmer led agricultural trials in Hampshire and want to establish more techniques which support viable agricultural businesses with a reduced impact on water. The aim is to develop a list of evidence-based solutions which can inform farmers how to implement sustainable and business viable options, which improve nitrate use efficiency and protect chalk groundwater.
