Updating the groundwater protection code for sheep dip - have your say

Overview

Natural Resource Wales is working with Welsh Government to review and update the Groundwater protection code: sheep dip.

Sheep dip is a hazardous substance and following the guidance reduces the risk of groundwater pollution when sheep dip is used, stored and disposed of which helps support a healthier natural environment.

It was last revised in 2017 and we are now consulting on a proposed update to ensure it reflects current policy, industry practice and environmental requirements.

The aim of this update is to:

• Reflect recent changes in policy for the disposal of waste sheep dip.
• Ensure the guidance reflects current best practice and does not harm the environment.
• Make the document easier to follow and use.

The main changes we are proposing are:

• Removing references to new environmental permits for disposing of waste sheep dip to land, as these permits are no longer issued in Wales. Those who still hold a permit can continue to use them for the time being.
• Revising the areas on the farm which are not suitable for dipping sheep.
• Updating the advice from sheep dip manufacturers on how long to wait when rain is forecast to dip.
• Advising against repairing damaged or leaking dip baths and recommending replacement with a new dip bath or the use of a mobile dipping unit.
• Removing references to the enzyme treatment of waste sheep dip that was possible under waste exemption T27 as this product never became available for farmers to use and the exemption is no longer valid.

Here is the proposed groundwater protection code for sheep dip

We have launched a 12-week consultation which will take place between 6 August and 29 October 2026 and we want to hear from you.

Why your views matter

This is an opportunity for farmers, land managers and others with an interest in sheep dipping to help shape the final guidance. Have your say and let us know if you support the proposed changes.

We want you to share any suggested changes and tell us where the guidance is difficult to understand or if there are parts of it which are not practical to follow.
