Slurry storage

Tips, tools and advice on slurry storage to help livestock farmers reduce costs, add value and protect the environment.

This information will help ensure that the slurry store on your farm is practical, safe, and legally compliant. Key points to consider are:

  • How much storage do you require?
  • Have you taken action to reduce the amount of slurry you produce?
  • Do you have the necessary permissions?

Slurry stores need to be big enough to get you through winter. This video, from AHDB, the Environment Agency, Catchment Sensitive Farming and Severn Trent, explains how to calculate how much storage you need.

Location and permissions

Slurry stores can pose a risk to the environment and cause a statutory nuisance to the public. Therefore, it is important to choose the right location for your store and gain the correct legal permissions before it is constructed. You must find out about your legal responsibilities when constructing a new store or altering an existing one.
