Details

The sewage sludge code of practice is for anyone in England, Wales and Northern Ireland who produces, supplies or uses sewage sludge. Owners or managers of farmland where it is used should also read this guidance.

It helps to make sure that when you produce, supply or use sewage sludge you:

  • follow good agricultural practice
  • maintain the long-term viability of the soil
  • avoid public nuisance and water pollution
  • protect human, animal and plant health
