Water from farms will suffer different degrees of contamination from minimal to potentially highly polluting. The level of pollution will determine how they are managed.
Clean water –this can be discharged to ditches and soak-aways
Lightly contaminated water –this will require some form of particle traps, eg biological filters and treatment such as swales/reedbeds
Contaminated water –anything with a polluting potential will need to be contained and managed appropriately, eg slurry
