3) How much feed bunker runoff must be caught and stored? 

• Leachate from a typical bunker for 200 head would be about 2500 ft3 per year.

• The volume of the first flush to be stored would be about 15,000 ft3 per year if only the 0.2 inches of the first flush is caught.

• The volume of runoff would be about 17,500 ft3 from the bunker to be stored.

• This would increase the annual storage volume in your manure storage facility by about 15%.
