Typical Capacity Guide for Cows
Typical capacity for cow slurry 
= no. of cows x 12 gallons (54 litres) x no. of days storage required

Typical capacity for washing etc 
= no. of cows x 4 gallons (18 litres) x no. of days storage required
= gallons of slurry storage required

Typical Capacity Guide for Pigs
Typical capacity for pig slurry 
= no. of pigs x 1.5 - 2.0 gallons (7-10 litres) x no. of days storage required
= gallons of slurry storage required

N.B. Allowances should be made for the following when calculating sizes for slurry tanks:
1. Dirty water from open yards (500 gallons per 1000 sq.ft area for every inch of water)
2. Rainfall on the tank itself
3. Freeboard - regulations state that 300mm (1ft) must be left between the slurry and the top of the tank
