Today all agricultural industry is paying for water delivered by mains to their farms. Mostly metered this gives a clear indication of the quantities of water used.
Each farm is individual but the general requirements are all the same. Storage tank(s), grit and leaf filter and if required a pump. Dairy, beef, tillage, horticulture all require water but in different quantities for different applications.
This water can be used to feed animals, vehicle washing, shed washdown and crop watering. Using rainwater as an alternative you are reducing your required potable water from the local authority which reduces your annual overheads.
