Rainwater Collection Tank Sizes

Determining the right tank size for your location is dependent on several different factors including anticipated rainfall and anticipated water use for your household or business. For most locations, standard rainfall amounts can be found through historical weather data services. You can use the Water Collection Calculator for reference. If you are in a location that deals with frequent periods of low rainfall, it is typically recommended that your rainwater collection tank is able to hold enough water to successfully get you through these periods of time.
