Rainwater Tank Sizing - Commercial


This rainwater harvesting hydraulic model uses 55 years of daily-rainfall data from the closest available location to determine the most economical water tank for your particular case. The cistern is the most expensive single component of a rainwater harvesting system and should be considered thoroughly. To obtain a result we use a method of reservoir routing to form a hydrology model of your rainwater harvesting system. Historic daily norms, your daily water usage, the collection surface area, and a few specifics about the system, dictate the most water each system can possibly need to store in order to fulfill your water usage needs while keeping the cistern volume to minimum.
