How it Works:

corrugated water tankCorrugated Rainwater Collection Tanks are designed and shipped with an interior liner, corrugated metal sheets and a roof as well as many other custom components and accessories.

When the tank arrives it will be in several different pieces that must be assembled and installed once on site. This design lowers your overall shipping costs and makes the field erect tank easier to maneuver and handle. Corrugated tanks are then built layer by layer
with a liner running along the interior of the tank.

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.
