2L is a modular rainwater storage that utilizes empty beverage bottles.


Rainwater is one of the most valuable resources around us. However, it is often overlooked. Most of rainwater runs straight to the sewerage and goes to waste.

Two-liter bottle is a common container for soft drink, but 80% of the plastic bottles that are bought in the U.S. go unrecycled and end up in landfills. To collect and storage more rainwater, 2L utilizes empty beverage bottles.

Empty bottles are connected to the 2L panel's holes and each panel can hold about 120 liters (32 gallons) with 49 of two-liter bottles. Users can install the modular panels side by side and link them with the hose at the bottom, so the panels will be filled simultaneously. The modular panels can be added continuously depends upon how large system the users want.
