Manufacturer specified performance targets Designer / Manufacturer specified targets

The Warka Water Tower was designed to be able to harvest 100 L/day. The designer specifies this solution should be community-run and owned, and easily integrated into the community.

Vetted performance Findings of manufacturer evaluations or independent testing centers

Testing performed by University of Rijeka, determined that the Warka Water Tower was able to collect every type of usable precipitation to maximize water collected.

Testing organizations Independent lab, academic research centers, etc.

Testing organizations include the University of Mumbai and the University of Rijeka.

Safety Potential hazards / risks related to operation of this product

No known safety hazards are related to this product.

Complementary technical systems Performance of this product is improved with another technology (eg. Cookstoves and Wind-blocking skirts)

The Warka Tower can have a number of add-ons such as WSolar, Warka Garden, and Warka Sanitation.
