-FINALIST of Waterless World Competition


Agriculture accounts for 70% of global water withdrawal and is surprisingly both the cause and victim of water scarcity. As water crisis threatens, Hydro-Pass shall come into place to turn over a new leaf.

Agriculture and the rural are inseparable, but mindsets will soon be changed. Inspired by Roman aqueducts, flyovers that connect urban cities to rural areas could act as modern aqueducts to efficiently utilize and reallocate rainwater.

Rainwater used to drain to central treatment plants before being redistributed. Instead, Hydro-Pass adopts in-situ filtration then distributes fresh water to places in need. Part of the water will be used in the in-built aquaponic system for urban farming, bringing agriculture into urban cities. Robotic systems perform synchronized planting and harvesting that is highly time and cost efficient. Mosses carefully planted cleanses the air for crops to grow healthily. Vertical wind turbines power the streetlights and the aquaponic system, which is not only sustainable but reduces both carbon and water footprint.

As aquifers dry out and farmlands droughting, agriculture must adapt and change, shifting towards urban cities. Hydro-Pass – A living infrastructure, creates mini – ecosystems, allocates water more efficiently, and in hope revives droughted lands for a chance of future.
