The premise of ‘Rainwater Harvesting Project at a farm on St.Erasmo Island’ was to reach across disciplines of art and architecture to imagine the future of the Venetian lagoon as a sustainable environment.

A rainwater-harvesting system on a farm on Sant’Erasmo island in the Venice Lagoon (re)introduces rainwater as a valuable resource for the farm. Rainwater collected from greenhouse roofs is used to irrigate the crops inside. Like Venice itself, the farm’s very existence is dependent on water. But because the Lagoon is subsiding, the Venetian government plans to limit the use of water from underground aquifers, a measure that threatens local food production and farmers’ livelihoods. Water, once Venice’s closest ally, has become her enemy. The rainwater-harvesting project seeks to model an alternative paradigm to this adversarial relationship.

The farm considers the project a useful prototype to evaluate the benefit of rainwater harvesting for their particular needs. It will also allow for a comparison between the quality of vegetables irrigated by rainwater.
