Olive trees irrigated with treated wastewater, a pilot project to combat drought

Olive trees irrigated with treated wastewater: in Puglia, southern Italy, a pilot project thus combats drought and emerging pollutants. The molecule is generated by combining hydrogen peroxide and ultraviolet rays. The results of this experience will be known in two years.

In partnership with the European Commission

00:00In the Adriatic Basin, every drop of water counts.
00:04Here in Puglia, in southern Italy, water shortages have got worse with climate change.
00:10And on top of that, a bacterium has decimated the olive groves.
00:14The EU EcoFlow project brings together Greek and Italian experts.
00:18The idea is to irrigate land by reusing treated wastewater from Gallopoli, which would otherwise go into the sea.
00:25On this test site, there are three rows of bacteria-resistant olive trees and three forms of watering.
00:55At the wastewater treatment plant in Gallopoli, the water for the EcoFlow project is purified even further,
01:01using a patented mini-station that was developed as part of another EU project called ReWater.
01:08So what is the process for further disinfecting the water?
01:30EcoFlow has a budget of over one and a half million euros, 75% of which has been financed by
01:37the EU Cohesion Policy,
01:38and the remaining 25% was funded by Greece and Italy, the two countries participating in the project.
01:48The laboratory of the Politechnic University of Bari provides technical and scientific support to the main partner of the project
01:55for the tests that are carried out for EcoFlow, both with water and with soil,
01:59on the two varieties of olive trees that are watered.
02:23This farm produces over 60 tons of olives each year.
02:27The owner waters part of his crops with water from his well
02:30and a younger olive grove with water that has been treated as usual
02:33and supplied by the Gallopoli concert here.
02:36And he can already see the difference.
02:40We didn't expect that the plants of four years come in production
02:47and so we were happy to have found a more rapid development of the plant,
02:53probably due to the type of water used.
02:56The live shadow.
02:57And then, though, for many years of the harvesters,
03:00And in Augusta Euro Mostly
