Recycling water for crop irrigation

Veolia is applying its expertise and experience in water treatment technologies to extend the treated wastewater reuse model to agricultural applications.

Treating and reusing wastewater to meet agricultural needs

Tomato growing is an exercise in patience and precision. Water plays a decisive role: cultivation revolves around monitoring the water needs of both plants and soil, and meeting them with quality irrigation water containing the right nutrients. But water’s vital contribution may come under threat, often due to the depletion or pollution of water resources, along with drought conditions.

In line with changing regulations, Veolia is developing water recycling and treated wastewater reuse solutions for the world of agriculture. The Group’s water treatment solutions – for refining, disinfecting and decontamination – have already been used in several wastewater reuse projects and trials.
They can be linked with innovative and intelligent systems to precisely determine crop irrigation needs, offering businesses in water stress areas a reliable supply of high-quality water, and helping preserve water resources worldwide.



  • As part of the SmartFertiReuse project, Veolia and its partners are developing a complete, innovative “fertigation” solution, designed to support the world of agriculture and local authorities with treated wastewater recovery and optimized fertilizer management.
  • In FRANCE, Veolia is trialing the use of treated wastewater for the micro-irrigation of vines in Gruissan as part of the Irri-Alt’Eau collaborative project.
Taking the opportunities offered by new information technologies and intelligent systems, Veolia is implementing smart monitoring solutions to measure, manage and improve energy efficiency in buildings.
Veolia is applying its cutting-edge expertise in the water business to the detection and treatment of all forms of water pollution, including micropollutants like endocrine disruptors and drug residues.
The technologies and solutions that Veolia has developed to transform waste into energy provide sustainable, competitive and effective responses to the energy transition challenges facing local authorities and manufacturers.
Using innovative refining, disinfecting and decontamination solutions, Veolia recovers and gives a second life to wastewater, which can then be reused in various ways, from meeting industrial needs to providing people with drinking water.
