Reuse of reclaimed water for corn irrigation

4 June, 2050

Reuse of reclaimed water for corn irrigation


Waste water source

Municipal wastewater is used from the Aureilhan wastewater treatment plant.

Distribution System

The distribution system should supply the experimental fields that belong to 2 different farmers. However, many issues have araised with social acceptability and the position of the distribution network. The distribution systems were not installed yet by mid-2020.

Farming system

Arable land with corn, cultivated intensively.

Waste water treatment description

Nutrient removal : Activated sludge
Pesticide removal : none
Disinfection : UV and gravity driven membrane filtration
Suspended solids removal : Primary treatment : Grit removal, screening, de-oilling
Other :


The potential capacity is around 3,700 m³/day.

Extent of the agricultural beneficiaries

10 ha of arable land is irrigated with the reclaimed water.


The total budget of the project is 5 million euros, the cost of the reclaimed water isn’t known yet.

Type of agreement

Seen the explorational status of the project, a consortium agreement was made between the project partners.
