Experimenal site of Murviel-lès-Montpellier
4 June, 2050
Waste water source
The reclaimed water originates from the domestic wastewater from Murviel-lès-Montpellier. The wastewater treatment plant is operated by SUEZ.
A lagoon is used as storage. There is also a 4 m³ container for temporary storage of small volumes. The water is distributed with pressurized pipes having a total length of just less than 1 km.
The experimental site contains various cropping systems. There are vegetables eaten raw such as salad or leek. They are grown on a raised bed under glass, as well as fruit trees (olive trees) and vineyards.
Waste water treatment description
Nutrient removal : none
Pesticide removal : none
Disinfection : Micro-filtration
Suspended solids removal : Lagoon based system
The daily amount of cleaned water is around 200 m³.
Extent of the agricultural beneficiaries
The experiment concerns two experimental sites: one plot where water is applied under controlled conditions (soil tanks) and an agriculture field under real conditions of 0.5 ha.
No information available.
Type of agreement
Seen the explorational status of the initiative, a consortium agreement was made between the project partners.
Several experiences have been carried out regarding
(1) Agronomic performance of wastewater irrigation on lettuce and leek as well as crops and soil contamination by the reclaimed water
(2) Biofouling formation in drip irrigation system using reclaimed water
