Development of suitable techniques for reclaimed water in rural areas
4 June, 2050
Waste water source
The wastewater comes from the wastewater treatment plant of Saint-Jean-de-Cornies which treats domestic wastewater.
The effluents discharged from the wastewater treatment plant will be dispatched to a disinfection unit. The effluent destined to go through UV disinfection and electro-oxidation will be filtered before these disinfection systems. The reclaimed water from the disinfection systems will be stored in small containers before irrigation. Concerning irrigation practices, drip and sprinkler irrigation will be implemented.
This demonstration will be performed on fodder crops and vegetables at research facilities. The RUR’EAUX project will not supply water to farms.
Waste water treatment description
Nutrient removal : none
Pesticide removal : none
Disinfection : RUR’EAUX platform aims at testing sanitation and disinfection technologies and putting them into practice for rural water reuse. Four different modules based on a gravity membrane, an electro-oxidation (EO), an aerated reed bed filter and UV are first being implemented to intend a total purification of the wastewater.
Suspended solids removal : The original plant is a 1-stage vertical reed bed filter, the treated water is discharged into a small creek after treatment.
The capacity of the wastewater treatment plant is 60 m³/day (from which 70 % will be used for the project).
Extent of the agricultural beneficiaries
The experiment will be performed on lysimetric containers and micro-plots (25 m²).
The total cost of the project is 800,000 euros. The cost of reclaiming the water is yet unknown.
Type of agreement
The initiative has an explorational status. The consortium set up a consortium agreement between the project partners.
After treatment the RUR’EAUX platform enables :
(1) to monitor and compare water quality evolutions into different storage conditions.
(2) to test irrigation materials tailored for water reuse.
(3) to monitor, thanks to equipped lysimetric containers and test fields micro-plots, the impacts of water reuse on soils, crops and drainage water, especially on long term effects of salinity.
Cost-efficiency of all tested technologies (treatment systems, storage and irrigation materials) in field conditions will be the key monitored indicator. The main objective of the project being to disseminate and reproduce reclamation and reuse systems that are sustainable and profitable in rural areas.
