Project: Artificial recharge of treated wastewater effluent into groundwater lenses to enable sustainable groundwatermanagement

01/11/12 – 31/10/15

The aim of the proposed project is to perform advanced wastewater treatment on wastewater effluent, followed by the artificial recharge of this treated water into a groundwater lens. This will result in the augmentation of groundwater resources and prevent the further depletion and deterioration of the groundwater. Hence, a long-term sustainable groundwater management might be achieved. The study comprises: 1/ a hydrogeological study determining the aquifers and aquitards of groundwater reservoirs around important effluent discharge sites; 2/ an advanced wastewater treatment, including ultrafiltration and reversed osmosis, at pilot scale in view of producing high quality water out of wastewater; 3/ a direct artificial recharge of the treated water into suitable fresh or moderate brackish water lenses; 4/ a follow up of the groundwater quality in function of future water reuse purposes. The current project idea is based on a similar study performed in Belgium during the 90s which resulted in a full scale application in 2002.
