We have developed solutions that allow treated wastewater to be used to supplement the natural recharge of underground aquifers.
Except for fossil aquifers, water tables are replenished naturally by rain, rivers and streams. The rate at which water is withdrawn from aquifers, however, is often far higher than their natural rate of replenishment. In several European regions, for example, aquifer levels are dropping by one to three meters a year due to overuse. Rebuilding aquifers artificially using treated surface water, storm water or wastewater can store water so that resources are available immediately when needs spike.
Veolia Water's recharge techniques minimize and even entirely eliminate the land subsidence risk associated with aquifer overuse. They can also be used to prevent saltwater from seeping in and contaminating coastal aquifers. In practice, aquifer recharge is a three-step process.
We already successfully recharge aquifers in a number of countries, including Australia, the United States and Germany. Our reliable plant management and our proficiency in treatment techniques such as clarification and filtration enable us to reuse treated wastewater to recharge aquifers without endangering public health.
