An Overview of Managed Aquifer Recharge Using Effluent

The ever-increasing global population, coupled with the expansion of industrial and agricultural activities, as well as recurrent droughts in recent years, has led to the near-maximal exploitation of freshwater resources. Various methods exist for recharging aquifers, with particular emphasis in recent years on one method that plays a pivotal role in sustainable resource management: Managed Aquifer Recharge (MAR). MAR represents one of several approaches aimed at fostering long-term water resource sustainability by bolstering the natural replenishment of groundwater reserves through the introduction of surplus waters, including additional surface water, stormwater, and treated wastewater. Managed Aquifer Recharge entails a meticulously orchestrated process guided by human intervention. This process involves channeling water towards an identified region, whether it be unsaturated or saturated, with careful consideration of soil permeability characteristics. Subsequently, the water is afforded the opportunity to infiltrate the designated unsaturated or saturated area. One of the most prevalent approaches to recycling various categories of water and wastewater from treatment facilities involves the practice of Managed Recharge of subterranean aquifers. Furthermore, this method serves the purpose of compensating for and replenishing the water extracted from these aquifers. One viable strategy encompasses the utilization of a geo-treatment system, in which partially treated wastewater is intentionally introduced into the aquifers to be available for future consumption subsequently. The technique of soil purification finds applicability in regions like Iran, characterized by scarce water resources and a surplus of available land. The soil demonstrates commendable efficacy in the removal of phosphorus and cadmium. However, a substantial portion of nitrate, total organic carbon, and a fraction of nickel are conveyed to the effluent streams.
