Managed Aquifer Recharge
As water demand increases, recycled water can be used to maintain groundwater levels In recent years, groundwater stored in key aquifers has become rapidly depleted. This is due not only to demand, but also to technological advances — notably the introduction of the rotary drill in the 1880s and the submersible electric water pump in the 1960s — that have increased exploitation of ...

Managed aquifer recharge: rediscovering nature as a leading edge technology
Use of Managed Aquifer Recharge (MAR) has rapidly increased in Australia, USA, and Europe in recent years as an efficient means of recycling stormwater or treated sewage effluent for non-potable and indirect potable reuse in urban and rural areas. Yet aquifers have been relied on knowingly for water storage and unwittingly for water treatment for millennia. Hence if ‘leading edge’ is defined as ...

Fluence Solutions for Aquifer Recharge
Fresh water can be stored underground in aquifers, but many water sources must be treated before that can happen Growing populations worldwide have become increasingly dependent on groundwater, and human activities are now depleting aquifers - the underground formations where groundwater is stored - faster than natural systems can recharge them. This depletion can damage the environment. As ...

What Is Managed Aquifer Recharge?
Water supply resilience in the face of drought and climate change is a key concern for the UK, as it is indeed for the rest of the world. It can be easy to fall into the trap of thinking that the UK won’t face water stress and scarcity issues, thanks to its famously damp climate, but experts have predicted that changes in weather patterns, rising temperatures, greater variability in ...

Can Texas Floodwaters Be Used for Aquifer Recharge?
A study has found stormwater that washes to the Gulf could replenish aquifers — if it can be caught and stored Flooding in Texas has long punctuated the state’s history, even entering into popular culture. But even though Texas may be legendary for getting its share of rain, the volume of Texas stormwater had never actually been quantified before. A new University of Texas study, ...
