Coastal Freshwater Protection

 Discover how breakthrough innovations enable coastal communities to protect freshwater reserves

How to protect against saltwater intrusion?

Coastal communities experience the disruptive impact of rising sea levels on depleting freshwater reserves. Urgent action is needed to stop saltwater intrusion.  

As a basic line of defence, the unique patented Underground Dam © Technology seals freshwater aquifers against incoming salt water. Based on precise iFLUX Sensing © measurements and predictions of saltwater flux, impermeable shields of environmentally friendly glass are installed by precise injection at the right depth and length. As a result, freshwater reserves are protected vertically and/or horizontally against saltwater intrusion for decades. 

How to manage and recharge coastal groundwater reserves?

Coastal groundwater reserves are under pressure, caused by over- extraction, long periods of drought and contamination by saltwater. 

As a reliable single base for coastal water management we offer the Roak© Data Analytics Platform and a suite of proven hardware devices to measure water quality and quantity.  This includes iFLUX Sensing© to measure and predict underground movement of clean and contaminated aquifers. 

The BlueBloqs© Rainwater Harvesting is the proven technology for recharging aquifers and feeding freshwater reserves with clean water at attractive economic conditions. The BlueBloqs© below ground seasonal water storage can be a source for agriculture and non-potable clean water for industries and coastal communities. 

Where to find coastal water reference cases?

The coastal freshwater protection technologies have been applied at multiple locations.
