The majority of the world’s population lives in delta areas. Freshwater demand is high while resources are limited, which is further being challenged by salinization of sources. Securing freshwater for drinking water, industry and agriculture requires innovative thinking on the management of water resources. The innovative COASTAR concept is a symbiosis of mother nature and smart water technology.
SUBSURFACE WATER TREASURY
COASTAR® is the acronym for COastal Aquifer STorage And Recharge. The presence of both fresh and saline groundwater is very common in coastal zones, and freshwater extraction may therefore result in the salinization of groundwater systems. COASTAR focuses on large-scale freshwater supply using the subsurface. Storing freshwater in the underground accommodates imbalances in the availability and demand of water over time and space. COASTAR builds on recent developments in sensoring technologies, groundwater modelling, well design, spatial integration and management, enabling maximum control over underground water resources.
Actually, COASTAR opens a window of opportunities for practical applications. These include efficient freshwater storage and recovery, mitigation of salinization of aquifers, enabling water reuse, water stewardship and improved stormwater management. With a strong reference base in the Dutch water sector, the COASTAR concept represents strong global potential for application.
