Technological and Economical guide for Freshmaker application
“The Freshmaker is a Subsurface Water Solution (SWS) that has been developed within in the past decade and tested within Subsol. The practical concept enlarges, protects and sustainably utilizes shallow fresh groundwater lenses in brackish to saline aquifers by the interplay between overlying horizontal directional drilled wells (HDDWs).
A pilot was carried out in Ovezande (The Netherlands) since 2013. This pilot has proven that the Freshmaker is a suitable SWS to reduce problems related to water quality or availability for water users with a seasonal variability of freshwater demand. Improvement of the Freshmaker in Ovezande, and further improvement of the technique in Groede (The Netherlands), have both contributed to the development of a reliable system for subsurface storage of freshwater in coastal areas with a brackish-saline subsurface.
This Technological and Economical guide serves as a starting point for end users of freshwater (with a strong interest in a self-reliant freshwater supply), engineering companies and installers, technology providers, consultants, and water managers interested in the development of a Freshmaker at other coastal sites with temporary water shortages and a brackish-saline subsurface. Through a feasibility study of the water balance and the geohydrology at a specific site, the supporting Freshmaker Tool proposes a design and an operational scheme, and estimates the costs involved for installation and implementation.”
