Groundwater Recirculation System (GRS)

St Marys is proposing a proven water-recirculation method and will take additional steps to make certain that it will work at this location. The GRS method has been successfully employed at other limestone quarries in various locations around the world.

Since geological and groundwater conditions can vary widely from site to site, the suitability of this technology must be evaluated on a site-by-site basis. As such, the application of this technology at the Flamborough site also needs to be demonstrated.

St Marys has applied for a Permit to take Water (PTTW) so that we can undertake thorough testing, and prove that our Ground Water Recirculation System (GRS) will work in Flamborough.

St Marys is committed to successfully demonstrating our GRS method here in Flamborough before this system is implemented or added as a component to our final application.

How does GRS work?

The GRS method recirculates water to maintain the water levels. Water is extracted and reintroduced to the groundwater system, which is then drawn towards the pumping wells to be extracted again. At no time will we be removing water permanently from the aquifer/ground.
