In keeping with J&S Drillings reputation for quality deep Production Bores we recently completed a 170m deep Production Bore to supply the tunnel boring machines drilling water for the Perth Transit Authorities Forrestfield Airport Link Tunnel.
Contracted to the Saligni Impreglio NRW JV we completed the drilling and installation on time and within budget. Down Hole geophysical logging and Hydrogeological reporting determined that the design and flow could be improved from the original scope of work by drilling deeper and altering the installation design.
These design amendments ensured higher rates of flows up to 32 litres per second would be available if required.
Test Pumping confirmed the constant rate flow of 20 litres per second was readily achievable.
