When the borehole is completed we install the well head and water pumping equipment.

• We place a thermo-plastic well screen into the bore. This is slotted in the vicinity of the underground aquifer to allow water to pass through to the pump.
• The area around the well screen is then filled with a gravel pack up to approximately 3 metres below the start of the rock formation, to form a water filter.
• A bentonite plug is placed on top of the filter pack.
• Grout, injected into the remaining space to the top of the borehole, forms a seal and stops any cross contamination.
• We construct a sealed chamber, at ground level, to house the well-head assembly and allow easy access and maintenance.
• Finally, we install a stainless steel submersible pump, powered either by electricity or a renewable energy source such as solar or wind power. Attached to the pump is a rising main which brings water to the surface.
• We can also install any distribution pipe-work required, either to an existing system or a water tank.
