A bore consists of pipes(casing) extending into the groundthrough which groundwater is drawnfrom an underground layer of water-bearing permeable rock (the aquifer) to the surface. Thecasing supports the walls and preventsrocks and debris collapsing the boreand contamination by surface runoff.
In some small bores thepump is connected directly to the top of the bore casing or to a suction pipeinside the bore.
