Zusammenfassung:	A borehole pumping installation comprises a borehole and a pump located down the borehole so that it is at least partially submerged in water in the borehole. The pump has a reciprocable piston or plunger such that on reciprocation of the piston or plunger, water is urged out of a pump outlet. An elongate member is connected to the piston or plunger and extends up the borehole so that, on reciprocation of the elongate member, the plunger or piston moves in reciprocating fashion. A flexible water conduit or casing leads from the pump outlet along the borehole to the surface. Reciprocating drive means is operatively connected to the elongate member.
