ABSTRACT:
A percolation test apparatus comprises a water tank (12), a pipe (36) for directing water from the tank into a hole (20) in the ground, an on-off valve (32) for controlling the flow of water in the conduit, and a water level sensor (30) for detecting the level of water in the hole. To perform a test a control unit (14) automatically turns the valve on and off at times determined by the level of water detected by the sensor. To avoid collapse of the hole, and to ensure the correct size of hole for the test, a cage (16) is lowered into the hole. A rain-proof cover (18) prevents rain from falling onto the cage or the ground surrounding the cage.
