The image is a blue sign attached to a green metal wall. The sign reads "Thompson Steam Engine/Pump (1924)". Below the text, there is a description of the steam engine/pump, which consists of two 24 inch (0.6m) centrifugal pumps, direct coupled to the 680 horsepower (510 kW) triple expansion steam engine, delivered 600,000 gallons (2.7 Megalitres) of water per hour from each pump. Originally located at the nearby Loveday Pumping Station, these pumps relifted water supplied by the Humphrey Pumps for irrigation of higher land.
