Unpowered Terracotta Irrigation Controller

Unglazed terracotta pots have been used for water-saving irrigation since the first century BC. A remarkable new invention is now using an unglazed terracotta pot as the centrepiece of a state-of-the-art unpowered irrigation controller. An adjustable control dripper is connected to the irrigation system so that it drips water into the pot during the irrigation. A float inside the pot is used to control the opening and closing of the irrigation valve. The irrigation starts automatically after sufficient water has evaporated from the outside surface of the porous terracotta pot. The irrigation stops automatically when the control dripper has replaced the evaporated water. The control dripper can be adjusted so that the water usage is appropriate for the water requirements of your plants. The irrigation frequency responds automatically to the prevailing on-site evaporation and rainfall. The Unpowered Terracotta Irrigation Controller is suitable for automatic sprinkler irrigation or drip irrigation. The valve operates in the pressure range 10 kPa to 800 kPa. The Unpowered Terracotta Irrigation Controlelr is a game-changer for automated irrigation from a rainwater tank without using a pump.
