Terracotta Valve

This remarkable new invention is now using an unglazed terracotta pot as the centrepiece of a state-of-the-art unpowered irrigation valve. The Terracotta Valve is suitable for automatic sprinkler irrigation or drip irrigation. The Terracotta Valve does not require an irrigation controller. Each valve is self-controlled whereby variations in the irrigation frequency are automatically controlled by the on-site prevailing weather conditions.

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 irrigation controller. The irrigation starts automatically after sufficient water has evaporated from the outside of the porous terracotta pot. The irrigation stops automatically when the control dripper has replaced the evaporated water.

Bottomless Rainwater Tank Attachment

Many gardeners would like to use their rainwater tank to irrigate their garden. However a problem arises when the rainwater tank runs out of water. The ideal solution is to install the Bottomless Rainwater Tank Attachment so that your rainwater tank never runs out of water. The Bottomless Rainwater Tank Attachment is completely external to the tank and so it’s easy for anyone to install.

Unpowered Measured Irrigation Controller

You can leave your garden unattended for weeks on end. The Unpowered MI Controller is incredibly simple and so there are fewer things to go wrong. This video is for smallholders using drip irrigation (either pressurised or gravity feed) on a small plot of land. It is a smart irrigation controller because the irrigation scheduling is controlled by the prevailing weather conditions.You can adjust both the water usage and the irrigation frequency.

Innovation and gravity feed irrigation

This video features a large garden in Adelaide using gravity feed irrigation from a header tank. A single zone can be used because the pressure at the tank outlet is the same regardless of the number of drippers. There are about 1000 non pressure compensating drippers and the pressure at each the dripper is about 50 cm. For conventional pressurised irrigation a pump is needed and the single zone would need to be replaced by many zones. The water usage is directly proportional to the prevailing net evaporation rate.

DIY smart irrigation

This video provides step by step instructions so that smallholders can use smart irrigation scheduling. All that is needed is a steel pipe and a storage container. Use for high or low pressure for any irrigation zone, big or small. The irrigation scheduling takes account of

the evapotranspiration of your plants, the soil type, and the depth of the root zone.

DIY Smart Irrigation Controller

The Smart Irrigation Controller is Do-It-Yourself and so you can minimise the cost by using locally sourced components.​

  • No electricity is needed (no batteries, no solar panels, and no electronics)

  • You can adjust the water usage by adjusting the control dripper

  • You can adjust the irrigation frequency by changing the evaporator

Irrigation innovation uses the weather to control litres per week per dripper

This video is for anyone who uses drip irrigation (pressurised or gravity feed) and would like to reduce their water consumption. All that is needed is a bucket. After you have upgraded to measured irrigation, the number of litres per week emitted by each dripper is directly proportional to the nett evaporation rate.

Upgrade gravity feed drip irrigation to measured irrigation, using evaporation data 

By upgrading to measured irrigation, you will save more water by controlling the application rate for each plant during the hottest dry month of the year. Save more water by allowing the prevailing weather conditions to control the variations in the application rate throughout the year. The cost of the upgrade is simply the cost of a bucket .

Think twice before you buy a pump for your rainwater tank

With measured irrigation you have much more control over the amount of water used for each plant. You don't need a controller because measured irrigation is controlled by the prevailing weather conditions. Measured irrigation is incredibly simple and inexpensive so think twice before you buy a pump for your rainwater tank.
