Underground or sub surface drip irrigation systems for lawns are also available. These systems generally need to be installed before the lawn is laid.
Controllers for drip irrigation systems
vary greatly, from a simple tap to turn the system on and off, to electronic controllers that allow preprogrammed irrigation times and zoned watering. Rain sensing controllers that turn the system off are also available.
Soil moisture sensors can also be fitted to drip systems, these can be adjusted to turn off or on the irrigation depending on detected soil moisture in the garden.
Filters for drip irrigation systems
As the drippers usually have very small outlets or openings it is common practice to fit filters to drip systems to prevent clogging and blockages.
