How Olla Irrigation Works — Water Your Garden With Less Waste

Olla irrigation is a gravity-fed, underground watering system that delivers water directly to a plant’s root zone. By working below the soil surface, Olla irrigation dramatically reduces water waste while promoting healthier, more resilient plants.

What Is Olla Irrigation?

An Olla is a porous ceramic emitter buried under or near a plant’s root system. Once connected to a water source, it slowly releases moisture into the surrounding soil.

Water moves through the ceramic only when the soil is dry. When the soil reaches proper moisture levels, the flow naturally slows or stops. This creates a balanced underground moisture field that plants respond to naturally.

How Olla Irrigation Saves Water

Traditional irrigation systems lose water through evaporation, runoff, and overspray. Olla irrigation eliminates these losses by delivering water directly where plants need it.

Benefits include:

• Uses up to 80% less water

• No surface evaporation

• No runoff or puddling

• No overwatering

Plants take only what they need, when they need it.

Why Underground Watering Is More Efficient

Topsoil dries quickly, especially in hot or arid climates. Surface watering often feeds weeds instead of roots and encourages unwanted insects.

With Olla irrigation:

• Soil surface stays mostly dry

• Weeds receive less water

• Insects are discouraged

• Roots grow deeper and stronger

Simple, Gravity-Fed Design

Olla irrigation systems use gravity, not electricity. Water can be supplied by:

• Manually filled reservoirs

• Hose connections

• Rain barrels or water harvesting tanks

As long as the reservoir remains filled, plants are watered continuously.

Important note: Olla systems operate at low pressure only and should never exceed 3 PSI.

Low Maintenance for Every Gardener

Once installed, Olla irrigation requires minimal effort. This makes it ideal for:

• Gardeners with back, knee, or mobility issues

• Busy households

• Indoor and outdoor growers

• Raised beds, containers, and grow bags

A 4,000-Year-Old Solution for Modern Water Conservation

Olla technology has been used for over 4,000 years across Asia, Africa, and the Americas. As water scarcity increases, this ancient method is proving to be one of the most efficient and sustainable irrigation solutions available today.

Less Water. Healthier Plants. Easier Gardening.

Olla irrigation works with nature, not against it — delivering consistent moisture underground while conserving one of our most valuable resources: water.
