Why Use Drip Irrigation?

  • Eliminate wind drift, run-off, misting, evaporation and staining.
  • Keep the soil wet and the mulch dry - reducing weed growth.
  • Site specific - irrigate narrow, tricky shapes that sprinklers just cannot achieve efficiently.
  • Eliminates fungal problems caused by spraying water onto leaves.
  • Unlike conventional systems, drip maintains uniform watering at ground level as plants grow where foliage would normally obstruct the throw of sprinklers.
  • Works perfectly even in areas with low pressure and flow.
  • Stimulates vigorous root growth resulting in rapid plant growth.
  • Ability to apply soluble nutrients via the drip system - fertigation.
  • Ability to use water with higher salt contents as there is no contact with plant leaves.
  • Ability to use Grey water and treated effluent.

FAQ'S

What is drip irrigation?

Drip irrigation is the process of delivering precise amounts of water and nutrients directly to the plant's root zone, drop by drop, offering growers exact irrigation control and efficient use of limited water resources.
Netafim™ PC (pressure compensated) drippers and dripperlines feature continuously self-cleaning, pressure-compensating drippers. They can be placed either as subsurface or on-surface systems, precisely where irrigation is needed.

Why should I use drip irrigation?

Slow, steady flow of water to plants and soil
Shrubs and plants will thrive. Applying water and nutrients directly to the plant's roots is the best way to ensure plant health and vitality.
Easy to install - flexible and adaptable
Dripperline installs easily in tight, awkwardly shaped areas that are hard to reach with conventional spray systems. Netafim's Techline™CV , UniTechline™AS and TechNet™ dripperlines' flexible tubing adapts to the shape of any planting area.
Solves spray irrigation

problems No damaging spray on buildings, windows, fencing, or pedestrians in high traffic areas. Prevents unsightly brown spots on roses and other flowers, since spray never touches the plants. Foliage are kept dry, reducing fungal diseases. 
Improved plant growth

Produces plants that are fuller and healthier. Water and nutrients delivered directly to the root zone promotes healthy plant growth and reduces plant stress. Soil aeration is improved since soil particles are not washed down, decreasing soil compaction and improving root growth.
Reduced maintenance & labor
No moving sprinkler parts that require repair. Installs with far less labor than sprinklers.
Unobtrusive & aesthetic
Brown colored and hidden adjacent to the plant so it does not interfere with landscaping or scenery.
Saves water

Netafim™ dripperline is far more water-conserving than sprinklers. Eliminates water loss caused by evaporation, mist, surface runoff or wind interference.
Cost-effective
Netafim™ dripperline is far more cost-effective than sprinklers as it saves both time and money. Requires less labor to install and maintain, as well as lower overall material cost.
Security
No exposed sprinkler heads, pipes or surface dripperlines to trip on or tamper with.
Reliability and performance
You can count on us. Netafim™ has been the world's leader in drip technology since 1965.

Where should I use drip irrigation?

You'll be delighted with the fuller blooms and greater beauty of your annuals and perennials when watered with Netafim™ dripperlines.
Mature plants and shrubs grow fuller and healthier with dripperlines versus sprinkler watering.

How about those tight or awkwardly shaped areas that are difficult to reach with conventional spray systems?

Netafim™ dripperlines solve the problem and prevent the spraying of walls, window and fences. Consistent watering with Netafim™ dripperlines helps establish and protect new shrub beds and planting areas.

Can I save money by using drip irrigation vs. traditional spray sprinklers?

It is usually more cost effective to install Netafim™ Techline™ CV, UniTchline™AS or TechNet™ systems when dealing with long, narrow strips, awkwardly shaped areas, or tree, shrub and bedding plant areas, both from a materials cost and labor standpoint.
Plus, Techline™CV, UniTchline™ AS or TechNet™ help minimize liability and vandalism and reduce your customers' spending on continued maintenance and water usage.
A simple shrub bed installation is quick and easy, either buried 4" below the surface or beneath mulch UniTechline™ AS.

Where can I find out how to design, bid and install dripperline subsurface or on-surface systems?

Netafim™ irrigation offers a comprehensive series of documents to help you design and install a Techline™CV, UniTechline™AS or TechNet™ system.
Design and installation training is also available through Netafim™ distributors.

What definitions should I be familiar with?

Capillary action:
The radial (outward and upward) movement of water through the soil that fills the spaces between particles with capillary moisture.
Capillary moisture:

Water retained in pore spaces by the surface tension between water and soil particles. This is the primary source of water for plants and is also referred to as "available moisture".
Gravitational water:

Free water in the soil which moves downward due to gravity. After soil has been saturated, the gravitational water percolates downwards, leaving the soil at field capacity.
Field capacity:

As much water as the soil can hold against the influence of gravity. If soil is saturated by rainfall or irrigation and then allowed to drain freely for 24 hours, the soil is usually at field capacity.
Infiltration range:
The rate at which water enters the soil. This rate varies greatly, and may impose a limitation upon the design of an irrigation system since water application rates may result in runoff and erosion.

What about different soil types? What about clay?

Subsurface irrigation works better than traditional sprinkler systems in heavy clay or sand conditions. Even heavy clay and sandy soils are a mixture of sand, silt and clay. Loam, which contains equal proportions of sand, silt and clay, is ideal.
However, plants can thrive in a very broad spectrum of soil textures when subsurface watering is applied at the proper rate and with appropriate spacing.
Different soils create typical wetting pattern shades as seen at right. Note the dramatic overlap ensuring total coverage throughout varying root zone depths.Drip irrigation works great in clay soils.
What most people regard as heavy clay and sandy soils are actually mixtures of sand, silt and clay which will allow for adequate water movement and retention between soil particles.

Do plants have to be watered from "overhead" to wash off dirt and dust?

A report issued by the independent test lab C.I.T. (Center for Irrigation Technology) states that, "…although the [subsurface] research plots are surrounded by fallow fields, dirty leaves have not been noted."

Does water only move downward, pulled by gravity?

When applied slowly to the soil at a single point, water moves through the soil in two ways:

  • Downward, pulled by gravity.
  • Outward and upward, pulled by capillary action.

How can I be sure the system is working?

There are several ways to verify that your system is working:

  • Feel for moisture just below the surface of the soil, directly above a dripper.
  • Run micro tubing to the surface at the end of a zone and use it as a point source dripper.
  • Install a flag indicator at the end of the zone.
  • Monitor flow at the water meter.
  • Because water travels both upward and outward from the dripper, the soil will usually be damp at, or close to, the surface.

When I install a UniTechline™ AS under turf, will I get green and brown stripes?

A proper Techline™ CV, UniTechline™ AS or TechNet™ turf installation with the right watering schedule will produce more consistent watering and excellent turf quality with less chance of disease and water stress.Is "root intrusion" a problem?
Root intrusion is a problem that can be prevented using three different practices, listed at right. Following any of them will help. Using all of them will assure a lifetime of protection.

  • Use Netafim™ UniTechline™AS since it is the only subsurface irrigation product designed with a physical root barrier proven most resistant to root intrusion in tests conducted around the world.
  • Apply a little water every day. If you run your Techline™CV , UniTechline™AS or TechNet™ systems for five minutes a day, it will help keep the drippers flushed and the soil moisture consistent so that the roots do not seek additional water.
  • For ultimate protection against root intrusion, use the new Netafim™ Techfilter, with replaceable cartridges.
What if someone damages or cuts through a section of Techline™ CV , UniTechline™ AS or TechNet™ tubing? Can I spot it right away and is it easy to fix?

If tubing is accidentally severed, it is easy to tell because a puddle forms directly overhead. To repair a length of tubing you would simply cut out that section and attach a new section with barbed fittings. Other than a knife, no tools or glue are needed.
Fittings are available in a wide range of sizes to suit all Netafim™ dripperline models.
