Bioline® Dripline

The world’s most advanced continuous self-cleaning, pressure-compensating dripline for wastewater.

Netafim Bioline® dripline delivers effluent into the soil with great precision, ensuring that the effluent does not flood an area or become exposed to people or animals. By distributing the effluent into the ‘biologically active soil horizon’, we not only allow the soil to break down the effluent, but we also allow plants, trees, bushes and grass to use it, along with its nitrogen and phosphorus content – two of the three ingredients in fertilizer.

This ecologically sound process helps protect against the contamination of lakes, rivers, streams and drinking water sources, it prevents objectionable odors, and it provides an important benefit – the “wastewater” is no longer “wastewater." It is reusable, renewable and beneficial water that becomes a supplement to or replacement for an irrigation system.

Why Bioline® Dripline

Bioline is a state-of-the-art drip dispersal tubing that is manufactured specifically for wastewater applications. While Netafim manufactures hundreds of types of dripline, including non-pressure compensating dripline, the features and proven performance of Bioline make any reliance on non-pressure compensating driplines unnecessary. Why use only PC Dripline? The fast answer about only using pressure compensating dripline is:

  • Predictable
  • Forgiving
  • Easy to design with
  • Provides a continuous self-flushing feature
  • Provides very consistent flow over time

How Bioline® Dripline Works?

Bioline® dripline is comprised of highly sophisticated emitters mounted inside flexible polyethylene tubing. Each emitter delivers a slow, precise amount of wastewater into the soil. Thanks to the “pressure compensation” feature built into each Bioline® emitter, the delivery of effluent is very well-balanced in the area, regardless of the length of dripline or the property’s topography. The result? Instead of disposing of the wastewater, and the associated issues of surfacing and pollution of nearby bodies of water, the
wastewater is dispersed evenly into the soil, providing not only important additional treatment but providing for beneficial reuse of the nutrient-rich water by the landscape.

The system designer and installer match the right Bioline® to the individual design, thus creating and maintaining the perfect environment for further treatment and beneficial reuse of the effluent. Netafim Bioline® is used with confidence in virtually any soil, topography or climate; because the area does not need to be dug up during installation with heavy equipment, landscape disruption is minimized.

Product Advantages

  • Built-In Physical Root Barrier – drippers are protected from root intrusion without the need for chemical protection. Water exits dripper in one location while exiting the tubing in another.
  • Three Dripper Flow Rates – provides the broadest range of flow rates available. Allows the designer to match the dripline to any soil or slope condition.
  • Bioline Tubing is Completely Wrapped in Purple – the complete tubing is purple, easily identifying it as a non-potable, regardless of how the tubing is installed.
  • Antibacterial-Impregnated Drippers – prevents build-up of microbial slime.
  • No Special Storage Requirements – does not degrade if stored outdoors.


  • Typically installed following a treatment process
  • Can be used with domestic septic tank effluent with proper design, filtration, and operation
  • Reuse applications including municipally treated effluent designated for irrigation and other disinfected and non-disinfected water sources
  • Can be used subsurface – Bioline can be installed on-surface, undercover or subsurface.
  • Allows for development and building in locations previously unsuitable
  • Ideal for difficult site conditions such as clay, shallow soils, steep slopes, or high water tables
  • Ideal for small lots
  • Ideal for sites near bodies of water and other environmentally challenging areas
  • Can be an important part of any ‘green’ construction project
