The active subsurface irrigation

The active BLUELITE-NET system is a completely new and technically improved solution for water-saving underfloor irrigation for e.g. trees or sports fields.

It consists of 3 elements:

1 a drip irrigation TUBE

2 BLUELITE-COVER, a protective geotextile cover for the tube which distributes water into the

3 LITE-NET where it is distributed over a large area at root depth.


The BLUELITE-COVER distributes the water linearly along the irrigation tube, while increasing the water / soil contact area by a factor of 1,000 and protects the tube openings against root ingrowth and blockage caused by soil fines.

The BLUELITE-COVER for the irrigation pipe therefore has several functions:

  • protection of the openings of the irrigation pipe against ingrowth of plant roots
  • water distribution in longitudinal direction of the irrigation pipe (important for soil mix)
  • contact or water transfer to the distribution network
  • a thousand fold increase in the contact area of water with the ground
  • mechanical protection of the irrigation pipe
  • if the irrigation pipe fails, it can be replaced in-situ with a new one

Subsurface irrigation eliminates evaporation, felting and surface waterlogging, reducing the cost of surface treatment. Irrigation is possible at any time and throughout, even if the lawn is being used or mowed. Because of the open and flexible shape of the net, there is no barrier at all; it can be laid at any depth, as plant roots can easily grow through or anchor themselves around the net, thus extracting 100% of the water stored in the net when needed. Even during the growth phase or in a plant mix, the plants are optimally supplied. Compared to spray irrigation, up to 70% water is saved.

If desired, the BLUELITE-COVER can also be delivered without an irrigation pipe and other pipes can be inserted yourself.

The subsurface BLUELITE-NET system is protected against vandalism and especially indicated for the irrigation of slopes exposed to the sun. It irrigates the slope efficiently and without evaporation. Due to its open net structure, the roots can fully develop without encountering any obstacle, preventing the creation of a sliding layer and even increasing the slope’s stability.


  • large area water distribution without evaporation
  • easy installation at any floor depth
  • cost-effective and durable
  • rootable water storage
  • water savings of up to 70
  • protection of the irrigation pipe by fleece coating 

BLUELITE-NET finds a completely new application for city trees: Among the disadvantages of conventional underground irrigation pipes are bad and irregular water distribution with changing soil characteristics as well as the danger of possible obstructions and an irregular as well as uneven water supply. This is why most irrigation pipes are placed on surface. But there they often suffer damages, which again leads to water no being distributed regularly.

Hence THE solution with the BLUELITE-NET system: In existing trees, the BLUELITE-RING - a fleece-coated irrigation pipe - is led around the trunk in a ring shape at a depth of approx. 5-10 cm and connected with a branch line. For new tree plantings the BLUELITE-RING is placed on a LITE-NET vegetation net. In this way the water is effectively and evenly directed to the roots.

Further advantages: No clogging of the irrigation holes by roots or fine particles. The escaping water is capillary distributed in the fleece coat and irrigates the environment evenly over a very large contact area. Protection of the irrigation pipes against vandalism and UV influence. Personnel costs and water consumption are significantly reduced.


The versatile water distributor

Our cost-effective active underground irrigation BLUELITE-AGRI, a fleece-covered hose that can also be laid in the ground without a distribution network, has been specially designed for retrofitting in existing plantations and for larger green areas and fields. The easiest way to lay it is to use devices for slotted drainage.

BLUELITE-AGRI is a cost-effective combination of a drip irrigation hose with a protective, distributing and water-storing fleece coating and is installed underground at root depth in the soil.

BLUELITE-AGRI is intended for use in existing vineyards, vegetable and fruit plantations or fields. It can also be used on any lawn, trees, bushes or in larger plant troughs.
