LUWA®
The LUWA® system allows both aeration and irrigation to be conducted through a single filling nozzle, ensuring no water enters the aeration pipes. Water and air are individually directed to the desired areas underground. The chimney effect and potential silting are largely avoided. One filling nozzle – two completely separate lines:
- Separate openings for installation become unnecessary.
- This results in significantly reduced installation and material costs.
By using the LUWA® system under paved surfaces, the number of filling nozzles is minimized. Accidental irrigation into the aeration line is thus excluded. The pipes can be installed to suit local conditions. The chimney effect is largely avoided, and with the inclusion of a siphon in the LUWA® system, it is completely eliminated. A controlled water flow prevents silting or fine particle displacement. Installation is possible under both sealed and unsealed surfaces.
