W-Liner | Water

After trenchless rehabilitation with the W-Liner, pressure pipes can once again transport drinking water and other types of water safely and without loss.

For application in the water sector, the inner and outer layers of the liner consist of polyethylene (PE).

The W-Liner satisfies the highest requirements for drinking water and is certified in accordance with globally reputable standards such as KTW-BWGL, DVGW Technical Standard W 270, ANSI/NSF/CAN 61, BS 6920, AS/NZS 4020 and many more.

The Primus Line W-Liner is ideal for:

Drinking water
Fire water
Industrial water
Sea water
Process water
Residential wastewater
Industrial wastewater
Treated wastewater
Brine

Other media only after detailed examination and approval by our technical department.
