W-Liner

After a trenchless rehabilitation with the W-Liner, pressure pipes transport potable and other types of water safely and loss-free again.

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

The W-Liner satisfies the highest requirements for potable water and is certified in accordance with globally reputable standards like the KTW-BWGL, DVGW Technical Standard W 270, ANSI/NSF/CAN 61, BS 6920, AS/NZS 4020 and many others. The Primus Line W-Liner is ideally suited for potable water, brine, industrial water, sea water, sewer water and many other fluids in the water sector.

Are you thinking about using the W-Liner for other fluids than the ones listed? Please contact our engineers.
