Good for the environment and the wallet

Saving money while doing something for the environment: this is possible with the use of reclaimed water. Reclaimed water refers to hygienically safe water that can be used in residential, commercial and industrial facilities for applications that do not necessarily require potable water.

Reclaimed water can be extracted from grey water (for example, bath, shower, and hand washing water), as well as rainwater, thus significantly reducing the consumption of potable water. It is important to have a piping system tailored to the particular composition of this process water.

With aquatherm lilac pipe, we offer a piping system that is ideal for the piping of rainwater and greywater utilization plants. Thanks to its product properties, a long-lasting and secure connection between the usage tank, pump, and delivery point is ensured. The reclaimed water can be used, among other things, for toilet flushing, washing machines, cleaning, or watering plants or lawns. Reclaimed water systems are particularly profitable for large hotel complexes, public buildings, and commercial and industrial enterprises, and installations in private households have become increasingly popular.

Product benefits

aquatherm lilac pipe


  • corrosion resistant

  • high durability

  • high flow rate

  • heat fusion delivers virtually leak-free connections

Further information


aquatherm pipes and fittings are connected by heat fusion, which creates a homogeneous, cohesive unit with no leak paths. Heat fusion connections are stronger than the pipe itself, providing lasting safety at these critical points of a piping system. A properly executed aquatherm fusion creates a permanent leakproof connection.

Depending on the dimensions of the pipe, socket fusion, butt fusion or electrofusion is used.
