Wastewater technology systems without external water penetration

 

As weather conditions become more extreme, the volume of ground water will increase, exposing sewer systems to unprecedented strain. The result: 25% of wastewater is "infiltration water"4. Water treatment plants are regularly overloaded, operating costs increase and, inevitably, wastewater fees skyrocket, much to the annoyance of local residents. The answer is wastewater technology systems that keep external water out and costs within reasonable limits. The wastewater technology systems from REHAU do just that. Choosing the right system from the outset saves unnecessary follow-up costs. Because wastewater treatment is expensive. Excessive strain on the sewer system and resulting damage caused by infiltration water are to blame for this.

#expect more - The REHAU solution

We manufacture our AWADUKT PP pipes and AWASCHACHT from pure, filler-free polypropylene, PP. The types of cracks and fractures that can occur with rigid pipe systems made of stoneware or concrete are virtually impossible with pure polypropylene. Our Safety-Lock system ensures permanent seals. Even with slight deformation or bending, the pipe connection remains sealed up to 2.5 bar internal pressure.

Load-free chamber element seal

A load-free chamber element seal, combined with our Safety-Lock sealing system, ensures 100% tightness. The toothing of the reinforcement ribs keeps the chambers safely in the ground even at higher groundwater levels.

Special sealing system

We have developed a special sealing system in the connection area to ensure that our chambers are 100% impermeable to external water immediately after installation. This Safety-Lock system prevents accidental displacement of the seal during the insertion process. The position of the seals also ensures maximum safety: they sit protected in a bead and seal horizontally and radially.
