Water and Sewage

Plastics for water and sewage technology, water treatment and sewage management

Plastics are the standard material in water and sewage technology due to corrosion resistance, long lifespan and easy installation. PlastShop delivers semi-finished products to water and sewage contractors, water treatment plants and municipal facilities. Our materials withstand the chemicals used in water treatment and sewage management, and have an expected lifespan of 50 years or more.

Requirements and Challenges

Corrosion resistance in contact with water, sewage and chemicals
Long lifespan (50+ years) with minimal maintenance
Weldability for leak-tight joints
Chemical resistance to chlorine, ozone and precipitation chemicals
Drinking water approval according to relevant standards

Recommended Materials

PE-HD / PE-100
Pipes, tanks and containers. Weldable, drinking water approved

PP-H / PP-C
Tanks, pipes and valves. Good chemical resistance

PVC-U
Pipes and profiles. Flame retardant, cost-effective

PVDF
Chemical resistant for aggressive process fluids

PTFE
Seals and packings in pumps and valves

GFK (glass fiber reinforced plastic, upon request)
Large tanks and containers with high strength

Common Applications

Water Treatment Plants

PP and PE for sedimentation basins, flotation plants and chemical dosing.

Sewage Management

PE and PP for sewage pipes, pumping stations and sludge handling.

Drinking Water Supply

PE-100 for drinking water pipes. Drinking water approved with long lifespan.

Chemical Dosing

PVDF and PP for dosing of chlorine, ozone and precipitation chemicals.

Why Choose Plastics

Plastics do not corrode in contact with water, sewage or chemicals. This gives an expected lifespan of 50 years or more, compared to 15 to 25 years for metal pipes. Plastics are also easier to install, require simpler tools and can be welded to leak-tight joints. The total cost over the lifespan is often lower for plastics than for metal.
