TEPPFA - FAQ Sewer in Civils

The versatility of plastics can meet almost any requirement from designers and customers. Plastics are lightweight and durable and their versatility in colour gives tremendous advantages. Colour plays a vital role in the sewer pipe market as a means of easy identification. For example, in the US sewer pipes are green. In Europe waste water and rainwater pipes are terracotta, light grey or black, green. Potable water pipes are blue, dark grey or with blue striping and gas pipes are yellow/yellow striping.

Whatever the application, the colour has no negative influence on the technical and chemical properties of the plastic pipes and fittings.

Colour coding of underground pipe systems is the easiest and most simple way to avoid costly mistakes during installation or repair. In this respect plastic sewer pipes can be easily coloured to conform to the national pipe identification standards.

Some plastic pipes have a different, light colour on the inside of the pipe making them easy to inspect by use of TV pipe inspection.
