Sustainability criteria

Economically superior

Investing in ductile iron pipe system pays for itself in low installation and operating costs with, at the same time, an extremely long operating life!

Environmentally superior

Ductile iron pipe systems can be shown to produce true sustainability!

Technically superior

The technical performance of ductile iron pipe systems ensures the highest safety and reliability in all areas of the water industry!
