This document is a complementary document for the installation of ductile iron pipes, fittings, accessories and their joints, covered by EN 598:2009 harmonized standard. It is intended to describe, in a wider perspective, installation technologies, tools and pipelines particular examples, applicable for the construction, outside buildings, of:

— drainage pipeline systems;

— raw water pipeline systems;

— sewage pipeline systems;

— water reuse pipeline systems;

— pipeline systems conveying surface water (e.g. rainwater), domestic wastewater and/or certain types of industrial effluents, either in separate systems or in combined systems;

— operating without pressure (gravity sewers) or with positive or negative pressure;

— below or above ground installation types.

It also gives some site operation/site instructions for the application of fittings, intended to be used for the connection of ductile iron drains and sewers to other materials as plastic, concrete, vitrified clay, etc.

This document is not intended to cover:

— hydraulic design of drains and sewers systems outside buildings. For this purpose, EN 16933-2 applies;

— construction and site testing of drains and sewers. For this purpose, EN 1610 applies;

— trenchless construction and testing of drains and sewers. For this purpose, EN 12889 applies.
