4. Design of the waste water system
4.1. Installation and layout principles for waste
water drainage systems
The technical aspects of waste water drainage systems have
been regulated in Europe for some time by an extensive set
of standards established in the course of ongoing European
harmonisation, started in 2001 with DIN EN 12056 (“Gravity
drainage systems inside buildings”).
This European drainage system standard consists of five
parts
Part 1: General and performance requirements
Part 2: Sanitary pipework, layout and calculation
Part 3: Roof drainage, layout and calculation
Part 4: Waste water systems, layout and calculation
Part 5: Installation and testing, instructions for operation,
maintenance and user
May 2008 saw the publication of the updated version of DIN
1986-100 “Drainage systems for buildings and provisions
for private ground [...] in relation to DIN EN 752 and DIN EN
12056”.
This standard contains additional technical requirements for
drainage systems, based on the earlier German standard DIN
1986, Parts 1+2, which were not incorporated into the DIN EN
12056 set of European standards.
The current version of the standard (from 2016) has been
reorganised into key points for better readability, including,
for example:
Basic requirements for the design and completion of
waste water and rainfall drainage systems
The installation of pipes inside and outside buildings
Requirements concerning the quality and quantity of
waste water
Backflow prevention
Sizing of waste water and rainfall drainage systems
DIN 1986-100 is therefore an extension of European waste
water regulations for application in Germany, with uniform
technical provisions for the design, construction, operation
and maintenance of drainage systems used for the disposal of
waste water in buildings and on private property.
For the sake of completeness, we also include other parts of
the above-mentioned DIN 1986.
Part 3:
Specifications for service and maintenance
Part 4:
Fields of application of sewage pipes
Part 30:
Maintenance of waste water drainage systems
