DIN 1986-100 is a standard that deals with wastewater calculation in buildings. It provides guidelines and regulations for the planning and implementation of drainage systems to ensure the proper drainage of wastewater. The standard was first published in 1986 and has since been revised several times to meet current technical requirements.

The wastewater calculation according to DIN 1986-100 covers various aspects that must be taken into account when dimensioning drainage systems. These include, among other things, the calculation of the wastewater volume, the dimensioning of the pipes and the determination of the minimum gradients.

When calculating the wastewater volume, various parameters are taken into account, such as the number of connected sanitary objects (such as toilets, washbasins, showers) and their expected use. The type of building use also plays a role, since, for example, less wastewater is generated in a residential building than in a hotel or school.

The pipes are dimensioned based on the calculated wastewater volume. Among other things, the diameter of the pipes, their inclination and the maximum permissible flow rate are taken into account. The aim is to ensure that the wastewater drains smoothly and to avoid blockages.

The minimum gradients of the pipes are also specified in DIN 1986-100. The gradient is important in order to achieve a sufficient self-cleaning effect and to prevent deposits in the pipe system. Depending on the diameter of the pipes and the type of wastewater, certain minimum gradients are specified.

In addition, the standard also provides recommendations for the choice of materials for the pipes, the fastening of the pipes and the design of branches, bends and other elements of the drainage system.

Compliance with the wastewater calculation according to DIN 1986-100 is important to ensure a functioning and hygienic drainage system in buildings. Proper planning and dimensioning of the drainage systems helps to avoid problems such as blockages, backflow and odor nuisance.

It should be noted that DIN 1986-100 has been developed over time and there may be more recent versions. It is advisable to consult the most current edition of the standard to ensure that the most current guidelines and regulations are followed.

Overall, the wastewater calculation according to DIN 1986-100 provides basic guidance for the correct planning and dimensioning of drainage systems in buildings. By adhering to this standard, efficient and reliable wastewater management can be ensured.
