Introduction

Calculation and graphic work on sanitary equipment of the building is carried out by students of the bachelor's training "Construction"

The internal water supply of buildings and structures is provided for supplying water to consumers in the required amount and under the required pressure, since the presence of water in a residential building is one of the most important factors of convenience.

The purpose of the calculation and graphic work is to summarize and consolidate the knowledge of the theoretical course, as well as acquire skills for independently solving problems related to the design of internal water supply and sewerage of the building

Calculation of internal sewage system

Sewerage is an integral part of the water supply and drainage system, designed to remove solid and liquid products of human life, household and rain wastewater in order to clean them from pollution and further operation or return them to the reservoir. A necessary element of modern urban and agriculture.

Conclusion

The design of water supply systems, as well as sewerage, implies accurate calculation for each structure, the main role in which is played: the design of the building from which it was erected, climatic conditions. If we talk about residential buildings, such calculations allow:

identify all the parameters of the system, which means that apartment owners will not have to spend on additional equipment;

exclude the possibility of lowering the water head during the operation of the house and other household situations;

eliminate the possibility of untimely system failure.

The purpose of the calculation task was to acquire the skill in calculating and designing cold and hot water supply systems, as well as the internal and yard sewage system of a four-story two-section residential building.
