Design of wastewater system and water supply units

Each of these systems is of great importance for the normal functioning of citizens. For this reason, the comfort of the residents, as well as the livability of the apartment or private house, directly depends on the competent drawing up of the drawing.

The waste system has a special role. Some residential property owners are of the opinion that the process of implementing such a system is very simple and will not cause difficulties. However, even the procedure for preparing project documentation is considered a large, responsible and labor-intensive process. If at this stage you do not provide for all the details and make even a minor miscalculation, then in future operation it will certainly appear. There are even situations when incorrectly used sewerage symbols on the drawings will lead to the complete unsuitability of the building for habitation of citizens.

Wastewater system design

Purpose of sewerage

The main purpose of the sewer system is to remove used water and solid waste from the apartment. Often these things have a very unpleasant odor, so the design of the drain must take into account hygiene standards and rules. Due to the fact that the sewer system discharges large volumes of water, fats and solid objects, the waste system must be constructed from proven and reliable parts that perform their intended purpose well over a long service life.

In addition, it is important to remember about force majeure circumstances. Therefore, symbols on water supply and sewerage diagrams according to the drawing should be placed so that if an unforeseen circumstance arises, it is possible to urgently make adjustments to the operation of the system.

• b) list of reference and attached documents;
• c) list of main sets of working drawings;
• d) symbols;
• e) general instructions: information about the documents on the basis of which the decision to develop working documentation was made (for example, design assignment, approved design documentation);
• a record of the compliance of the working documentation with the design assignment, the issued technical specifications, the requirements of current technical regulations, standards, codes of practice, and other documents containing established requirements;
• a list of technical regulations and normative documents containing requirements for technical solutions and further work, references to which are given in the working drawings;
• the absolute elevation accepted in the working drawings of a building or structure as conditionally zero (as a rule, it is given on drawings of architectural and structural solutions);
• a record of the results of testing for patentability and patent purity of technological processes, equipment, structures, products and materials used for the first time in design documentation, as well as numbers of patents and applications for which decisions were made to issue patents for inventions used in the design documentation (if necessary);

In general instructions, you should not repeat the technical requirements placed on other sheets of the main set of working drawings, and give a description of the technical solutions adopted in the working drawings.

It is allowed to include in the main set of working drawings rectangular isometric projections of systems obtained by visualizing a three-dimensional electronic model of the systems.

* Perform if necessary.

What is the need for the existence of GOST

The design of water supply and sanitation complexes is carried out within the framework of general rules and requirements. They combine all such developments into a single system. All elements of external or internal complexes used to create sewer lines are manufactured according to a single standard. To create technical documentation, strict design rules are also required. The procedure for their creation is determined by GOST design of drawings of water supply and sewerage internal networks (abbreviated name GOST 21.601-2011). It determines the methodology for preparing working drawings or documentation for internal communications of buildings or structures for a specific purpose.

Construction work is carried out in accordance with SNiP, which clearly defines the procedure for creating all networks or communications. Design documentation drawn up in an arbitrary manner will not give a clear, accurate idea of ​​the composition of the system, its elements, and components. Technical drawing is subject to the general requirements of GOST, but the specifics of creating water supply and sewerage systems required the adoption of a separate standard for documentation. It became GOST “water supply and sewerage”. This is a common name that is used by specialists for simplification. In fact, there are two parts that determine the methodology for preparing documentation for the external or internal parts of the drainage complex. They differ significantly from each other in various ways:

• conditions ;
• composition of equipment used during construction or operation;
• general piping configuration.

It is not practical to combine the external and internal parts into a single standard. It will be necessary to constantly clarify for which areas these requirements are valid. In addition, elements located inside buildings and structures do not experience such severe loads as external lines. It is also important to take into account the framework within which these standards operate - they have nothing to do with water treatment systems, as well as wastewater treatment plants.
