Sewerage design: requirements, regulatory documents

Uninterrupted drainage of used water is an important condition for the comfortable operation of an apartment, office, warehouse or production workshop. For each specific case, communications are arranged taking into account the operating mode of the facility, its location and other factors. A mandatory stage in creating a sewerage system is design. Proper work done at this stage guarantees that no problems will arise when using communications.

Based on the method of transporting wastewater, sewer networks are divided into:

Non-pressure - gravity (laid under a standardized slope)
Pressure pumps – transporting runoff after sewage pumping stations.

Mistakes in sewer design		Recommendations of Region LLC when developing a sewerage project
	The basis of the project that will ensure the removal of wastewater from your facility is the collection of loads - the wastewater balance.		The drainage balance is compiled based on the following data: For residential buildings: the number of people, the number of appliances (shower, bathtub, ...). For production facilities, as a rule, the main costs are for technological needs and a miscalculation in this matter can jeopardize the entire investment project. For small settlements and cities, the balance is compiled according to the population size, the degree of improvement of the development and the load from industry.
	Errors in constructing hydraulic profiles of gravity sewerage pipelines (the slope or diameter of the pipeline is chosen incorrectly, the development prospects of the territories and possible connections are not taken into account) usually leads to significant capital costs for reconstruction or installation of a sewerage pumping station.		If the slope of the pipelines is not chosen correctly, then the speed of movement of the wastewater in the pipe is either too low or too high, which in the first case leads to siltation in the pipelines, and in the second case, silting and clogging of inspection and rotary wells occurs as a result of the removal of mechanical contaminants from the flume part of the well by forces inertia. Properly selected pipelines and a correctly constructed profile, if necessary, with differential wells will ensure reliable and economical operation of the system.
	When designing internal sewerage systems, one of the main mistakes is the inconsistency of solutions with adjacent communications and with suspended ceilings and niches, which leads to a violation of the design idea of the room.		Since the internal sewerage system is a gravity-flow system, preliminary routing and coordination of solutions with adjacent networks, linking with the design project, additional detailing of individual nodes allows the implementation of planned solutions at the lowest cost.
	Technical shortcomings that cause difficulties in the operation of the sewerage system: lack of reinforcement of socket connections under the suspended ceiling, insufficient number of revisions, counter-slopes, violations of the rules for installing ventilation of risers, lack of sound insulation on PVC pipelines near residential premises.		By thinking through all the “little things” at the design stage, you can avoid significant costs for operation, maintenance and reconstruction of the building’s sewerage system.

The main difficulties and mistakes in preparing for design

The main difficulties and mistakes when designing yourself (with your own hands)		Solutions LLC "Region"
	Lack of an agreed upon design of the Sanitary Protection Zone (SPZ)		We will analyze the current situation and prepare Terms of Reference for the SPZ project. If necessary, we will carry out the design of the sanitary protection zone and coordinate it.
	Lack of metering devices and objective (calculated) data on the required productivity.		We will collect all the necessary data, carry out calculations and present it to the customer for consideration. If necessary, we will carry out temporary installation of metering devices.
	Lack of title documents for land.		We will assist in the preparation of documentation and, if necessary, include it in the design specifications.
	Inaccuracies in the preparation of the Technical Specifications: all necessary research was not taken into account, the above listed documents were not taken into account.		We will analyze the current situation and prepare the correct technical specifications.
	The price justification was not carried out correctly, based on commercial proposals from non-specialized organizations, without taking into account compliance with the requirements of technical specifications, the need to inspect buildings and structures, etc.		We will prepare an estimate for design and survey work and inspection, according to reference price guides.
	Surveys, surveys, and design are carried out by different companies, which causes delays and additional work.		We have significant experience and qualifications to organize a full range of design and survey work. The Region company has SRO approvals for both design and survey work. We are guaranteed to provide a positive expert opinion and support during construction and installation work.

COST OF PROJECT DEVELOPMENT

To determine the basic (initial) cost of design estimates and survey work, Region LLC uses a time-tested method: drawing up estimates for design and survey work using reference price reference books. The estimated cost of design and survey work is a justified initial cost of work, which is clarified in the process of clarifying the scope of work and negotiations. An estimate for design and survey work compiled according to reference price reference books can serve as a justification for the price during the competitive procedure in accordance with Federal Law No. 44 and No. 223.

State regulation and recommendations

Before starting the development of the project, we recommend that you familiarize yourself with the MDS Manual 40–2.2000. This is an extremely useful collection on the development of autonomous utility networks for a private house with a large volume of requirements, definitions, mandatory and recommended system parameters.

The following may also be useful:

GOST 25150–82 - terms.
SNiP 2.04.01–85 - for the development of internal sewerage.
SNiP 2.04.03–85 - for the development of external sewerage.
SP 31–106–2002, r.5 – sewerage system for single-family houses.

In the text of these documents, you can find and clarify controversial or questionable issues that arise during the design.

Internal sewer system

Laying a sewer system in a private house
The intra-house sewer network includes one or more central vertical pipes, or risers, to which horizontal pipes of smaller diameter are suitable. Through them, wastewater moves by gravity or under the action of a circulation pump from washbasins, bathtubs, toilets, etc. After the riser, household waste flows into pipes of even larger diameter, which are connected either to the central sewer system or to a private house collection system, and possibly wastewater treatment.
