Sewage treatment facilities for economic and domestic wastewater are a complex of engineering facilities aimed at removing pollutants contained in domestic wastewater.

Urban biological treatment facilities are a strategically important object in the city's infrastructure, which helps to ensure a decent level of socio-economic development and maintain a favorable ecological situation in the region.

Local treatment facilities are low-efficiency wastewater treatment facilities, as a rule, supplied complete by the manufacturer, which have the appropriate certificates. They are usually used to clean the drains of cottage villages, small rural settlements, and small industrial enterprises.

The composition of treatment facilities in each case is individual and requires a thorough engineering approach by specialists.

The hydraulic scheme of the facilities is calculated on the basis of the analyzed site for the placement of treatment facilities, taking into account the relief of the area, this is one of the most important stages, since one of the main items of costs for the operation of the facilities is the pumping costs. When calculating, we try to perform the maximum possible number of technological processes in gravity mode. Our specialists can assist you in choosing a site for placing sewage treatment facilities.

As a rule, purified wastewater is discharged into the nearest reservoirs through a special release.

The quality of cleaning is regulated by the current legislation in the field of environmental protection.

• Town planning plan (if treatment is not planned on the territory of the enterprise)
  
• Performance or consumer (subscriber) data is required for calculation
  
• Data on the unevenness of the flow of sewage (subscriber mode of operation)
  
• Statistical data of incoming wastewater analyzes or data on consumers (subscribers) for calculation according to regulatory requirements
  
• Conditions for receiving wastewater (gravity system; pressure system, through the KNS)

• Conditions for discharging treated wastewater (discharge into a reservoir; city sewer; onto terrain)
  
• Engineering research materials (geology, geodesy, ecology, (when designing the release - hydrometeorology) (the full scope of research is required when passing the examination of the project documentation)
  
• Requirements for the breakdown into stages of construction, starting complexes, based on the gradual increase in the volume of effluents discharged from the built-up area

The main difficulties and mistakes
with independent design:

1. Lack of an agreed project of the Sanitary Protection Zone (SZZ)
2. Lack of metering devices and objective (calculated) data on the required productivity.
3. Lack of title deeds to the land.
4. Inaccuracies in the preparation of the Terms of Reference: all the necessary studies were not taken into account, the documents listed above were not taken into account.
5. The justification of the price was performed incorrectly, on the basis of commercial proposals of non-specialized organizations, without taking into account the fulfillment of the requirements of technical conditions, the need for inspection of buildings and structures, etc.
6. Surveys, research, and design are performed by different companies, which causes delays and additional work.

 Decisions from
Company "Gutman Construction":

• We will analyze the existing situation, prepare the Terms of Reference for the SZZ project. If necessary, we will execute the project of SZZ and agree on it.
• We will collect all the necessary data, make calculations and submit it to the customer for consideration. If necessary, we will temporarily install metering devices.
• We will help in the preparation of documentation, if necessary, we will include it in the TOR for design.
• We will analyze the existing situation and prepare the correct technical task.
• We will prepare an estimate for design and exploration works and surveys, based on basic price guides.
• We have considerable experience and qualifications for the organization of a full range of design and search works. Company "Gutman Construction" has SRO permits for both design and exploration work. We are guaranteed to provide a positive conclusion of the examination and support during SMR.
