Storm sewers are designed for the removal - transportation of polluted rain (storm) water coming from the surfaces of various objects of human activity (orderly platforms, roofs, etc.) to the site of treatment facilities for cleaning to regulatory requirements.

Drainage of rainwater along the streets of the sewered facility is carried out using a closed system of drains, with the installation of rainwater receivers on it to receive stormwater from the open rainwater network of the street or simply from an ordered surface. The drainage system is laid along the city roads along the shortest distances, taking into account the topography of the area, or to the sewage pumping stations or directly to the treatment facilities.

Before proceeding with the calculation of storm runoff, it is necessary to trace the networks and divide them into calculation areas (rainwater collection basins).

The routing of the network is carried out taking into account the topography of the area and the intended places of rain collector discharges by the shortest route to the nearest reservoirs or ravines after preliminary cleaning at storm sewer treatment facilities.

Specialists of Company "Gutman Construction" have considerable experience in the design of sewage networks of the most diverse throughput capacity. Our specialists are also engaged in hydraulic modeling and development of urban drainage schemes.

The accumulated experience of our specialists allows us to solve the most difficult engineering tasks in the optimal terms and to offer the customer a competitive price for design and research works.

Engineers of Company "Gutman Construction" are ready to help at all stages of decision-making, both at the stage of consideration of the concept of network construction and when considering options for reconstruction of existing networks.

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.
