figure 2 is a longitudinal section of the tank for the accumulation and storage of surface, storm and industrial water.

The reservoir for the accumulation and storage of surface, storm and industrial water consists of a foundation pit 1, the bottom and side walls of which are covered with a protective underlayer 2. A protective polymer layer 3 is laid on the protective underlayer 2, over which perforated drainage pipes 4 and filled with a layer of gravel 5. On the layer of gravel 5 there are modular block structures 6, which are installed in layers to the top of the pit tank 1 and are closed by the underlying layer 7. On the underlying layer 7 and the free edges of the polymer of the impermeable membrane 3, perforated air ducts 8 are laid and filled with a granular backfill 9, on which a hard coating is applied 10. Moreover, the modular block structures 6 are made in the form of storm water accumulators, from which a rigid frame of the foundation pit tank 1 is collected. In this case, the protective underlayer 2 made of non-woven geotextiles, and modular block structures 6 are made in the form of volumetric polymer solid blocks of a vertical tubular structure, the top and bottom of which are covered with a protective layer of geotextiles, and which are dnaznacheny for accumulation and storage of surface water, storm water and industrial water. The underlying layer 7 under the air ducts 8 is made of non-woven geotextile.

A reservoir for the accumulation and storage of surface, storm and industrial water is made as follows.

The reservoir capacity is performed in the form of a pit-tank 1. In the pit prepared in the ground, waterproofing is made, for which a protective-underlying layer 2, which is made of non-woven geotextile, is laid on its bottom and side walls. On the protective underlayer 2 lay a polymer impermeable membrane 3, through which form a closed cavity. After laying, the remaining parts of the panel of the polymer impermeable membrane 3 are temporarily fixed along the edges of the excavation tank 1.

Then, perforated drainage pipes 4 are mounted on the bottom of the excavation tank 1 over the laid polymer impermeable membrane 3, which are then covered with a layer of gravel 5.

And the filter material with which the reservoir is filled, namely, the foundation pit tank 1, is made in the form of modular block constructs 6, which are installed on the gravel layer 5 and use them as filter material and as storm water storage devices. Modular block structures 6 are installed in layers to the top of the pit tank 1 and cover them with a bedding layer 7 and the free edges of the temporarily fixed sheet of polymer impermeable membrane 3, onto which perforated air ducts 8 are then laid and filled with granular backfill 9. They are laid on top of the granular backfill 9. Coating 10 for use as a pedestrian zone or roadway. Moreover, by means of the assembled modular block constructs 6, a rigid frame construction of the pit tank 1 is determined.

Modular block constructs 6 are made in the form of volumetric polymer solid blocks of a vertical tubular structure, which are covered with a non-woven geotextile on top and bottom. They are intended for the accumulation and storage of surface, storm and industrial water.

The layer 7 underlying the air ducts 8 is made of non-woven geotextile.

A reservoir for the accumulation and storage of surface, storm and industrial water as follows.

Melt or surface water or storm water during rain enters the water supply wells (not shown in the drawing), from which water flows into the perforated drainage pipes 4, and from them into the pit-tank 1 through the drainage holes of the perforated drainage pipes 4 under pressure the incoming water and sent to the modular block 6, laid along the bottom of the pit tank 1. Since the modular block 6 is made with through holes, forming channels, water under pressure rises along these holes To the canal channels, they occupy a certain level depending on the amount of precipitation or received surface water. The water entering the reservoir is held and stored in the channel openings of the modular block constructs 6 until water 1 enters the foundation pit tank after the next rainfall. And they are stored in it until the maximum level is reached, after which water is pumped out by means of a pump, freeing up the necessary volume for the next portion of surface water.

At the same time, the incoming water passing through a protective layer made of non-woven geotextiles is partially filtered from impurities. Therefore, at the exit, when pumping water, they come out purified.

Using the proposed technical solution allowed us to create an inexpensive and simple device for the accumulation and storage of surface, storm and industrial water using light, affordable and inexpensive modern materials using the simplest technology. The inventive design allows you to store large amounts of storm water, protects roads, sidewalks, technological sites and other asphalt pavement from erosion and destruction, captures floating pollution, allows the prevention of erosion and energy loss. Relatively cheap and easy to install system. Thanks to a high porosity ratio of 95%, it provides maximum efficiency and requires virtually no maintenance.

The proposed tank is easy to operate and provides reliable operation of the rain sewer system of cities and industrial sites.
