Well for storm sewer: device, types, installation

In order to adjust the water flow after rains from the site, you will need a rain well. It will help to cope with the flow of water from snow, rain and protect the soil in the garden.

The well for storm sewers

The storm sewer, or stormwater, differs by a linear and point system. Linear can be made of gutters, which are closed with special grids. Point sewage is the location of point water receivers, which can be located under the roof and collect water in storm sewer.

Well construction for storm sewers

Consider the principle of the design of this system, how it works. Since the well is intended for collecting water and transporting it for further use, for example, watering a plot, there are several options:

  1. Inspection well. It will be needed for long pipe lengths on the section, as well as if pipes from several places converge into it.
  2. Perpadny well. It is applied on steep slopes.
  3. Rotary. To change the direction of drains.
  4. Absorption well with drainage. To drain the site.
  5. Cumulative. This is a tank where water is collected from around the site, and it can be used for necessary purposes.

The number of wells in the path may vary. It all depends on the topography of the site, the amount of water during the melting of snow, soil and other factors. You can do a minimum of designs. How many wells are needed and how best to build a storm sewer system, professionals will say.

Types of storm wells

Wells for storm sewers consist of the same materials and have the same type of device. Flood racks may differ in sewer type:

  • Closed.
  • Mixed.
  • Open.

Closed storm sewers

Open wells for storm sewers look like gutters water flows. Closed stormwater inlets collect moisture through pipes under the ground, and then drained or sent for cleaning. Mixed type of stormwater may contain arched channels and closed pipe systems, but ultimately the water still gets into the reservoir where it can be used later. The final well for storm sewers must be airtight so as not to accumulate garbage.

Drainage well: plastic, concrete

Most often, wells are made of two types of materials: concrete and plastic. Order for installation can be any. Consider the advantages and disadvantages of each.

Features of drainage wells from concrete rings

The concrete drainage well for storm sewer is strong enough. It consists of a concrete slab and a ring. This material is not expensive for the price, but it will require lifting equipment. In addition, the concrete is quite durable material, but from water is destroyed over time. Prefabricated design is quite complicated to install, it is especially difficult to ensure the drilling of holes in the pipeline. In addition, you need to provide high-quality waterproofing. However, calling the masters can install a concrete structure without difficulty.

A concrete shower well has the following advantages:

  • Low cost.
  • Do not crush with soil after winter.
  • Long service life.

Of the minuses - complex installation and the need for special equipment.

A concrete well consists of rings and a solid bottom. First, a foundation pit will be dug, after which parts are lowered with the help of special equipment. Plums and nozzles should be installed in the rings. The method is very simple, but expensive to install.

The good quality of the plastic tank as a sewer well.

The plastic storm sewer well is in great demand. It is lightweight, has different sizes, which is very convenient for the buyer. Plastic is not afraid of frost, sealed, easy to use, has been serving for over 50 years. Mounted quickly, but in any case, need to calculate the size of wells.

Cons: expensive product. When heaving the soil, it is desirable to make a concrete anchor, otherwise a plastic well will be squeezed out of the soil.

A plastic well is expensive, but it is practical

Plastic rain wells are sold ready-made.It is of different volumes that need to be pre-calculated. This will be done by a specialist who will create a storm sewer project. Due to the ribs, the structure is firmly fixed in the ground and has ready-made connections. These wells may have a bottom or be without it. Installation does not take much time.

It is up to the buyer to decide which material to choose for stormwater - plastic or concrete - each has its own pros and cons.

Storm sewage device

When laying a concrete ring or polymer chamber, a sand and gravel pad is created. With a sealed well under it lay a concrete slab and coated with all bitumen. Either the drainage pad is made thicker. Even at peak loads, the stormwater must cope with the flow of water, so grates and sand traps are needed. Drop well will take the brunt of the water, so there is a need for a metal sheet. This will prevent the body from collapsing.

If the plastic system is preferred, then it fits faster. When installing 2-3 wells, you can stay on the plastic, although the concrete rings help save on the purchase. However, the savings outweigh the light weight of plastic and ease of maintenance. Decide which material to choose the customer’s case.

Stages and nuances of mounting the well

Inspection and drainage wells will be the basis of the drainage system. It is very important to correctly calculate and install them, otherwise the soil will be eroded during operation or blockages will appear. Be sure to entrust the calculation, design and installation of storm sewers to professionals to avoid the appearance of puddles on the site.

Consider an example of installing a plastic construction. For this you need:

  • Gofrotruba.
  • Plastic bottom.
  • Rubber sealing.

The choice of quality components is the key to excellent construction

The volume of the well can be any depending on the landscape and fluid intake. The largest manhole in terms of volume, and turning and accumulative slightly smaller. A concrete anchor is attached to each well. So that when the soil swells up after the winter, the construction does not squeeze it out.

All parts are very light, and in this case special equipment is not needed, which means installation will be carried out quickly and without problems. Along the perimeter of the site, plastic wells will be placed in the right places according to the pre-established drainage project. After that, the trenches are buried, and only dotted elements of the structure are visible.

How is a storm sewer useful?

The storm sewer wells can be used not only to collect fluids from melting snow and rain, but also to collect and bring tap water and sewage out of the house. But experts do not advise to combine the drainage system with the sewage system of the house, a septic tank, as the sewage treatment plant can overflow and fail. Untreated sewage can get into the ground. It is necessary to make separate conclusions and additional wells. This will help not only not to pollute the area with unnecessary drains, but also to filter water, reuse it if desired, for irrigation.

There will be no moisture on the tracks. The drainage system at the site will avoid bogging the terrain. There will be no need to look for water, if it is not nearby, for watering plants. After all, it can always be used from the storage well.
