How to make a closed storm shower for your site

The stormwater on the site provides the collection of water from rains, melting snow and takes it from the buildings to a specific place. Its arrangement is especially relevant for households located in lowlands, in areas that can be flooded during floods, in regions with high rainfall.

There are several types of storms. They are open, closed, mixed. A closed system is more complex than an open, but more in demand. It has special trays arranged in the ground, equipped with sand traps. Water accumulates in them, is discharged to storm wells, from where it enters the sewage system.

In the manufacture of closed stormwater, storm water inlets are arranged under pipes through which water is discharged from the roof. They are connected to channels or pipes that divert fluid outside the site.

Runways are provided with drains, having receiving wells on their sides. The same is done in areas at the entrance to the house, garage, basement - as a rule, trays are placed in such places, overlapping them with gratings on top.

All marked drainage elements must be connected by pipes to the general outflow, which leads water out of the site. In the system, it is mandatory to install sand traps that do not allow sand, stones, clay to clog pipes. Pipes, with a natural outflow of water, are laid with a slope of at least 2 cm / l.

Start the production of stormwater from the device of trenches. Their bottom should be located below the level of soil freezing by 40 ... 50 cm. It is possible to decrease indicators, but then the pipes are insulated.

For stormwater, polyvinyl chloride pipes are more suitable. Their minimum diameter is 10 cm. The location is mostly straight, if necessary, turns at obtuse angles. In the locations of the latter they arrange underground tanks for collecting water. Joints of elements are sealed, using glue, a special sealant.

At the lowest point of the storm shower, a collector pipe of large cross section is located. Pipes from all receiving devices located in the area are connected to it. The free end of the collector is discharged into a sewage pit, a sewage well. The latter option is preferable, since the water from the well can be used to irrigate the lawn, garden, plants.

Having placed all the elements, they make a trial run of the storm. During its normal operation, in the absence of leaks, trenches are covered with sand, on top with plant soil.
