How to make a storm sewer in a private house with your own hands? Review and Step-by-Step Instructions + Video

Storm sewage for a private house is very necessary, because it drains rain and melt water from the house and the plot.

If you do not equip this system, then rain or melt water will accumulate in the soil, and this adversely affects the foundation of the structure.

In this article, we will consider the topic of arranging a storm sewer in a private house.

Storm drainage details

Storm drainage equipment is required to avoid this problem.

This system can be made on your own at the beginning of construction, or you can arrange it near the built house. Next, we will analyze the storm sewer device.

Structure

Trays on the surface and open gutters or closed channels , which are laid underground.

These devices drain water into special containers for the catchment area and or outside your area, for this reason they must be laid at an angle.

Rainwater is collected using special gutters, they are made of plastic, rectangular in shape and different volumes.

Install them under the drain pipes.

The pallets in front of the doors also collect water from the porch and roof. For convenience and safety, the pallet is covered with a grate.

It is also necessary to equip inspection wells in order to clean the channels of pipelines and gutters. They are equipped at the intersection of channels and at the junctions.

A collector well is needed so that water is collected in it and further filtered.

Also in this design there are sand traps, they are used to collect dirt from water and solid particles. Sand traps are installed on top of the storm sewer.

Types of storm sewers

Open

This system covers a large area of ​​the site, the open view of the storm sewer collects water from the platforms, sidewalks, paths and roofs.

An open storm sewer is a network of gutters made of metal, plastic or concrete, these gutters are located on the ground. Water, moving through pipes, enters the gutters, then flows into the sewer or special containers.

The gutters located on the surface are covered with gratings, they serve from debris and at the same time carry a decorative function.

The gutters are connected to each other with a sealant, it will not allow water to penetrate between the joints. When laying open storm sewers on your own, you must take into account the angle of inclination of each gutter.

Closed

Closed or point view. In this storm sewer, all system nodes are located underground.

That is, rain or melt water enters the water intake, and then into the channels located underground and only then into the tank or into the sewer.

A point storm sewer is more complex in the device than a linear storm sewer. This type of rainfall is installed at the design stage of your home.

Mixed

Mixed type of storm sewer has details of open and closed types.

Correct calculation of the storm sewer

In order for the storm sewer to serve you for a long time, you need to calculate the depth, volume and slope of the gutters.

The depth of the storm sewer installation depends on the cross-section of the gutter.

If the cross-section of the gutter is 0.5 m, then it is laid to a depth of about 30 cm, with a larger cross-section, the depth is increased to 70 cm.

The pipe diameter depends on the size of the slope:

• if the pipe diameter is 20 cm, then the slope will be 7 mm,
• if pipe diameter 15 cm, pipe diameter must be 8 mm,

These parameters are suitable for a closed storm sewer system.

For an open type of storm sewer, there are completely different parameters, for example, the slope will be 3-5 mm per 1 running meter of the pipe.

Where there are pipe connections to stormwater wells, the slope should be two centimeters per linear meter.

Stormwater drainage device in private household

1. To begin with, prepare trenches of the required width and depth, taking into account the slope;
2. The bottom of the trench is well tamped and a sand cushion is made, the height of which should be twenty centimeters;
3. A foundation pit is made in a predetermined place in order to later install a container for collecting water there. You can make such a container with your own hands from concrete;
4. Channels and pipes are placed on a sand cushion, everything is connected and the joints are sealed;
5. At the junctions with the collector, devices are installed to retain sand and debris, so they also make observation wells, in places the pipes have bends and in sections of more than ten meters;
6. All underground channels are covered with earth and covered with a lattice. When you equip the storm sewer, keep in mind that there should be gutters from each roof slope.

This system will save private homeowners from slush, puddles and premature destruction of the foundation.
