Installation of a well for sewer needs

The creation of a wastewater treatment system at the dacha, where there is no centralized sewage, is very important, since the uncontrolled release of human waste quickly pollutes the soil and makes it unsuitable for growing crops. Installing sewer wells helps solve this problem. In this article we will consider the right approach to this issue.

General provisions

Wells that meet the needs of sewage can be of two types:

• Filtration. Conduct the final before entering the soil wastewater treatment using a bottom filter for the well.

• Accumulative. Sewage is collected to a certain level, after which they are pumped out by an assenizatorsky machine.

Usually the design is placed immediately after the septic tank. The cost of installing a well of one type or another is about the same. Which one to choose depends on the characteristics of your site, the possibility of its frequent pumping and personal preferences.

Tip: if the daily volume of wastewater does not exceed one cubic meter, then it is quite possible to do only one well without installing a septic tank. This will significantly save the family budget.

Assembly work

The production of such a purification plant does not require special skills and is quite feasible with your own hands.

Material selection

Today practiced the use of plastic, brick and concrete.

But the best option is to install concrete rings in the well, which provides the following benefits:

• High strength reinforced concrete.
• Ease of construction work. Unlike concrete pouring, where mortar mixing, formwork installation and reinforcement is required, the installation of ready-made products takes place here.
• Affordable price.
• Moisture resistance.
• Durability. There are no destructive processes of decay and corrosion.

Location selection

The installation of well rings should take place in a place that will meet all the necessary technical and sanitary conditions:

• Distance from residential buildings not less than 5 m.
• The presence of sufficient space for the entrance of the aspenizatorsky machine.

• The distance to the drinking well or well over 30 m.

Tip: It is recommended when laying the drain pipe from the house to the well shaft to avoid creating turns, since they can cause a congestion.

Installation

After selecting the location, an estimate is made for the installation of the well, which includes the cost of the rings, sewer pipe and gravel needed to create a bottom filter. Having bought everything you need, you can start the works themselves:

Installation Instructions:

1. We dig the pit. Its depth, taking into account the level of soil freezing, will be 2.5 m, and its width - one and a half.

1. Arrange the foundation, which depends on the type of sewer:

• For filtration create a bottom filter. We fall asleep three layers of rubble, while the size of the fraction of each subsequent should be several times larger than the previous one, and the thickness of the filling is about fifteen centimeters.

Tip: it is recommended to install a board board under the inlet pipe. This will allow impurities to be distributed more evenly and will protect the filter from leaching.

• For the accumulative we fill up 15 centimeters of gravel and pour a thin layer of concrete on top, observing the slope in the direction of the hatch to facilitate the subsequent pumping out of the drains. We are waiting for a complete freeze.

1. We mount the first ring on the cement mortar. In it we make a hole and insert a sewer pipe. The place of the joint is qualitatively cemented.

In the case of implementation of a filtration facility, we make holes with a diameter of 5 cm and in increments of 10 cm across the entire wall of the concrete product.

1. Set the following on top. In order to avoid an offset between the joints of the products, metal brackets or other locking systems are mounted.

1. From above we lay a concrete cover with an entrance opening. Such an overlap will prevent all kinds of garbage from getting inside the structure.

1. We make a hole for the exhaust pipe and install it.
2. Entrance close the hatch. Through it will be carried out repairs and pumping waste.
3. After all the components of the well in place we dig a trench for laying the drain pipe from the house or a cooperating septic tank about a meter deep.

Tip: try not to make the channel too wide. Because then you have to make a bedding, and it has the properties to settle, which can damage the pipe.

1. Along the perimeter around the filtering structure we fill it with the same material that was used in the creation of the bottom filter, around the accumulator - a clay lock.

Total

The well for sewer needs is easy to install. The main thing is to carefully follow all technical and sanitary standards. And then you will solve the problem of wastewater in your area for a long time.
