Design and construction of sewage pits in a private house

Sump: where to start?

Any construction, including this object as a sewer pit, it begins with a definition of its location.And here it is necessary to adhere to certain rules:

• can not place it too close to the house, the distance between these objects must be at least 5 meters;
• distance to the water intake should be 30-35 m;
• provide free entrance to the pit assenizatorskaya machine to clean it;
• bottom of the pit should be at least 1 m from the passage of groundwater;
• from the edge of the gutter to the fence - 1 m or more;
• according to sanitary norms septic tank should be no closer than 20 meters from wells with drinking water for a clay soil, 300 m - for the loamy and 50 m - sandy loam.

also important volume sump, approximate size is calculated at the rate of 0.5 cubic meters.1 on a person.But if you can, it is better to take the amount with a small margin, then you will not have to often cause the machine to pump drains.

Species cesspools and device

defined the location of the sump, you must choose the type of design that you will install.

All drives are divided into these types;

• cesspool in which no bottom;
• sealed type, is a tank made of plastic placed in the ground;
• septic tanks that have wastewater filtration system.

Sump without a bottom has a very simple design, besides it is not necessary to clean - wastewater soak the soil.This type of construction is ideal for small areas, because of its size is much smaller than all the others.

However, it is such a system should be placed as far away from drinking water wells as drains, connecting with the water makes it unfit for drinking.

sealed plastic tank buried in the soil, preventing soil pollution because drains are not able to go beyond it.As for shortcomings, such capacity requires regular cleaning, at least once a month, and it is a lot of extra costs.

Septic tanks are the most advanced and effective type of water intake, because in addition to the collection of waste, have a system for cleaning.

Sump of concrete rings in a private home: the scheme and sequence of works

This type of sump will be the best option in that case, when the amount of waste is less than 1 cubic meter.per day.Otherwise, the water just will not have time to soak in the end - the appearance of unpleasant odors and the need for daily cleaning of improvised means, such as a bucket.Such inconvenience is unlikely to enjoy the owners.However, if you do not live year-round in a private house, and inquire there only on weekends, then this type of sump will be for you the best option.

Building a cesspool of concrete rings is as follows:

• digs a pit of sufficient depth and width (guided by the number of rings);
• it spread layers of concrete rings that hold together by metal straps;
• simultaneously with angled pipe laid for the smooth flow of water;
• Inside the well pipe is put on top after the first ring;
• After this top ring mounted hatches (which in the winter is necessary to insulate);
• gap between the rings and the walls of the pit covered with earth.

Tip: If you want to slightly increase the volume sump, you can do so by increasing the diameter of the rings because the standard height - 1 m Choose the reinforced concrete ring of larger diameter, for example 1.5 m or 2 m
