Septic tank functions as a sump and filter. It recycles sewage and makes it environmentally friendly. All septic tanks can be divided into four large groups:
- plastic factory;
- concrete factory;
- homemade;
- drain pits.
So let's look at all the options.
1. A septic tank made of concrete rings with your own hands is not always possible. For such situations, you can purchase a plastic ready-made version. It has three compartments: in the first, water settles from heavy particles; in the second, the process of fermentation under the influence of bacteria; the third allows you to purify water from salts and make it harmless to the environment.
2. If you wish, you can buy a massive factory septic tank made of concrete rings. You can also do it yourself, but for this you need concrete, reinforcement and a lot of free time. And the finished septic tank needs only to be installed, after which it will immediately begin to work.
3. Homemade options. The construction of septic tanks from concrete rings requires some knowledge. First of all, it is necessary to find out the groundwater level in order not to turn the drain hole into a well. You should also not only correctly formwork (by the way, in it you first need to provide cells for the outflow of water into the ground), but also think over the entire structure. Do not forget that a septic tank should consist of several parts, the largest of which is a sump.
4. The cheapest option is a drain pit. It is a hole in the ground to which sewer pipes have been brought . This option is the most economical only at first glance. Firstly, the pit has limited ability to absorb moisture, so you will have to periodically dig a new one or call a sewage collector to remove sewage. Secondly, allowing sewage to be absorbed into the soil without preliminary treatment, we create an environmental catastrophe in the area where we live, because we poison groundwater.
Septic tank
Septic tanks are not always made of concrete. Often, brick, glass, metal, reinforced concrete are used as the main material. If you are going to mount a septic tank made of a monolithic reinforced concrete block, then it will last a long time, despite the small financial costs. The disadvantage of this product is the complexity of installation. Nevertheless, there is still such an option: a septic tank made of concrete rings with your own hands. To make the installation correctly, you must perform the following steps:
1. Before you start digging a hole for a septic tank, you need to calculate its size. To do this, you will have to calculate the amount of water that the family uses per day. Also to this number we add the volume of water that will be consumed by guests. After making the calculations, we get the following result (approximately): an average family with five guests spends about 1800 liters. And since the water settles for a day, the septic tank should be 6 cubic meters in volume.
2. Dig a pit for sewage at a distance no closer than five meters from the house. Preferred sizes are 3x3x2 meters. To make a septic tank from concrete rings with your own hands, you need to close all the walls of the pit with reinforcement. In this case, it is necessary to install iron at a distance of five centimeters from the soil.
3. We make the formwork and fill the reinforcement with concrete, after leaving a place for windows through which water will be absorbed. You can also install a ready-made concrete block in the pit, which is made at the factory. For its proper installation, there is a special scheme of a septic tank made of concrete rings, where all the necessary details for installing the product are indicated.
