How to choose a non-volatile septic tank

No sewage system can do without a sewage treatment system. For these purposes, use special devices - septic tanks. There are many types of such structures. The choice of a particular model depends on the preferences of the owner of a private house. But if you want to get a completely autonomous sewage system, then you should choose non-volatile septic tanks. For their work there is no need to connect to the power supply. And how to choose a non-volatile septic tank, we will tell in this article.

How does it work?

In work of non-volatile septic tanks there is nothing difficult. In their design there are two cameras (but maybe more). In the first, solid particles of the pollutant settle, which are precipitated and then processed by anaerobic microorganisms (that is, without air access).

Tip! The formed sludge must be periodically pumped out of the septic tank. Manufacturers of some models allow its use as a fertilizer for home garden or garden.

Then the effluent, but without the large and solid particles of the pollutant, flows through the piping system into the second chamber. Here aerobic bacteria come into play. They recycle the remaining organic pollutants.

The drains can then pass through several more chambers or filters. Already purified water enters the ground or in the field of tertiary treatment. This process can take up to one and a half months. Everything will depend on many factors. This is the ambient temperature, quality, and components of the waste, and the properties of the microorganisms used. But the main thing is that this does not require the participation of a person or the use of any additional energy-consuming devices. All processes are completely autonomous.

Advantages and disadvantages

Septic tanks operating without electricity consumption, and these include septic tanks Breeze, Bars Bio, Cedar, Tank, Triton and others, have a number of undeniable advantages. Namely:

• full autonomy. There is no need for electricity supply and careful maintenance of the equipment;
• low cost. Due to the lack of sophisticated electronics and various pumps, the price is relatively low;
• ease of installation and operation. All work can be done independently without the involvement of specialists and special equipment. And care will consist only in periodic cleaning of tanks from accumulated sludge and the addition of biologics.
• reliability. As there are no difficult devices, the septic tank serves reliably and long.

It is convenient to install such constructions at summer cottages, where people live only periodically, and there are interruptions in electricity. Non-volatile septic tanks do not need to be preserved for the winter period.

But there are some minor flaws. The very first is an insufficient wastewater treatment. After passing the sewage through a non-volatile septic tank, up to 60-70% of sewage is removed. But if you use additional filters and fields after purification, the water at the outlet will be much cleaner.

Also to the disadvantages include the need to resort to the services of assenizatorskaya machine. The pumping procedure should be carried out 1–2 times a year. Although, if you buy a pump for pumping sewage, then the cost of the service to remove accumulated sewage will not. Also on sale are models that do not need such frequent pumping of accumulated impurities. Cleaning such a septic tank occurs no more than once every 5–10 years.

Selection features

Choosing a septic tank it is necessary first of all to know the necessary volume. For this, the amount of waste discharge per day is calculated and this number is multiplied by three. The amount of waste will depend on the number of people living. As a rule, one person per day uses, on average, about 200 liters of water. Multiplying this figure by the number of tenants, we get the daily volume of wastewater.

Tip! If people live in the house permanently, then the volume of septic tanks should be calculated from the above formula. Well, if the tenants are periodically (for example, at their summer cottage), then the device may be smaller. Here everything is determined experimentally. But it is better not to save.

Also when choosing a tip on the material from which the construction is made. Concrete, plastic or metal can be used here. If we talk about the first option, then it can be a structure embedded in a formwork, or a septic tank made of concrete rings. Both options can be done without the involvement of technology. But if the rings are large, then it is unlikely to be able to establish them yourself.

The best option is a septic tank made of plastic. This material is lightweight, and all installation work can be done manually.

If you are going to install a non-volatile septic tank on your site, you should not think that it will be completely cheap. A quality device can cost a lot of money. But as a result, you will receive a fully autonomous sewage system and will not spend money on electricity consumed by the sewage treatment plant. Yes, and the septic tank will serve for decades.
