Choose a septic tank for autonomous sewerage
Believe on the floor, do a similar drive yourself with two eurocubes with a sealed insert of pipe branches - an occupation for a great craftsman and optimist. Run home-grown autonomous sewer at the cottage without the correct calculation and fit the joints in three to four years, then a replacement.
What does the market offer? At first glance, quite worthy systems of biological sewage treatment, largely of the same type and working on the principle of decomposition of domestic sewage with the help of small bacteria. Microorganisms eat our dirt, produce a muddy residue that sometimes needs to be removed.
We recommend to pay attention to three models: Aster 5, ItalBio 5, Topas 5. The price of similar equipment from different suppliers bites, but remains practically stable - 70-75 thousand rubles. Look for advertising on the network, compare, buy. At the outlet from such an autonomous sewage system in a summer cottage or in a country house, we have:
- a decrease in biological oxygen consumption from 200 to 4 mg / l;
- chemical oxygen consumption is even below the norm at level 27;
- the yield of nitrites and nitrates is 2.5 and 36 mg / l, which corresponds to practically pure water, which can be drained into public sewage even without aeration.
The principle of the operation of the autonomous sewer at the dacha
Do not rush with early decisions: it has undergone no problems. First, calculate how much and what exactly will flow and dispose of near your new cottage. We recommend to divide all wastes of life into three types:
- sewage from toilet rooms: they can not be called literally hand, but we think you know the smell;
- waste water from showers, bathrooms, baths, saunas: a lot of chemistry, which can be contaminated by the surrounding nature;
- household outlets of autonomous sewer at the dacha: sinks, summer kitchens, all places where something is washed, cleaned, rinsed.
The task of your stand-alone system is to move( select the diameter of the sewer pipes), transport it, clean it as efficiently as possible( biological treatment of sewage sludge) and return to the surrounding nature water that is cleaner than the original one.
The best models of bioseptics for country houses make it possible to make sewage treatment easy and unobtrusive. The closed device, buried at the design level, collects all the impurities and, with the help of good microorganisms that consume organic matter, turns the mud into aeration water. Septic tanks of this type( Unilos, Astra, Topas, etc.) we will discuss in separate articles, but the basic arrangement of similar equipment is similar.
How to start the wiring of the autonomous sewerage networks
If you consider yourself a professional in the installation of pipeline systems and are able to independently calculate the slopes, the corners of the outlets and the local costs of a non-pressure autonomous sewage system of a summer cottage or a country house, then the flag is in your hands. Doubt, start with the main thing. The scheme for the distribution of fan tubes can not be made by any designer without the most elementary parameters:
- accurate data on the scope( costs) of your water use;
- the desired location of the bioreactor;
- characteristics of the soil, the depth of freezing and the presence of the upper aquifers( usually for the sewerage the depth of 30-40 cm is considered optimal);
- linear distances along the trace and the values of natural gradients.
We will not be original: build seriously and for a long time - call for a dacha of specialists, but carefully and with knowledge, watch their work.
