How to choose a septic tank for a private house: types,
When a person is vital, sewage is always generated. The ingress of these impurities into the environment without prior treatment is undesirable. Such liquids can cause great harm to nature and human health. But after all, without sewage systems, life can hardly be called comfortable. To improve a person’s living conditions and not to harm the environment, special devices are used - septic tanks. They clean sewage and return practically pure water to nature. Choosing a septic tank you need to take into account many nuances.
What criteria need to be considered when choosing
On sale you can find many different designs of septic tanks. And every year there are all new models. And what criteria should be taken into account when choosing a design for a country house or cottage?
- First, performance. If you make a mistake with this indicator, the cleaning will be of poor quality. The septic tank can not cope with the incoming amount of waste, which will lead to unpleasant consequences (emissions of sewage into nature, flooding of the site with drains and faults of the septic tank itself).
- Secondly, these are geological conditions at the site. Each septic tank is designed for use in certain soils and other environmental indicators. This will envy the effectiveness of his work.
- And of course, the cost. This criterion plays a big role. But here, the main thing to remember popular wisdom: the miser pays twice.
What performance to choose
This indicator will depend on many factors:
- how many people live in the house;
- what is the number of sanitary devices;
- how often guests come and more.
To take all these factors into account is a difficult task. Therefore, simplified calculations of the performance of a septic tank are used. To do this, the number of permanently living people in the house is multiplied by 200 liters (the approximate daily water consumption by one person) and multiplied by three days (to take into account the peaks of the load). As a result, we get the approximate required performance of a septic tank per day.
Of course, this figure is very inaccurate. For example, you can buy a much smaller volume septic tank to give, because here people live non-permanently. But for the main dwelling it is better to purchase equipment with a margin of productivity.
Determine the ground
The condition of the soil on the site will also affect the choice of design. The fact is that some models require the use of additional devices for the purification of wastewater.
Tip! Filtration fields or special wells can be built only on sandy or close to them soils. Of course, the aeration field on clay soils can be done. But such work will take a lot of manpower and resources. In this case, it is better to select a septic tank without the need for additional facilities.
Also advice on the manufacturer's recommendations for groundwater. Some models require their deep occurrence. Otherwise, the cleaning efficiency is significantly reduced.
Other options
On sale there are models for which work the electric power is necessary. Compressors operate on electricity, which provide the work of aerators. If you install the cleaning design at the dacha, then there is no point in choosing such a model.
Learn about the features of installation. Septic tanks can be produced from various materials. If the design itself is large in size and weighs decently, the installation will require the involvement of special equipment. This means that additional costs are inevitable.
Tip! Some models require the equipment of additional facilities for the treatment of wastewater. Fields of aeration can have a large area, which will not be on your site. This factor must be considered.
Choosing a septic tank, tip on reputable manufacturers. Acquisition of models that have been produced for a long time and have proven themselves is more practical. In addition, their characteristics and effectiveness can be easily learned from the reviews and messages that real users write on specialized forums and portals. On such sites you can get a lot of information about specific models, and make a more informed choice.
Do not forget the access roads to the installation site. Some models can work for a long time without the need for pumping sewage. But still occasionally have to resort to services assenizatorskoy machine.
Well, remember the cost. Of course, saving money on sewage equipment for a country house, which is used as a permanent place of residence, is not worth it. Comfort will depend on it.
