The level of groundwater must be determined in order to correctly select the material and construction of the septic tank. A maliciously selected septic quickly stops working, breaks down and is rarely recoverable.
The groundwater level is determined in meters from the ground surface. Here it is necessary to determine the possibility of the site for flooding, i.e. the release of groundwater to the surface or flooding the area with surface (thawed and downpour) sewage.
At the same time, it is necessary to determine the highest level of groundwater in the period of your residence, usually it is fixed in the spring during the melting of snow in the so-called high water.
To know your level of groundwater, you can by the nearest wells, shallow wells (in the passports for wells that are given out by honest drillers), reservoirs, rivers, reservoirs, sometimes along the ditches, as well as by asking local old-timers, connoisseurs or contacting local authorities.
If you have a geological study of the site, then it necessarily indicates the GROUNDWATER LEVEL and even make a forecast about the possibility of flooding your site.
If the groundwater level in your area is not higher than 2 m from the ground surface, you have favorable conditions for the construction of the treatment plant. In this case, you can apply a septic tank of concrete rings. For today it is the simplest, cheapest and at the same time the most reliable version of the sewerage of a country house.
If the level of groundwater in your area is more than 2 m from the ground, you should pay attention to sealed septic tanks. As a rule, such septic tanks are more expensive than septic rings, if their cost is very low — this should cause some concern. Usually, the low price of such products is due to the use of poor-quality material and thin walls of the construction, which often lead to irreparable damage in the first years of operation.
At a water table above 2 m above the ground, the septic tank must be sealed. Sealed septic tanks for the materials used can be divided into:
• plastic septic tanks (polypropylene, polyethylene, fiberglass, polyvinylchloride);
• metal septic tanks;
• monolithic reinforced concrete septic tanks;
The most widespread of these septic tanks were plastic ones. This is due to the availability of material and a low weight of products, which affects the cost of delivery and installation.
