Time To Call a Septic System Contractor
Septic systems are used when sewage plants are not available. They treat and dispose of wastewater from bathrooms, kitchens, and the laundry. These wastewaters contain germs and pollutants that must be treated for everyone’s health, and the environment, too.
There are various different septic systems, each one with its own design
A septic tank is a watertight box. It is buried deep in the ground outside the home. The tank is reinforced concrete, and can be bought from a septic system service, or from concrete manufacturers. While designed with a 1,000-gallon capacity, the size of the tank is determined by the number of bedrooms in the house.
The tank is connected to the drainfield by a pipe. A drainfield consists of two to five trenches dug into the soil. In several systems, a distribution box, or flow divider helps the wastewater to each trench. In each trench, a one foot thick layer of gravel or stone is placed around a perforated distribution pipe. Once the trenches are covered, the area should be landscaped, keeping surface waters from pooling over the drainfield.
All wastewater from the house should go into the septic tank. As wastewater goes into the tank, the heavier solids settle to the bottom, the lighter materials float to the top, and the liquids leave the tank. An outlet baffle stops solids from leaving with the liquids. The tank’s sole purpose is to keep the solids, while releasing sewage to the drainfield.
Unlike sewer systems, the septic system relies on the soil around the house to treat, and dispose of sewage. This reason alone, a septic system can only be used on soil that will adequately absorb and purify. Should a septic system be installed in soil that cannot do this, effluent will seep out. In addition to causing a very bad smell, this untreated effluent can be risky to your health.
In some cases the soils do not correctly absorb the wastewater, toilets, and sinks might not drain correctly. If the soil absorbs the effluent, but cannnot treat it, the sewage will contaminate the groundwater.
Some state laws require the soil to be evaluated by the health department, and that an improvement permit be issued before construction begins or the septic system is installed by a septic system contractor. Also, the installation must be approved by the health department before septic service can be connected to the home, and the septic system put into use.
