Septic Systems treat underground sewer water for reuse. The function of septic system is to take waste water from households to disposal fields. Septic systems are more cheap than the disposal systems which are found in rural.
A septic system is simple in design and this make them less expensive in installation and maintenance. There are two main parts in a septic system, the drainfield and the septic tank. Concrete is used to build the waterproof septic tank and the tank contains a pipe for letting in water and another for letting out water. Wastewater is conveyed from home to the septic tank through the sewer pipes. This system uses a simple mechanism. For some long enough time, the dirty water is stored in the septic tank which allows decantation to separate the solid from the water. A series of trenches form the standard disposal field. Seperation of the rows of trenches is made using sand and gravel. From the surface, it is made to go a depth of about three feet. Drain pipes with holes run all over the trenches so that the wastewater is distributed evenly.The water is then distributed in the field using drain pipes which are laid all over the field.
The solids which then remain in the septic tank are pumped out. The tank is cleaned in a regular basis following some frequency which is controlled by some factors. One factor is the number of people in your home. The volume of wastewater generated from the home. And the amount of solids available in the wastewater.Then the volume of waste solids in the water.
Pumping of some tanks may be after one or two years. While ten to twenty years is the time others usually take. This depends on the wastewater accumulation. An odor free tank is usually made of fiberglass or concrete. This can make it last for more than fifty years. Septic tank can survive without maintaining it. This forces one to observe the rules to ensure its functional life is protected.
Failure to the system is displayed by some signs. These are. Waste pipes being unable to carry waste from the household. The wastes in the tank show whether the waste pipes are in good condition. Outlets or inlets being broken or deteriorated lead to the whole system failure. The wastes of the tank oozing from it to the nearing surroundings.
Septic systems can also be taken care of following the ways provided.Ensure that the surface above the system is unpaved. It should also be clear and not obstructed. No planting of trees and shrubs in this area. This is because the shade could destruct evaporation. Hard surface should not be used to cover the surface of the absorption area. To prevent erosion and take care excess water, grass is mostly used. Do not let the runoff water into the area, hence should direct it away.
