Advantages Of Using A Septic Tank
Have you ever thought that where does the water go that is used in flushing toilet, washing utensils, hands and in other works. This water goes for re-treatment and recycling in a septic tank.
A septic tank receives the waste water that comes from regular use of household plumbing. This tank is made of steel or concrete body and is rectangular in shape. The tank can contain 4,000 liters (1,000 gallons) of water at a time. This tank receives waste water from one end and delivers treated water from another end.
All the waste water from your home goes out through a sewer line to the septic tank. In septic tank the water is divided into layers depending on the weight of impurities and water.
Septic tanks develop a layered look. Scum floats on the top to form the top layer. Sludge settles at the bottom to form bottom layer and partially treated waste water is in the middle and form middle layer. The bacteria in the tank attack on the waste material and split it into non harmful compounds. The chemicals such as nitrogen and phosphorus in water can work as fertilizers.
What happens with this treated water? The treated water goes to drain fields where the oxygen and organisms present in soil can decompose the remaining impurities of water. The water can be used by plant roots or can be stored as ground water.
The rate of filtration and absorption of water is little slow. This rate is directly proportional to ground size. If the ground is big, water will be absorbed faster and vice-versa. At places, where the soil is not very porous, the drain field has to be much bigger.
A septic plant should be big in size. If the septic plant will be small then waste water will come into the tank very often and water in the tank will not get time to get filtered properly. In this scenario, some of the solid particles can go to the drain field and will affect the environment.
The force behind the septic system is gravity. Waste water from homes goes to septic tank because of gravity and from septic tank to drain field. If you want to add years to the septic tank then stop throwing solid and non-degradable waste into the drains. Become environment friendly.
