The correct answer is D. The depth of tank is kept equal to its width.<\/p>\n
A septic tank is a watertight tank that is buried underground and used to treat wastewater from a home or small business. The tank consists of two chambers: a settling chamber and a digestion chamber. The settling chamber allows solids to settle to the bottom of the tank, while the digestion chamber allows bacteria to break down the organic matter in the wastewater.<\/p>\n
The depth of a septic tank is typically 1.5 to 2 meters, while the width is typically 2 to 3 meters. The depth of the tank is important because it allows the wastewater to settle and the bacteria to have enough time to break down the organic matter. The width of the tank is important because it allows the wastewater to flow through the tank without causing clogging.<\/p>\n
If the depth of the tank is equal to its width, then the wastewater will not have enough time to settle and the bacteria will not have enough time to break down the organic matter. This can lead to problems such as sewage backups and the contamination of groundwater.<\/p>\n
