Intro to Septic Systems

Septic systems, also called septic tanks, are a method of wastewater management designed for single homes. Septic systems are not connected to public sewer systems and instead function independently. A typical septic system has two main components, the septic tank and the drain field. When wastewater flows into your drains, it continues through your pipes and into the septic tank, where it then separates into solid and liquid matter. The solid waste sinks to the bottom and remains in the tank until it is removed via pumping, while the liquid passes through into the drain field, where it is then slowly released back into the soil.

Your septic tank will need to be pumped regularly to prevent excessive sludge buildup, which can cause backups in your drains, or worse problems. Most septic systems are designed to need pumping only once every 3 to 5 years, although this can vary depending on the size of your tank and the number of residents in your home.

The capacity of a septic tank is calculated based on this formula: C = 180P + 2000 liters. In plain English, this reads, capacity is equal to 180 liters per person per day (for a year), plus an extra 2000 liters. It’s important to know that when calculating tank capacity, the manufacturers assume the number of people likely to live in a home of that size. Two people living in a three-bedroom house will likely be able to go longer between pumping because the tank was designed for use by more people; while a family of six in the same house will need to have their tank pumped more frequently.
