Septic tanks are typically used in rural areas. As an alternative to sewer systems, these large tanks help to filter solid and liquid waste. Usually, septic tanks are placed underground in the yard area adjacent to the home. The drains from the sinks, showers, and toilets all flow into this tank where they are then filtered. Heavier matter sinks to the bottom of the tank and the filtered water and liquid then exits the septic tank where it drains into a designated area. It’s an efficient way to care for the sewage from your home without having to plumb your home for sewage lines. Whether you’re looking to place a septic system in a new build or you’re trying to replace an existing system, there are a few ways you can determine which tank will best suit the needs of your family.
Size
There are many differently-sized septic tanks to choose from. The right tank size should be determined by the amount of water your family uses each day. If your family uses minimal water, less than 500 gallons, a septic tank with a 900-gallon capacity is needed to ensure that the sewage is properly processed. Families that use between 500 and 700 gallons of water should consider a tank with at least a 1,200-gallon capacity tank. In some areas, city bylaws may regulate the size of tank required at each residence.
Design
While the general ideas of septic tanks are the same, there are a few designs to choose from. If your tank is going to be installed in an area with gravel or coarse soil, a pressure-type septic system is best. For areas with rich soil or dirt, a gravity system is better. These allow streams of untreated sewage to seep into the ground, fertilizing the surrounding dirt. As with the size, there may be some restrictions regarding the type of septic system you’re allowed to have based on its location.
Pump
No matter the size or design, each septic system is designed with one of two types of pumps. A turbine pump is considered the superior of the two because they are more reliable and tend to last much longer. However, due to their increased reliability, they’re often more expensive. A centrifugal pump may not last as long, but it’s much less expensive. Both turbine and centrifugal pumps are available in different sizes, making it simple to select the one best for your tank.
There’s a lot to consider when selecting a new septic system. If you’re unsure which pump, design, and tank size are the best for the size of your home, it’s always best to consult with a contractor. Septic contractors are knowledgeable in regards to the various brands and systems available. Plus, they can help you better understand the scope of the project and what to expect during install. They may also know the bylaws and septic tank restrictions in your specific area. With their help, finding the right septic system is easy.
