Rural houses are not frequently connected to the municipal sewage system. This implies that you’ll need a domestic water treatment facility to clean and dispose of your wastewater. There are numerous types of home wastewater treatment systems on the market, but they all essentially do the same thing: remove waste from your house, filter and treat it, and then discharge it. The costs of septic tanks are determined by their sizes and septic system types. For instance, because there will be less daily wastewater with a two-bedroom property using an 800-gallon septic tank, that sort of tank would be ideal for such a house.
There are two main septic system types available: anaerobic and aerobic septic systems. The traditional septic system is the anaerobic type, which decomposes waste with bacteria that do not require oxygen. These types of septic tanks typically cost between two and five thousand dollars to install before factoring in permit costs, piping, leach fields, and soil tests.
Aerobic systems require oxygen, which speeds up the decomposition process and produces considerably cleaner wastewater than their anaerobic alternatives. In fact, the effluent is treated so efficiently that the wastewater can be used for irrigation purposes. Anaerobic systems also use less space, as they require roughly half of the leach field surface area needed by traditional systems. These systems are much more expensive, starting at about thirteen thousand dollars.
Polyethylene or plastic septic tanks are the most affordable and lightweight option. The average cost for a thousand-gallon tank is around eleven hundred dollars, but their use can pose a number of problems. Some states in the US have even banned their installation as they are prone to cracking and leaking under pressure. This can lead to costly repairs down the line that cancel out the money saved on installation.
The traditional, middle-of-the-road option is the tried and true concrete septic tank. These tanks may still crack, due to expansion and contraction, but the cracks are less likely to be severe if they even appear at all; the concrete septic tank is a durable workhorse that costs about twelve hundred dollars for a thousand-gallon tank. Properly maintained and well-constructed concrete septic tanks can last for decades before needing to be replaced.
Finally, the premium option, costing approximately sixteen hundred dollars for a thousand-gallon tank, is fiberglass. Like plastic tanks, fiberglass septic tanks are easy to install and are much lighter than concrete tanks, but they do not suffer from the same cracking issues as either of the two septic tank types listed above. Combined with their diminished capacity for algae growth due to non-porous construction material, this option is well worth the hefty price tag.
What does this mean for me?
