Mound and Conventional Septic System Costs

Mound and Conventional Septic System Cost

A toilet equipped with everything you need is one of the first signs of civilization. It is not enough to just have the room, because the domestic water cannot be drained anywhere. And the septic tank is one of the most used sewer systems in regions where there are no central sewage networks.

Unlike the latrine and the dump, the septic tank is an ecological and modern solution, which can minimize the elimination of household waste, but also water losses, because the filtered water, resulting in at the end of the treatment process, returns back to nature.

How much does the mound septic system cost compared to the conventional septic system?

Advantages and disadvantages of a conventional septic system

Septic System Mound and Rock bedA conventional septic system is made of a drain field and a tank. In the tank, the solid waste is separated from the liquid waste. After that, the liquid goes through the drain field and filters into the soil.

Advantages

Diversity: There is a large variety of conventional septic systems you can choose from, like stainless steel, aerobic, fiberglass and concrete septic systems. This diversity helps you choose the best possible systems to respond to your needs.

Eco-friendly: These types of systems are better for the environment because they don’t use any power source or chemicals to break down waste.

Cost: Compared to the mound septic system, conventional septic systems cost less.

Disadvantages

Rust: If you don’t maintain it properly, the piping of conventional systems tends to rust. In case your pipes become corroded, most probably they will collapse and cause leaks of the septic system.

Ruptures and leaks: You have to take action as soon as you see there are any problems with the busted pipes or the leaks. This may result in major problems for your septic system and costly repairs. Common causes of ruptured pipes are the roots of trees and digging.

Buildup: The sewage buildup may be a real problem for your home (without mentioning the smell) and affects everything from sinks, showers, and toilets.

Advantages and disadvantages of a mound septic system

The mound septic systems require the building of an above-ground pile of sand or gravel in order to hide the septic system. So, the system’s absorption area is located above the ground and requires an electric pump to bring the waste to the mound for treatment.

Advantages

Discharge: This type of septic system does not directly discharge the liquid waste into a body of water, a hole, or a ditch.

Building: If it is done properly, the construction and installation of a mound septic system will cause minimum damage to your yard, as you will need just a little excavation.

Climate: Compared to conventional septic systems, mound septic systems experience fewer problems and work well in moist climates.

Disadvantages

Rebuilding: You may have to partially or totally rebuild the mound system if there is any amount of seepage or leaking.

Land use: In general, the mound septic systems limit land use and affect drainage patterns. In order to work properly, they need siphons and pumps.

Cost: Even though the building and installation process produces less damage, it tends to cost more than the conventional installation. Also, the cost of the system itself is higher.

Important things to consider

There are many different types of mound and conventional septic systems you can choose from. For instance, you can choose between the anaerobic and the aerobic septic systems, which refers to the type of bacteria used to break down waste.

You will have to hire a professional to inspect and pump the septic system periodically, regardless of the type of system. How often this has to be done depends on the amount of waste you need to handle and the size of the tank. However, you should have your septic tank pumped every two to three years on average.
