Concrete septic tank cost must be considered carefully before people install a septic system in their house. We can ensure that installing the septic system is important, but people have to count on anything.
This way, they can plan the system to be installed properly in the household. Some factors can affect the cost of building the septic system.
Factors that Influence the Cost of Septic Tank System Building
Tank
Of course, the first thing that will affect the cost of installing the septic system must be the tank. Most tanks are made of concrete. However, some other tank options, such as fiberglass, steel, and polyethylene, can also be chosen.
When people want to build a precast concrete tank that can hold about 1,000 gallons, it can be a great choice for system installation in a house with three bedrooms. The cost will be about $600-1,000.
Drain Gravel
The cost of concrete septic tanks is not the only thing people should count on when installing a septic system in their households. They also have to consider other factors, including the drain gravel.
We can ensure that gravel trenches are an essential part of the drain field. A drain field can be made from a 36-inch-wide trench containing gravel 10-12 inches in size.
The installation will be made 12-36 inches from the ground’s surface. For a ton of gravel, people should prepare about $12-30 per ton.
Pipes and Risers
The pipes will be installed to carry wastewater from the house to the septic tank and from the septic tank into the drain field.
The size and design of the system will affect the cost because different designs and pipe sizes will have different prices. People also must not forget about the cost of the septic tank riser. It is necessary to allow access from above the ground to the tank.
Permits
How much is a septic system? Although people realize it is important, we can ensure that people will have certain worries if they have to spend a lot of money on this system. They also have to pay for the permit.
The price will depend on the location and the project’s complexity. The permit sounds expensive, but it usually comes with the inspection, so the system can be installed based on the right code.
Designs and Installations
Finally, the design and installation of the septic tank system will also be the next important factor that can influence the cost of septic tank system installation.
A soil test might be necessary to determine the soil’s drainage capability and other important things. This will affect the design and installation needs. The cost of hiring a contractor is also included in the concrete septic tank cost, so people have to count carefully.
Personal Experience:
As a homeowner who recently installed a 1,500-gallon precast concrete septic tank, I found that the cost varied significantly based on several factors. The total cost for the tank, including installation, was around $2,300. This included the necessary permits and additional costs for gravel and labor. The quality and longevity of the concrete tank made it a worthwhile investment for our family home.
