Factors Influencing Septic Tank Replacement Cost

Septic tank replacement cost depends on these factors:

Tank Size

The larger your tank, the more your septic installation in Sussex County will cost. The number of people using the tank will need to be factored in when considering its size, too.

House Size

The size of your house is a prime determining factor when it comes to how much a replacement septic tank will cost. A home with three bedrooms usually needs a 1000 gallon tank, which costs between $600 and $1000 dollars.

Soil Type

If your soil is permeable and can handle a drain field, your costs will be lower than they will be if you need to modify the soil or make other arrangements. We have several options when it comes to purifying your water before it reaches the water table, and these range from $6000 to $15,000 dollars, depending on type, size, etc.

Aerobic vs. Anaerobic

Anaerobic systems use certain kinds of bacteria to break down your waste, while aerobic systems use bacteria that need a pump that injects air into the system in order for them to function. Anaerobic systems tend to run $2000 – $5000 while aerobic ones are between $10,000 and $20,000.

Type of Septic Tank

A wide variety of materials can be used to make septic tanks, and your septic tank replacement cost will depend on which one you choose. Options include concrete, plastic, steel, and

fiberglass. Each has pros and cons. Plastic is usually the least expensive, then fiberglass and concrete. We don’t recommend stainless steel because it does not last for septic tanks.

Type of Septic System

Conventional septic systems are likely what you have now, if you’re replacing a tank. Alternative systems upgrade this older model to break down waste faster and move it along quicker. However, they are more expensive and, often, unnecessary

Additional Costs

There are also additional costs when you call septic companies in Sussex, NJ and talk about septic tank replacement cost. These include testing your soil, preparing your landscape, any leach field work that needs to be done alongside installing your new tank, and permits and inspections for the new parts of your system.
