Engineer Septic System Cost

An engineered septic tank system costs on average $15,000. However, factors such as site preparation, excavation and location can affect the final price. It could cost you anywhere from $7,000 to $20,000.

A soil test may reveal that homeowners are not able to install a standard septic tank due to the ground’s inability to drain. The septic tanks will force the liquid effluent into an engineered drain field. You can build the system on top of a mound drain field or near a sand-filled container that will purify the wastewater prior to it reaching the water table. A well-engineered septic system will cost between $12,000 to $15,000.

Septic tank risers provide ground-level access to your septic tanks, making it easier to maintain and cheaper. Risers, like septic tanks can also be made of concrete or plastic. Risers are often included with new septic tanks, but can also be used to replace old tanks. Concrete risers cost around $100 and are more affordable because they are heavy. Plastic risers cost around $200 and are lighter.

Although it is easy to believe that engineers can print pre-made septic systems and then charge high prices for them, there are some instances when this might not be true. The engineer has to consider many factors, including the soil type and slope, the shape and size of the lot, location of water and wetlands, and the site of any wells. Most properties have unique designs.

An engineered system will have a similar installation process.

  • You can build the pipe system by glueing together perforated and solid drain pipes according to the engineer’s design.
  • Run the pipe from the house to the tank, then to the tank, and finally to the pump (if it is installed), and to the drain field
  • For the process to move forward, wait for the approval of the building inspector
  • Use prescribed materials to cover the pipes
  • Wait for an inspector to inspect the system.
  • You can cover the drain field with the topsoil that was removed earlier and plant grass seed, or cover it with sod. Only grass is permitted because it doesn’t have roots that could damage pipes or disrupt bed materials. The grass roots and plant also wick up effluent, which promotes the drying of drain fields.
  • Wait for final inspection and approval
  • Dig the hole, place the tank in it and have it delivered.
  • Install the pump tank, pump and wiring for a raised system (subcontracted to an electrician).
  • Removing the topsoil at the drain field location is a good idea. Pile it up for reinstallation
  • Standard system: Remove additional soils from the locations indicated on the drawings.
  • You can build the drain field bed standard or raised one layer at a. with the appropriate materials, methods, and depths


How often should my septic tank be pumped?

How often should my septic tank be pumped?

Your septic tank should be pumped at least once every three to five year, or as often as necessary. The cost of a new septic tank will vary depending on its size and type. Prices for septic tanks range from $5000 to $5000. A septic tank stores and collects sewage. It is cheaper than a home sewage treatment plant. A leach field is a system that allows treated sewage water to percolate into the ground through a network of trenches and beds.

What are the maintenance costs for a septic system?

Regular maintenance is required for septic systems to work properly. There are many types of septic tanks available, including plastic, concrete and fiberglass. The cost of maintenance will vary depending on how large the system is. The size of your home, as well as the soil conditions in your region will determine the type of tank that you need. There are many types of septic tanks. Prices and treatment methods can differ depending on the factors.
