Here at Miami Valley Septic Service, we get many calls with questions from our customers regarding anything from how septic systems work to how long they last. We thought it would be helpful to compile some FAQs here to enlighten you on what we do and answer your most pressing questions about septic tank systems in Dayton OH.

Q: What are the components of a septic tank system?

A: Most septic systems comprise a tank and a drainfield (AKA leach field). The septic tank contains organic matter that then separates the solids and floatable matter (such as grease and oils) from the wastewater. In conventional systems, the liquid (effluent) is discharged from the tank into pipes buried within a leach field or chambers that slowly release those liquids into the soil. This area is called the drainfield.

Q: How does a septic system work?

A: Water runs from your house via a main drainage pipe to a septic tank buried in the ground. This water-tight container can be made of concrete, fiberglass, or polyethylene, and is designed to hold the wastewater that comes from your home. In the tank, the solids will settle to the bottom and form sludge, while the liquids (scum) float to the top. Sludge and scum cannot leave the tank and get into the drainfield thanks to special compartments as well as a T-shaped outlet, according to the U.S. EPA.

The liquid wastewater, or effluent, then drains from the tank and heads into the drainfield, a covered, shallow area of unsaturated soil. Pre-treated wastewater is then discharged through pipes onto porous surfaces so that the wastewater can filter through the soil. The wastewater percolates through the soil, and eventually discharges to groundwater. Sometimes, drainfields can become overloaded, leading to flooding and the flow of sewage to either the surface or as a backup in your toilets and sinks. In that case, you would need a professional septic tank service by a qualified company immediately.

Q: How much does septic tank installation cost?

A: In 2024, a conventional septic tank system costs between $3,500 – $8,500. There are other types of systems, such as alternative ($4,000 – $15,000) and engineered systems ($7,000 – $20,000) that cost more. There are many factors that will dictate your final price tag, such as the type of system you choose, as well as the size of your home and the tank material. Septic tank prices usually come in around the $1,000 to $1,500 range for a typical 1,000-gallon tank. Your septic system installation company in Springfield will be better able to tell you a firm price when you call for a consultation.

Q: What are the different types of septic systems?

A: The size and design of a septic system will vary by home, neighborhood, and area of the country. Contributing factors include household size, site slope, soil type, lot size, weather conditions, proximity to wetlands, and local regulations. The most common septic systems include:

  • Conventional
  • Chamber
  • Drip distribution
  • Aerobic treatment
  • Mound
  • Sand filter
  • Evapotranspiration
  • Constructed wetland
  • Cluster

Q: How long do septic systems last?

A: With proper care and maintenance, septic systems can last between 20 and 40 years. Factors that play into this lifespan include usage, tank material, soil type, groundwater conditions, and frequency of regular maintenance.

Q: How often should I pump my septic system?

A: In general, septic tanks should be pumped out by a septic tank specialist every three to five years depending on usage and size. The EPA says that the average household septic system should have an inspection at least every three years by a qualified septic service expert. Factors that determine your unique pumping schedule include:

  • Household size
  • Volume of solids in wastewater
  • Total wastewater generated
  • Septic tank size

Q: What can I do to maintain my septic system?

A: There are many things you can do to ensure the longest lifespan for your septic tank system, such as:

  • Use water efficiently (high-efficiency toilets and showerheads, proper load size for washing machines, etc.).
  • Properly dispose of waste (don’t dump oil, grease, dental floss, coffee grounds, cat litter, household chemicals, etc. down the toilet or drain).
  • Maintain your drainfield (don’t park on it, plant on it, or place sump pumps or roof drains on it).
  • Get your septic tank pumped every three to five years.
