How much does a Septic System Cost?

Septic System costs vary depending on many factors.  The results from a soil test is a big factor in determining how much your system will cost.   Ultimately, the better the soil the less expensive your system  could be.

Conventional Septic System Cost Range: $7-12K

Mound System Cost Range: 15-25K

Other Cost Factors Include:  

1.  Existing Site Conditions.  Is there plenty of room for our equipment to  get in and out? Is there plenty of room to stockpile stone, dirt etc.   Are there trees that need to be removed?  Where are the overhead and  underground utilities located? Generally, the larger the area we have to  work with the smoother the process.

2. Some sites might  require us to haul in extra fill.  Mound Systems cost more than  conventional systems because they require additional truckloads of sand  and stone to be hauled in.  Also, some systems may require extra deep  pipe trenches because of poor existing soil.  Watch our Video to see  "what's in a mound" that makes a mound system cost more than a  conventional. The results of a soil test help the septic designer  determine how much a system will cost.

3. Size of tanks or leach field needed (systems are sized according to how many bedrooms the home has).  

What if liquid is observed in the drain field vent or observation tubes?

Liquid  observed in the drain field usually indicates that the soil absorption  capability of the drain field is reduced and ponding is progressing.   Many systems begin ponding within the first few years.  The ponded  state of a drain field is usually a slowly developing condition.  The  estimated life of today's drainage fields under normal usage is 15-25  years.  The drain field is ponded to some degree during most of these  years.  A consistently rising level of ponding is a possible indicator  as to the life expectancy of a drain field.  Sludge in a vent pipe or  observation tube is an indicator of a more serious condition.

Many  lending institutions have been using the observance of any liquid in a  vent or observation tube as the sole criteria for rejecting a septic  system from a proposed sale or purchase of a home.  As noted above, this  is a subjective and inaccurate conclusion.  A more reasonable condition  of a sale would be to make sure that there is a suitable replacement  drain field area available for the future if, and when, the existing  drain field fails.  Technical failure of a septic drain field is when  the effluent is bleeding out onto the ground surface, wastewater backing  up into the building (not due to plugged or broken sewer lines) or the  existing drain field was installed less than 3 feet to a saturation  zone, groundwater, bedrock or impervious soil. 

How often should I have my septic tank pumped?

Ideally,  Septic tanks should be pumped when they are 1/3 full of scum and  sludge. County code requires you to have your septic pumped/maintained  once every 3 years.

Older systems or households with many people residing should get the tank pumped every 1-2 years.

Regular  septic pumping helps maintain proper liquid balance in your tank  (liquid vs. sludge). During a routine pump, the certified pumper gives a  visual look over the system.  It can help identify potential problems.​

Installing a filter can prolong the life of your septic system.  Filters have been mandatory in all new systems since 1999.

**By Cleaning your filter often, you'll be familiar what is plugging it up and what to avoid putting down the drain.

Conserve  water to reduce the load on the septic system. For example, do laundry  throughout the week instead of all at once; use flow reducer nozzles on  showers; install water-conserving commodes. Repair leaking or dripping  pipes. Especially if you have a holding tank!

Tree roots that  invade your septic system can do major damage. Keep trees away from the  leach field. Trees with aggressive roots, such as willows, should be  planted even farther away.

A soggy drain field can't handle waste  effectively, so design landscaping, roof gutters, and foundation drains  to divert excess water away from the septic system.

Never flush  cat litter, disposable diapers, sanitary napkins, tampons, paper towels,  facial tissues, coffee grounds, cigarette butts, or similar items down  the toilet. They'll quickly fill and clog your septic tank. Ask about  getting a filter installed.

Use a lint trap on your wash machine discharge.

Do  not overuse heavy cleaners, especially those containing bleach. They  kill beneficial bacteria needed in the septic tank.  Bacteria process  helps break down effluent solids quickly.

Do not pour hazardous  chemicals down the drain. They can harm your septic system and will  eventually find their way into the groundwater. 

Do not flush  prescription drugs (solid or liquid) down the toilet or the drains.   They eventually find their way to the groundwater. 

Never enter a septic tank. The gases in it are dangerous. Call a licensed pumping company to empty the tank as required.

These signs may be indicators that the drain field is failing:

• Liquid accumulating in the drain field vent or observation tubes.
• "Drain Back" from field when septic tank gets pumped.
• Water level higher than inlet or outlet pipes of septic tank.
•  Plumbing backups.
•  Grass in the yard growing faster and greener in the area of the drain field or tank(s).
• Soft or mushy ground in the area of the drain field.
• Sluggish toilet flushing.
• Septic pump runs constantly.
  

What is a drain field?  (Leach Field)

Septic  drainfields are used to remove contaminants and impurities from the  liquid that emerges from the septic tank.  This is typically done by  burying perforated pipes in trenches and allowing the liquid to leach  out and the surrounding soil absorbs the unwanted waste. Another term  for this is a leach field.

What if my septic alarm goes on?

Typically,  the alarm means there is a higher level of effluent than should be  within the tank.  But if it doesn't need pumping, it can mean a number  of things: Plugged filter, bad pump or a bad switch. Make sure all  related breakers are turned on or reset in the basement.  If it doesn't  turn back on, call us!

The alarm doesn't necessarily mean you need a pump, it most likely means you need us to troubleshoot it.

Should I add anything to my septic tank - like those commercials recommend?

Biological  and chemical additives are not needed to aid or accelerate  decomposition.  At this time, there is no conclusive data to support the  effectiveness of enzymes or any chemical treatment to rejuvenate a  failing drain field. Some  products are approved by the State of  Wisconsin if they do not harm the soil absorption area or groundwater.  

A septic system is built to take care of itself (unless it is failing).

Can garbage disposals be used with septic systems?

Yes,  But use it wisely. They can double the amount of solids added to a  septic tank. Try to avoid grease or slowly biodegradable products such  as peelings and bones .  Food that is not digested takes years to break  down. Our bodies can do the process within hours or days!  Septic  systems are built for body waste.   Consider installing a  top-of-the-line disposal, which will grind waste into smaller particles  that break down more quickly when they reach the system.

We just had a new septic system installed. Why do I smell a strong odor coming from it?

​​Your  septic tank has a fresh start; clean pipes and lots of airflow. It  takes several months before your septic system creates an environment it  was meant to have... An environment where the “good bacteria” (pee  & poop) is doing its job.  Natural Enzymes will eventually break  down the scum, and bacteria will eventually break down the sludge.  To  speed up this natural process, you can avoid using too many household  cleaners/ bleaches that kill the good bacteria.  The odor is most likely  coming from a vent pipe "vent stack" on top of your roof.  There is a  carbon filter you can purchase and install to treat the smell.  One on  Amazon has great reviews: Made by Sweet Air. ​
