How much does a septic system cost? 

Septic system costs vary depending on many factors, with the results from a soil test being a significant determinant. Ultimately, the better the soil, the less expensive your septic system could be. 

Conventional septic system cost range: $10-20K

Mound system cost range: $25-40K

Other cost factors include: 

1. Existing site conditions. Is there plenty of room for our equipment to get in and out? Is there ample space 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 for installing your septic system. 

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 brought in. Additionally, some systems may require extra deep pipe trenches due to poor existing soil. Watch our video to see "what's in a mound" that contributes to the higher cost of a mound system compared to a conventional one. The results of a soil test help the septic designer determine how much your system will cost. 

3. The size of the tanks or leach field needed is based on the number of bedrooms in your home. 

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

Liquid observed in the drain field generally indicates that the soil absorption capability of the area is diminished and ponding is developing. Many systems begin ponding within the first few years, and this ponded state of a drain field is usually a slowly progressing condition. The estimated life of today's drainage fields under normal usage is 15-25 years, with some degree of ponding occurring during most of these years. A consistently rising level of ponding may indicate the life expectancy of a drain field is nearing its end. Sludge in a vent pipe or observation tube is an indicator of a more serious issue. 

Many lending institutions have been using the observation of any liquid in a vent or observation tube as the sole criterion 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 sale would be ensuring 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 occurs when effluent bleeds out onto the ground surface, wastewater backs up into the building (not due to plugged or broken sewer lines), or if the existing drain field was installed less than 3 feet from 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 tank pumping and maintenance performed once every 3 years. 

Older systems or households with many residents should have their tanks pumped every 1-2 years. 

Regular septic tank pumping helps maintain the proper liquid balance in your tank (liquid vs. sludge). During a routine pump, the certified pumper provides a visual inspection of the system, which can help identify potential problems.

What are the warning signs of a failing septic system? These signs may indicate that the drain field is failing: Liquid accumulating in the drain field vent or observation tubes. "Drain Back" from the field when the septic tank gets pumped. Water level higher than inlet or outlet pipes of the 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 drain fields are essential components 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, 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. However, if it doesn't need pumping, it can indicate several issues: a plugged filter, a bad pump, or a faulty 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. Currently, 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. Garbage disposals 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, while our bodies can process it within hours or days! Septic systems are designed 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 with clean pipes and lots of airflow. It takes several months before your septic system creates the 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 and bleaches that kill the good bacteria. The odor is most likely coming from a vent pipe or "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'.

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 with what is plugging it up and what to avoid putting down the drain. Additionally, conserving water can 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; and install water-conserving commodes. Repair leaking or dripping pipes, especially if you have a holding tank! Tree roots that invade your septic system can cause major damage. Keep trees away from the leach field, and plant trees with aggressive roots, such as willows, 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, as they will quickly fill and clog your septic tank. Ask about getting a filter installed to help manage waste. Using a lint trap on your washing machine discharge can also help. It’s important not to overuse heavy cleaners, especially those containing bleach, as they kill beneficial bacteria needed in the septic tank. This bacteria helps break down effluent solids quickly, which can reduce septic system costs over time. Avoid pouring hazardous chemicals down the drain, as they can harm your septic system and eventually contaminate groundwater. Additionally, do not flush prescription drugs (solid or liquid) down the toilet or drains, as they can also find their way into the groundwater. Remember, never enter a septic tank; the gases in it are dangerous. Call a licensed pumping company for septic tank pumping as required.
