Septic Tank Cleaning Cost

• Dumping out a septic tank runs about $75 -$200 but can be $300 and up in some parts of the country, and should be done every 1-3 years depending on the size of the tank and the number of people using it, according to Laundry-Alternative.com.
• Pumping out larger tanks (1,500-2,500 gallons) can cost $200 -$350 or more.
• Installing a high-quality filter to protect your leachfield/drainfield costs about $200 -$300, according to officials in Olympia, Washington.
• Sometimes a failing septic system can be resurrected by properly pumping the tank, cleaning the drainfield lines, installing filters and a process known as fracturing the soil, which involves inserting a hollow tube into the ground and injecting a 300-pound blast of air, at a cost of $1,000 -$2,000 or more.

• A septic system has two main components, a tank and a soil absorption system (drainfield/leachfield). The tank is designed to let heavy solids settle to the bottom, where bacteria decomposes the solids into sludge. Grease and other light particles float, forming scum. The amount of sludge and scum builds up over time. Pumping prevents them from flowing out of the septic tank and clogging the drainfield/leachfield.
• The Maryland Cooperative Extension provides an illustrated explanation of how septic systems work and the Iowa Onsite Wastewater Program explains the need for regular tank pumping.
• Note: Biological additives are unlikely to be harmful, but some chemical additives that are advertised as eliminating the need for tank pumping may actually damage the septic system.
• Generally pumping out a septic tank takes around 4-5 hours of manual labor or about 2 hours with a backhoe or other equipment, according to Turtlesoft.com. This includes finding the tank, digging out the access port (pumping should be done through the manhole, not the smaller inspection port), pumping out the tank (leaving nothing inside), checking for leaks, and then backfilling and re-grading the site.
• Never enter a septic tank; they are extremely unsanitary and may contain deadly gases. Many states require septic tanks to be pumped out only by trained and licensed professionals.

• Some companies charge a flat fee for locating the septic tank and digging down to the access port, while others charge for the actual hours worked. Depending on the time involved, you can save some money if you're willing to do the locating and digging yourself.
• Tip: While the tank is uncovered, draw a map of its location in relationship to the house or take photos; this can be valuable for future pumping or other septic service.

• Check with your local health department to see if they maintain a list of licensed septic cleaning companies.
• Ask about training and experience. Check that the company is properly bonded, insured and licensed in your state; and see if there are any complaints with the Better Business Bureau.
• Referrals to septic service retailers and providers are available through the National Onsite Wastewater Recycling Association.
