Why does a septic tank need to be pumped? Doesn't the bacterial action take care of the waste? In Alaska, tanks need to be pumped more often than in warmer climates since they are generally buried deeper. Since bacterial action works best in above 60 degree temperatures, and the temperature here averages about 47 degrees, solids accumulate faster and decrease the ability of the system to move the water into the leachfield at an acceptable rate. Additionally, we are using chemicals and chlorine in greater amounts than even 20 years ago which destroys the natural bacterial action in the tank. Periodic and proper pumping will remove this accumulation allowing the septic to perform effectively. How does a septic system work? Septic systems typically have two major components: a septic tank and subsurface disposal field (also known as a leachfield or drainfield). The tank is a watertight receptacle designed to receive domestic wastes. The lighter solids called scum (mainly grease) floats to the top. The heavy solids settle to the bottom where bacterial action partially converts them to a digested sludge. The liquid portion in the middle called effluent or "gray water" flows out of the tank through perforated pipes to the leachfield which is composed of sewer rock. Here, remaining solids further decompose and the liquid is absorbed into the soil, evaporates or is taken up by plants. View diagram here. Proper maintenance through regular pumping will remove excess solids and sludge, thereby extending the life of the average septic system by many years.

You wouldn't drive your new car 10,000 miles without checking the oil. The same principle applies to the septic system. Unfortunately, the first septic "emergency" usually marks the begining of the end. All too often we see non-believers become believers when their septic system backs up or they fail a perc test and have to replace it. Once a system starts to back up, it is generally the result of an accumulation of solids in your tank. Grease and non-biodegradables such as tissue, cigarette butts, feminine products, etc. flow into the leachfield and slowly clog the sewer rock and the walls of the leach ditch. Eventually, the water has no place to go and backs up into your house or business. By using water sparingly, eliminating chlorine products, and pumping regularly, your septic system should give you years of troublefree service. How often should we have our septic pumped? A lot depends on the size of the tank, the number of people in the household, the type of system, the usage, and the installation. In general, the more people using the system and the smaller the tank, the more often it should be pumped. For example, a 4-person household with a 1000 gallon tank should have their system serviced every two years. Households with five or more on a 1000-gallon tank should pump yearly. Rentals should be serviced yearly as many tenants believe they are on a city sewer and often don't know how to properly maintain a septic. Businesses which have a high volume of walk-in traffic such as restaurants and stores should also pump yearly at least. And if you have family planning to visit for any extended period of time, pump before they come as more people in the house puts additional stress on the septic system. Sewage back-ups with a house full of company are no fun! How long should it take to pump the tank? On the average, it should take a septic pumper between 20 and 35 minutes to clean a 1000 or 1250 septic tank which includes 1 or 2 backwashes, if needed. It may take longer if a tank has not been pumped for a while and there is an accumulation os solids and grease in the tank. Oftentimes rocks, diapers, baby wipes (which do not belong in the tank) will plug the hoses which results in extra time spent to service the septic. Also known as a backflush, this is where the pumper literally goes back to his truck and reverses the pump to shoot liquid back down into the tank. This is done to break up the accumulation of solids at the bottom of a tank thereby allowing the pumper to clean the tank. However, when a tank has been neglected and there is a large build up of hard solids at the bottom of the tank, the pumper may have to do more backwashes. Sometimes that is not even enough to break up the solids. A conscientious pumper will literally beat these hard solids with the septic hose to bust up the remaining hard solids to leave a clean tank. Additional time spent cleaning the tank due to accumulation of solids and grease will generally result in increased costs to the home or business owner. Periodic pumping helps keep those costs down and extends the life of the septic system. What are some tips for homeowners, business owners, and tenants? Septic systems cost thousands of dollars to replace. Annual septic maintenance averages less than $100 per year for the typical single family home.

How do I know I got a good septic service? We recommend that the homeowner be present when the pumper comes. You can see how long the job takes, whether backwashes are needed and ask questions regarding the condition of the septic. If you cannot be present, we suggest that you take a strong flashlight and look down into the incoming standpipes of your tank (the 1st pipe on the septic tank). First you want to be sure that it was your septic that was pumped. (It has been known to happen that the wrong tank has been pumped out what with missing street signs, lack of house numbers and new drivers on a route). If pumped properly, you should not see any solids at all. "Mountains of solids" are an indication you did not get a clean tank. A properly cleaned tank will extend the lift of your septic system for years. When is the best time of year to pump? We can pump a septic any time of year. Spring and summer are better as the ground is a bit warmer thereby allowing the bacterial action in a septic tank to start up faster. Many people like to wait until fall to schedule a service call as part of their pre-winter maintenance. However, if standpipes are cut low or flush with the ground, remember to mark them in case of a winter back up. I don't know how big my tank is can you tell me? In general, the following applies:
When garbage disposals are installed, an additional 250 gallons is recommended. Should I be putting enzymes in my septic? Septic tanks are designed to allow bacteria and enzymes to biodegrade organic waste. However, natural bacterium do not work well on protein, fiber or grease. Furthermore, modern chemistry has provided us with advanced cleaning products made of complex molecules which kill the bacteria normally found in a tank. And with colder ground temperatures found in Alaska, the natural bacteria need all the help they can get. ALPINE is the Valley distributor of Bio-Clean which is formulated to break down ALL types of biodegradable waste. It contains a higher quality, unique combination of ingredienents not found in other products. Monthly maintenance treatmens cost significantly less than inconvenient back ups and replacing leachfields. TIP: Beware of telemarketers who claim their products will eliminate pumping.
