Preventive Maintenance

The more frequently you have your tank maintained, the longer your septic system should last. Think of it like getting the oil changed in your car. The more it's used, the more upkeep is required. Preventive maintenance is the best way to increase the longevity of your septic system.
Bergendal Septic Service LLC recommends:
Pump Every Two Years If You Have One or Two People in Your Household
Pump Every Year If You Have Four or More People in Your Household
More Use = Increased Frequency of Maintenance

What Not to Put In Your Septic System!

Remember: Everything that goes down the drain goes into the septic system.

A septic system is designed to work on digested waste. Anything you cannot digest will add to the solid buildup in the tank.
Garbage disposals add to the amount of sludge and scum in your septic system
and frequently cause the filter to clog!
Bergendal Septic Service LLC does not recommend the use of a garbage disposal with your septic system.

Septic-Tank Additives

“Yeasts, bacteria enzymes and chemicals are sold with the claim of helping septic systems work better. However, there is no scientific evidence that additives are effective. In fact, some cleaners allow the solids in an overloaded tank to be resuspended and clog the drainage lines. Additives are not an alternative to proper maintenance and do not eliminate the need for routine pumping of a septic tank. Commercial biological additives are not necessary for restarting decomposition after pumping because the sludge residue contains active microorganisms.”
