Septic Tank Treatment

18 Do’s and Don’ts of Septic for Septic Tank Owners


  • Spread laundry washing over the week, rather than doing many loads on a single day.
  • Use a chemical free septic tank enzyme treatment like BioWonder to prevent backups and keep your septic system running smoothly between pump outs.
  • Make a record of where the important parts of your system are located for future septic system maintenance – for example, field repairs or tank pump outs.
  • Have professional septic pumping done on a regular basis and keep detailed records of septic tank maintenance, service and pump outs.
  • Learn the location of your septic tank and drain field. Keep a sketch of it handy with your maintenance records for service visits.
  • Do use water-conserving devices where possible. Low flush toilets and shower heads are the most common available. Install low usage water fixtures. By installing water-conserving fixtures, the average family can reduce the amount of water entering the septic system by 20,000 gallons per year!
  • Divert other sources of water, like roof drains, house footing drains, and sump pumps, away from the septic system. Excessive water keeps the soil in the drain field from naturally cleansing the wastewater.
  • Cover the drain field with a grass cover to prevent erosion and remove excess water.
  • Call a professional whenever you experience problems with your system, or if there are any signs of system failure.


  • Flush material that will not easily decompose, such as hair, diapers, cigarette butts, matches, or feminine hygiene products.
  • Wash or flush medicines or hazardous chemicals like paint, paint thinner and bleach into the system. They kill the helpful septic bacteria needed to decompose wastes in the septic tank and drain field.
  • Drive over or park heavy objects on the septic tank or drainfield.
  • Flush flushable wipes. Many septic tank pumpers and city public works employees are finding they don’t break down and cause serious headaches.
  • Plant anything over or near the drain field except grass. Roots from nearby trees or shrubs may clog and damage drain lines.
  • Dig in your drain field, build anything over it or cover it with concrete.
  • Allow backwash from home water softeners or condensate from an air conditioner or heat pump to enter the septic system.
  • Enter your tank. Any work to the tank should be done from outside. Gases that can be generated in the tank and/or oxygen depletion can be fatal.
