I was referred to AOS, and it's the best one I've ever had! Replaced my failed home sewage pump on the same day in record time. With competitive costs and great service, I'll never use anyone else. A true "customer service" business!
We have used these guys a few times over the years. This last experience was even better than the great service we’ve had in the past.I briefly explained my problem, they worked out a schedule to be here the next day.Amanda was great, but I have to give a huge thanks to Josh. He remembered us from a few years past, identified my issue quickly and gave me great advice to solve it quickly to avoid bigger issues later.I highly recommend them!!Thanks again.Chad BurnettNewberg

So grateful to Jim & John who came to the house. The lady on the phone listened, asked a few questions about the clean out pipe and yard. Drains had been working all day then did a load of laundry in the evening and suddenly everything is backing up. We made a few calls around immediately the next morning when it was obvious we couldn't clear it ourselves. American came to the house a few hours later, friendly, helpful, didn't just do the job but took the time to review out septic maintenance practices so they could get a good idea of how it may be flowing, or not, and why. Got the clog cleared and came in considerably less $ than I expected to pay. Definitely will call them again, just hopefully not too soon. Thank You!

If anyone ever needs septic system help these are the people to call. We had a recent septic emergency. A company we had used before pumped the tank. Within 3 days tank was full again. The "X" company we had used to pump tank told us drain field needed replaced, an 8K-16K expense.A friend suggested we call Dave at American On Site to get a second opinion. What a different story, he confirmed that our drain fields were fine and within a short time had men out that cleared the blockage to drain field and did a simple repair on septic tank. Total bill was extremely reasonable. I never do reviews, but for Dave I needed to take the time as he kept us from emptying our bank account for repairs not needed.

  • Slow Drains: Slow drains in sinks, tubs, or showers could indicate that your system is full and needs septic service in Wilsonville.
  • Unpleasant Odors: Foul smells from your drains or yard could indicate that your septic system is full or there is a blockage.
  • Backup: A backup in your toilet or drain indicates that your septic system is full and needs to be pumped. 
  • Lush Vegetation: If lush vegetation is abundant in your drain field or around the septic tank, it could signal that the system is overloaded and needs to be pumped.
  • Standing Water: If you notice standing water in your yard, it could signify that your septic system is not draining properly and needs to be pumped.
  • Keep “system cloggers” out – Trash like diapers, baby wipes, cigarettes, coffee grounds, fats, oils, grease, and feminine hygiene items are not meant to be flushed or poured into toilets. 
  • Be water smart – Keep your septic system from being overloaded by curbing excessive water use in your home. Consider energy-efficient appliances that use water, such as washing machines and dishwashers. Stagger the amount of water you use, as well. Showering, running the dishwasher, and doing laundry simultaneously is not good.
  • Don’t drive over your drainfield and septic tank – It’s illegal to drive over a drainfield or septic tank. Additionally, be mindful of plantings in your landscaping near your septic tank and system since they can cause problems and might require another septic tank pumping in Wilsonville.

Yes. Experts say septic pumping in Wilsonville should be done in 1 to 2 years, but several factors should be considered when deciding how often your septic tank needs to be serviced. You must consider the system’s age, the number of occupants in your home, the garbage disposal use, and the amount of laundry done in the home. Every system is different.

Septic systems typically last 20-30 years in the United States. Depending on the soil conditions and septic tank pumping in Wilsonville, the tanks can last as long as 50 years.

Using bacterial additives or septic tank treatments for septic systems is a matter of some debate in the industry, and there needs to be a clear consensus on their efficacy. Some experts believe adding bacteria to a septic system can help break down solids, improve effluent quality, and reduce odors.

However, others argue that septic systems are self-sustaining and naturally contain all the necessary bacteria and enzymes to break down waste. In some cases, adding bacteria or other additives during septic service in Wilsonville may even harm the system by upsetting the natural balance of bacteria and interfering with the treatment process.

You need to keep your septic system serviced and well-maintained for health and safety reasons, to protect the environment, and to save money in the long run. A malfunctioning septic system can spread harmful pathogens and bacteria that cause illnesses, contaminate the environment, and harm water sources, wildlife, and natural habitats. Regular maintenance, septic pumping in Wilsonville, and inspection of your septic system can prevent costly repairs and extend the life of your system, ensuring that it functions properly and efficiently for many years.
