How to Care for Your Septic System

  • Regularly Inspect/Maintain your Septic System (every 2-3 years)
  • Divert Rainwater from the Septic Drainfield
  • Don’t Overload the Septic Tank and Drainfield
  • Keep Trees Away from the Septic System
  • The Toilet Isn’t a Garbage Disposal
  • Use Garbage Disposals Wisely
  • Minimize Heavy Duty Cleaners
  • Do Not Pour Grease Down the Drain!

Don't Waste Your Money

When you use W.R. Grieger for your Septic Cleaning we wash down your tank with a hose & remove ALL debris. We inspect inlet and outlet baffles. We check the integrity of the tank.

We Will Remind You When Service Is Due

Maintenance every two years can prolong the life of your system. If your current pumper is not using a hose to wash down your tank … you are washing your money away. We don’t Pump & Run!

Customer Testimonials

“Thanks again to you and Bill for all your help with the septic replacement. You both were so helpful and kind, every step of the way! We appreciate it! Also, thanks to Bill for helping to install the mailbox and save my special one.”

KIM B.

The guys were personable, professional, and incredibly on top of things. They were so prepared, were patient through a long inspection, and thorough in their work and cleanup. They patiently explained and answered all questions completely and honestly”

I want to thank you for making the HUGE effort and difference in improving the library. I could use a lot of silly puns about the last couple of days. But, all really want to say is thank you! You saved the day.”
