Septic Tank Replacement Portland Oregon & Surrounding Areas

Goodman Sanitation in Portland, OR & Surrounding Areas appreciates your property as much as you do. We understand that the prospect of replacing a septic tank is not pleasant and is a task best left to competent professionals who will handle the job quickly and with quality service.

Your septic systems is basically a large filter and, like any filter, it requires regular maintenance to keep it working effectively. When filters become clogged through neglect, they can being to fail. A septic systems failure results in costly and unsafe problems:

Septic wastewater may flow up into your yard
Septic wastewater may back up into your home
Replacement may be required for parts of the systems
The entire septic systems may need to be replaced


It has been said that the grass is always greener over the septic tank. That sounds amusing but, in fact, it is not a good sign if you have lush vegetation growth and wet spots over the drainfield. It could indicate a septic systems failure along with these other warning signs:

Septic tank or plumbing backups
Slow draining plumbing fixtures
Gurgling sounds evident in your plumbing systems
Odors in your yard and/or surfacing sewage


Today's septic tank materials are much more durable than those used in the past. Many older pipes such as terracotta and cast iron become brittle. Ground freezing and thawing along with tree roots can also take their toll on these pipes. Eventually they can become clogged, weak, and may eventually collapse, resulting in a septic systems failure.

When household flow rates exceed the septic tank's capacity to accommodate them or when an old tank is in an extreme state of disrepair, it becomes necessary to replace the septic tank. We will assess the proper size tank that needs to be installed and will replace your old one with a new tank that effectively suits your needs.
