FAQs About New Septic Installation in Portland
Why Would I Need a Septic System Replacement?
Most septic tanks installed before 1990 were steel tanks. This material can easily rust and become brittle under normal septic conditions. If you need a septic system replacement, contact us today! We can replace a rotting steel tank and components so your system continues to function properly and keep the environment healthy.
What Happens During Septic System Installation?
The team at Lil’ Stinky will evaluate your property and soil to help you choose the right system for your needs. After permits are secure and plans are complete, we’ll dig and set the tank, install the drain field, and perform final inspections to ensure everything is working properly. When inspections are done and signed off by County Inspectors, we’ll backfill and level the ground around your system.
How Long Do Septic Installations or Replacements Take?
After permitting is complete, the actual installation or replacement can generally take a couple of days, depending on soil conditions, weather, and the system complexity. Before work begins, we’ll share a timeline so you know what to expect.
Do I Need Permits for A Septic System Replacement?
Proper permits are required anytime you are replacing or installing a septic system. The team at Lil’ Stinky makes the process easy by handling all required paperwork and inspections.
Will My Yard Be Damaged During Septic Installation?
Excavation is required for installing or replacing a septic system; however, our skilled team plans in advance and works to minimize the disruption.
Can I Just Replace My Septic Tank?
Sometimes a tank replacement is sufficient; however, a full inspection of the system is required to know for sure. If there are failures noted in the drain field or other parts that are deteriorating with age, a full system replacement may be a more reliable and cost-effective option. Lil’ Stinky will provide an honest recommendation based on your inspection.
