SEPTIC System FAQs

How long does a septic tank and septic leach field last?

   A septic system usually has a lifespan of 50 years.  This depends upon use, and frequency of septic tank pumping.  Concrete septic tanks have a shorter lifespan than the HDPE septic tanks.  However, improper back-filling can reduce the lifespan of an HDPE septic tank.

How do I know when I need to replace my septic tank?

   If you smell sewage around the septic tank, or if your drains are backing up, these could be signs your tank has been compromised.  Sometimes, this means a line could be plugged, so you would want to get your septic line to your tank scoped.

Can I park on my leach field?

   You can never drive onto, or park, a vehicle on a septic leach field.  The weight of the vehicle or heavy equipment can crush, crack, and dislodge the septic pipes that allow the leach field's proper operation.

Can I plant around my septic system?

    Trees and bushes often have deep root systems.  Boulder, Larimer, and Gilpin Counties ask that you do not plant Aspens and other trees and bushes within 15 feet of your septic leach field and septic pipes.  Roots can crush the pipes over time.  If your plants have shallow roots, they can be planted on top and near septic systems.  Wildflowers are fantastic to plant.  Do your research, and make sure you know how deep your septic system pipes are, before planting anything.

Why do I need my septic tank pumped?

     The effluent inside a septic tank coat the concrete of a septic system.  It also creates gases.  These can erode a septic tank over time.  Getting your septic tank pumped regularly will slow the erosion time of a septic tank.  According to Boulder County Septic Smart and septic pumpers, a septic tank needs to be pumped every 2-6 years depending upon use.
