Will My Septic System Still Work When My Power is Out.?

Yes. Your septic system will work without power but if your power fails it is important to be water wise. Pump septic systems do need electricity to move effluent (liquid sewage) from the septic tank into the drainfield.

How does my pump septic system work without power?

If you have a septic system with a pump, your system relies on electricity to pump the wastewater into the drainfield, so how does it still work without power? Simple. All the liquid sewage you flush into the septic, as well as the other water you use, is held in the pump tank until the power returns and the pump moves the effluent into the drainfield.

How Much Water Can You Use When the Power Is Out?

If you have a septic system, during a power outage you want to be smart about how much you flush, how much you shower and overall water use.  A typical pump tank will have 300 - 500 gallons of extra space available to be used for pump failures or power outages. With that being the case, it is important to judge how long you think the power will be out to determine how to conserve. When the pump tank is full, you will be backed-up until the power comes back.  The objective is not to fill the pump tank so that you can still flush the toilet without power.

How Long Will the Power Outage Last?

When determining how much to flush, shower and use water for dishes and laundry you first want to think about how long the power will be out.  For example, if it's a big storm and there are wide-spread power outages, then it will likely take longer to restore power. Superstorm Sandy of 2012 had many areas without power for three days or more. In a case like that, it's wise to limit showers, avoid doing laundry and be very strategic about your water use by following these tips:

  • Take short showers
  • Don't wash laundry
  • Don't let the water run while brushing your teeth
  • Keep your toilet flushes for solids
  • Don't let the water run when washing dishes
    • fill one sink with water to soak dirty dishes when necessary.
