There are mainly 3 weather events that can affect your system:

  1. Extreme Cold:  Cold winter weather can make it difficult for the bacteria in your septic tank to survive.   The bacteria found in your tank digests and breaks down the raw sewage.  When it is too cold the bacteria can’t do their job effectively and you will get more “undigested waste” finding it’s way to the bottom of your tank and causing a build-up of sludge.  If you have longer extended periods of extreme cold weather then you should consider having your sludge levels measured and possibly having your tank pumped more frequently.
  2. Heavy Rainfall:   Thankfully on the island, we don’t have to work too much about the “Extreme Cold”, but we definitely have heavy rainfall from time to time.  When this happens it can flood your drain field which will make it harder for the effluent coming from your tank to drain.   This can cause backups and flooding inside your home. If this happens your tank will require a pump-out immediately.   The best way to avoid this problem is to have your system maintained regularly,  (at least once a year).  This will help keep your field in good shape by removing blockages, equalizing flows,  and keeping the soils around your lateral lines from building up with bio-mat.  The better your soils can perk and drain water the less chance for flooding.
  3. Wind Storms:   This is a weather event that you would not think would affect things,  but we have had the phone ringing from this past year’s wind storms.  Tank lids have been smashed, control panels hit, field laterals have been damaged as large trees and limbs have fallen on fields.
