​Sewage waste can leak from septic tanks into drains, land or waterways. Many rural property owners use septic tanks to collect, treat and dispose of wastewater.

​What to watch out for

  • Blockage or overflow of sewage waste.
  • Broken septic tank lid.
  • Murky or smelly puddles on your property.
  • Scum and sludge buildup on your septic tank.

Sewage waste is harmful to the environment and is a health risk. Wastewater comes from showers, baths, washing machines and toilets.

To prevent pollution from your septic tank, see Maintain your septic tank.
