What does NOT go down the drain

Increased water to the system is not a good thing. Clean water contains no food or nutrients for the “bugs” that make the system work and too much flow can also wash the good “bugs” out of the system. Sources of this water can be:

  • Draining pools and spas
  • Yard drains
  • Roof drains
  • Broken or missing clean out covers

These sources of flow to the sewer are not good and create extra time and expense in the operation of the system and reduce efficiency and effluent quality. Other considerations that affect how well your system works include:

Do Not Put

  • Grease down the drain  
  • Pharmaceuticals (expired/unused pills can be turned in at the Police Department)
  • Herbicides (bug and lawn care products)
  • Oil based paints and solvents
  • Chlorine from pools and spas
  • Any toxic substance
