St. Onge has been pumping residential and commercial properties in New Hampshire since 1972. During a routine pumping we check out the tank for any problems such as, build-up, missing baffles, clogged filters, sagging or broken pipes. We take the time to be professional, clean and informative. We pride ourselves in the ability to leave your property looking as if we were never there.

helpful information

  • Maintain a regular septic cleaning schedule of at least every 2 to 3 years.
  • Do not allow vehicles on your leach field. The weight can cause pipes to break.
  • Conserve water. Too much water can overload your system and adversely affect its function.
  • Do not flush bulky waste, grease into your system. It can cause blockage in the lines and back up.
  • Do not discharge water softeners into the septic system.
