Septic Tank Cleaning

For decades, Burlington-Delfino Septic Service has offered fast and reliable septic tank cleaning in Connecticut. The septic system is an onsite sewage treatment and disposal system buried in the ground. A septic system consists of a septic tank and a soil absorption area. On average, we recommend a septic tank cleaning in Connecticut every two to three years. The frequency depends on the home’s occupancy and the level of usage. If a garbage disposal is utilized in your home, than your septic tank should be cleaned more frequently. Cleaning your septic tank regularly will not only prevent inconvenient backups into the home, but prolong the longevity of the septic system. For your convenience, we will send you a reminder card when it's time to have your tank cleaned.

Septic System Maintenance Tips:

  • Clean your septic tank regularly based on the recommended frequency.
  • Have the baffles inspected at time of your septic cleaning.
  • Repair any dripping or leaking plumbing fixtures within the home to prevent flooding the septic system.
  • Divert roof drains and any surface water drainage away from septic system.
  • Do not allow vehicles or heavy equipment to drive over or park on your septic system.
  • Do not allow backwash from any water treatment systems to enter the septic system.
