This elevation is primarily a response to the presence of groundwater. In order for the septic system to operate effectively, it must be positioned at least four feet above the groundwater level. This strategic positioning ensures that the leach field remains sufficiently distant from the groundwater, allowing the sand to filter the water before it is reintroduced into the ground.


This septic system was excavated below the groundwater to get to a good layer of sandy soil that lets the water flow freely through it. The choice of this specific type of soil is crucial, as it enables efficient filtration. If unsuitable soil is left beneath the system, it has the potential to impede water passage, leading to system failure.

When septic systems become overloaded with excessive water, they may experience issues such as backups or surfacing on the ground. Moreover, the introduction of toxins that poison the microbiology within the septic system can have detrimental effects on its treatment performance. It is crucial to manage water input carefully and avoid the introduction of harmful substances to maintain the proper functioning and longevity of the septic system.

Failing Septic Systems Can Be Hazardous to Your Health

Septic systems that have been properly maintained help prevent the spread of disease.


Failing systems can:

  • cause a serious health threat to your family and neighbors,
  • degrade the environment, especially lakes, streams and groundwater
  • reduce the value of your property
  • be very expensive to repair


Be alert to these warning signs of a failing system:

  • sewage surfacing over the drainfield (especially after storms),
  • sewage back-ups in the house
  • lush, green growth over the drainfield
  • slow draining toilets or drains
  • sewage odors

Considering the elevated water table in many homes in Wilbraham, Hampden, Ludlow, and Monson, coupled with the increased rainfall this year, it is strongly recommended to schedule a thorough assessment of your septic system. Regular assessments play a crucial role in identifying early signs of potential issues, ensuring that the system continues to function effectively even in the challenging conditions posed by a high water table. Taking proactive measures through assessments can help prevent problems and maintain the optimal performance of your septic system in the face of varying environmental factors.
