Your drainfield is an important part of your septic system. Here are a few things you should do to maintain it:
• Plant only grass over and near your septic system. Deep rooted plants such as trees or shrubs may clog and damage the drainfield.
• Don’t drive or park vehicles on any part of your septic system. Doing so can compact the soil in your drainfield or damage the pipes, tank, or other septic system components.
• Keep roof drains, basement sump pump drains, and other rainwater or surface water drainage systems away from the drainfield and limit your water use. If the amount of wastewater entering the system is more than the system can handle, the wastewater may back up into the house, emit foul odors or surface above ground in the yard.
