Moss on septic drainfield #369262

Asked October 11, 2016, 8:34 AM EDT

We live in a wooded area. Our drainfield is on a north facing side hill that gets a fair amount of sun. The past 2 yrs have been rather wet so we have moss growing in areas that do not get a lot of sun especially around the edges of the lawn. There is a fair amount of moss growing on the drainfield. Is that OK or does the moss impede the operation/function of the drainfield? Is moss an acceptable ground cover for a drainfield? Thanks. Mark Nelson

Expert Response

Moss is an acceptable cover for the drain field.   However is it acceptable ground cover for you?   If the area has had grass before and now moss is growing, will this process increase?  Is this acceptable cover  for your needs.   I am assuming there are not problems with runoff from other areas and the drain field is functioning as designed.  There is much information about managing moss in a yard.  If you prefer grass to moss I suggest you read the publications on moss control and choose a method that suits your needs
