Are there any reasons besides looks, to mow the grass growing on a mound
septic system? 2.5 acres and it's all grass and I would just like to let
some of it grow wild, maybe throw out a few thousand wildflower seeds and
cut in some walking paths and let a lot of the rest of the grass just grow,
including what's on the mound. Any negatives to not cutting the grass on
One would also think that grass growing two feet tall will take
up more moisture from the ground than grass that is mowed
to 3". But I think all that is a nit. The path of the septic leach
field should be down, not going up. So, I'd say letting the
grass grow doesn't make any difference to the septic
If it's traditional field, I agree. If it's one of the newer advanced treatment
fields, I disagree. They lay the spider pipe in those systems fairly close to
the top of the mound. Ours was quite damp until the grass grew in over the first
summer. And as one of the reasons we chose this location was specifically to get
away from ground maintenance. There's no way I'm going to do any mowing!
Yes. There are basically two kinds of fields, seepage, and evaporation
or a combination of the two. The evaporation fields are larger or with
more surface area. Around here, perc test may determine how many
bedrooms you are allowed and now alternate fields are also required.
The county would like to push everyone into being hooked up to the sewer
OP says he has 2.5 acres and I guess he could pick any part to grow
however he wants. My neighbors yard grows completely wild and I've seen
his septic up. OK now but was a problem when kids and in-laws lived
there. Neighbor across street got by with a cesspool as there was just
him and his wife but when a family with kids moved in they elected to
tap into the sewer line.
Yes, if sewer lines are installed that could service your house, you may
be charged, even if you elect not to hook up.
I live in a rural area, and there are no sewer lines within miles of me.
As I remember (in 1984), the local law was 100' per bedroom. I only have
3 bedrooms, but the GC put in 400' of fields.
Here, it costs around $400 to empty the septic tank. I also have a dry
well for gray water (sinks, clothes and dish washers, and showers) which
costs about the same.
I also run off a 325' deep well, so I take the water out of the ground
in one place and return it to the ground in another place. I only pay
for the electricity for the pump. Fuel Oil and Propane are delivered by
trucks. The only company utilities I have come in from utility poles,
like electricity, telephone and cable TV/Internet, the last only
available after 1984 when I had the house built.
long term it might be a good idea to cut the grass at least once a
otherwise opportunistic trees may begin growing and their roots cause
drainage troubles long term./
no doubt this question should be answered by whoever services pumps
the OPs septic tank
As someone else suggested you should cut the grass occasionally. You
don't know how deep the root systems of wild plants will go. No doubt
there will be some that will get into the field and clog the thing
up. I keep the grass cut at least 30 feet back from my septic field.
I let the area beyond that grow wild as you want. The amount and
variety of growth is quite surprising and it changes over the years. I
have no idea whats growing out there for the most part but the Aspens
are moving out there through their root systems. They will eventually
take over the wild area. I plan to keep them back at least 50 feet
from the field, more if I ever see any evidence of them coming up
close to the septic field.
