We just finished building our house this spring and now I need to
tackle the job of installing drainage for gutters, sump pump and some
low lying areas. I have a retention pond at the rear corner of my
property so I will be draining into there. I also slope 14' from front
opposite corner to that rear corner so slope should not be an issue.
My question is, what kind of pipe is best? I have been thinking about
using the really good SDR26 pipe, green gasketed stuff for sewer lines
although it is really expensive and I need 429' of the stuff. What
other options are there? I don't want to use the black corrugated pipe
because I think it is crap.
Well, this is just my oppinion. I have a 1.5 acre lot and I got a
sizeable Kubota tractor. I don't want to risk collapsing it as I know
it collapses easy as well as I believe that it clogs easier than a
smooth wall pipe due to the corrugations. Either way, I think I will
be using some sort of smooth wall alternative which seems to be SDR26
or SDR35 pipe.
Corrugated HDPE can come with the interior smooth, however the corrugation
serves to slow runoff and increase percolation (when full perforated pipe is
used). If a filter sock is used you'll minimize the possibility of clogging
(they come pre-equipped with filter sock now, really convenient.)
Thanks. I think I have decided that I am going to go ahead and use
corrugated HDPE pipe however I am going to ensure that it is at least
12" underground. Now, the question, if I use this pipe with filter
sock, do I still need to bury it in gravel as well? Would I be better
served useing HDPE with no perforations for my longer runs? Like I
said, I have a retention pond at the rear corner of my lot and my lot
slopes 14' diagonally towards this corner so flow should not be a
problem. I intend to run it to there or would it be better to just
terminate each run under ground with perforated pipe and a french
