depending on how nice a basement you have or want to have
it is probably best to just install a pit and pump
and pump it down the side of the hill
Now their are places that will cut the concrete all around your basement ,
and dig a perimiter drain all around the inside of your home, then install a black drain pipe and
pee gravel and
then pipe it into a sump pit.....
also they will place a plastic panel up all the walls to
force the water to go down into the pee gravel and ove rto the sump pit....
this will cost you probably around 6 ,000
at least in the mid west
