no, im not a tree hugger. however, my pool is about 35 feet uphill from our neighborhood pond. a pond that my boys and I enjoy as much as we do our pool, boating and fishing. the last thing i would want to do is anything that would harm the pond system. i dont backwash often and when i do, i try to keep water loss minimal as it can runoff down to the pond. i am most concerned with closing the pool when i will have to drain it down below inlet fittings. thats a lot of water.
i have already buried my backwash hose and located the end of it to a spot that will hold a bit of water before it starts flowing down towards the pond. i have actually toyed with the idea though of digging my hose up, digging the trench 18 - 24 inches deep, buying a couple pieces of schedule 40 laterline PVC, a few bags of rock, and plumbing my sandfilter drain into this makeshift lateral line that would allow all backwashed and drained water to absorb into the soil rather than run on top of ground. even though this would be a lot of water, when i drain at the end of season i would drain slowly over several days to give the soil time to absorb it. laterals, properly built, can usually handle a lot of water though.
is pool water that bad to where i need to worry about this?
has anyone ever tried to use a lateral line to backwash into?
