This summer, I will be building a rather large deck off the back of my house. The deck will cover 2 septic tanks. The deck will end a few feet before the d-box and the leach lines won't be covered in any way. Has anyone built a deck over their septic tanks? What precautions did you take and what should I be aware of?
Accessing the pump out lids: I have 3 possible options that I thought of. 1) Figure removable access ports into the deck plans. 2) Don't worry about the access ports. The entire deck will be put together w/ screws. So, removing a few boards once every 3 years isn't a major issue. 3) Construct a remote pump out.
Ok, now #3 is something i made up and don't even know if it's possible. Here goes.... would it be possible to feed a permanent service line into the lid of the tank, run it along underneath the deck and have it exit the side where it is capped off and easily accessible by the pump out guys? Anybody ever see this or something similar done?
Next question.... Before I build this deck, should I change out the lines that run from the house to the tanks? They are only about 1-2 ft below the ground and stretch for maybe 6 ft before they meet the tanks. The house was built in 64 and the septic man told me he believed the lines were original clay pipes. He recommended I change them before adding a deck. I'm not against it in any way. I just wonder if they might be better off left alone?
