OK This Is What

When last we met, the creek project was finished, the concrete drain pipe was dry, water was bubbling up from the creek bed surface  and our basement sump pump was going off every 15 minutes.

UPDATE:  now it goes off every 5-10 minutes.

The prevailing thought at the time was that the gradient of the creek bed had been reversed and that is what was causing the sudden appearance of water in our basement, but further investigation prompted by my husband revealed that it’s not the gradient issue at all! It’s that the level of the water table has risen. Here’s why:

  • the creek bed has been raised to two feet above the level of our sump pump
  • the concrete pipe which formerly has always had some water coming from it -with a  huge leap in volume and speed during and after rainfall- has been dry as a bone so it’s probably broken and contributiong to the ground water collection.
  • the (newly raised) creek bed is has been filled with sand and clay which was then compacted by a big pounding machine so that there’s no way ground water can filter through it

Isn’t this depressing?

  1. I’ve thought about this, so if you think I’m crazy, then just ignore my comment.

    Dig a hole 4 feet into the bottom of the creek with a post hole digger, or small auger. Fill the hole with rock, which will keep it from caving in and allow the ground water to seep. Over time, it should lower the water table.

  2. I guess I’ll have to explain.

    From my experience with excavations, creek bottoms aren’t determined by accident. Water found the least restriction, so it eroded the soil; usually to a extremely hard, or sand substrate. With the the hard substrate, the erosion becomes very slow, so you end up with small rocks and gravel.

    With a sandy substrate, the layer of sand is like a slow river, with water migrating through the sand. The sand may erode somewhat, but the large deposit replenishes the sand, so the water doesn’t erode deeper into the ground.

    If there’s a heavy overburden on this sand, the water is not only trapped, it’s contained and can’t exert enough pressure upward to move the overburden. Remove, or punch a hole in this overburden, and the water will “spring” through the new outlet until the water pressure is reduced by lowering the height.(I’ve seen water push a one foot thick clay bottom upward until the water bearing sand burst through the clay and flooded the trench)

    So, if I’m correct, they placed enough of a clay bottom to trap the water, prevent the surrounding water from arriving at the previous location and effectively created an underground dam. Punching a hole allows the water to escape, even if it has to siphon, due to the surrounding fill that was just placed.

  3. You could always raise fish in your basement. Might make a tidy income if your girly parts get tired of pulling levers.

  4. So very sorry to see this–I’m willing to bet you have neighbors with the same “new” problems. I think if you all get together, contact a good lawyer and go after the powers that sponsered this project your property could be made whole–minus all the full-grown trees, I’m afraid. Aren’t they even going to plant something so you won’t have to look at all those yards across the creek?

  5. this makes me angry! I can’t even imagine how you must feel 😦
    I wish you the best of luck and truly hope it works out for you guys!
