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?
