I will try again on the photos.. -my excavator has built many ponds/lakes, and assures me that this land (Avonburgh-clay) is lousy for building houses, but ideal for ponds,. -as did the Soil and Water conservation guys.. sodium bentonite is super-swelling and great for patching holes as I understand it, but not needed in this part of OH. That's why I decided to skip the liner. My "household sump" pump is feeding this first pool with crystal clear water, (that has percolated and filtered through more gravel that you can imagine under the foundation). Yesterday, they buried all of the downspouts to feed the same. Now I'm scared cause the downspout seems to enter below the final water line.. these are only 6 inches under ground or so.. -so what about freezing??? Azreno- I used 2 heavy duty sump pumps last time, and swore them off,. -this one will be dry,. -they performed OK, but since they were always submerged, they were yuchy.
