Abstract

A method of and an apparatus for rejuvenating a wastewater treatment system of the type including a septic tank, an aerobic treatment unit or the like connected by a pipe to a plugged downstream soil absorption system includes a wastewater treatment unit which is interposed between the septic unit/aerobic treatment unit and the downstream soil absorption system. The wastewater treatment unit includes a single piece or a multiple piece solids settling and retention basin within which is suspendingly supported a wastewater treatment mechanism essentially of the type disclosed in U.S. Pat. No. 5,264,120. The wastewater treatment mechanism includes filters for filtering and settling solids from wastewater and flow equalization ports for effecting flow equalization thereby eliminating flow surges to the downstream plugged soil absorption system. By utilizing an extremely compact solids settling and retention basin and its attendant operative components, solids are prevented from passing beyond the wastewater treatment unit to the failed soil absorption system. In this fashion the wastewater treatment unit of the present invention can rejuvenate wastewater treatment systems which have failed, and if installed prior to such failure, can extend the life thereof substantially indefinitely. The latter and other advantages are achieved at relatively low cost, absent destruction of existing sod or lawn, moving fencing, trees, etc., and absent creating a hazard for individuals, particularly small children.

Claims

1. A compression clamp comprising a one-piece molded polymeric/copolymeric band of a substantially U-shaped configuration along at least one portion of the length thereof, said band having opposite first and second end portions, a minor terminal tongue projecting beyond said second end portion, said tongue having a plurality of spaced slots, the first end portion having an upstanding wall with a slot therein adapted to slidingly receive therein said tongue, a flexible tab disposed adjacent said slot, and said flexible tab having a projection directed for entry into selected one of said plurality of spaced slots upon said tongue being slid into and through said slot.

2. The compression clamp as defined in claim 1 wherein said flexible tab is defined by a wall projecting in a direction away from a terminal edge of said first end portion.

3. The compression clamp as defined in claim 1 wherein said flexible tab is defined by a wall projecting in a direction away from a terminal edge of said first end portion, and said flexible tab is defined by a substantially U-shaped slot opening in a direction toward said first end portion terminal edge.

4. The compression clamp as defined in claim 1 including means carried by said first end portion for sliding receipt in one of said plurality of slots.

5. The compression clamp as defined in claim 1 including means carried by said first end portion for sliding receipt in one of said plurality of slots, and said last-mentioned means is an upwardly projecting lacking tab.

6. The compression clamp as defined in claim 1 including means carried by said first end portion for sliding receipt in one of said plurality of slots, and said last-mentioned means is an upwardly projecting locking tab having an opening therein adapted to receive a locking mechanism.

7. The compression clamp as defined in claim 1 including a plurality of spaced means along said second end portion for receipt thereat of an end of a lever first passed through one of said plurality of slots for tightening the compression clamp about an associated body.

8. The compression clamp as defined in claim 2 including means carried by said first end portion for sliding receipt in one of said plurality of slots.

9. The compression clamp as defined in claim 2 including means carried by said first end portion for sliding receipt in one of said plurality of slots, and said last-mentioned means is an upwardly projecting locking tab.

10. The compression clamp as defined in claim 3 including means carried by said first end portion for sliding receipt in one of said plurality of slots.

11. The compression clamp as defined in claim 3 including means carried by said first arid portion for sliding receipt in one of said plurality of slots, and said last-mentioned means is an upwardly projecting locking tab.

12. The compression clamp as defined in claim 2 including a plurality of spaced means along said second end portion for receipt thereat of an end of a lever first passed through one of said plurality of slots for tightening the compression damp about an associated body.

13. The compression clamp as defined in claim 3 including a plurality of spaced means along said second end portion for receipt thereat of an end of a lever first passed through one of said plurality of slots for tightening the compression clamp about an associated body.
