Abstract
Abstract A compartmentalized waste disposal installation includes multiple disposal vaults, each positioned above a normal high water table level of the region. The vaults are disposed in parallel relationship and are stacked in two or more tiers to provide a compact permanent waste disposal facility. Each individual waste disposal vault provides water-impermeable encapsulation for the waste disposal materials and each individual waste disposal vault is positioned within a basin which has a water-impervious lining and a collection system for recovering leakage or leachate which may develop from each individual waste disposal vault.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
203 words
A permanent waste disposal installation comprising a group of multiple disposal vaults positioned above the normal high water table level of a region; at least two parallel, spaced-apart base vaults, each having a basin with a lengthwise slope from a high end toward a low end and having a channel shape from side to side, with the sides of the basins of all of the parallel base vaults being substantially parallel; an intermediate vault positioned between adjacent base vaults and having a basin with a lengthwise slope from the same high end toward the same low end and having a channel shape from side to side; each of said vaults having a water-impermeable encapsulation and being positioned above a distinct water-impervious barrier, a collection conduit beneath each said encapsulation and above the said distinct water-impervious barrier, said conduit extending beyond the said lower end of its respective basin; the said collection conduit for the said intermediate vault being aligned between the adjacent sides of the said adjacent base vaults; said group of multiple disposal vaults being covered with inert covering materials which are graded to correspond to the contour of the region; means for accumulating leakage and leachate from each said collection conduit.

A permanent waste disposal installation comprising a group of multiple disposal vaults positioned above the normal high water table level of a region; at least two parallel, spaced-apart base vaults, each having a basin with a lengthwise slope from a high end toward a low end and having a channel shape from side to side, with the sides of the basins of all of the parallel base vaults being substantially parallel; an intermediate vault positioned between adjacent base vaults and having a basin with a lengthwise slope from the same high end toward the same low end and having a channel shape from side to side; each of said vaults having a water-impermeable encapsulation and being positioned above a distinct water-impervious barrier, a collection conduit beneath each said encapsulation and above the said distinct water-impervious barrier, said conduit extending beyond the said lower end of its respective basin; the said collection conduit for the said intermediate vault being aligned between the adjacent sides of the said adjacent base vaults; said group of multiple disposal vaults being covered with inert covering materials which are graded to correspond to the contour of the region; means for accumulating leakage and leachate from each said collection conduit.
Claim 3
Dependent Claim
31 words
A permanent waste disposal installation including two separate waste disposal installations according to claim 1 and wherein the said means for accumulating leakage and leachate serves both separate waste disposal installations.
Claim 4
Dependent Claim
43 words
A permanent waste disposal installation according to claim 1 wherein said two parallel, spaced-apart base vaults are covered with a water impermeable layer which defines a valley between the said two vaults; and said valley defines the said basin of said intermediate vault.
Claim 5
Dependent Claim
36 words
A permanent waste disposal installation according to claim 1 wherein a drainage ditch is provided around at least a portion of the perimeter of said base vaults to divert surface water around said waste disposal installation.
Claim 6
Dependent Claim
22 words
A waste disposal installation according to claim 1 wherein the said water-impervious barrier is a preformed film of water impervious plastic substances.
Claim 7
Dependent Claim
21 words
A waste disposal installation according to claim 1 wherein said water impervious barrier is a sprayed on coating of asphaltic material.
Claim 8
Dependent Claim
23 words
A waste disposal installation according to claim 1 wherein acid water-impervious barrier is a layer of cementitious material at least six inches thick.
Claim 9
Dependent Claim
21 words
A waste disposal installation according to claim 1 wherein said cementitious material is a mixture of portland cement and inert fillers.
