Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
91 words
For recharging an aquifer including water bearing sand, a system comprising means defining an entrance into said aquifer including a trench extending toward said aquifer, said trench being lined with a membrane composed of relatively water tight material, particulate means disposed within said trench and adapted to conduct water into said aquifer, said entrance being relatively confined at its lower end at the aquifer and having a broadened upper end upon which water can be placed, and curb means defining said broadened upper end and adapted to confine the water therebetween.
Claim 2
Dependent Claim
91 words
For recharging an aquifer including water bearing sand, a system comprising means defining an entrance into said aquifer including a trench extending toward said aquifer, said trench being lined with a membrane composed of relatively water tight material, particulate means disposed within said trench and adapted to conduct water into said aquifer, said entrance being relatively confined at its lower end at the aquifer and having a broadened upper end upon which water can be placed, and curb means defining said broadened upper end and adapted to confine the water therebetween.
Claim 3
Dependent Claim
41 words
The device of claim 1 in which said means defining said entrance includes a series of wells extending between said trench and said aquifer, and well liners in said wells adapted to confine said water and direct it into said aquifer.
Claim 4
Dependent Claim
34 words
The system of claim 2 in which said well liner includes screen means located near the bottom of said trench through which the water may run into said wells and thence into the aquifer.
Claim 5
Dependent Claim
32 words
The system of claim 1 in which each said curb means includes a horizontal foot part extending inward toward said trench and upon which a tractor or the like may be supported.
Claim 6
Dependent Claim
39 words
The system of claim 4 in which a filter bed lies above said particulate means and between said curbing feet, said water being adapted to filter through said filter bed into said particulate means and thence into said aquifer.
Claim 7
Dependent Claim
40 words
The system of claim 5 in which said particulate means includes coarse gravel extending into said trench and finer gravel lying above said coarse gravel and within said broadened upper end and said filter bed lies on said finer gravel.
