## Abstract

A water reclamation system includes a drainage lane overlaying a downward graded area of land and configured to receive water run-off from the land. At least one collection ditch coupled to the at least one drainage lane is configured to receive water from the drainage lane. At least one collection pipe housed is within and extends outwardly from the at least one collection ditch. A first container is coupled to the at least one collection pipe and configured to receive water from the at least one collection pipe. Housed within the first container is at least one water purifying filter and a pump configured to evacuate at least a portion of water within the container to a destination. A second container is in communication with the first container and is configured to: subject water received from the first container to a purification process; and store the purified water.

## Claims

### Claim 1

A method of assembling a plumbing system for water reclamation around a landmass, comprising: providing:
a first drain line configured to receive water from at least one in-building, used water source of a first group of sources and piped to a first community shared water purification system graded for purifying the first group of sources and a first intended re-use;
a second drain line configured to receive water from at least one in-building, used water source of a second group of sources, the second group of sources being different from the first group of sources and wherein the second drain line does not communicate with the first drain line and is in communication with a destination point; and
a third drain line configured to receive water from an external source, the external source being rain water or snow melt exterior to a building wherein the third drain line is separate from the first and second drain line and is piped to a second community shared water purification system graded for rain water and snow melt; and
wherein the first, second, and third drain lines located and sized based on a reuse strategy computed by a community shared computing system comprising a hardware processor and a memory;
wherein the reuse strategy includes a purification strategy according to detected chemical and biological content and the reuse strategy is further based on topographical survey data of the landmass, area rainfall and snowfall data, one or more building sizes of the landmass, run-off speed and rate of flow at one or more locations of the landmass, and water accumulation volume and speed at one or more locations of the landmass;
wherein the first group comprises in-building sources other than a toilet or dump sink wherein the dump sink receives chemical, pharmaceutical, or other regulated industrial waste.

### Claim 2 (depends on 1)

The system for water reclamation of claim 1, the second group is further separated into subgroups.

### Claim 3 (depends on 1)

The system for water reclamation of claim 1, further comprising the destination point is a second purification system graded for a second re-use.

### Claim 4 (depends on 1)

The system of claim 1, further comprising at least a portion of the first intended re-use water is further communicated to a higher level water purification system, which communicates the treated water back into a building for a higher level in-building use.

### Claim 5 (depends on 1)

The system of claim 1, further comprising the purification system is upgraded to a desired quality and communicated to a separate, higher level use in-building household supply line.

### Claim 6 (depends on 1)

The system of claim 1, further comprising the first drain line is piped to a water purification system that purifies water collected from a roof.

### Claim 7 (depends on 1)

The system of claim 1, further comprising a first supply line for drinking, cooking, and food and personal washing which is separated from a second supply line for filling a toilet, doing laundry and household cleaning; and
the second supply line receives at least some water from the community shared water purification system.

### Claim 8 (depends on 1)

The system of claim 1, the first drain lines of multiple buildings in a community are connected together to a first community purification system, and the third drain lines of multiple buildings in a community are connected together to a third community purification system.

### Claim 9

A method of assembling a plumbing system for water reclamation of a landmass, comprising: providing:
a first drain line configured to receive water from at least one in-building, used water source of a first group of sources and piped to a first water purification system graded for a first intended re-use;
a second drain line, different from the first drain line, receiving water from at least one in-building, used water source of a second group of sources, the second group of sources being different from the first group of sources and piped to a second water purification system graded for a second intended re-use;
a third drain line receiving water from an external source, the external source being rain water and snow melt collected from surfaces surrounding a building, the third drain line is separate from the first and second drain line and is piped to the first water purification system;
a first supply line receiving water from the first water purification system wherein the received water is graded for drinking, cooking, food preparation and personal washing; and
a second supply line receiving water from the second water purification system wherein the received water is graded for filling a toilet reservoir, household cleaning, and clothes laundering;
wherein the first, second, and third drain lines are located and sized based on topographical survey data of the landmass, area rainfall and snowfall data, one or more building sizes of the landmass, run-off speed and rate of flow at one or more locations of the landmass, and water accumulation volume and speed at one or more locations of the landmass as determined by automation and accompanying databases for a community of buildings.

### Claim 10 (depends on 9)

The system of claim 9, the first group comprises in-building sources other than a toilet or dump sink that receives chemical, pharmaceutical, or other regulated industrial waste.

### Claim 11 (depends on 9)

The system of claim 9, the second group comprises in-building sources comprising a toilet and a dump sink that receives chemical or pharmaceutical waste.

### Claim 12 (depends on 11)

The system of claim 11, the second group is divided into subgroups, separating chemical and pharmaceutical waste from toilet waste.

### Claim 13 (depends on 12)

The system of claim 12, the chemical and pharmaceutical waste is conducted to a collection container for separate collection, and toilet waste is conducted to a public sewer system or a private septic tank.
