Abstract

Processes and systems for treatment of wastewater are provided. Some of these systems and processes flow wastewater from an upright infiltrative surface into sand or other soil between opposing infiltrative surfaces and provide for aerobic treatment of the wastewater in the sand or other soil between the opposing infiltrative surfaces. Some of these systems and processes may employ spacing connectors positioned and configured to connect neighboring infiltrative channels.

Claims

1. A wastewater treatment system comprising:

a first, second, and third, infiltrative channel,

each of the three infiltrative channels spaced apart from each other,

each of the three infiltrative channels wrapped in filter fabric and having at least two upright infiltrative surfaces,

each of the three infiltrative channels having a height, a width, and a length wherein the height to width aspect ratio of each of the infiltrative channel is 3 or 96 or is between 3 and 96,

each of the three infiltrative channels have sections of one foot or more along their length without an upright interconnecting infiltrative surface interconnecting them to a neighboring infiltrative channel;

a first pair of spacing connectors connecting the first and second infiltrative channel, each connector of the first pair of spacing connectors connected to the first infiltrative channel and connected to the second infiltrative channel and configured to provide a spacing between the first infiltrative channel and the second infiltrative channel, neither connector of the first pair of spacing connectors comprising a pipe;

a second pair of spacing connectors connecting the second and third infiltrative channel, each connector of the second pair of spacing connectors connected to the second infiltrative channel and connected to the third infiltrative channel and configured to provide a spacing between the second infiltrative channel and the third infiltrative channel; and

a wastewater channel positioned to dispense wastewater to each of the three infiltrative channels, wherein the wastewater channel traverses no more than a portion of a lower boundary of each of the three infiltrative channels,

wherein at least a portion of an upper boundary of each of the three infiltrative channels is not directly underlying any section of the wastewater channel.

2. The wastewater treatment system of claim 1 wherein each of the infiltrative channels are configured for shipping to a job site.

3. The wastewater treatment system of claim 1 wherein at least one of the spacing connectors is linear.

4. The wastewater treatment system of claim 1 wherein each connector of the first and second pairs of connectors is anchored to an infiltrative channel.

5. The wastewater treatment system of claim 1 wherein each connector of the first pair of spacing connectors is located and configured to maintain a relative position between the infiltrative channels that each connector is connected to.

6. The wastewater treatment system of claim 1 wherein each of the infiltrative channels extend at least one foot beyond a surface of the wastewater channel.

7. The wastewater treatment system of claim 1 wherein at least one spacing connector in a pair is connected to a middle portion of one of the infiltrative channels.

8. The wastewater treatment system of claim 1 wherein a bottom leaching interface spans each of the at least two upright infiltrative surfaces of each of the three infiltrative channels and each bottom is positioned on a shared and level plane of reference.

9. The wastewater treatment system of claim 1 further comprising:

a first treatment channel, the first treatment channel positioned between the first and second infiltrative channels; and

a second treatment channel, the second treatment channel positioned between the second and third infiltrative channels,

wherein at least a portion of the upper boundary of each of the three infiltrative channels and an upper boundary of each of the two treatment channels is not directly underlying any section of the wastewater channel above the particular channel.

10. A wastewater treatment system comprising:

a first, second, and third, infiltrative channel,

each of the three infiltrative channels spaced apart from each other,

each of the three infiltrative channels having at least two upright infiltrative surfaces,

each of the three infiltrative channels having a height, a width, and a length wherein the height to width aspect ratio of each of the infiltrative channel is 3 or 96 or is between 3 and 96,

each of the three infiltrative channels have sections of one foot or more along their length without an upright interconnecting infiltrative surface interconnecting them to a neighboring infiltrative channel;

a first spacing connector connecting the first and second infiltrative channel, the first spacing connector connected to the first infiltrative channel and connected to the second infiltrative channel and configured to provide a spacing between the first infiltrative channel and the second infiltrative channel;

a second spacing connector connecting the second and third infiltrative channel, the second spacing connector connected to the second infiltrative channel and connected to the third infiltrative channel and configured to provide a spacing between the second infiltrative channel and the third infiltrative channel; and

a wastewater channel positioned to dispense wastewater to each of the three infiltrative channels, wherein the wastewater channel traverses no more than a portion of an upper boundary or a lower boundary of each of the three infiltrative channels,

wherein the first spacing connector and the second spacing connector do not comprise a pipe;

wherein at least a portion of the upper boundary of each of the three infiltrative channels is not directly underlying any section of the wastewater channel.

11. The wastewater treatment system of claim 10 wherein the infiltrative channels with connectors are configured for shipping to a job site.

12. The wastewater treatment system of claim 10 wherein the spacing connectors are linear.

13. The wastewater treatment system of claim 10 wherein the spacing connectors are collapsible.

14. The wastewater treatment system of claim 10 wherein the spacing connectors are anchored to at least two infiltrative channels.

15. The wastewater treatment system of claim 10 wherein the spacing connectors are located and configured to maintain a spacing between infiltrative channels that the connectors are connected to.

16. The wastewater treatment system of claim 10 wherein the infiltrative channels each extend at least one foot beyond an external surface of the wastewater channel.

17. The wastewater treatment system of claim 10 wherein at least one spacing connector is connected to a middle portion of one of the infiltrative channels.

18. The wastewater treatment system of claim 10 wherein each of the three infiltrative channels has a lower infiltrative surface where each of the three lower infiltrative surfaces is at the same invert elevation.

19. A wastewater treatment system comprising:

a first, second, and third, infiltrative channel,

each of the three infiltrative channels spaced apart from each other,

each of the three infiltrative channels wrapped in filter fabric and having at least two upright infiltrative surfaces,

each of the three infiltrative channels having a height, a width, and a length wherein the height to width aspect ratio of each of the infiltrative channel is 3 or 96 or is between 3 and 96,
