Abstract

An apparatus for controlling a flow of a liquid into a sewer drain comprising a catch basin having a catch basin drain coupled with the sewer drain. In addition, a housing element that is positioned within the catch basin, whereby the housing element is coupled with the catch basin drain in a first fluid-tight manner. The housing element having a porous surface positioned below a predetermined level. A column having a proximal end and a distal end, whereby the column is positioned within the housing element and the proximal end is coupled with the catch basin drain in a second fluid tight manner. The distal end is positioned above the predetermined level and an actuator mechanism is coupled with the column and configured to selectively open and close the column to the flow of the liquid that is entering the catch basin drain.

Claims

1. An apparatus for controlling a flow of a liquid into a sewer drain comprising:

a. a catch basin having a catch basin drain coupled with the sewer drain;

b. a housing element positioned within the catch basin, the housing element coupled with the catch basin drain in a first fluid-tight manner and having a porous surface positioned below a predetermined level;

c. a column having a proximal end and a distal end, the column positioned within the housing element, wherein the proximal end is coupled with the catch basin drain in a second fluid tight manner and the distal end is positioned above the predetermined level; and

d. an actuator mechanism coupled with the column and configured to selectively open and close the column to the flow of the liquid entering the catch basin drain.

2. The apparatus in claim 1 further comprising a membrane coupled with the housing element, wherein the liquid passes through the membrane before enteringthe conduit.

3. The apparatus in claim 2 wherein the membrane is made of a reticulated foam material.

4. The apparatus in claim 2 wherein the membrane is positioned around an outer surface of the housing element.

5. The apparatus in claim 2 wherein the membrane is positioned within the housing element.

6. The apparatus in claim 1 wherein the actuator mechanism further comprises:

a. a cap coupled to the distal end of the column, the cap having a first position and a second position, wherein the cap is biased to be in the first position; and

b. an actuator coupled with the cap, wherein the actuator induces the cap to move from the first position to the second position.

7. The apparatus in claim 1 further comprising at least one sensor for sensing a level of toxicity in the liquid entering the apparatus, wherein the sensor activates the actuator mechanism when the level of toxicity reaches a predetermined value.

8. The apparatus in claim 1 wherein the actuator mechanism is activated by a remote device.

9. An apparatus for controlling a flow of a liquid into a sewer drain comprising:

a. a housing element having an outer surface, the housing element including at least one aperture on the outer surface, wherein at least some of the liquid enters the housing element through the aperture;

b. a conduit positioned within the housing element, wherein the conduit is coupled with the sewer drain in a fluid tight manner; and

c. an actuator mechanism coupled with the conduit, the actuator mechanism further comprising;

i. an actuator; and

ii. a cap coupled to the actuator, the cap configured to operate between a first position and a second position, wherein the liquid enters the sewer drain when the cap is in the second position.

10. The apparatus in claim 9 further comprising a membrane coupled with the housing element, wherein the liquid passes through the membrane before entering the conduit.

11. The apparatus in claim 10 wherein the membrane is positioned around the outer surface of the housing element.

12. The apparatus in claim 10 wherein the membrane is positioned within the housing element.

13. The apparatus in claim 10 wherein the membrane is made of a reticulated foam material.

14. The apparatus in claim 9 further comprising at least one sensor for sensing a level of toxicity in the liquid entering the apparatus, wherein the sensor activates the actuator mechanism when the level of toxicity reaches a predetermined value.

15. An apparatus for controlling a flow of a liquid into a sewer drain comprising:

a. a housing element having a chamber and at least one aperture positioned at a predetermined height on an outer surface of the housing element for allowing the liquid to enter the chamber;

b. a conduit having an opening configured to permit the liquid entering the chamber, the conduit coupled with the sewer drain in a fluid tight manner, wherein the flow passes to the sewer drain through the conduit; and

c. an actuator mechanism coupled with the conduit, the actuator mechanism configured to selectively control the liquid from entering the sewer drain.

16. The apparatus in claim 15 wherein the conduit is positioned within the chamber and having the opening positioned above the predetermined height.

17. The apparatus in claim 15 further comprising at least one sensor for sensing a level of toxicity in the liquid entering the apparatus, wherein the sensor activates the actuator mechanism when the level of toxicity reaches a predetermined value.

18. The apparatus in claim 15 further comprising a membrane coupled with the apparatus.

19. The apparatus in claim 15 wherein the actuator mechanism further comprises:

a. a cap coupled to a distal end of the conduit, the cap having a first position and a second position, wherein the cap is biased to be in the first position; and

b. an actuator coupled with the cap, wherein the actuator induces the cap to move from the first position to the second position.

20. The apparatus in claim 15 wherein the actuator mechanism further comprises a butterfly valve.

21. An apparatus for controlling a flow of a hazardous material into a sewer drain comprising:

a. a housing element having a first end and a second end, the housing element positioned to have the second end coupled with the sewer drain in a first fluid-tight manner, the housing element having at least one aperture for allowing the flow to enter the housing element;

b. a conduit positioned within the housing element, the conduit coupled with the sewer drain in a second fluid tight manner, wherein the flow enters the sewer drain through the conduit;

c. an actuator mechanism coupled with the conduit, the actuator configured to selectively allow and prevent the flow from entering the sewer drain; and

d. a membrane coupled with the housing element, wherein the hazardous material flows through the membrane before entering the sewer drain.

22. The apparatus in claim 21 wherein the membrane is positioned around an outer surface of the housing element.

23. The apparatus in claim 21 wherein the membrane is positioned within the housing element.

24. The apparatus in claim 21 further comprising at least one sensor for sensing a level of toxicity in the hazardous material entering the apparatus, wherein the sensor activates the actuator mechanism when the level of toxicity reaches a predetermined value.

25. The apparatus in claim 21 wherein the membrane is made of a reticulated foam material.
