Secure weather containment system—enviro tank

1. An environmental containment system for at least one approximately 25 to 500 gallon chemical tank and pump, the system comprising:

a primary tank and an associated pump connected to the primary tank for pumping chemicals out of the primary tank;

the primary tank of approximately 25 gallon to 500 gallon capacity, and structured for substantial nesting within, and sealingly mating with, a secondary tank, the sealing mating being against weather;

the primary tank having a portion exposed to weather when the primary tank and associated pump are both configured in operative containment and pumping position with the secondary tank; and

the secondary tank structured and sized to accommodate the pump connected to the primary tank when configured in operative containment and pumping position and to provide, in conjunction with the primary tank, at least 110% containment of primary tank capacity.

2. An environmental containment system for at least one approximately 25 to 500 gallon chemical tank and pump, the system comprising:

at least one primary tank of approximately 25 gallon to 500 gallon capacity, structured for substantial nesting within, and sealingly mating with, a secondary tank, the sealing mating being against weather;

the primary tank having an exposed portion;

the secondary tank structured and sized to accommodate at least one pump and to provide, in conjunction with the primary tank, at least 110% containment of primary tank capacity: and

wherein the primary tank contains a nipple with a gasket located along a lower a wall portion nested within the secondary tank, for connecting the primary tank to the pump.

3. The system of claims 1 or 2 that includes a secondary tank access lid structured for sealing mating, against weather, with portions of the primary and/or secondary tank system and wherein the exposed primary tank portion includes a primary tank lid portion exposed to the weather.

4. An environmental containment system for at least one approximately 25 to 500 gallon chemical tank and pump, the system comprising:

at least one primary tank of approximately 25 gallon to 500 gallon capacity, structured for substantial nesting within, and sealingly mating with a secondary tank, the scaling mating being against weather;

the primary tank having an exposed portion;

pump and to provide, in conjunction with the primary tank, at least 110% containment of primary tank capacity and wherein sealing mating structure includes use of a rain drip bevel and an interlocking rain groove.

5. The system of claim 3 including a plurality of latches for press fitting the access lid against primary and/or secondary tank portions.

6. The system of claims 1 or 2 wherein the secondary tank has at least one fitting above a 110% containment level for ingress/egress of a line.

7. The system of claim 6 wherein the at least one fitting provides system ingress/egress for at least one of a supply, power and exhaust line.

8. An environmental containment system for at least one approximately 25 to 500 gallon chemical tank and pump, the system comprising:

at least one primary tank of approximately 25 gallon to 500 gallon capacity, structured for substantial nesting within, and sealingly mating with, a secondary tank, the sealing mating being against weather;

the primary tank having an exposed portion; and

the secondary tank structured and sized to accommodate, and containing, at least one pump and to provide, in conjunction with the primary tank, at least 110% containment of primary tank capacity and including a ventilation unit located in structure of the secondary tank above a 110% containment level, venting to the environment.

9. The system of claim 8 wherein the ventilation unit includes a louvered screen.

10. The system of claims 1 or 2 including a primary tank fluid level indicator, visible externally of the system.

11. The system of claim 3 wherein the primary tank lid portion includes a vented cap, externally accessible

12. A method for environmentally containing at least one approximately 25 to 500 gallon primary tank and associated connected pump for pumping chemicals out of the tank, the method comprising:

nesting at least one said primary tank of approximately 25 gallon to 500 gallon capacity within a secondary tank;

sealingly mating a portion of the primary tank with the secondary tank, against weather penetration, such that a portion of the primary tank is exposed to weather during operation, including during pumping chemicals out of the primary tank;

locating the pump connected to the primary tank within the secondary tank, sealingly protected against weather; and

structuring the secondary tank of sufficient size to provide, in conjunction with the primary tank(s), at least 110% containment of primary tank capacity.

13. The method of claim 12 that includes providing fittings for ingress and egress of at least one supply line and at least one power line into the secondary container, the location of the fittings being above the level of containment of at least 110% of the primary tank(s) capacity.

14. The method of claim 12 that includes sealingly mating an access lid of the secondary tank against portions of the primary tank and/or portions of the secondary tank and wherein the exposed primary tank portion includes a lid portion.

15. The system of claims 1 or 2 including two primary tanks substantially nested within a secondary tank and two primary tank lids sealingly mating with secondary tank wall portions.

16. The system of claims 1 or 2 wherein the secondary tank is sized to accommodate two pumps.
