Above ground water tank fill/drain system
A trench is dug under an above ground water storage tank either before erection of the walls or after the wall is erected. A (rectangular) sump is preferably made of ¼ inch steel. It serves as a conduit from an inner tank liner port to an outside tank fill or drain port. The system eliminates hoses hung over the top edge of the tank wall. A pump can fill the tank from the outer port. The tank can be drained using head pressure of the water and/or a pump.
1. A method to fill of filling and empty draining an above ground water tank, the method comprising the steps of:
forming a trench;
placing an underground a sump in the trench below said above ground water tank, said sump having an inside port located below said above ground water tank and an outside port located on said sump outside a tank wall of said above ground water tank;
erecting a said tank wall over the underground said sump; forming an between said inside port on a top of the underground sump, which is inside the said tank wall, and said outside port which is outside said tank wall;
placing a tank liner over the said inside port;
securing the said tank liner over the to said inside port;
forming an outside port on the top of the underground sump;
attaching a filler hose to the said outside port; and
filling and draining the said water tank via the said outside port.
2. The method of claim 1 further comprising:
the step of forming placing a bolt at a center of the said inside port with a bottom of the said bolt fastened to a bottom of the said sump, forming placing a screen over the said inside port, forming placing a top donut flange 24 over the said screen, forming placing a bottom gasket over the said top donut flange, placing the said tank liner over the said bottom gasket, placing a top an upper gasket over the said tank liner, forming an upper placing a top donut flange over the top donut flange and the top said upper gasket, forming placing a clamp across the upper said top donut flange, and tightening the upper said top donut flange against the top donut flange said upper gasket using a nut threaded on the said bolt.
3. The method of claim 2 further comprising:
the step of forming connecting an outer port arch over the said outside port, the outer port arch having a connecting flange for the filler hose which is used to fill and drain the water tank.
4. The method of claim 3 further comprising the step of forming a second underground sump identical to the underground sump, placing the second underground sump alongside the underground sump, forming fluid communication ports between the underground sump and the second underground sump, and filling and draining the water tank via two outer port arches using two filler hoses.
5. The method of claim 1 further comprising:
the step of forming connecting an outer port arch over the outside port, the outer port arch having a connecting flange for the filler hose which is used to fill and drain the water tank.
6. The method of claim 5 further comprising:
the step of forming a second connecting an additional outside port with an to an additional outer port arch, wherein a second connecting flange on the outer port arch is of a smaller diameter than the connecting flange, and attaching a second filler hose to the second connecting flange.
7. The method of claim 6 further comprising:
the step of extending a pipe from the second said additional outside port down to about one inch above a bottom of the said sump, and draining the said water tank via the second said additional outer port arch.
8. The method of claim 5 further comprising:
the step of extending a pipe from the said outside port down to about one inch above a bottom of the said sump, and draining the said water tank via the said outside port arch.
9. A method to fill for filling and empty draining an above ground water tank, the method comprising steps of:
foaming a trench under a wall of an existing above ground water tank;
placing an underground a sump in the trench under said above ground water tank, said sump having an inside port that is located under said above ground tank and an outside port that is located outside a tank wall of said above ground water tank;
forming an inside port on a top of the underground sump inside the tank wall;
placing a tank liner over the said inside port;
securing the said tank liner over the to said inside port;
forming an outside port on the top of the underground sump;
attaching a filler hose to the said outside port; and
filling and draining the said water tank via the said outside port.
10. The method of claim 9 further comprising:
the step of forming placing a bolt at a center of the inside part port with a bottom of the said bolt fastened to a bottom of the said sump, forming placing a screen over the said inside port, forming placing a top donut flange over the said screen, forming placing a gasket over the said top donut flange, placing the said tank liner over the said gasket, placing a top gasket over the said tank liner, forming placing an upper top donut flange over the said top donut flange and over the said top gasket, forming placing a clamp across the said upper top donut flange, and tightening the said upper top donut flange against the said top donut flange using a nut threaded on the said bolt.
11. The method of claim 10 further comprising:
the step of forming placing an outer port arch over the said outside port, the outer port arch having a connecting flange for the filler hose which is used to fill and drain the water tank.
12. The method of claim 11 further comprising the step of forming a second underground sump identical to the underground sump, placing the second underground sump alongside the underground sump, forming fluid communication ports between the underground sump and the second underground sump, and filling and draining the water tank via two outer port arches using two filler hoses.
13. The method of claim 9 further comprising:
the step of forming connecting an outer port arch over the to said outside port, the outer port arch having a connecting flange for the filler hose which is used to fill and drain the water tank.
14. The method of claim 13 further comprising:
the step of forming a second providing an additional outside port with an outer port arch, wherein a second connecting flange on the outer port arch is of a smaller diameter than the connecting flange, and attaching a second filler hose to the second connecting flange.
15. The method of claim 14 further comprising:
the step of extending a pipe from the second said additional outside port down to about one inch above a bottom of the said sump, and draining the said water tank via the second said outer port arch of said additional outside port.
16. The method of claim 13 further comprising:
the step of extending a pipe from the said outside port down to about one inch above a bottom of the said sump, and draining the said water tank via the said outside port arch.
17. A sump system for filling and draining an above ground water tank, the sump comprising;
a flat, rectangular cross section pipe having a length of about seven feet, a width of about one and half feet, a height of about one half foot sump placed under said above ground water tank;
an inside port on a top adjacent an inside end of the sump disposed on said sump under said above ground water tank;
said inside port having a mating collar for a flange connected to a tank liner;
an outside outer port on the top adjacent an outside end of the sump; arch coupled to said sump for filling and draining said above ground water tank, said outer port arch located outside of said above ground water tank.
an outside port arch attached over the outside port and having a mating flange for a filler hose; and
wherein the mating collar further comprises a central bolt and a nut tightening a clamp collar around the tank liner.
