a base assembly connected to the upper assembly, the base assembly comprising one or more diffusers connected to opposing end portions of the base assembly; and a fluid path fluidly connecting the upper assembly and base assembly, wherein the fluid path extends from an outlet of the submersible pump to the one or more diffusers, and wherein the one or more diffusers are configured to provide a fluid outlet from the fluid path to create movement of fluid within a fluid reservoir. ## Claims ### Claim 1 A fluid mixing system, comprising: a. an upper portion, comprising an upper piping assembly and a submersible pump housed within the upper piping assembly; b. a base portion connected to the upper portion, the base portion comprising a bottom piping assembly and one or more diffusers connected to opposing horizontal extending end portions of the bottom piping assembly, wherein the upper portion and the base portion form an inverted T configuration the upper portion being substantially vertical and the base portion being substantially horizontal; and wherein the upper portion and the base portion are configured for being installed within a fluid reservoir; and c. a fluid path fluidly connecting the upper piping assembly and bottom piping assembly, wherein the fluid path extends from an outlet of the submersible pump to the one or more diffusers, and wherein the one or more diffusers are configured to provide a fluid outlet from the fluid path to create movement of fluid within a fluid reservoir, and wherein the one or more diffusers are positioned at a certain fixed angle relative to the bottom piping assembly and/or a horizontal surface of a bottom of the fluid reservoir which the fluid mixing system is installed wherein each of the opposing end portions of the bottom piping assembly each comprises a T pipe assembly. ### Claim 2 (depends on 1) The fluid mixing system of claim 1 wherein the upper portion further comprising a well screen disposed atop the upper piping assembly and in fluid connection with the submersible pump. ### Claim 3 (depends on 1) The fluid mixing system of claim 1 wherein the upper portion is connected to approximately a mid-point of the base portion. ### Claim 4 (depends on 1) The fluid mixing system of claim 1 wherein the one or more diffusers are connected to one or more ends of the T pipe assembly. ### Claim 5 (depends on 1) The fluid mixings system of claim 1 wherein the fluid path comprises a first pipe section, a second pipe section, and a third pipe section, wherein the first pipe section is connected at its first end to the outlet of the submersible pump and at its second end to a T connector connecting the first pipe section with the second and third pipe sections wherein the first pipe section extends in a vertical direction within the upper piping assembly and the second and third pipe sections, positioned end to end, extend in a horizontal direction in opposing directions from one another within the bottom piping assembly, the first, second, and third pipe sections forming an inverted T configuration. ### Claim 6 (depends on 5) The fluid mixing system of claim 5 wherein the second pipe section and the third pipe section each comprise a first portion and a second portion, wherein a diameter of the first portion is greater than that of the second portion. ### Claim 7 (depends on 5) The fluid mixing system of claim 5 wherein each T pipe assembly comprises a T pipe section connected at about its mid-point, one to each of the second pipe section and to the third pipe section in a T configuration at each of the opposing end portions of the bottom piping assembly. ### Claim 8 (depends on 5) The fluid mixing system of claim 5 further comprising a pipe reducer disposed between the outlet of the submersible pump and the first pipe section. ### Claim 9 (depends on 7) The fluid mixing system of claim 7 wherein each T pipe section comprises a first end portion and a second end portion. ### Claim 10 (depends on 9) The fluid mixing system of claim 9 wherein one or more of the diffusers are connected to the first end portion and/or the second end portion of each T pipe section. ### Claim 11 (depends on 10) The fluid mixing system of claim 10 wherein a diameter of the one or more diffusers is less than the diameter of the first end portion and the second end portion of the T pipe section. ### Claim 12 (depends on 1) The fluid mixing system of claim 1 wherein the certain fixed angle is calculated based on one or more of reservoir tank geometry, reservoir tank size, size of the submersible pump, and desired fluid volume turnover. ### Claim 13 (depends on 2) The fluid mixing system of claim 2 wherein the length of the well screen is determined by a high and low set points defined for a reservoir within which the fluid mixing system is installed. ### Claim 14 (depends on 2) The fluid mixing system of claim 2 further comprising an inverted pipe reducer disposed between the well screen and the upper piping assembly. ### Claim 15 (depends on 1) The fluid mixing system of claim 1 further comprising a low fluid cutoff sensor configured to turn the submersible pump off when a fluid level of a reservoir within which the fluid mixing system is installed reaches a pre-determined low fluid set point. ### Claim 16 (depends on 1) The fluid mixing system of claim 1 wherein the upper portion further comprises a stability plate for stabilizing the submersible pump. ### Claim 17 (depends on 1) The fluid mixing system of claim 1 further comprising one or more of mounting clips and a brace configured for securing the fluid mixing system within a reservoir in which the fluid mixing system is installed. ### Claim 18 (depends on 5) The fluid mixing system of claim 5 further comprising one or more torque arrestors positioned within the base portion, wherein the one or more torque arrestor are positioned relative to the second pipe portion and/or the third pipe portion.
