Water treatment systems and methods
Systems, apparatus and methods are described that can be used for cleaning wells using unfiltered fluids and fluids that contain solid matter. A spray head assembly mounted in a pumping station comprises a hydrodynamic mixing chamber configured to create turbulence in a fluid received from a pump. The pump draws a fluid from a well of the pumping station and provides a pressurized stream of the fluid to a pipe. A nozzle associated with an outlet of the mixing chamber, receives the mixed fluid from the hydrodynamic mixing chamber and the nozzle disperses the mixed fluid to the surface of a body of the fluid in the well.
1. A spray head assembly for mounting in a pumping station, comprising:

one or more deflectors, each deflector receiving the spray from a corresponding nozzle, wherein each deflector directs a fluid received from its associated outlet to a surface within the well,
wherein the mixing chamber causes solids in the fluid received from the pump to impact a wall of the mixing chamber, thereby reducing the size of solids in the body of fluid.
2. The spray head assembly of claim 1 , wherein the deflectors generate a rotational force causing the nozzle to rotate around an axis of the spray head assembly.

a spray head assembly that has a hydrodynamic mixing chamber configured to receive a portion of the stream from a tap on the pipe and to create turbulence in the portion of the stream, a nozzle associated with an outlet of the mixing chamber, the nozzle receiving a mixed fluid from the hydrodynamic mixing chamber and dispersing the mixed fluid to the surface of a body of the fluid in the well, and at least one deflector that receives the mixed fluid from the nozzle, wherein the deflector directs the mixed fluid to a surface within the well, wherein the mixed fluid is homogenized and oxygenated by the mixing chamber, and wherein the mixing chamber causes solids in the mixed fluid to impact a wall of the mixing chamber, thereby reducing the size of solids in the fluid in the well.
15. The lift station of claim 14 , wherein the nozzle rotates around an axis of the spray head assembly and provides a spray of the mixed fluid to a wall of the well.
16. The lift station of claim 15 , further comprising a manifold system that provides an additive to the mixing chamber, wherein the mixing chamber mixes the additive with the fluid received from the pump and wherein the additive comprises at least one of ozone, an organic compound, a detergent and an oxidizer.
17. A grinder station, comprising:
