The invention claimed is: 1. A method of pumping an oilfield fluid from a well surface to a wellbore comprising: providing a clean stream comprising water sourced from water tanks, wherein the clean stream contains primarily water; operating one or more clean pumps to pump the clean stream from the well surface to the wellbore; providing a dirty stream comprising a solid material disposed in a fluid carrier comprising the water sourced from water tanks, wherein the fluid carrier comprises a gelling agent; operating one or more dirty pumps to pump the dirty stream from the well surface to the wellbore; and combining, at the well surface, the clean stream and the dirty stream in a common manifold to form the oilfield fluid, and pumping the oilfield fluid to the wellbore. 2. The method of claim 1, wherein each of the one or more clean pumps is a first type of pump and each of the one or more dirty pumps is a second type of pump, and wherein the first type of pump is a same type of pump as the second type of pump. 3. The method of claim 2, wherein the first type of pump and the second type of pump are each plunger pumps. 4. The method of claim 1, wherein each of the one or more clean pumps is a first type of pump and each of the one or more dirty pumps is a second type of pump, and wherein the first type of pump is a different type of pump as the second type of pump. 5. The method of claim 4, wherein the first type of pump is a multistage centrifugal pump and the second type of pump is a plunger pump. 6. The method of claim 4, wherein the first type of pump is a progressing cavity pump and the second type of pump is a plunger pump. 7. The method of claim 1, wherein each of the one or more clean pumps is a multistage centrifugal pump. 8. The method of claim 1, wherein each of the one or more clean pumps is a progressing cavity pump. 9. The method of claim 1, wherein each of the one or more clean pumps is a plunger pump. 10. The method of claim 1, wherein the one or more clean pumps comprise any of one or more multistage centrifugal pumps, one or more progressing cavity pumps and one or more plunger pumps. 11. The method of claim 1, wherein each of the one or more dirty pumps is a progressing cavity pump. 12. The method of claim 1, wherein each of the one or more dirty pumps is a plunger pump. 13. The method of claim 1, wherein the one or more dirty pumps comprise any of one or more multistage centrifugal pumps, one or more progressing cavity pumps and one or more plunger pumps. 14. The method of claim 1, wherein each of the one or more clean pumps comprises a prime mover for supplying power, and wherein the prime mover is chosen from the group consisting of a diesel engine, a gas turbine, a steam turbine, an AC electric motor, and a DC electric motor. 15. The method of claim 1, wherein the one or more clean pumps are disposed remotely from the wellbore. 16. The method of claim 1, wherein the solid material is a proppant and wherein the oilfield fluid is a fracturing fluid. 17. The method of claim 1, wherein the solid material is one of a particle, a fiber and a material having a manufactured shape. 18. The method of claim 1, wherein the dirty stream further comprises one of an additive to change the characteristics of the oilfield fluid and a production chemical. 19. The method of claim 1, wherein the manifold is disposed upstream of the wellbore. 20. A method of pumping an oilfield fluid from a well surface to a plurality of wellbores, wherein the plurality of wellbores comprises at least a first wellbore and a second wellbore, the method comprising: providing a clean stream; operating one or more clean pumps to pump the clean stream from the well surface to both the first wellbore and the second wellbore; providing a first dirty stream comprising a first solid material disposed in a first fluid carrier; and operating one or more first dirty pumps to pump the first dirty stream from the well surface to the first wellbore, wherein the clean stream and the first dirty stream together form said oilfield fluid; providing a second dirty stream comprising a second solid material disposed in a second fluid carrier; and operating one or more second dirty pumps to pump the second dirty stream from the well surface to the second wellbore, wherein the clean stream and the second dirty stream together form said oilfield fluid. 21. The method of claim 20, wherein the one or more clean pumps are remotely located from the first wellbore. 22. The method of claim 20, wherein the one or more clean pumps are remotely located from both the first wellbore and the second wellbore. 23. The method of claim 20, wherein the first solid material and the second solid material is a proppant and wherein the oilfield fluid is a fracturing fluid. 24. A method of pumping an oilfield fluid from a well surface to a wellbore comprising: providing a clean stream comprising water sourced from water tanks, wherein the clean stream contains primarily water; operating one or more clean pumps to pump the clean stream from the well surface to the wellbore; providing a dirty stream comprising a corrosive material and the water sourced from water tanks, wherein the fluid carrier comprises a gelling agent; operating one or more dirty pumps to pump the dirty stream from the well surface to the wellbore; and combining, at the well surface, the clean stream and the dirty stream in a common manifold to form the oilfield fluid. 25. The pump system of claim 24, wherein each of the one or more clean pumps comprises any of one or more multistage centrifugal pumps, one or more progressing cavity pumps and one or more plunger pumps; and wherein each of the one or more dirty pumps comprises any of one or more multistage centrifugal pumps, one or more progressing cavity pumps and one or more plunger pumps. 26. The method of claim 24, wherein the manifold is disposed upstream of the wellbore. 27. The method of claim 24, wherein each of the one or more clean pumps is a plunger pump and each of the one or more dirty pumps is plunger pump. 28. The method of claim 24, wherein each of the one or more clean pumps is a multistage centrifugal pump and each of the one or more dirty pumps is plunger pump. 29. The method of claim 24, wherein each of the one or more clean pumps comprises a prime mover for supplying power, and wherein the prime mover is chosen from the group consisting of a diesel engine, a gas turbine, a steam turbine, an AC electric motor, and a DC electric motor. 30. The method of claim 24, wherein the one or more clean pumps are disposed remotely from the wellbore. 31. The method of claim 24, wherein the corrosive material is chosen from the group consisting of acids, petroleum, petroleum distillates, liquid Carbon Dioxide, liquid propane, low boiling point liquid hydrocarbons, Carbon Dioxide, and Nitrogen.
