1. A method of mixing a liquid coagulant into a flowing volume of water in a piping conduit, the piping conduit having an outside diameter ranging from 16 inches to 94 inches, the method comprising the steps of:
directing the flowing volume of water flowing through a pipe spool which has been preinstalled as an integral component of the piping conduit, the pipe spool comprising an integral conduit portion comprising a length extending between an upstream end and a downstream end, the pipe spool further comprising a first manifold comprising a first upstream distal end, the first upstream distal end comprising a first upstream nozzle which extends into an interior of the integral conduit portion, the pipe spool further comprising a second manifold comprising a second upstream distal end, the second upstream distal end comprising a second upstream nozzle which extends into the interior of the integral conduit portion, wherein the second upstream nozzle is disposed diametrically opposite the first upstream nozzle, wherein the first upstream nozzle and the second upstream nozzle are disposed at a first axial position along the length;
delivering a pressurized flow of water into an inlet, wherein the pressurized flow of water is directed from the inlet to the first upstream nozzle and to the second upstream nozzle; and
injecting the liquid coagulant into a chemical injection quill, the chemical injection quill having an end which extends into the interior of the integral conduit portion and into the flowing volume of water resulting in a treated flow of water, the end disposed at a position between the first upstream nozzle and the second upstream nozzle.
