The Turbidity meters can be ordered with a flow meter which could be wired into PLC via the controller and act as both a meter and flow switch. That would make the external ones redundant. They also come with a needle valve to regulate flow to be installed on the outlet side of the meter. Similarly, the Chlorine analyzer flow through cell has both a needle type flow control valve and a flow switch. Along with a float style flow meter.

1” piping appears excessive given the minimal flows that run through this equipment. ¾” piping is typical for influent, then any branches that feed individual components are typically ½”; the 1” will add unnecessary cost. Examples- turbidity meters require 100-1000ml/min (.0264-.264 gpm) flowrate. The streaming current requires 1.5-2.5 GPM. The chlorine analyzer requires 30-50 liter/hr (.1321-.2201 gpm).

The Coagulant Supply line after the pump on Sub Sheet No. 110D404 it says ½” Coag in Containment pipe to Rapid Mixer, however on Sub sheet No. 110D904 note 5 it says the pipe should be Double Containment. In the specifications for the Double containment it calls out a spears product that the minimum size is 1”. Should we be running a ½” tube in a regular schedule 80 PVC pipe per page 158? Or if we need to run the 1” Double Containment per page 163?

The Same line also call out Note 5 which states, “Transition to Double Containment Piping where Illustrated on Drawings”. Is this drawing requiring us to run these lines as a 1” Double containment system inside another containment pipe? Or do we run 1” tubing inside the PVC Carrier pipe?
