Dnk, The biosolids, or sludge, from the sewage treatment plant just down the way from the water replenishment facility is trucked out and composted...230,000 tons of it a year. Currently, the wastewater is all sent out a pipe 4.5 miles offshore and discharged in about 200' of water. Many believe that it's the source of bacteria that often forces beach closures. The new plant will take a load off of this discharge....until population growth catches up with the whole thing again.
Yes, the large box is the peckerhead. Inside is bus with the standard NEMA 2 hole pattern so in this case it's just a standard MV termination. We are going to have to turn them 90 degrees because they are getting fed via cable tray that will run along side just to the right of the beam you can see. There are 3 tiers, 4160, 480 and controls. Like I said before the small box you can see is the heater termination box and there is another box on the other side, out of site, where the inlet/outlet temp, bearing temp and vibration RTD's terminate into a terminal strip. Electure, interesting tid bit of info. The water from this plant will come from OCSD plant 1 next door via a 96" pipe. It has already been treated but is still pretty stinky. The finished product will be split between being pumped into the ground water and pumped all the way up the Kramer basin near the 91/55 junction where it will settle naturally into the ground. They have had the Santa Ana river trail closed for some time installing that line.
Yes, the VFD manufacturer requires 8KV shielded or non shielded cable. We are using shielded per project specifications. It looks like we will go with 3M QT-III terminations. Believe it or not this project is still under the 96 NEC so if it wasn't for the spec non shielded would be an option.
