The 40-37 Building <br />system is to be extended to serve Clean, Seal and Paint <br />enclosures in New Buildings 40-36, -35, -34, -26 and -25. The new <br />system would tie into the existing Factory Waste Water Piping <br />System which terminates at the Waste Treatment Plant. <br />City Officials had not had the opportunity to comment on the <br />Industrial Waste Piping Sytem serving the new buildings. <br />It was agreed that welded black steel pipe would be acceptable <br />for conveying Industrial Waste Water from all of the sources <br />noted above. The piping must be flooded at all times to prevent <br />or minimize oxidation of interior pipe surfaces. <br />Larry Wehmhoefer <br />Facilities Engineer, Mechanical <br />T-6153, OH-24 <br />266-2818 <br />
