    Trunk Sewers and Water Mains

    Well, for starters, the size (diameter) difference between trunk sewers and water mains is very likely to be significant, but you also have materials, gravity vs. pressure flow, etc. You may very well have the required expertise; the recruiting agency people are just parroting some written...

    Civil engineering technology bachelors degree and job outlook for this degree

    Draftsmen are being phased out. This should be pretty clear by now. GIS and BIM are indeed hot right now, and users typically have a Geography (for GIS) or engineering degree. To be a rodman, inspector, etc., you don't need a BS in Eng. or even in Eng. Techology, and their salaries reflect...

    FE / PE exam approach

    I think that if NC wants to see four years of experience after passing the FE exam, they will most likely make you wait until you have such experience before granting you the NC PE license by comity or reciprocity. It's best to check with them (NC) before assuming that they'll waive their...

    Aeration Piping Question

    Agree with the two posts above by bimr and stanier. So what if the contractor has CS pipe laying around. Are you going to redo your heat expansion and insulation requirement calcs? Will the contractor pay for that? What about corrosion concerns? You (and the owner) have little to gain...

    Stainless steel is what one would normally use.

    Freelance HVAC Engineer

    My take on this issue is a little different. As the economy seems to be picking up at a snail's pace, many small to medium size design companies often find themselves in a situation where they have more work than they can handle, although such work will not last long enough to justify hiring...

    TDS or TSS?

    TDS and TSS are mutually exclusive. Solids are dissolved or not; if they are not, they will remain suspended or they will settle out. Total Solids include TDS, TSS and settleable solids. 5.8 Total Solids http://water.epa.gov/type/rsl/monitoring/vms58.cfm

    3 years unemployment

    I agree with csd72, I wouldn't pursue a PhD-unless I intended to do R&D or teach. Your MS degree is, however, a big plus in my opinion. I think that you need to get out of DC and go where the jobs are, even if you just stay with friends for a few weeks. The reason is that even if relocation is...

    Headhunter vs Sending Resumes, Pros/Cons, Recomendations

    I agree with cvg up above. You should never, ever, pay a headhunter. They get paid by the hiring company, sometimes as much as 35% of your starting annual salary. Companies usually contract with a headhunter because they do not want to have to deal with a flood of resumes, 90% of which are for...

    Understanding Water Treatment Fundamentals

    Any good process chemistry book will be helpful. I'm not familiar with the one recommended by the previous poster, but my favorite is an old book by Benefield and Randall. Sawyer and McCarthy (sp?) was also very popular, perhaps it still is. Infilco/Degremont and Nalco had books as well, mostly...
