    Large Stormwater Hydraulic Pump Manufacturers

    Yes, we can use axial flow pumps and the TDH is only 16.2 ft.

    Large Stormwater Hydraulic Pump Manufacturers

    I am looking for manufacturers of stormwater pumps capable of pumping at 67,500 gpm each (2 total). I have information from MWI and I need to contact other manufacturers. Does anyone know of another pump manufacturer who builds stormwater pumps this size?

    PE from project management.

    You will need to prove that your work experience is in engineering and you will need a PE to sign off for all of your years of experience. I am not sure if there is a PE at your new PM job, but if not you may not be eligible to sit for the PE exam. How do you like working in PM versus engineering?

    use of Treated sewage effluent for construction

    The WWTP where they get this treated effluent must have a land application NPDES permit to discharge onto soil and this permit has a specific site where the effluent must be discharged. I have never heard of a contractor wanting to use treated effluent for compaction and I have never heard of...

    WaterCAD and AutoCAD

    Some versions of AutoCAD are not comapatable with WaterCAD. Contact Haested to find out which version of AutoCAD is most compatable with your version of WaterCAD. You will be able to bring in pics/maps/etc into AutoCAD using AutoCAD Map. You can do all of your line work in there and tranfer...

    Sewer Force Mains On Top of One Another

    I would make an effort to coordinate the two force mains into one. The POTW will not accept two force mains on top of one another due to lack of access for normal operation and maintenance. Save your client some money and coordinate with the other pump station project. You may even be able to...

    Forcemain - Material and Cost

    It would be easiest to use 2" (I like SDR 11) HDPE pipe. It comes in a roll of probably at least 1000 ft (maybe more). You can install via horizontal directional drilling without even having to dig a trench. Very easy and the cost should be about the same or less as open trench for a 3000 ft...

    WaterCAD questions

    You can contact Bentley to get an "upgraded" version of WaterCAD to allow you to use more components in your model. I would be cautious trying to break the system into two 5000 component systems, unless you have a very definitive break point where the output from one model could be used as the...

    Directional Drilling Question

    I would also be worried about how the deformation will effect your connection to addtional fittings. I don't think the manufacturer makes joints or fittings for a 5" x 2" oblong pipe.

    Sewer Force Main Condition Assessment

    We don't have access to the inside of the force main like you would for a gravity sewer line, so the laser profiling is not really an option. Also, we need to keep the force main active during inspection.

    Sewer Force Main Condition Assessment

    fbs international doesn't think their guided wave technology will provide the results I am looking for on a DIP line. I am currently talking to a pipe inspection company, Acuren, that regularly serves the oil pipe industry. They have a digital radiography technology that they feel can provide...

    Sewer Force Main Condition Assessment

    alexcmmi, thanks for the helpful info. It sounds like you are in a flat coastal area. Are you in the SE? I have been looking at pricing for the ultrasonic pipe wall profiling. Do you have any cost information for this? How long ago did you use this technology? The failure was at a high...

    jorton, where do you work? That sounds like a good office to be in.

    Sewer Force Main Condition Assessment

    Internal corrosion from hydrogen sulfide is the cause. The cementitious liner was gone in 4 of 5 coupons. We sampled at high points on the line. I know why and how the line is corroding, but I need to find a technique for examining the degree of corrosion, i.e. a condition assessment. Your...

    Sewer Force Main Condition Assessment

    I am trying to assess the condition of a 24" DIP sewer force main. There have been previous failures on the 20,000 LF line and I know that replacement is unavoidable, but I am trying to determine when I will need to replace the line. There is an abundance of technology for leak detection...

    Engineers turned Brewmasters

    A lot of people like beer, but not many people brew there own. My point was that of the homebrewers I know, engineering is the most common profession by far. Making whiskey requires a still, which is a pretty serious equipment commitment. I don't think the gov would mind you making some...

    Engineers turned Brewmasters

    Surely you have had the urge to start a brewery. Have you ever given it any real consideration? I am a young engineer who just got my PE, but I am not sure that this is what I want to do the rest of my life. I enjoy the project management and business development side of my consulting work...

    Engineers turned Brewmasters

    I have been homebrewing for 2 years now. During this time I have noticed a remarkable correlation between engineers and homebrewers. The science behind brewing seems very appealing to the engineering type and it is indeed a great hobby. Naturally, every homebrewer has thought about opening...

    Certificate in Project Management

    I took some courses and got my PMP about 1.5 years ago. I enjoyed learning and found the information very applicable to my work as a consultant. My employer, however, was not very supportive and my career has yet to benefit from my new title. Overall, I am glad that I did it and I now have...
