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?
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?
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...
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...
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...
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...
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...
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.
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.
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...
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...
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...
