See what I mean. Ha! My girlfriend couldn't navigate her way out of a wet paper bag (she barely knows her left from her right, and seems to think that I can see her finger pointing out of my right peripheral vision when she does navigate), but at least she doesn't nag when I drive and navigate...
A second alexcmmi suggestion. Especially if the material entering the well is a daily occurence. But you gotta hand it to the guy who designed the drainage piping for the facility, if it's capable of moving all that debris on regular basis...
Maybe you could even save the sheets, clothes...
I do not know of any AWWA standard that is directly related to B31.3. That said, I am also not familiar with B31.3. I would suggest contacting the Ductile Iron Pipe Research Association (www.dipra.org) and see if any correlation exists between the ANSI B31.3 and applicable AWWA/ANSI/ASTM...
As a piping estimator, I'm always interested in the purpose of equipment and general design in water and wastewater treatment plants. So this question is solely for my curiosity.
What is the purpose of a seal water line going into a pump casing? Does it fill some sort of diaphragm that seals...
I'll take a stab as well.
I'm assuming that this is exposed piping. Possibly flanged? If so, then it is possible that pipe lengths in the BOM are shorter than length as dimensioned on the isometric. Two possible scenarios,
1) The same reason that StressGuy has pointed out.
2) There may be...
I about fell out of my chair laughing when one of my fellow estimators found this in a specifications for a job in West Virginia. We called our tech division to see if we could get a Kevlar vest for our pipe. See item 15 towards the top of the page...
As a pipe estimator, I interpret that spec verbage to mean "as measure along the pipe centerline", NOT the horizontal (plan) or station distance.
In the case of a storm sewer, I would conceed that it is probably "ok" to do the estimate based on the horizontal (stationing) distance.
But, if I'm...
This color coding of lines is indeed for internal use only. By which I mean, only the drafters in our department will see these contract drawings.
The color coding has nothing to do with the review and revise process internally, in fact, we have a very "unstructured" peer review process for...
There has been much disagreement between the drafters at work about the following situation. Any opinions (particularly those with ASTM Y14 reference, if the topic is covered by ASTM Y14, so that it can be settled once and for all!)
I work for a piping supplier, and when we receive our...
Another instance in which I have seen swivel tees spec'd is when a fire hydrant is branching off of a water main (for the same reason I think as coloeng mentioned). You can install the fire hydrant plumb as well.
It seems that if it were coming through the door, it would be easy enough to spot. As you would be able to go down to that door and watch the water come in, or you would be able to see the rot and water damage around the bottom of that particular door.
My grandfather had the same problem on...
Since it is a gravity sewer, then that both helps and hurts I guess. A manhole would be acceptable in that instance. My question would be if it is possible to use a manhole, due to elevation requirements (ie do you have enough elevation change between where the ductile iron pipe exits from...
Is this a watermain, sewer forcemain, or gravity sewer main?
If it is a pressuized main, then a manhole would be out of the question (assuming of course that you are using the manhole to compensate for different pipe ODs).
If the PVC OD is equivalent to the ductile iron pipe OD (I apologize...
