The "wet well" is the structure that holds the water (potable or wastewater or stormwater). A "dry well" is generally an underground structure adjacent to the wet well where the mechanical equipment is housed (i.e. the pumps, valves, maybe the MCCs and switchgear)...
Unfortunately, this is when the backhoe is called to the site....
If you have more time, perhaps sending another camera (with a stronger retreival cable) to determine the problem would be a possibility? I have heard of folks using a jetter to pull a chain/cable past the camera to the next...
ABS is certainly one of the more relatively common pump manufacturers in the US. They compete directly with Fairbanks Morse, A-C, Flowserve, and Patterson (in the smaller patterson ranges). I suggest asking for references in your area...that should demonstrate the level of their local...
Sewerguy,
regarding VFD use with blowers...there have been problems with vibration of piping and silencers when VFDs are used with positive displacement blowers. The problems normally only occur a specific speeds, but this should be a major concern and be addressed in the spec. It can work as...
You're going to have to tell us what state you're in...generally each state or region has its own, industry accepted source for that information. Once we know, perhaps someone in this forum from that area can help you find the information.
I believe you are looking for "Recommended Standards for Wastewater Facilities". There are a couple of other standards also known as the 10 States Standards (for swimming pools, septic systems, and potable water treatment facilities). They're all available for a relatively low price...
I think you're a little confused. There is no need to plug the hole. The new pipe remains inactive until the top of the existing pipe is broken. The existing pipe is broken inside of the new manhole to allow the flow from the new pipe to enter it. The existing pipe isn't broken until the new...
This will largely depend on the program you wish to enter. As a general rule, unless you have extensive experience in your chosen field of study or a post-graduate degree in a related field, your advisory board will require a minimum number of post-graduate classes before "officially"...
I've always seen the annular space filled, since it minimizes movement of the carrier pipe and helps reduce the potential for casing pipe collapse. The casing should be designed to withstand the load from the roadway, so transferring the forces isn't an issue. Differential settlement of the...
First, I would say that plastic would generally be better than sheet metal for that type of application. Second, is there a particular reason that you feel that active ventilation (exhaust fan) is necessary to exhaust from the wet well. In all applications I've seen, a vent is provided...
This sounds like the same requirements for sanitary sewers near watermains and this is done very frequently in that instance, so it may be difficult to justify not sealing it from that standpoint. The idea is to get joints (the weak part as far as leakage) away from the watermain.
While I've...
Go to the Fairbanks Morse site and try out H2Optimize. It allows you to look through any of the Pentair owned pumps (FM, Hydromatic, Aurora).

Also, Patterson Pumps offers a similar program integrated to their website.

Good luck. I'm...
What type of forcemain is this? 2" seems like it would serve a single home or building. I'll defer to the others in this forum, but I would assume that an air relief valve on a small system like this one is not required. The safety factor provided on small piping systems is so large...
To add to the discussion, pipe bursting can cause heaving above the pipe if there isn't sufficient cover. That sounds like it could be a concern in your case.
Along the same lines as the previous post, there are some areas where a vacuum system is used as well. As the previous post, these are normally used in areas with undulating topography that precludes gravity sewers or in areas where there are fewer customers. Something to consider...I have no...
