I have a short agricultural irrigation system (a main) that provides water to farmers. The head of the system is a canal with a structure that provides a constant head of water elevation during the season. There is no pump to deliver water to the customers…
Hello,
I am using Bentley HAMMER to model a pump system that pumps water from a reservoir at low head to a reservoir at high head. The difference in head between the two reservoirs is approximately 600 ft. I am trying to study the transient effects…
Hello, I am working on a project using SewerGems, as required by the client. We are semi-new to the software, but have a model built and looking for some guidance on how to efficiently model sag inlets.
We currently have the subcatchment routed to a…
I am modeling a sewer system that is a combination of gravity pipes and forcemains. Some of the forcemains have isolation valves that can be closed to route the flow differently. However, SewerGEMS does not have the isolation valve feature. How can a…

Hi,
I am a doing modelling for improvement of the existing system. Many location velocities are high and pressure is low. Even I tried to increase the pump capacity the pressure is not increased.
Please check the model in the below following link…
Hi,
I'm modelling a simple treatment system to determine the hydraulics between each component of the system. In a particular section of the model, I am pumping from a wet well up to a lagoon. Is there a way I can connect a pressurized pipe to a pond…
Dear Folks , I have run a model with Hydrogen sulfide analysis , after made the analysis i got the result for H2s in and out concentration , my question is : do we have a limit for H2S concentration in sewer pipe line ?? or do we have a code or standard…
Hello Bentley Community,
I know similar questions have been asked relating Surge Tanks in Penstock installation, but I want to be sure in my model and it's results.
So, I'm modelling using Bentley Hammer Connect Edition a penstock with three turbines…
My model consists of a reservoir from a higher elevation supplying water to two tanks at a lower elevation. The pipe leading to the tanks keeps going to a negative pressure despite the inclusion of air valves. How can I correct this?
I am looking for software recommendations for modeling the filling and emptying of navigation locks. Here are some requirements:
There is a network (manifold) of pressurized pipes feeding lockage chambers. A large culvert runs alongside the chambers…
I am designing a drainage system in which I need two pipes begining from an inlet (on different walls of the inlet) and going elsewhere. One pipe will act as an overflow option if the other reaches capacity. However Inroads S&S does not like the fact…
Dear All
I have watercad model from other consultant and I should review it. the model has two different (different in Head and Flow) Potable water pump stations and they very far from each others about 15 km, both pump stations are ultimately discharge…
I have a TCV in my model which do not work, for example when i close it, there is still a pressure in the node. But for some TCV's in my model they are all working.
I tried to redraw all the pipes and junctions but still the same thing happened.
File…
Dear Sir,
I am running a closed system with multiple pumps operating in parallel. The system has PBV that represents the pressure drops in the actual system elements. All elevations & hydraulic grades are set initially to zero ;however the system…
I would like to justify to a client the use of SewerGEMS instead of HEC-1.
I have a small watershed (200 acres), significantly urbanized with a storm drain network consisting of storm drains, pipelines, earth channels, concrete channels, detention…
If someone wants to model only the cascading flow downstream of an air-valve; that is, the transitional pressure to gravity type flow that might set up in a gravity trunk main or a sewer forcemain, they should take a look at the new WaterGEMS/WaterCAD…
