  • Tank Filling Above Hydraulic Grade of Reservoir

    I am attempting to model a raw water intake using a reservoir to model the river which provides flow to a circular well with vertical turbine pumps that deliver flow to a treatment plant. I have set downstream FCV's to accept 60 MGD from the pumps,…
  • How to attach an existing junction on an existing pipe line?

    I am working on a model in which many of the junctions are not on the existing pipeline. So, I want to attach the existing junction(which is not attached to the pipeline) to the existing pipeline by not creating a new junction on the pipeline and splitting…

  • Potable Water Distribution Design for communities - use of PRV's

    Hi all, I have a general question on the use of PRV's at individual services for a "closed" distribution system, i.e. pumps directly draw from a treated reservoir and feed to end-users with no elevated/pressure tank and storage elsewhere. I have come…
