  • How do I check that my pump design is correct and optimal (for pumping water to multiple overhead tanks)?

    Dear all, I have a situation where pipe network is laid upto 12 overhead tanks. Now I need to design pump to feed water to this network, so that daily demands at the tanks are met. So far, what I have tried is- defined a 1 design point pump with an…
  • 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…
