Sources et puits du réseau géométrique

Question

<\/HEAD>Bonjour communauté GeoNet, j'essaie d'établir les directions de flux pour notre réseau géométrique sur un système d'égouts et un système d'eau/recyclage. J'ai placé mes sources et puits, mais je suis perplexe quant à la manière de catégoriser les stations de pompage/relevage car elles sont les deux. Cela entraîne que tous les pipelines ont un flux indéterminé. Toute orientation serait appréciée.<\/P><\/BODY><\/HTML>

@Charles_Darwin  you were given some bad info!  Thousands of wastewater utilities have used the geometric network to represent their sewer systems, now they are implementing the utility network.

Hello,

I hope it's not too late to ask this, but I had a GIS manager tell me that waste water (sewer systems) don't use geometric networks. He told me they don't use geometric networks because geometric networks are used to change direction of flow of electricity for maintenance. He said something along the lines of that. But, does waste water systems use geometric networks?

Thank you for the response Martin. Our system has quite a few forcemains (about 170 line segments). I am still having everything indeterminate flow. I thought I cannot have multiple sources/sinks in the same linear segment?
