幾何ネットワークのソースとシンク

Question

<\/HEAD>こんにちは、GeoNetコミュニティの皆さん。私は下水道システムと水／リサイクルシステムの幾何ネットワークの流れ方向を確立しようとしています。ソースとシンクは設定しましたが、ポンプ／リフトステーションが両方の役割を持つため、どのように分類すべきか悩んでいます。その結果、すべてのパイプラインの流れが不定となっています。何かアドバイスをいただけると助かります。<\/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?
