Taille de la conduite principale d'alimentation vers chaque bouche d'incendie.

Question

<\/HEAD>Pour les 2800 bouches d'incendie en ville, je dois trouver les tailles des conduites principales d'alimentation en eau. La bouche d'incendie est généralement connectée à une longueur de tuyau, puis à une vanne, puis à un té. C'est la taille des conduites connectées aux tés dont j'ai besoin.<\/P><\/BODY><\/HTML>

The GIS guru who worked here let me know of a field in the hydrant feature class (PIPE_DIA) that has this data already; I had seen it before but never had to use it.

Thank you for thoughts and hints you have given,

Danke,

Lou,

The hydrant lateral lines are typically a standard diameter size.  Sometimes the diameter of the lateral may change depending on the size of the hydrant though.  Would it be possible to chat with your operations or the engineering/planning group to determine if there are any standards in place for the hydrant assemblies?  That may save a lot of additional effort, then just apply global to all or filter based on hydrant size, if necessary.  The nearest water main may be a few sizes larger than the hydrant lateral itself, so applying the standard from engineering/operations may be the more accurate play.  If you are concerned about the length of the lateral, you could start with setting them to the average length then enhance precision down the road.  Hydraulically the short length of the fire hydrant laterals will have negligible impact on headloss calculations - don't worry you are not alone, its a typical headache when dealing with many hydrants/laterals - answering the unknown.

Respectfully,

Martin
