Tamaño de la tubería principal alimentadora a cada hidrante.

Question

<\/HEAD>Para los 2800 hidrantes en la ciudad, necesito encontrar los tamaños de las tuberías principales alimentadoras de agua. El hidrante generalmente está conectado a un tramo de tubería, luego una válvula, luego una tee. Es el tamaño de las tuberías conectadas a las tees lo que necesito.<\/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
