Finding Sewer Lift Station Flow

EvanMyers1 — Tue, 29 Oct 2019 19:15:11 GMT

Hello Everyone,

I have been given the task to find the flow of our lift stations, specifically the ones that flow into another lift station. I have attempted several different ways of doing this but none of them seem to get very far. To have a better idea what I am talking about, here is an example of the data:

(The data goes to a main on the left side and continues upwards)

I want to insert the name of Lift Station #1 into a field for the linear features with the red arrows and then a combination of #1 and #2 to the linear features after Lift Station #2. I feel like this can be accomplished using Network Analyst, but a large majority of the linear dataset doesn't the correct direction.

If anyone has an idea of how this can be accomplished that would be great!

Evan,

Wanted to ask - when you mentioned finding the flow of the lift stations, where you looking for a:"flow direction" or b:"volume of flow" or flowrate (i.e. 1 cubic foot/per second). 2 different variables/different answers. Also once knowing a or b, what is the next step, what are they looking to do? Thanks for posting the question, look forward to your response - talk soon!

Respectfully,

Martin

Basically, I would like to transfer the name of a lift station to the connecting Pressure Main but only if the main goes down stream. I've attached a picture of another spot in our service area. I managed to get the name transferred to the 1st main intersecting the lift station using Spatial Join but I don't know how to get the rest of the pipes. The letters in green is what I want to happen. One of the issues I'm running into is pipes getting their named replaced or the wrong name being assigned because of the way Spatial Join works.

If you are using ArcMap and your data is in a geometric network than you should be able to do this with the attribute assistant in this Solution Template - Water Geometric Network Editing and Analysis | ArcGIS Solutions for Water

Leaving a quick update how I believe was the best way accomplishing this.

I created a Network Dataset, set up some basic rules, and then, using Pro, I created a Closest Facility layer and made the treatment plants Facilities and the Pump Stations Incidents. This created a single Route line for each lift station with an origin and destination name as well as the proper direction of flow.

My next step is doing a combination of splits and spatial joins on the existing pipes and the Routes to create the desired results.

Thank you all for the help!
