At my previous employer we deployed iPad Airs and iPad Air2s in the field with work crews.  Devices were equipped with Otter Boxes and unlimited cellular data plans.  All of the data accessed was in the form of Hosted services or Esri base maps.  The units and capabilities they offered were well received by the field staff.  In addition to access to the information via maps, they likes having the ability to submit updates directly through the application.  They also like the increase communications ability imessaging, emailing photos, and facetime over just cellular or radio communications. When out doors we found the internal GPS suitable for getting them in the neighborhood still relied on dedicated Trimble GPS gear when verifiable accuracy was required. Currently I am working on deploying Andriod based Asus ZenPad 10s with my new employer.  Setup is slightly different in that we are using the collector app versus the original ArcGIS ios app.  We are currently seeing some slower then expected performance but are still trying to tweak the map to maximize performance.  The internal GPS is very unreliable ranging from +/- 2 to 50 ft. We also need to explore better utilization of Android's native communication tools.  While it is still early I am a little disappointed with these devices.  Will hold off final opinion until more testing is done.   ...

What your talking about doing is hydraulic modeling as is usually done is a separate software package.  The utility model isn't really equipped to do the complex calculations needed to determine flow in these types of situations.  In fact as the conditions change (tank levels, pumps turn on/off, demand patterns) the flow direction can vary pretty dramatically in a water system.  The flow directions works well with sewer systems sue to their lack of loops and one way flow design.  Geometric networks for water usage is limited mostly to connectivity tracing and isolation.  ...

Your original Data is in DD MM.ss format meaning the 1st group of numbers represent Degrees the second groups present Minutes with seconds shown as a decimal. you should convert the numbers to Decimal Degrees DD.mmss this will eliminate and spaces and prevent and translation errors.  Also make sure you indicate Longitude as the X Coordinate and Latitude as the Y coordinate.  Lastly check you data to make sure none of the Longitudes are W and Latitudes are S as these would require a leading '-' sign to indicate direction. ...

You can do it at the Feature Service level.  This thread https://community.esri.com/thread/183374-disable-geometry-edits-in-collector should cover what you need. ... View more

To add a field  do this open ArcMap > open Attribute Table > from table options select "Add Field" this will allow you to define your field. To delete a field open ArcMap > open Attribute Table > right click on field to be deleted an choose "Delete Field" both of these actions need to be done outside of a edit session.  If you need to copy data over you will want to create the new field first.  If you want to reuse the field name you will need to delete the existing field first. ...

When you use the term "web app" do you really men web map.  Collector consumes published web maps not applications.  But the web map should be available as soon as published in AGOL.  Possible sticking points can be how the data and map are shared.  Also what type of device are you running collector on make sure you have internet connectivity and that collector is up to date.  If all of this checks out try forcing a stop on the app and reopening as this might force a refresh.  On thing I have seen is that on MS surfaces sometimes the app will not connect to the internet even though the tablet has connectivity.  I only have one of these and don't really use it that much so I haven't spent any time looking into the reason.

While I work at a water utility we I deal with field implementations a lot.  At my previous job I utilized iPad Air2s with several of Esri apps utilizing AGOL hosted solutions.  At my current location we are just starting implementation of field services and will utilize Android devices.  We will be using Samsung Galaxy Tabs2 or similar.  The change is due to existing infrastructure not any problems with the iPad solution.  I will be utilizing ArcGIS online but hope to shift away from hosted services to local ArcGIS Server services once we have completed our Database roll out.  One big thing to consider in the process of choosing hardware software is how you will configure and manage the devices as this is a big departure from dealing with regular desktop server hardware software.  #field workers‌ #mobile tools‌ ...

I am pretty sure everything you need is on the appliance, the concept is you can put everything onsite and behind your firewall and need no external connection.  It was developed for 3 letter government agencies who cannot be connected to external networks. ... View more

If you are worried about dependence on Esri's online basemaps for your apps you could always look at their Data Appliance for ArcGIS it lets you bring Esri's data on premises.  Most of the mobile apps do have offline capabilities that let you work disconnected so maybe a good idea to download key data and application to disconnect mode prior to impending storm.  I would also think given emergency responders need to communicate and utilize mobile equipment data that the re[air or establishment of temporary cellular networks will be high priority and as long as your organization is considered provide vital services you should be given access to these even if the public is not.  ...
