WaterCraft: demands, fire flow, outages and water age

With the WaterCraft add-on, turn customers into demands on your water mains, check the flow available at every hydrant, see which main outage hurts most, and follow water age and chlorine through a day.

Written for CivilCraft 0.9. The same help is inside the app: press F1.

WaterCraft is an add-on that works on the water network you already drew with the Water mains tools. It adds a tab to the right-hand panel with four sections.

What you'll do

  • Put customers on the network as demands.
  • Find the hydrants that fall short of the flow you need.
  • Find the mains whose loss matters most.
  • Find old water and low chlorine.

Steps

  1. Open Settings › Add-ons and switch on WaterCraft (water distribution). A WaterCraft tab appears in the right-hand panel.
  2. Draw a reservoir, junctions and pipes with the Water mains tools first (see Water mains). Without a network the tab tells you to do that.
  3. Under Demands, paste one customer per line: id, x, y, kind, amount. Choose the Peaking factor and the Hourly pattern (residential day, commercial day, flat, or keep the pattern as it is). Press Check to see where each customer lands (the nearest junction), then Put into the network. Undo takes the demands back.
  4. Under Fire flow, set the needed flow and the residual pressure, choose whether the residual is held At the hydrant only or Everywhere in the system (stricter), and press Run. Each hydrant is listed worst first, as meets or short.
  5. Under Which main matters most, choose one pipe at a time or one valved section at a time and press Run. Each outage shows the demand cut off, the junctions cut off, the junctions newly under the minimum pressure and the lowest pressure left.
  6. Under Water age and chlorine, choose what to follow (water age, chlorine or a source trace), set the hours to run and the limits you want, and press Run. Junctions outside your limits are listed.
  7. Press Save as CSV under any table to keep it.

Notes

  • The needed fire flow and the use per home or per acre are starting values, not standards. Use your utility's own figures.
  • A pipe cut partly by a valve is closed whole, so the outage shown is slightly worse than a real one.
  • Run the water-quality section long enough for the daily pattern to repeat before you read the last day.
  • Stop ends a long run early; the list then shows only what was done.
  • Your network stays in this project and on this computer. Nothing is sent anywhere.
