| Question | Answer | Date |
| Is there an estimated date that the 2026 Process topics will be posted? Also, do we know when this year's Hydromantis practice simulator will be available? | The updated Process Control Event Rules, scenario question topics and practice version of the simulator are scheduled to be available by February 1, 2026 | 1/9/26 |
| Many of the videos for the math listed on https://rmwea.org/oc_process. | The links have been checked for all the recordings and most of the files included in the math training and all appear to be active and working. | 1/30/26 |
| What is the cost to purchase the software for process control simulator. | Please contact Spencer Snowling of Hatch to inquire about purchasing software. He can be reached at spencer.snowling@hatch.com | 1/30/26 |
| As of today (2/2/2026), when I click the link for the Hydromantis simulator, it is still listed as the 2025 version. Is there an updated 2026 version still yet to come? The description on the RMWEA page says that there is a 2026 version. | The link has been updated. | 2/8/26 |
| Can a print out of the Hydromantis Operations Challenge Process Control Event - Simulator Question Background Information print out be provided at regional competitions similar to WEFTEC? While this information is beneficial to look at during the 3 minute review period, it is significantly more valuable from a professional growth and development stand point to review after the individual competition(s).
