Topic: The City of Wichita Falls Indirect Potable Reuse project

Speaker: Daniel Nix

Born and raised in Wichita Falls, Daniel graduated Midwestern State University with a Bachelor of Science Degree in Environmental Science.  He has worked for the City of Wichita Falls for over 29 years, starting as a Utilities System Worker 1 with the Water Distribution Division and has worked his way up the ladder to Utilities Operations Manager, a position he has held since 2008.  He possess’ a Grade A Water License and Grade C Wastewater License from the State of Texas.  He is extremely active in the Water Industry; serving on the Board of Directors for the American Water Works Association, serving on numerous committees for Filtration and Reuse, authoring an award winning book and developing a Specialty License Plate in the State of Texas that promotes Water Conservation.

Daniel has participated in the contingency planning for the last 2 droughts in Wichita Falls, as well as overseeing the last several revisions of the City’s Water Conservation and Drought Contingency Plans.  He finalized the construction on the Reverse Osmosis Plant in 2008, and successfully brought it into operation.  He was very familiar with the Reuse initiatives that were spawned from the 1990’s drought, so when the most recent drought showed no signs of abating, Daniel was quick to bring all of the past reuse studies to the attention of Administration and worked on developing the Conceptual Design of the Temporary Direct Potable Reuse (DPR).  He was part of the team that engaged the TCEQ on developing guidelines for the DPR, planning the route of the pipeline, and overseeing the Verification Studies to prove the system was safe.  In conjunction with the DPR work, Daniel has been part of the team that has developed the Permanent Indirect Potable Reuse (IPR) system that will go on line in 2017.  Through his work on the DPR and IPR systems, Daniel’s guidance is sought after by other Municipalities and States that are pursuing Reuse initiatives.

Daniel’s wife Cheryl is the Director of the Science Program at McNiel Junior High School, and teaches 7th Grade Science.  They have been married for 15 years, and have two children; Matthew and Alexis.  Matthew is a Sophomore Accounting Major at MSU and Alexis is in the 7th Grade at McNiel, participating in Volleyball and Choir.  The entire family is active in volunteering their time with equine therapy for challenged individuals at Whispers of Hope.
