Flexible Chlorine Injection Pacing with Cloud-Based SCADA - White Deer, TX - Case Study

The City of White Deer, Texas is located in North Texas and serves approximately 500 water taps.
The water distribution operation includes a flow-pacing chlorine injection valve. For the past 10 years, the utility had a custom programmed, radio-based SCADA system in place and it worked the way the operators needed it to. After several years, the radio communications became unreliable and the system experienced several connection dropouts. The system relied on constant connectivity to ensure functional controls and proper chlorine injection rates. On the rare occasion that their SCADA system sent alarms, the utility operators were required to drive out to one of the sites where the local HMI screen was to determine what the problems were. Only after that could they determine what tools or personnel were needed to correct the problem.

Because of this development, the City of White Deer went through the process of seeking alternative technologies to facilitate their needs. One of the key criteria of this search was that the SCADA vendor would be able to handle controlling the chlorine injection system that was in place so the utility did not have to completely replace the existing infrastructure. The City of White Deer examined vendors from the radio and cellular backgrounds and determine that High Tide Technologies, a cloud-based SCADA system, would fit their needs as well as their budget.
