GTH Designs Solar-Powered RTU System For Remote Level and Flow Monitoring
In 2014 the Bureau of Indian Health Services issued an RFQ to modernize the control systems for the Fort Independence tribe. The goal was to ensure future years of continued service, support, reliability and component availability. Although the George T. Hall Company (GTH) was not the lowest responsive bidder our organization offered the best solution and was awarded the project.

The Challenge
The well control and monitoring existing system did not include flow rate monitoring or well level monitoring. Trenching to existing wells and tapping of the existing header pipe for an insertion flow meter would be required. Tank monitoring required a submersible well level transmitter and solar powered RTU to transmit level via radio for well pump calls to fill the tank.

The Team
The GTH office in Nevada is 250 miles away from the site location, therefore a precisely engineered and tested system was paramount to the project success. Working with tribal personnel our two field technicians we were able to install and startup all of the equipment in a one week period. Our services included system engineering, programming, project management, extensive in house testing, installation and startup.

The Solution
As an authorized solution partner for Schneider Electric we utilized the Modicon M340 PAC controller for the well pump control system with a Magelis touch screen interface for system monitoring and control. Future remote monitoring and control will be possible via the web interface included with the Magelis system. Results of the system upgrade have been positive with overall performance and monitoring being improved resulting in less man power required to oversee the water system.
