10 Questions To Ask Before Choosing SCADA Software
When creating SCADA specifications, engineering firms must focus on meeting the immediate start-up and operational requirements of the SCADA system. This often means specifying products with which they are familiar. The engineer wants to ensure that the new system meets all start-up requirements at a reasonable price. It is often difficult to look past the immediate project and consider long range plans, cost of system maintenance, and keeping your SCADA application current with evolving technology.

This poses unique challenges for the town's wastewater utility who must handle this extreme seasonal spike in usage.
Overcoming Water Scarcity Challenges On Providenciales Island
The residents and industries of Providenciales Island are completely dependent on fresh water produced by a single desalination plant. In 2007, ITT Flowtronex was hired to replace the plant’s overworked pumping system and add a booster pumping station to the distribution system. One of the challenges they faced in designing controls for the system was how to maintain the public water supply while the island’s undersized ground water storage tanks were removed and replaced with a large single tank in the same location, a three to four month process.
